Introducing the FACL algorithm and numerical temperature simulator to stress analysis of aerospace structures

Abstract
Because of irrational behavior of the load contours applied to aerospace structures, mapping the output contours of fluid software at text file as input file for structural software with respect to requirements of it is most accurate method to analysis and design of aerospace structures. The most applicable of design's software of those, are Fluent and Abacus, therefor in this research, the FACL algorithm, to create of the comprehensive input file of Abacus, is introduced by mapping of the output contours of fluent software. Induced aerodynamic -heating on the surface of the supersonic and hypersonic vehicles is one of the principal parameters of their design in aerodynamic, structural, and other terms, and Because of the deviation of it and surface temperature with empirical results due to steady state of solution and unspooling of shock layer chemical reactions at Fluent software, the temperature result files of CTCA software which written by these researchers is combined with the aerodynamic pressure results of Fluent during the flight trajectory, and the input file to structural automotive analysis by Abacus is created. Designing the attachment structure of ceramic ray dome of the vehicles which equipped to a radar seeker, using the FACL algorithm is essential. The flight test results of a typical vehicle equipped to ceramic ray dome and the structural analysis results of a controller wing of a typical vehicle show, to design and structural analysis of aerospace structures during flight trajectory, the FACL algorithm results is very accurate in comparison of other methods.
