There are various technologies emerging from Aeronautics and Aerospace fields which results into
different problems being solved yet there are some which will be very beneficiary in near future for military as
well as for civil purpose. We as students are working on a problem which will benefit in our near future. In our
project we are designing an electric propelled HDATV (heavy duty air transport vehicle) which utilizes VTOL
technology. The aircraft which we are designing consists of fuselage with two nacelles at the end of high placed
fixed wing and two horizontal stabilizers and a vertical stabilizer along with it. The fuselage and the nacelles are
lifting bodies that are configured to jointly form an aerodynamic lifting body which cooperates with the horizontal
stabilizer to provide aerodynamic lift to the aircraft in forward flight. The nacelles houses two propellers which
are highly pitched and powered by the BLDC Motors operating in counter-rotating directions. The nacelles will
be designed to perform tilting operation in the direction of flight whenever necessary. The aircraft will be
unmanned and controlled via radio controller. The main aim of our project is to demonstrate the use of electric
VTOL technology and to perform basic tasks like avoiding obstacles, to carry loads and to perform some air
manoeuvres.

Unmanned Aerial Vehicles (UAVs): An Emerging Technology for Logisticsinventionjournals
Unmanned Aerial Vehicles (UVAs), commonly known as drones have extensively been utilized in military operations during the last decade for surveillance, monitoring enemy activities, collecting information, and even attacking military targets and terrorist hideouts. They are also increasingly finding uses in civil applications, such as policing and firefighting and nonmilitary work, such as inspection of power lines and pipelines. Furthermore, corporations utilized them in commercial applications, such as agriculture, logistics, delivering small packages to rough terrain locations, and medication to emergency locations. UAVs are often preferred for missions that are too ―dull, dirty or dangerous‖ for manned aircraft. This paper is exploratory in nature and describes the past and current usage in logistics and military. It further explores design and development considerations of UAVs. This is an emerging technology that will change the landscape of logistics and supply chain management. This research article provides a basic foundation to academicians, researchers, and commercial companies.

A collection of some of the most influential and important aircraft designs in history. These aircraft aren't necessarily the most famous, but each have played vital roles in the evolution of aviation.
: The main objective of this paper is the systematic description of the current research and
development of small or miniature unmanned aerial vehicles and micro aerial vehicles, with a focus on
rotary wing vehicles. In recent times, unmanned/Micro aerial vehicles have been operated across the
world; they have also been the subject of considerable research. In particular, UAVs/MAVs with rotary
wings have been expected to perform various tasks such as monitoring at fixed points and surveillance
from the sky since they can perform not only perform static flights by hovering but also achieve vertical
takeoffs and landing. Helicopters have been used for personnel transport, carrying goods, spreading
information, and performing monitoring duties for long periods. A manned helicopter has to be used for
all these duties. On the other hand, unmanned helicopters that can be operated by radio control have
been developed as a hobby. Since unmanned helicopters are often superior to manned helicopters in
terms of cost and safety, in recent years, accomplishing tasks using unmanned helicopters has become
popular. Considerable expertise is required to operate unmanned helicopters by radio control, and
hence, vast labor resources are employed to train operators. Moreover, it is impossible to operate
unmanned helicopters outside visual areas because of lack of radio control, and the working area is
hence limited remarkably. For solving the above problems, it is necessary to realize autonomous
control of unmanned helicopters. However, no general method for designing the small unmanned
helicopters has been developed yet – today, various design techniques by different study groups using
different helicopters exist. In this paper the conceptual design process is explained.
The content provides the evolution of the Unmanned Aerial Vehicles from the very beginning to the present.
Starting from 1849 with Balloons, the UAVs have now evolved so much with the technology and have gained a lot importance in different sectors.

