Mesh less Euler Computation for Cropped Delta Wing with Aileron Deflection

The determination of the aerodynamic characteristics of a wing with the control surface deflection is one of the most important and challenging task in aircraft design and development. Many military aircraft uses some form of the delta wing. Euler computation has been done for simulation of transonic flow over a cropped delta wing with the deflected aileron, using in-house developed mesh less solver. Results are presented for the flow past the wing with the aileron deflection =6, and a free-stream Mach number M∞=0.9, at angle of attack =1 and 3. The computed results are compared with available experimental data and Euler computation of finite volume solvers (NAL and Beijing University of Aeronautics and Astronautics, China).
