Embodiment Construction

[0053] In order to make the solution of the present invention more clear, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0054] A high-frequency longitudinal combustion chamber suitable for impingement injectors, including a supply line 1 for delivering oxidant and fuel, a head adapter section 2, an independent injector 5, a combustion chamber barrel 4 and a replaceable Water-cooled throat7.

[0055] The supply pipeline 1 includes a fuel supply pipeline and an oxidizer supply pipeline. The supply pipeline 1 is connected to the front end of the head adapter section 2, and the oxidant and fuel are delivered to the independent injector through the head adapter section 2. 5, the oxidant and fuel enter the combustion chamber cylinder 4 through the independent injector 5, and the fuel and the oxidant cooperate with each other to burn in the combustion chamber cylinder 4.

[0056] A bracket 3 is provide...

Abstract

The invention particularly relates to a high-frequency longitudinal combustion chamber suitable for an impact type injector. The high-frequency longitudinal combustion chamber is used for solving the problem that excitation of high-frequency longitudinal combustion in a combustion chamber is unstable. The device comprises a head switching section, an independent injector, a combustion chamber barrel and a water-cooling throat part, the rear surface of the head adapter section is connected with one end of the combustion chamber barrel; the front surface of the head switching section is connected with a supply pipeline, an independent injector is arranged between the head switching section and the combustion chamber barrel, and the front surface of the independent injector is connected with the rear surface of the head switching section; and the other end of the combustion chamber barrel is connected with a water cooling throat part. According to the combustion chamber suitable for the impact type injector, the phenomenon of unstable longitudinal combustion can be reliably excited.

Description

technical field [0001] The invention relates to a stability test device, in particular to a high-frequency longitudinal combustion chamber suitable for an impact injector. Background technique [0002] The combustion instability of liquid rocket engines seriously threatens its reliability. It is usually necessary to assess the overall stability of different injector structures. For this reason, it is necessary to stimulate high-frequency longitudinal combustion instability without changing the injector and combustion chamber structures. The phenomenon is used to compare the stability of different injection schemes laterally. [0003] In order to achieve the above goals, the following aspects need to be considered: [0004] 1) The combustion chamber needs to be designed to be modular to facilitate the adjustment of the natural acoustic frequency; [0005] 2) The injector needs to be designed as an independent and replaceable structure, which is convenient for carrying out h...