Structural and Morphological Studies of Nano Composite Polymer Gel Electroly...vivatechijri
n today’s society, we stand before a change in energy scarcity. As our civilization grows, many
countries in thedeveloping world seek to have the standard of living that has been exclusive to a few nations, so
their arises a need in thedevelopment of technology that is compatible enough with the resources provided by
nature in order to have sustainabledevelopment to all class of the society. In order to overcomethe prevailing
challenges of huge energy crises in near future, there is an urgent need for the development of electrical
vehiclesor hybrid electrical vehicles with low CO2 emissions using renewable energy sources. In view of the
above, electrochemicalcapacitors can fulfil the requirements to some extent.Preparation of nano composite
polymer gel electrolyte is the best optional product to overcome these problems. When fillers are added or
dispersed to the polymer gel electrolyte, amorphous or porous nature of electrolyte increases which enhances
the liquid absorbing quality of polymer and helps in removing the drawbacks of polymer gel electrolytes such as
leakage, poor mechanical and thermal stability etc. In this work dispersion of SiO2 nano filler is done in the
[PVdF (HFP)-PC-Mg (ClO4)2] for the synthesis of nano composite PGE [PVdF (HFP)-PC-MgClO4- SiO2].
Optimization and characterization was carried out by using various techniques.

METHODS FOR DETECTION OF COMMON ADULTERANTS IN FOODvivatechijri
Food is essential forliving. Food adulteration deceives consumers and can endanger their health. The
purpose of this document is to list common food adulterant methods commonly found in India. An adulterant is
a substance found in other substances such as food, cosmetics, pharmaceuticals, fuels, or other chemicals that
compromise the safety or effectiveness of that substance. The addition of adulterants is called adulteration. The
most common reason for adulteration is the use of undeclared materials by manufacturers that are cheaper than
the correct and declared ones. The adulterants can be harmful or reduce the effectiveness of the product, or
they can be harmless.
The novel ideas of being a entrepreneur is a key for everyone to get in the hustle, but developing a

An Alternative to Hard Drives in the Coming Future:DNA-BASED DATA STORAGEvivatechijri
Demand for data storage is growing exponentially, but the capacity of existing storage media is not keeping up, there emerges a requirement for a storage medium with high capacity, high storage density, and possibility to face up to extreme environmental conditions. According to a research in 2018, every minute Google conducted 3.88 million searches, other people posted 49,000 photos on Instagram, sent 159,362,760 e-mails, tweeted 473,000 times and watched 4.33 million videos on YouTube. In 2020 it estimated a creation of 1.7 megabytes of knowledge per second per person globally, which translates to about 418 zettabytes during a single year. The magnetic or optical data-storage systems that currently hold this volume of 0s and 1s typically cannot last for quite a century. Running data centres takes vast amounts of energy. In short, we are close to have a substantial data-storage problem which will only become more severe over time. Deoxyribonucleic acid (DNA) are often potentially used for these purposes because it isn't much different from the traditional method utilized in a computer. DNA’s information density is notable, 215 petabytes or 215 million gigabytes of data can be stored in just one gram of DNA. First we can encode all data at a molecular level and then store it in a medium that will last for a while and not become out-dated just like floppy disks. Due to the improved techniques for reading and writing DNA, a rapid increase is observed in the amount of possible data storage in DNA.
The usage of chatbots has increased tremendously since past few years. A conversational interface is an interface that the user can interact with by means of a conversation. The conversation can occur by speech but also by text input. When a chatty interface uses text, it is also described as a chatbot or a conversational medium. During this study, the user experience factors of these so called chatbots were investigated. The prime objective is “to spot the state of the art in chatbot usability and applied human-computer interaction methodologies, to research the way to assess chatbots usability". Two sorts of chatbots are formulated, one with and one without personalisation factors. the planning of this research may be a two-by-two factorial design. The independent variables are the two chatbots (unpersonalised versus personalised) and thus the speci?c task or goal the user are ready to do with the chatbot within the ?nancial ?eld (a simple versus a posh task). The results are that there was no noteworthy interaction effect between personalisation and task on the user experience of chatbots. A signi?cant di?erence was found between the two tasks with regard to the user experience of chatbots, however this variation wasn't because of personalisation.

