The Fifth Compression Strategy For Hypersonic Aircar: Proposed By Three Experiments of Shock-Tube, Computation, And Thought

Abstract

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.
