Abstract
The focus of this work is to study the structural response of an aero spiked body in a supersonic flow field of M 2.5 and at zero angle of attack. Fluid-Structure interaction simulations and wind tunnel testing have been carried out on the model for the above condition. 2-way coupled Fluid-Structure Interaction simulations have been carried out to study the aero elastic effect of the aero spike material. The wind tunnel testing for the select condition has been carried out at zero angle of attack for steel spike. The pressure measurement on the flat face cylinder from testing has been compared with that of the simulation data and presented here. Detailed analysis of aero spike deflections, stresses and induced forces due to the shock wave field have been discussed here in detail.
