Every country is aiming to develop its power over all the aspects that considered for comparison with other countries in order to stand at same level of competition with others. One such power considered by all countries to develop every possible way to have a healthy competition is the military power which involves basically innovations of fast moving aircraft having a high lift coefficient and low drag coefficient. Such an aircraft having the high lift and low drag coefficient is TEJAS (HAL) developed by country India on which the purpose of paper mainly sustains. The paper mainly focuses on steady-state flow analysis over aircraft TEJAS using the computer aided modelling techniques and also the comparison of the results obtained from the modelled techniques. The paper also outlines the designing of the structural model of the TEJAS in a modelling software, creation of a finite computational domain, segmentation of this domain into discrete intervals, applying boundary conditions such as velocity in order to obtain plots and desired results determining the coefficient of pressure, lift and drag coefficient, velocity magnitude etc. This paper also aims in creating awareness to the future students about the techniques involved and knowledge required for developing a designed modelled. This paper also highlights the use of CFD techniques involved for the purpose of fluid flow simulation of the aircraft especially performing the meshing techniques, pre and post processing techniques and finally the evaluation of the simulation.

Design and Fabrication of Blended Wing Bodyvivatechijri
Aircrafts are the widely used vehicle for rapid and long distance transportation. Although it is time
consuming, the conventional design of aircraft doesn't gives much space inside the aircraft and also consumes
more power because of its aerodynamic structure. Hence it is necessary to develop a new composite structural
design which overcomes these barriers. Blended Wing Body (BWB) is one of the solution of these problems. The
BWB configuration is a new concept in a aircraft design which provides greater internal volume, aerodynamics
and structural efficiency & noise reduction. The design approach of BWB is to maximize overall efficiency by
integrating the propulsion system, wings and the body into a single lifting surface. BWB is a unibody air craft
where the fuselage, wing and tail gets merged to form a single entity. The fuselage section of BWB is flattened
and has slightly airfoil shaped structure which exceeds the overall lift generation of aircraft. The objective of this
paper is to study aerodynamic study of Blended Wing Body. The project deals with the designing, analysing and
fabricating of UAV(Unmanned Aerial Vehicle) type electrically powered BWB aircraft system, and also selecting
appropriate propulsion system and other electric components

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Abstract.
The objective of this paper is to produce and assess a conceptual design study for a future large
transport aircraft using the supercritical SC (2)-0412 wing, produced using advanced composite
manufacturing processes namely the PRSEUS process and compare this to reference composite
airframe based on both Airbus A350XWB and Boeing 787 composite airframe technology. This is to
assess the possible benefits of using PRSEUS on a conventional wing and tube aircraft configuration
in a pressurised environment i.e. fuselage and wing fuel tanks, as a prelude to its adoption for
advanced concept wing / tube and BWB aircraft. This project will also study the automated assembly
of the wing structure using kinematic simulation tools. The result will be to establish the advantages
and limitations of readily available structural design, process simulation, kinematic and structural
analysis toolsets, namely Catia V5.R20 and NASTRAN / PATRAN 2000, the source for configuration
and loading being AeroDYNAMIC V2.08 and JET Designer 3 in developing an innovative
manufacturing and assembly concept in a virtual environment.
PRSEUS or Pultruded Rod Stitched Efficient Unitized Structure is one of many, possible architectures
which are classed under the more generic category of Stitched Resin Infusion (S/RI). The major
benefits of stitched composites are as follows: - damage arresting: enable thickness gradients: build
one-piece larger structures-combined frame, skin and stringer: more efficient load paths hence lighter
structure: reduces fasteners, and facilitates bolted repair of damage: externally bagged structure-soft
tooling-no inter-modeline tooling: and resin infusion with oven curing at one atmosphere so does not
require an autoclave.
Currently stitched resin infused composite structures include all eight moderately loaded landing gear
door structures on the Boeing C-17 military transport circa 2007: the lightly loaded LAIRCM system
fairing also on the C-17 circa 2003 , and NASA test wing box of the 1990’s, and flat panel test articles
to support the NASA BWB program. Therefore there is a need assess this technology in a highly
loaded more complex structure to fully assess the benefits and limitations of this technology.
This conceptual design study is only a starting point to much more ambitious funded research, and is a
conventional twin engine 250-300 seat class point to point aircraft design. The study consists of two
phases, the first of which was overall airframe configuration design and parametric analysis using both
classical analysis and the Jet306 / AeroDYNAMIC V2.08 analysis tool set, and the second was major
structural airframe component layout of the airframe initial structure with systems integration using
hand calculations with Catia V5 FEA modelling for structural sizing. This final design study for both
versions of the airframe reference and new build contained herein consists of parametric analysis,
initial optimisation and structural layout and constitutes a feasibility study proposal to determine the
benefits. Recommended further work on the proposed design includes CFD aerodynamic analysis, and
more rigorous FEA analysis using more accurately defined aero and structural loads.
