Abstract

With regard to the safety, economy and miniaturization of the ejector system, a mono-injector air/ethanol gas generator based on the aero-engine combustor structure was designed. A series of ignition tests were carried out. The results show that:the technical design scheme of the gas generator is feasible, and reliable ignition of the gas generator can be realized by direct ignition of the high energy spark plug. The pressure curve indicates a rapid ignition of the generator, and the main working parameters basically meet the design index. The low limit of the excess air coefficient of the gas generator for reliable ignition is 3.9, showing a wide mass flow-rate range. The combustion efficiency is high, decreasing obviously with the increase of the excess air coefficient.
