The combination of kerosene with hydrogen peroxide is more promising due to its low cost, low toxicity, long storage capability, and adequate propulsive performance (Isp>280second, and C*>1400m/s). This research formulates a kerosene based fuel (W2) which shows hypergolic characteristics when in contact with hydrogen peroxide. W2 and hydrogen peroxide present an ignition delay time of 21ms in droplet contact test. The high heating value(ΔH=32.5kJ/g) fuel is prepared by combining several catalysts, promoted mediums, and kerosene to make miscible and hypergolic with hydrogen peroxide. Since the delay time is still long comparing to conventional hypergolic propellant systems, a premixed type bipropellant injector design, namely liquid-cyclonic injector unit has been designed to obtain auto-ignition capability. Liquid fuel and oxidizer are tangentially injected into the small chamber to mix and provide the period for liquid catalytic reaction and the formed hollow center space holds the vaporized propellant to perform gas-phase oxidation reactions to its autoignition temperature. In the hot-fire experiments, the auto-ignition behavor and the operation limits of injectors are also discussed.
