Abstract

A new type of single engine capable of operating over a wide range of Mach numbers from subsonic to hypersonic regimes is proposed for airplanes. Traditional piston engines, turbojet engines, and scram engines work only under a narrower range of operating conditions. The new engine has no compressors or turbines such as those used in conventional turbojet engines. A notable feature is its system of super multijets that collide to compress gas for the transonic regime. A numerical model simulating compressible turbulence with chemical reactions based on the CIP and BI-SCALES methods is employed to design the engine. The maximum power of this engine will be sufficient for actual use. For the higher Mach numbers in supersonic and hypersonic conditions, this engine can take the mode of a ram or scramjet engine.
