Embodiment Construction

[0063] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0064] A gas deflector based on the principle of film vaporization cooling, such as Figure 1 to Figure 9 As shown, it includes a box enclosed by a panel 1, a bottom plate 2 and four side panels, two transverse partitions 3 and N longitudinal partitions 4 arranged in the box, as well as water supply components, overlapping steel plates 13 and the The mounting seat 5 at the bottom of the body (bottom plate); wherein, said N≥1, the gas deflector is a jacketed structure.

[0065] The four side panels include a first transverse side panel 6, a first longitudinal side panel 7, a second transverse side panel 8 and a second longitudinal side panel 9 connected in sequence; the first longitudinal side panel 7 and the second longitudinal side panel The length of the side plates 9 is 0.5-1.5m, corresponding to the width B of the box, the length L and thickness H ...

Abstract

The invention relates to a gas deflector, in particular to a gas deflector based on the principle of thin-film vaporization cooling and its use method. The high-thrust liquid rocket engine test failed to meet the technical problem of rapid cooling of the diversion groove under the condition of being directly impacted by the engine gas. The deflector includes a box body surrounded by a panel, a bottom plate and four side panels, horizontal and longitudinal partitions arranged in the box, mounting seats, and overlapping steel plates; the transverse partition divides the box interior into multiple separate channels , each transverse partition is provided with a first water hole; N longitudinal partitions located in multiple passages are provided with a second water hole; the middle area of ​​the panel is densely provided with oblique first The water spray holes are evenly provided with the second water spray holes in the areas on both sides; the two ends of the panel are provided with grooves for placing overlapping steel plates. This method is the flow guiding method of the deflector in the test.

Description

technical field [0001] The invention relates to a gas deflector, in particular to a gas deflector based on the principle of film vaporization cooling and a method for using the gas deflector. Background technique [0002] The gas diversion device is used in the test bench of the aerospace engine ground test and the rocket launch pad. When the rocket engine is ignited, the gas diversion device diverts the high-temperature, high-speed gas generated by the rocket engine to keep it away from the direction of the test bench station or the rocket launch platform, so as to protect the safety of the station, platform equipment and measurement and control equipment. "Science News" Volume 528, No. 10, Page 43, "High Temperature Special Cement Builds Rocket Diverter", introduces a gas diversion device (also known as diversion tank) used in rocket launch pads. Corrosion rate refractory concrete poured. Due to the short time (<10s) for the flame to impinge on the gas diversion devic...
