Abstract

The invention provides a fuel gas generator. The fuel gas generator sequentially comprises an injector assembly, a combustion chamber assembly and a spraying pipe assembly from top to bottom, the injector assembly is arranged on the head part of the fuel gas generator, the spraying pipe assembly is arranged on the tail part of the fuel gas generator, and the combustion chamber assembly is fixed tothe middle by the injector assembly and the spraying pipe assembly through threaded rods; the combustion chamber assembly includes a protective sleeve, an igniter and a transparent combustion chamber, and the protective sleeve is arranged on the periphery of the transparent combustion chamber; and the protective sleeve is arranged in a spliced mode and includes an upper half segment protective sleeve and a lower half segment protective sleeve. The fuel gas generator mainly aims at gas-liquid injection combustion and can carry out optical measurement in many directions and means.

Description

technical field [0001] The invention belongs to the field of gas generators, and relates to a gas generator. Background technique [0002] Gas-liquid injection combustion is a common combustion mode for gas generators, and has always been the focus of research at home and abroad. How to make gas-liquid fuel mixed and fully combusted is one of the key technologies of the gas generator. In the experiment, only when the combustion process is accurately measured from multiple directions can more credible experimental data be obtained, so it is very important to study it in depth. [0003] Accurately obtaining the performance parameters of small gas generators used in ground tests is of great significance to the study of aerospace propulsion performance. Not only can it save a lot of cost, but it can also reduce risks, improve safety performance, and contribute to laying the foundation for future research. [0004] The traditional measurement method is mostly contact type, tha...
