Trainer aircraft wing aerodynamic analysis considering turbulence at operational speed

Author:

Balaji, R. and Dr. Dash, P. K.

Subject Area:

Physical Sciences and Engineering

Abstract:

Light aircraft are being used widely for passenger and freight transport nowadays. In this paper aerodynamics of a trainer aircraft’s 3d wing with NACA 2412 aerofoil is presented. The lift and drag coefficient of the 3d wing at different angle’s of attack using CFD software Fluent is analyzed and the plots of flow parameters like velocity, pressure and path lines are given. In this work kω sst Turbulence model is used to analyze the flow around the 3d wing of the trainer aircraft considering nominal wind turbulence conditions. For this simulation only one wing of aircraft without fuselage is considered taking symmetry in to account. Fuselage is not considered in this work since the objective of this work is to predict the performance of wing alone. Trainer aircrafts operational max speed of 240km/hr is simulated to compute lift and drag coefficients of the wing at different angle of attacks.
