Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] The invention provides a small gas injection optically transparent combustion device, such as figure 1 As shown, the device includes a combustor head cavity 1 , a transparent combustor 2 and a combustor tail 3 . The combustion chamber head chamber 1 and the combustion chamber tail portion 3 fix the transparent combustion chamber 2 in the middle through four uniformly distributed screw rods 402 . The two ends of the screw 402 are respectively connected with four hexagonal nuts A401 and four hexagonal nuts C404 to exert a pre-tightening force on the transparent combustion chamber 2 between the combustion chamber head cavity 1 and the combustion chamber tail 3 to reach the transparent combustion chamber 2. sealing requirements. Considering that the test device is in a vertical state during actual use, and the transparent combustion chamber 2 is in dange...

Abstract

The invention discloses a small gas-gas injection optical transparent combustion device and suitable for the field of multi-optical diagnosis technology. The combustion device comprises a combustion chamber head cavity, a transparent combustion chamber and a combustion chamber tail. The transparent combustion chamber is fixed between the combustion chamber head cavity and the combustion chamber tail by four uniformly distributed screws. Two ends of each of the screws are cooperatively connected with one hexagonal nut A and one hexagonal nut C so as to impose pretightening force on the transparent combustion chamber, thereby achieving sealing requirements in the transparent combustion chamber. Hexagonal nuts B are cooperatively connected to the screws under a combustion chamber pressing cover and are used for supporting the combustion chamber pressing cover. The transparent combustion device performs comprehensive detection for combustion states, and helps people to deep research combustion mechanism. According to the similarity principle of combustion, research principles of combustion mechanism in a low pressure environment are established, so combustion condition in a high pressure condition can be predicted.

Description

technical field [0001] The present invention relates to a gas injection combustion device suitable for multi-optical diagnosis, more particularly, a transparent combustion device suitable for multi-optical diagnosis of rocket engines with low thrust, low flow rate and low combustion chamber pressure . Background technique [0002] The full-flow afterburning cycle engine is a new circulation mode of the liquid rocket engine, and the gas-gas injector combustion technology is one of its core technologies. During the test, the combustion process needs to be measured accurately in multiple directions in order to obtain accurate and credible performance parameters, which facilitates more research on the nature of its combustion mechanism. [0003] The traditional combustion measurement device is a contact measurement method. Generally, the sensor probe is arranged in the area to be measured or in the flow field. After reaching equilibrium after a certain period of time, the param...
