Abstract
The paper presents relations for calculation of the thermal loads and trajectory of motion and its optimization during the spacecraft reentry with the second space velocity into the Earth atmosphere. The aerodynamic characteristics of the spacecraft have been determined. Relations for designing and optimization of the weight of a two-layer indestructible thermal shield are given. The trajectory of motion during the aerodynamic maneuver has been generated. The convective and radiative heat fluxes have been calculated. Heat transfer analysis for the model descent trajectory has been carried out. Optimal thicknesses of thermal shields made of different materials have been obtained. The results confirm the principal possibility of creating indestructible thermal shield for the considered class of spacecraft.
期刊介绍:
Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
