Autoignition Tests by Injecting Kerosene into Vortex of Decomposed Hydrogen Peroxide

Using decomposed hydrogen peroxide as an oxidizer and kerosene as a fuel, a 1200 N vacuum thrust-class staged-bipropellant engine has been developed and tested with aim to investigate an axial fuel injector integrated a distributor. This fuel injector geometry that injects a fuel into turbulent flow of decomposed hydrogen peroxide was tested to evaluate influence of the designed injector on engine performance. For the characteristics such as autoignition and stable combustion, firing tests over a wide range of equivalence ratio from 0.26 to 1.61 were carried out. Autoignition was achieved in all experimental conditions and pressure variation in the combustion chamber was as low as ± 1%. The efficiency of characteristic velocity, C * , was measured at or over 100% in fuel-lean conditions and from 88% to 94% in fuel-rich conditions at the L * of 0.95 m.
