The summarization of infrared thermography on aerodynamic heating measurement in hypersonic low density wind tunnel
摘要
Abstract
Such problems as surface temperature measurement under great measurement angle,the measurement accuracy,and the corresponding relation between model spatial coordinates and the pixels in infrared thermography etc.,are studied in heating rate measurement by infrared thermography in hypersonic low-density wind tunnel.The studies in the recent years have been summarized and some practical and simple methods are given.To validate these above-mentioned techniques,aerodynamic heating rates on a thin skin flat plate with a wedge were measured by means of both infrared thermography and thermocouple,the ones on a sphere-cylinder model were measured using infrared thermograpy and compared with DMSC theoretical method in hypersonic low density model wind tunnel,and the results agreed well with each other.As a result,the solutions to the problems will push forward infrared thermography to the engineering and practical application.关键词
