Abstract:

The ELAC 1 (ELliptical Aerodynamic Configuration 1) is basically Hypersonic space vehicle and first stage of TSTO (Two Stage To Orbit) destined to fly up to altitude of 35 Km with M_∞=7 (Free stream Mach No.). In this paper, the comparison between the experimental data available at RWTH, Aachen and Polyhedral Unstructured Navier-Stokes solver simulations are made. The different AOA (Angles of attack) 0̊, 6̊ and 10̊ are considered with R_e = 3.6×10⁶ for the supersonic flow simulations. The various coefficients such as Aerodynamic coefficients, Pressure coefficients are compared with the wind tunnel data and the physics of the flow field is investigated.
