Fatigue life estimation of rear fuselage structure of an aircrafteSAT Journals
This document summarizes a study on estimating the fatigue life of the rear fuselage structure of an aircraft. The researchers created a finite element model of the rear fuselage structure in CATIA and analyzed it in MSC.PATRAN and MSC.NASTRAN to identify high stress regions. They found the maximum stress locations were at cut-out corners and rivet holes in the skin. A local model with finer meshing around the cargo door cut-out was also analyzed. Fatigue life was then estimated using Miner's rule and an S-N curve, accounting for factors like surface roughness and reliability. Damage was accumulated over the expected load cycles to predict fatigue life until crack initiation.

Stress and fatigue analysis of landing gear axle of a trainer aircrafteSAT Journals
Abstract The undercarriage or landing gear of an aircraft is the structure that supports an aircraft on the ground and allows it to taxi, takeoff and land. Among the various parts of landing gear, axle is the most critical component where the loads (landing and ground loads) act on the axle first, then transferred to the structure. In this study stress and fatigue analysis of the axle is performed to meet the strength and life requirements. The modeling of the axle is done using UniGraphics (UG) software. Stress analysis is carried out using MSC Patran (pre-processing and post-processing)/Nastran (solver) for different landing loads (spin up, spring back, maximum vertical and drift) and ground handling loads (braking, taxing and turning). Stress analysis was carried out by both classical and FEM approaches and by comparing the results it was obvious that they were in correlation with one another. Fatigue analysis was also carried out for the axle using landing spectrum and ground handling spectrum to estimate the fatigue life. By the iteration process, the requirement of 10000 landings was satisfied. Keywords: Static, Fatigue, Axle, Fatigue life, UniGraphics, MSC Patran, MSC Nastran

Fatigue fracture of a main landing gear swinging leverin a civil aircraftPramodKawade
The left main landing gear of an aircraft collapsed during takeoff due to fatigue fracture of the swinging lever after 26,139 flights. Fractography analysis revealed the fracture initiated from the surface of the lever near the most stressed region as identified by FEA stress analysis. Microstructural examination found an abnormal amount of silicon at the origin site which led to stress concentrations. AFGROW fatigue analysis using the FEA stress data predicted a fatigue life of 20,000 cycles, consistent with the actual life, indicating the failure occurred due to exceeding the fatigue life of the lever.
Stringers are longitudinal stiffening members that support aircraft skin and prevent buckling. They transfer loads between the skin and supporting structures like frames and ribs.

VORTEX DYNAMIC INVESTIGATION OF WING SLOTTED GAP OF SAAB JAS GRIPEN C-LIKE FI...IAEME Publication
Canard fighters generally configured with wing canard-deltas and would generate
an airflow phenomenon producing vortex cores and lifts. The lift distribution would
stall at a high angle of attack (AoA). This study investigated the vortex dynamic of
wing canard delta configurations of the Saab JAS Gripen C-like model which create
different wing planform than other fighters. The slotted leading edge of the Gripen
would develop a strong vortex core on the outer wing, on the same direction with the
spin of wing vortex; the outer core would drag the inner vortex core and strengthened.
Consequently, the vortex core streamlined in a leading edge of the wing would begin
to detach, resulting rolled-up vortices in the wing leading edge followed by a solid
laminar stream which tends to curl out. The trailing edge of the wing tended to
laminarize backward. The result would be a negative surface pressure on the leading
edge above the canard and on the wing which causes more negative surface pressures.
An increase in AoA will generate a closer vortex breakdown location to the wing
leading edge. The location was calculated as the ratio of the axial velocity
Comparison of the lateral deflection at midpoint of long & short side columnIAEME Publication
This document summarizes a study that used finite element analysis to compare the lateral deflection of long and short side reinforced concrete columns subjected to blast loading.

It found that the long side columns experienced significantly higher maximum lateral deformations than the short side columns. Ratios of short to long side column deformation ranged from 0.24 to 0.38 depending on the column. The study concluded that column length and orientation affects deformation under blast loading, with long side columns experiencing greater impacts.

Abstract This Innovated model of Darrieus Straight bladed Vertical Axis Wind Turbine system is the construction of a Three-bladed rotor system with each modified turbine blades suited to withstand on different circumstances. The modified blades are thus adjusted in a manner of the air flow striking close enough on the rotor. This paper presents a mean for reducing the loss of air flow during the process of a vertical-axis wind turbine (VAWT) by modifying each blade. The model was designed in such a way that one part of the turbine has an additional semicircular plate attached on the direction of wind, while the second rotor has a alteration in this design with air deviating wing which proves to be efficient. This modification results in the maintaining the lift and drag force on wind-blades. The generator can be driven by this modified Darrieus SBVAWT system to produce electricity, especially for agricultural purposes. For this purpose, three dimensional CFD analyses have been performed on a straight-bladed Darrieus-type rotor. The Darrieus rotors have been designed using CATIA and the model was tested for computing mesh by CFD software for finding the various factor of the VAWT system. The performance was analyzed and a result of the Darrieus rotor was obtained, which shows that this model can purely withstand. The changes made in the design of the turbine blades have proved to be efficient. Keywords: VAWT, Straight blade, Air foil, Power coefficient.

