N2 - Shock tube experiments reveal whether or not the single lightweight compression system of the supermultijets colliding with pulsation for aircars and aircraftsworks stably, which was proposed based on our previous three-dimensional unsteady computations. This compression system essentially differs from those in the traditional four types of engines with piston, turbofan, ran-scram, and pulse-detonation, because of the supermulti-jets colliding. The single compression system is capable of operating over a wide range of Mach numbers from startup to the hypersonic regime. Shocktube experiments clarify the stability range of this system in detail. Influence of the number of supermulti-jets on the stability will also be examined. This system can also 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 low noise level and also solving the problem of the buzz at highersonic conditions.
