Design Optimization of Inflatable Reentry Vehicle Structure and Thermal Testing Engineering Method
摘要
Abstract
This paper presents a detailed optimization of full deployed radius,half cone angle,the ratio of rigid nose cone radius to full deployed radius by engineering algorithm,and some inflataG ble reentry spacecraft design schemes that satisfying both mass and temperature constraints are obtained.In this paper,the heat flow and temperature variation of the entire reentry process of these optimization schemes are calculated.And through the comparison with the data in the referG ence,the correctness of the engineering algorithm in the paper is verified.According to the calcuG lated heat conditions of the reentry process, different flexible thermal protection system structural test samples are designed refer to the typical thermal protection forms of IRVE in the reference.Finally,the thermal response of each test samples was obtained by thermal shock test, and the thermal insulation performance of each flexible thermal protection system was verified. This paper can provide some reference for the design and improvement direction of flexible therG mal protection in inflatable reentry vehicle.关键词