Design optimization of excavator bucket using Finite Element MethodIjripublishers Ijri
An excavator is a typical hydraulic heavy-duty human-operated machine used in general versatile construction operations,
such as digging, ground leveling, carrying loads, dumping loads and straight traction. Normally backhoe excavators
are working under worst working conditions. Due to severe working conditions, excavator parts are subjected to
high loads and must work reliably under unpredictable working conditions. Thus, it is necessary for the designers to
provide not only an equipment of maximum reliability but also of minimum weight and cost, keeping design safe under
all loading conditions.

Analysis of s s short cylindrical shells under internal hydrostatic pressure ...eSAT Journals
Abstract A new approach to the analysis of S-S short cylindrical shells subject to internal hydrostatic pressure is presented. Short cylindrical shells with both ends simply supported (S-S) loaded with axisymmetric internal hydrostatic pressure was considered. By satisfying the boundary conditions of S-S short cylindrical shell in the general polynomial series shape function, a particular shape function for the shell was obtained. This shape function was substituted into the total potential energy functional of conservation of work principle, and by minimizing the functional; the unknown coefficient of the particular polynomial shape function was obtained. Bending moments, shear forces and deflections of the shell were determined, and used in plotting graphs for a range of aspect ratios, 1 ≤ L/r ≤ 4. Stresses and deflections at various points of the shell were determined for different cases. Considering case one, with aspect ratio 1, maximum values of deflection, rotation, bending moment and shear force were m, -3.29878radians,KNm and KN respectively. Thus we observed that the stresses and strains along the S-S short cylindrical reservoir vary inversely as the aspect ratio. Key Words: Analysis, Boundary condition, Conservation of work principle, Hydrostatic pressure, Polynomial series, Shape function, Short cylindrical shell.

This study analyzed the behavior of an outrigger structural system on a 40-story steel structure by varying the depth of the outriggers. Three models were analyzed: with outrigger depth equal to full story height, 2/3 of story height, and 1/3 of story height. Lateral displacement and story drift were compared between a structure with a central braced core and each outrigger model. Results showed that providing additional outriggers and belt trusses reduced displacement and drift by up to 36.96% and 30.10% respectively. Reducing outrigger depth to 2/3 and 1/3 of story height resulted in only minor increases in displacement and drift compared to full height outriggers. The

Consequently, the vortex core streamlined in a leading edge of the wing would begin

An increase in AoA will generate a closer vortex breakdown location to the wing

Stresses and deflections at various points of the shell were determined for different cases. Considering case one, with aspect ratio 1, maximum values of deflection, rotation, bending moment and shear force were m, -3.29878radians,KNm and KN respectively. Thus we observed that the stresses and strains along the S-S short cylindrical reservoir vary inversely as the aspect ratio. Key Words: Analysis, Boundary condition, Conservation of work principle, Hydrostatic pressure, Polynomial series, Shape function, Short cylindrical shell.

This study analyzed the behavior of an outrigger structural system on a 40-story steel structure by varying the depth of the outriggers. Three models were analyzed: with outrigger depth equal to full story height, 2/3 of story height, and 1/3 of story height. Lateral displacement and story drift were compared between a structure with a central braced core and each outrigger model. Results showed that providing additional outriggers and belt trusses reduced displacement and drift by up to 36.96% and 30.10% respectively. Reducing outrigger depth to 2/3 and 1/3 of story height resulted in only minor increases in displacement and drift compared to full height outriggers. The

This paper presents a novel six degrees of freedom mechanism to integrate conical article with the cylindrical article which are large and heavy. The six desired motions include six linear motions and six rational motions. The linear motions are vertical, longitudinal and lateral. The vertical motion is achieved by toggle jack, longitudinal by wheel and rail assembly and the lateral motion is achieved by cross slides. The three rotational motions namely pitch, yaw and roll are achieved by simultaneous movement of toggle jacks, simultaneous movement of cross slides and rollers respectively. It is designed in such a way that it sustains the weight of the heavy articles and also prevents slipping and toppling of the conical article. This approach helps to satisfy and fulfil the goal of aligning the main article flange to the conical article flange for further bolting. The mechanism is designed keeping in mind factors like ergonomics and aesthetics.

Optimizationof fuselage shape for better pressurization and drag reductioneSAT Journals
Abstract
The fuselage of any aircraft is essentially to accommodate the payload. It is normally not as streamlined as the wing. Cabin pressurization has been a major concern in the manufacturing of aircrafts. Generally, a cylindrical shape is preferred from a pressurization point of view as it has a higher strength and weighs less too. On the other hand, a sphere is considered as the best pressure vessel among all the shapes, but, sphere being a bluff body is not suitable for carrying payloads. On this note, a cylinder is considered to be better than a sphere to carry the payload and mainly to achieve a streamlined flow. In this paper, the shape chosen is a combination of the sphere and the cylinder to achieve optimum results for pressurization as well as a better streamlined flow. Our prime aim is to convert this bluff body into something more efficient and useful, rather than only for carrying the payload. We have focused basically on two details viz. 1) Better Pressurization and 2) to assist in minimizing the drag, thereby increasing the overall lift of the aircraft and hence increasing the fuel efficiency. The proposed fuselage structure was designed in CATIA V5 software and structural analyses were done in Auto-Desk Multi-Physics software. As a result, a better structural load capacity was found. A load of 10 N/mm2 was applied on both the bodies under consideration (cylinder and ellipse) having the same material, surface area, volume and weight. For the proposed elliptical design, 78% reduction in the minimum stress value and 10% reduction in the maximum stress value were noticed.

