Abstract

A new single-point compression principle based on supermulti-jets colliding with pulsation (Naitoh et al, 2010~2015) has a potential for engendering a new single lightweight engine (Fugine) capable of operating over a wide range of Mach numbers from startup to the hypersonic regime with high thermal efficiency due to less heat loss on walls and low noise. Although our previous reports indicate high thermal efficiencies at some Mach number conditions around sound speed, there were very less investigations at very low piston speed below 2,000rpm and at the hypersonic regime. Present computational results show that we can get higher thermal efficiency over 50% even in low piston speeds (about 1,000 rpm) by using the piston movement of a sigmoid manner. At the hypersonic regime, we demonstrate the results of higher power for conditions closer to the stoichiometric condition.
