TI  - VALIDATION OF AERODYNAMIC HEATING PREDICTION TOOL
AB  - Validationof one-dimensional aerodynamic heating and ablation prediction program, AeroheataBSto calculate transient skin temperatures and heat fluxes for high-speed vehicles has been performed. In the tool shock relations, flat plate convective heating expressions, Eckert’s reference temperature method and modified Newtonian flow theory are utilized to compute local heat transfer coefficients. Corresponding governing equations are discretized explicitly and numerically solved. Time varying flight conditions including velocity, altitude and angle of attack serve as input to the program. In order toexamine the accuracy of aerodynamic heating capabilities of AeroheataBS, calculated temperature histories are compared with flight data ofthe X-15 research vehicle, a modified von-Karman nose shaped body, cone-cylinder-flare configuration and results of conjugate computational fluid dynamics studies. Comparative studies show that computed values are in good agreement with the reference data and prove that methodology established in AeroheataBSis appropriate for estimating aerodynamic heating and structural thermal response.
