Abstract
AbstractThis paper discusses a simplified approach for estimation of skin temperature of aircraft at various flight conditions using computational fluid dynamics to aid precise estimation of cockpit heat load. Major heat load generated inside the cockpit is because of skin friction of air at high speeds. Hence, estimation of the stagnation temperature on aircraft skin is important. Accurate estimation of heat loads will enable the optimum design of air conditioning system with minimal weight and fuel penalty to improve endurance of aircraft. This paper gives a methodology for the calculation of skin temperature by carrying out three-dimensional (3D) modeling of the cockpit in computer aided design software, tetrahedral meshing and simulation in computational fluid dynamics (CFD) design software at various angles of attack (AoA), aircraft speed, and ambient temperatures using CFD software. The solver results are validated by comparing experimental results of Robinson and Hannemann’s standard force referenc...
