Abstract

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.
