Description

Project Report CFD Analysis of Aircraft Wing body Abstract This project was aimed at aerodynamic analysis of an aircraft encompassing the various factors involved in flying of an aircraft such as the lift and drag forces acting on the wing and an assessment of the same. Beginning with the wing design and analysis, requirements were first identified and related concepts were formulated. A literature survey was then conducted to establish the focus for analysis. A full scale model of YAK-54 aircraft was chosen and modelled in the designing software package CATIA V5R20. All the analysis part was done in analysis software package ANSYS 13.0. The symmetrical wing section of the YAK-54 with wing profile NACA 23015 was imported in ICEM CFD where a domain was created and the structural meshing of the same was done with finer mesh at critical regions of the wing and then the meshed geometry was imported in analysis software package FLUENT. The aircraft was subjected to high supersonic speed of 450m/s and 900m/s in k-epsilon model and lift and drag forced along with other details were noted down. Velocity and pressure contour and other important parameters such as vorticity, density variations etc. were also plotted. The simulation was performed in steady state conditions. Simulation was also performed in transient state conditions to capture the shock wave at flow velocity greater than Mach 1. The results were in close coherence with actual results. This would help to make any modification required prior to design and manufacture of the aircraft so as to reduce wastages of resources and money. [Department of Mechanical Engineering] Page 1...
