在我们之前的报告和专利中，提出了一种轻型发动机，能够在从启动到高超音速的广泛马赫数范围内运行，用于飞机，飞机和宇宙飞船。为此，提出了一种新型的超多射流脉动碰撞压缩系统。这种新型压缩系统与传统的活塞式、涡扇式、瞬时失稳式和脉冲爆震式四种发动机的压缩系统有本质上的不同。这是第五个压缩原理。激波管实验和具有化学反应模型的计算流体动力学证明了该体系的巨大潜力和稳定性。这种终极发动机系统可以通过特殊的活塞和冲压式喷射系统进行扩展，以在地面和空间之间的各种情况下实现更高的燃油消耗率，同时保持非常低的噪音水平和无声爆炸。目前的发动机系统也将解决高声速条件下的嗡嗡声问题。
In our previous reports and patents, a single lightweight engine capable of operating over a wide range of Mach numbers from startup to the hypersonic regime was proposed for aircars, aircrafts, and spaceships. A new compression system of colliding super multijets with pulsation was proposed for this purpose. The new compression system essentially differs from those for the traditional four types of engines with piston, turbofan, ran-scram, and pulse-detonation. This is the fifth compression principle. Shocktube experiments and computational fluid dynamics with a chemical reaction model clarifies a large potential and stability of this system. This ultimate engine system can be extended with a special piston and scram jet systems to achieve an improved fuel consumption rate at various situations between the ground and the space, while maintaining a very low noise level with silent detonation. The present engine system will also solve the problem of the buzz at highersonic conditions.
