提出了一种轻型发动机，能够在从启动到高超音速的大范围马赫数范围内运行，用于飞机和宇宙飞船。提出了一种超级多喷流碰撞压缩系统来代替传统的涡扇压缩系统。用化学反应模型计算流体动力学表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。
A single lightweight engine capable of operating over a wide range of Mach numbers from startup to the hypersonic regime is proposed for aircrafts and spaceships. A compression system of colliding super multijets is proposed instead of a traditional turbofan. 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.
