Aerothermodynamic Design and Optimisation of Hypersonic Research Reentry Vehicle

Manjunatha H | C. N. Nataraj


Abstract: Among variety of design requirements reducing the aero heating problem is most crucial one. The hypersonic vehicle flying at hypersonic speed generates strong bow shock ahead of nose which is responsible for aero heating problem; the problem can be analyzed in two ways without spike and with spike. This investigation considers the mach 9.0 with analyzing the temperature, pressure, heat flux, and heat transfer co efficient over the body surface with two different predefined pressure conditions i. e.50 and 100 bar for without spike and with spike. Spike design replaces strong shock instead of weaker shocks at the nose and weaker shocks reduce the temperature at the vehicle. It is found that with spike yields better results than without spike vehicle. with different predefined pressure conditions. Model created in solid works, and meshing in Gambit 2.4.6 finally solution is by Fluent 6.3 solver.