Cross Platform Development Using Fluttervivatechijri
Today the development of cross-platform mobile application has under the state of compromise. The developers are not willing to choose an alternative of either building the similar app many times for many operating systems or to accept a lowest common denominator and optimal solution that will going to trade the native speed, accuracy for portability. The Flutter is an open-source SDK for creating high-performance, high fidelity mobile apps for the development of iOS and Android. Few significant features of flutter are - Just-in-time compilation (JIT), Ahead- of-time compilation (AOT compilation) into a native (system-dependent) machine code so that the resulting binary file can execute natively. The Flutter’s hot reload functionality helps us to understand quickly and easily experiment, build UIs, add features, and fix bugs. Hot reload works by injecting updated source code files into the running Dart Virtual Machine (VM). With the help of Flutter, we believe that we would be having a solution that gives us the best of both worlds: hardware accelerated graphics and UI, powered by native ARM code, targeting both popular mobile operating systems.

Recommender System (RS) has emerged as a significant research interest that aims to assist users to seek out items online by providing suggestions that closely match their interests. Recommender system, an information filtering technology employed in many items is presented in internet sites as per the interest of users, and is implemented in applications like movies, music, venue, books, research articles, tourism and social media normally. Recommender systems research is usually supported comparisons of predictive accuracy: the higher the evaluation scores, the higher the recommender. One amongst the leading approaches was the utilization of advice systems to proactively recommend scholarly papers to individual researchers. In today's world, time has more value and therefore the researchers haven't any much time to spend on trying to find the proper articles in line with their research domain. Recommender Systems are designed to suggest users the things that best fit the user needs and preferences. Recommender systems typically produce an inventory of recommendations in one among two ways -through collaborative or content-based filtering. Additionally, both the general public and also the non-public used descriptive metadata are used. The scope of the advice is therefore limited to variety of documents which are either publicly available or which are granted copyright permits. Recommendation systems (RS) support users and developers of varied computer and software systems to beat information overload, perform information discovery tasks and approximate computation, among others.

Social media platform and Our right to privacyvivatechijri
The advancement of Information Technology has hastened the ability to disseminate information across the globe. In particular, the recent trends in ‘Social Networking’ have led to a spark in personally sensitive information being published on the World Wide Web. While such socially active websites are creative tools for expressing one’s personality it also entails serious privacy concerns. Thus, Social Networking websites could be termed a double edged sword. It is important for the law to keep abreast of these developments in technology. The purpose of this paper is to demonstrate the limits of extending existing laws to battle privacy intrusions in the Internet especially in the context of social networking. It is suggested that privacy specific legislation is the most appropriate means of protecting online privacy. In doing so it is important to maintain a balance between the competing right of expression, the failure of which may hinder the reaping of benefits offered by Internet technology

A Study of Tokenization of Real Estate Using Blockchain Technologyvivatechijri
Real estate is by far one of the most trusted investments that people have preferred, being a lucrative investment it provides a steady source of income in the form of lease and rents. Although there are numerous advantages, one of the key downsides of real estate investments is lack of liquidity. Thus, even though global real estate investments amount to about twice the size of investments in stock markets, the number of investors in the real estate market is significantly lower. Block chain technology has real potential in addressing the issues of liquidity and transparency, opening the market to even retail investors. Owing to the functionality and flexibility of creating Security Tokens, which are backed by real-world assets, real estate can be made liquid with the help of Special Purpose Vehicles. Tokens of ERC 777 standard, which represent fractional ownership of the real estate can be purchased by an investor and these tokens can also be listed on secondary exchanges. The robustness of Smart Contracts can enable the efficient transfer of tokens and seamless distribution of earnings amongst the investors. This work describes Ethereum blockchainbased solutions to make the existing Real Estate investment system much more efficient.