Stability Control Structure of Hovercraft Prototype Utilising PID ControllerjournalBEEI
Hovercraft is a method of transportation as an option for clients who remain on the waterway and swamp surface. The issue with hovercraft is when dubious climate and natural condition, e.g. wind speed and wave tallness exasperate solidness of hovercraft to jeopardise the driver. We propose an approach to keep up adjust of the hovercraft by controlling the focal point of gravity (PG) to be determined position. The controller monitors the position of load to change the position. A 6-DOF IMU Sensor MPU 6050 was utilised to create information as an examination with setpoint. PID control strategy was employed. The test outcome demonstrates that the model of air cushion vehicle could keep its adjust the axis orientation of the roll in spite of the fact that it was less compelling in the pitch pivot direction.

DESIGN AND ANALYSIS OF AN ACTIVE TWIST ROTOR BLADES WITH D-SPAR MODEL USING C...AM Publications
Today’s helicopters are the result of collaborative work in mechanical engineering and aeronautics. A helicopter main rotor or rotor system is the combination of a rotary wing and a control system that generates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic drag in forward flight. In the field of rotorcraft, the research in this project is currently focusing on active blade systems to adapt the aerodynamic properties of the blade to the local aerodynamic conditions. Fuel-efficiency, reduction of vibration and noise and increase of the helicopter maximum speed are the benefits expected from these new technologies. A helicopter's rotor is generally made of two or more rotor blades. Rotor blades are made out of various materials, including aluminum, composite structure, and steel or titanium, with abrasion shields along the leading edge. The blade pitch is typically controlled by a swash plate connected to the helicopter flight controls. An Active Twist Rotor (ATR) is developed for future implementation of the individual blade control for vibration and noise reduction in helicopters. The rotor blade is integrally twisted by direct strain actuation using active fiber composites (AFC). In this thesis, the model of rotor blade is designed and analyzed. 3D models are done in CATIA. Analysis is done in Ansys. The materials used for original model are steel and Aluminum alloy, The modified model is analyzed by specifying aluminum alloy using solid element and also the shell element. The optimization results have been obtained for design solutions, connected with the application of active materials.

Design and Fatigue Analysis of a Typical Aircraft Wing fuselage Lug attachmen...SonuKumar1049
- The structure of a fighter jet is quite complicated. The aeroplane is required to do challenging
manoeuvres while fighting off enemies. During that, high magnitude stresses will be placed on the wings as a result
of the combination of high level acceleration and challenging maneuvers. The fighter aircraft often has multiple wing-fuselage attachment points. An aircraft
rarely has a static overload-related failure during its service life. Fatigue and damage tolerance design, analysis, testing, and service experience correlation are
crucial for maintaining an aircraft's airworthiness during
its entire economic service life. The fatigue loading that
occurs during service on lug-type joints completes load
transmission through the pin. This is why the wing-fuselage lug joints are regarded as the aircraft structure's most fracture-critical parts.In the current project, an attempt is made to
predict the fatigue life of a wing-fuselage attachment
bracket of a fighter aircraft to meet the stress and fatigue
design considerations. Subsequently, linear static analysis
is carried out. The stress results of finite element analysis
show that stress levels of lug structure meet the strength
requirement. Furthermore, utilizing constant amplitude SN data for various stress ratios and local stress history at
stress concentration, fatigue life computation is carried for a typical service loading. The lug structure's computed damage factor for the given load spectrum comes out to be less than one. This demonstrates that the wing lug structure is safe to use and that the crack has not initiated

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

EXPERIMENTAL STUDY OF MECHANICAL AND TRIBOLOGICAL RELATION OF NYLON/BaSO4 POL...IAEME Publication
An experiment conducted in this study found that BaSO4 changed Nylon 6's mechanical properties. By changing the weight ratios, BaSO4 was used to make Nylon 6. This Researcher looked into how hard Nylon-6/BaSO4 composites are and how well they wear. Experiments were done based on Taguchi design L9. Nylon-6/BaSO4 composites can be tested for their hardness number using a Rockwell hardness testing apparatus. On Nylon/BaSO4, the wear behavior was measured by a wear monitor, pinon-disc friction by varying reinforcement, sliding speed, and sliding distance, and the microstructure of the crack surfaces was observed by SEM. This study provides significant contributions to ultimate strength by increasing BaSO4 content up to 16% in the composites, and sliding speed contributes 72.45% to the wear rate
ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.
