已经开发了一种计算机代码，用于计算在气动辅助轨道转移飞行器飞行期间预期的低密度状态下非平衡空气的辐射特性。从给定的非平衡热力学状态变量，代码计算的内部状态和伴随的发射和吸收特性的数密度。此外，该代码还计算了处于辐射平衡的假设气体的数密度，该气体产生与给定的非平衡气体相同的辐射发射。示例结果显示，以演示代码如何预测的非线性变化的辐射密度在低密度。
A computer code has been developed that calculates radiative properties of nonequilibrium air in the low-density regimes expected during the flight of aeroassisted, orbital transfer vehicles. From the given nonequilibrium thermodynamic state variables, the code calculates number densities of internal states and the accompanying emission and absorption characteristics. In addition, the code calculates the number density of the hypothetical gas in radiative equilibrium that produces the same radiation emission as the given nonequilibrium gas. Sample results are shown to demonstrate how the code predicts the non-linear variation of radiation with density at low densities.
