再入飞行器再入函数及其导数与积分

从“直线弹道”的基本假设和结论出发,推导并给出了再入飞行器再入大气层过程中,诸多物理量的近似解析计算公式,揭示了各物理量之间内在的本质联系、各物理量随再入高度的基本变化规律以及它们与再入飞行器再入初始速度、初始弹道倾角、再入飞行器质阻比的关系。

Reentry Vehicle's Reentry Function and Its Derivate & Integral

Starting from the basic assumption and conclusion of "linear trajectory", calculation formulas of approximate resolution for many physical parameters collected during the process of reentry vehicle's reentry of atmosphere are deduced and given. The interrelationship among physical parameters, the relationship between those parameter values and reentry vehicle's reentry altitudes as well as the relationship between them and initial velocity, initial trajectory angle, and reentry vehicle's mass resistance ratio are also given.
