在所提出的气动辅助轨道转移飞行器将在高层大气中遇到的非平衡大气化学状态中，空气密度太低，无法保持热和化学平衡，详细的高温空气化学在确定辐射和对流加热负荷方面起着关键作用。虽然振动温度和电子温度仍然很低(小于15000K)，但转动和平移温度可以达到50000 K。目前人们关注的是多个温度对各种化学反应速率常数的影响，对于双分子交换反应和碰撞激发和解离反应都是如此。
In the nonequilibrium atmospheric chemistry regime that will be encountered by the proposed Aeroassisted Orbital Transfer Vehicle in the upper atmosphere, where air density is too low for thermal and chemical equilibrium to be maintained, the detailed high temperature air chemistry plays a critical role in defining radiative and convective heating loads. Although vibrational and electronic temperatures remain low (less than 15,000 K), rotational and translational temperatures may reach 50,000 K. Attention is presently given to the effects of multiple temperatures on the magnitudes of various chemical reaction rate constants, for the cases of both bimolecular exchange reactions and collisional excitation and dissociation reactions.
