The innovation of the invention is to provide a proposal for a superacoustic combustion chamber nozzle with a novel structure. The proposal has the characteristic that fuel nozzles are arranged in front of a combustion chamber groove and at the front wall surface of the groove. The design proposal applies the structural design of the groove and the fuel nozzles at the groove in a superacoustic combustion chamber and an improved type superacoustic combustion chamber, and can ensure that fuels are evenly injected in the superacoustic combustion chamber for achieving sufficient mixing, thereby ensuring the ignition and stable combustion of fuels in superacoustic air flow. Compared with the prior nozzle proposal of the superacoustic combustion chamber, the design proposal has the following advantages: the fuels are evenly injected, fully blended, ignited stably and combusted stably, thereby shortening the structural size of the superacoustic combustion chamber, improving the size of the whole superacoustic power system, and having considerable potential economic benefit. The superacoustic combustion chamber nozzle with the novel structure mainly comprises struts in the combustion chamber, the groove and the fuel nozzles in front of the groove and in the groove.