Abstract : There are various technologies emerging from Aeronautics and Aerospace fields which results into
different problems being solved yet there are some which will be very beneficiary in near future for military as
well as for civil purpose. We as students are working on a problem which will benefit in our near future. In our
project we are designing an electric propelled HDATV (heavy duty air transport vehicle) which utilizes VTOL
technology. The aircraft which we are designing consists of fuselage with two nacelles at the end of high placed
fixed wing and two horizontal stabilizers and a vertical stabilizer along with it. The fuselage and the nacelles are
lifting bodies that are configured to jointly form an aerodynamic lifting body which cooperates with the horizontal
stabilizer to provide aerodynamic lift to the aircraft in forward flight. The nacelles houses two propellers which
are highly pitched and powered by the BLDC Motors operating in counter-rotating directions. The nacelles will
be designed to perform tilting operation in the direction of flight whenever necessary. The aircraft will be
unmanned and controlled via radio controller. The main aim of our project is to demonstrate the use of electric
VTOL technology and to perform basic tasks like avoiding obstacles, to carry loads and to perform some air
manoeuvres.
Keywords – Vtol, Cad, Uav, Stol, Hovercraft, Airfoil, Amphibious Class.
I. INTRODUCTION
The Wright Brothers invented and flew the first airplane in 1903, recognized as "the first sustained and controlled
heavier-than-air powered flight". They built on the works of George Cayley dating from 1799, when he set forth
the concept of the modern airplane (and later built and flew models and successful passenger-carrying gliders).
Between 1867 and 1896, the German pioneer of human aviation Otto Lilienthal also studied heavier-than-air flight.
Following its limited use in WW1, aircraft technology continued to develop. Airplanes had a presence in all the
major battles of World War 2. The first Jet Aircraft was the German Heinkel He in 1939. The first Jet airliner, the
de Havilland Comet, was introduced in 1952. The Boeing 707, the first widely successful commercial jet, was in
commercial service for more than 50 years, from 1958 to at least 2013. In 1799, George Cayley set forth the concept
of the modern airplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control.

