讨论了AJAX概念下碳氢燃料高超声速飞行器大气巡航飞行面临的挑战。特别强调掌握高超声速飞行速度的创新技术，以创造主动热防护和磁塑性机械发动机。热保护不仅确保了建筑的冷却，还确保了含氢混合物的产生，从而改善了燃烧性能。磁流体力学对流动的影响可以增强发动机的比冲，并在非设计飞行条件下创造一个可控的进气口。磁流体发电机在高超声速飞行器上作为动力源的应用也得到了验证。
The challenges of atmospheric cruise flight of a hydrocarbon-fueled hypersonic flight vehicle under the Ajax concept are discussed in this paper. Particular emphasis has been placed on innovative technologies of mastering hypersonic flight velocities that provide for the creation of active thermal protection as well as a magnetoplasmachemical engine. Thermal protection ensures not only cooling of construction, but also production of a hydrogenous mixture, improving combustion behavior. The magnetohydrodynamic effect on the flow makes it possible to enhance the specific impulse of the engine and to create a controllable inlet under an offdesign flight condition. The expediency of magnetohydrodynamic generator application onboard a hypersonic flight vehicle as a power source has also been demonstrated.