Cayley was building and flying models of fixed-wing aircraft as early as 1803, and he built a successful passenger-
carrying glider in 1853. In 1856, Frenchman Jean-Marie Le Bris made the first powered flight, by having his glider
"L Albatross artificiel" pulled by a horse on a beach. Then the Russian Alexander F. Mozhaisky also made some
innovative designs. In 1883, the American John J. Montgomery made a controlled flight in a glider. Other aviators
who made similar flights at that time were Otto Lilienthal, Percy Pilcher, and Octave Chanute.
Sir Hiram Maxim built a craft that weighed 3.5 tons, with a 110-foot (34 m) wingspan that was powered by two
360-horsepower (270 kW) steam engines driving two propellers. In 1894, his machine was tested with overhead
rails to prevent it from rising. The test showed that it had enough lift to take off. The craft was uncontrollable,
which Maxim, it is presumed, realized, because he subsequently abandoned work on it. World War I served as a
testbed for the use of the airplane as a weapon. Airplanes demonstrated their potential as mobile observation
platforms, then proved themselves to be machines of war capable of causing casualties to the enemy. The earliest
known aerial victory with a synchronized machine gun-armed fighter aircraft occurred in 1915, by German
Luftstreitkräfte Leutnant Kurt Wirtgen’s. Fighter aces appeared; the greatest (by number of Aerial Combat
victories) was Manfred von Richthofen. Following WWI, aircraft technology continued to develop.Alcock and
Brown crossed the Atlantic non-stop for the first time in 1919. The first international commercial flights took place
between the United States and Canada in 1919.Airplanes had a presence in all the major battles of World War II.
They were an essential component of the military strategies of the period, such as the German Blitzkrieg, The
Battle of Britain, and the American and Japanese aircraft carrier campaigns of the Pacific War.
II. VERTICAL TAKEOFF AND LANDING
Vertical take-off and landing vehicles came into existence due to experiments carried out during the years 1950 –
1970 and almost all came out to be failures. Sometimes it used to have short run before the take-off hence they
were also called STOL, Short run Take Off and Landing vehicle. The flight control and stability of VTOL/STOL
is very difficult and is of prime area of research presently in this field. VTOL emerged gradually over the years and
depicts the current advancement in the field of aerospace. It has basically three configurations up till current
development in this field, wing type configuration, helicopter type configuration and ducted type configuration.
Wing type has fixed wings with vector thrust engine or moving wings with engine, ducted type has ducted rotor
which helps to provide lift, helicopter type has rotor mounted above it to provide lift. Initially the VTOL developed
were of wing type configuration, primarily for military purposes and were man operated but later their importance
was known and more and more advanced designs of it came into existence. The latest ongoing research in this field
is hoverbike which is a hybrid machine. It uses ducted rotors to attain required lift in order achieve its objectives.
It can be either manned or unmanned. Its concept emerged from the Hovercraft which has hybrid capability and
used ducted fan to hover and manoeuvre. Designing with single engine has problems of stability and the design
with multi engine has problem of managing multi engines effectively. The need of the hour is to design a quiet,
low cost, low weight, high power to weight and effective control for VTOL and optimize its performance. However,
there are many innovative solutions in the form of aforementioned hybrid constructions, giving interesting flight
properties. Each type of UAV has its own advantages that predispose it to perform specific tasks. Many UAVs such
as MQ9-Reaper, RQ-2 Pioneer, RQ-5 Hunter, and RQ-4 Global Hawk were designed as fixed-wing type, andtheir
advantage is flight duration and thereby the area of operational activities. Their disadvantage is the need to take-
off and land from the runway, which significantly limits their functionality. Another critical problem associated
with fixed-wing UAVs is that these vehicles are often not appropriate for operating effectivelyin limitedairspace. In
turn, multirotor have the capability of vertical take-off and landing (VTOL), which increases their operational
flexibility. But this construction is unfortunately associated with a high energy demand, which makes the flight
relatively short. A promising trend is development of a vertical take-off and landing (VTOL) fixed-wingplane or
so-called hybrid UAV or VTOL aircraft, which combines the advantages of both designs.
Over the past 53 years, inventors have attempted to create a vehicle that could be flown in the air as well as
driven on land. According to an article in the February 1989 issue of Smithsonian Magazine, more than 30
designs for flying cars have been submitted to the U.S. Patent Office since 1936. These early designs combined
elements of the automobile with those of the airplane. Since the fuselage of the craft was large, usually the size
of a passenger compartment of a car, a huge, powerful engine and large wings were needed to generate enough
thrust and lift to make the craft airborne. On the ground, the huge engine was unnecessary and thus inefficient,
the exposed propeller (if one was used) was a safety hazard, and the large wings had to be removed and stored
prior to driving the craft on the road. The present invention is an aircraft that can be used as a land vehicle
efficiently and without modification. A major difference between the present invention and the prior car/plane

inventions is that the present invention is all one structure so it provides efficiency in the air as well as on the
ground. Ducted fans are used instead of exposed propellers so safety is not compromised. Half of the engines
can be shut down for fuel conservation and efficient operation of the aircraft while being driven on land.
Additionally, the outboard segments of the short wings are hinged to be folded easily, and thus do not have to be
removed from the craft prior to driving. Another feature of the present invention is that it is capable of vertical
take-off and landing (VTOL) by vectoring the fan thrust from the ducted fan engines. Previous VTOL efforts have
relied on fixed orientation of the duct centrelines vertically for hover and then re-directing their thrust with vanes
for transition into forward flight. This method was used with rigid re-directing vanes that would stall the airflow
at angles above 15 degrees. This rigid vane approach resulted in a limited ability to generate a significanttransverse
force for acceleration. The alternative has been VTOL aircraft that have tilted the entire duct or the exposed
propeller, whichever was used, in order to vector the thrust. A tiltable duct or propeller requires complex structural,
electrical and mechanical connections. Furthermore, the tilting duct or propeller experiences off-axis flow into the
inlet during transition into forward flight, resulting in flow separation at the upstream inlet lip. The rotation of the
duct or propeller is inherently slow to react and cannot be modulated to provide the fast response time that is
required for longitudinal control. Additionally, the tilting duct is not an efficient annular aerofoil, and therefore
additional wing area must be provided for aerodynamic lift. This greater wing area resultsin additional drag. After
doing Various studies on the above topics and going through various research papers wefinally understood the
topic and decided to pursue it as it has big potential in future civil and military purposes and can help in
transportation of goods and people going from one place to another.it is also plus point for tourism as well as
aviation industry. Pilots are going to benefit from it for longer period of times as for engineersit will be hands-on
development and design of such an incredible machines which will create a large amount of employment
opportunities in near future which will be a very big boom for economic India.
III. METHODOLOGY
3.1 Topic Selection & Needs
In Aviation Industry, every company or firm needs to design and build a plane which has various advantages
such as high effiency,less fuel consumption, more thrust to carry equipment’s and loads and most important
budget friendly and easy to guiding and handling. So considering all the requirements and data we are trying to
build aircraft which can fit in above mentioned criteria’s.
3.2 Literature Survey
Before starting any project, accurate and reliable information is necessary to get ourselves acquainted with the
topic. Experience also plays an important part while pursuing such topic. In this section, we refer some research
papers, various journals and reference books for proper guidance.
3.3 Designing and Simulation
In this part, we sketch some rough models of our plane to see how the early stage of the plane will look. Based on
the theoretical assumptions and certain assumed data we design our basic 3D CAD model on any modelling
software, by doing this we get a some perception of how the model will look in real world environment. After
that we start to find out the C.G and other different characteristics using XFLR software. Then we perform
simulations on the model using ANSYS or any Simulation software to find out different stresses, aerodynamic
forces, reactions acting on the plane and try to see where the failure will occur in the model. Then we
manufacture a small Prototype of our model using AM.

3.4 Market Survey
After completing design phase we do market survey to find out various components and other electronic parts for
our model. It is necessary step because it helps to estimate the budget of our project, availability of parts and their
cost estimation (BOM).
Parts Procurement and Manufacturing
Once the Market Survey Is done, the next process is the ordering of required parts and to start manufacturing
according to the design.
Assembly and Final Testing
In this Section, We start to manufacture and assemble all the ordered parts according to our design and mathematical
calculations. This process gives birth to our final model.
In order to check whether it works or not, a testing is carried out to see the performance of it and gives a final
Go/No-Go for successful working and testing.Atlast we give a fresh coat of Paint for Aesthetic purpose.

V. CONCLUSION
Air transport is an important enabler to achieving economic growth and development. air transport facilitates
integration into the global economy and provides vital connectivity on a national, regional, and international scale.
it helps generate trade, promote tourism, and create employment opportunities aviation industry known as the
driving force of global technology of development and innovations. Engines and aircraft are become lighter, quieter
and more efficient. emerging technologies are reshaping with robotics, artificial intelligence, the internet of things,
unmanned aircraft systems and the push for hybrid and electric airplanes. HDATV will create new method of
transport of cargo and flying to various different places and cities. it will also be a pilots playground to test the
aircraft and also to increase the hours of plane handling and increasing the experience along with it. The general
public opinion and the view is going to change towards the aviation sector and also adapting the new type of
technology will be breath-taking. the aircraft which we are making can take-off from aircraft carriers and any
stringent locations for covert operations. this helps reduce the risk of compromising missions by safe drop-off to
the battle fronts rather than high altitude parasailing. It also has the also ability to perform various manoeuvres not
possible with a conventional plane; a significant advantage for aircraft in combat situations. by going green it will
also save fuel and also time of travel along with it. our main goal it to make the aircraft efficient, safe and ready
for future tasking and endeavours with ease. Alternative fuels can significantly change the current scenario of
