Problems solved by technology

[0003] The thermal insulation function of the climate environment laboratory is mainly realized by the thermal insulation of the inner wall panels, floors and ceiling panels of the laboratory. Great changes occur in a short period of time, and the pressure-bearing and shock-proof capabilities of the laboratory insulation wall panels are limited, which will damage the inner wall structure of the climate environment laboratory and easily cause the insulation structure of the internal wall panels of the climate environment laboratory to fail. , reduce the thermal insulation function of the inner wall of the climate environment laboratory

Embodiment 1

[0056] like figure 2 As shown in the figure, an antifreeze pressure regulation system for aircraft testing includes a thermal insulation regulation channel 1 arranged between the laboratory outer wall panel and the inner thermal insulation storage board, and a thermal insulation regulation channel 1 arranged at the connection between the thermal insulation regulation channel 1 and the internal thermal insulation storage board. An anti-freezing pressure regulating device 2, and an anti-freezing shutter device 3 arranged at the connection between the thermal insulation regulating channel 1 and the outer wall panel of the laboratory;

[0057] like figure 2 As shown, the heat preservation adjustment channel 1 includes a first heat preservation channel 10 connected to the laboratory outer wall panel at one end and the inner heat preservation library plate at the other end, and a second heat preservation channel 11 arranged inside the first heat preservation channel 10; The centr...

Embodiment 2

[0077] The difference from Example 1 is:

[0078] like Figure 8 As shown, the support and limit frame 202 is provided with a duct blocking mechanism 22 connected with the air outlet regulating duct 210;

[0079] The duct blocking mechanism 22 includes sliding guide rails 220 fixed on the support limiter 202 and located above and below the air outlet regulating duct 210 . The sealing plate 221 , the fixing members 222 arranged on both sides of the sliding guide 220 , and the telescopic assembly 223 , one end of which is arranged on the sealing plate 221 and the other end is arranged on the fixing member 222 .

Embodiment 3

[0081] The difference from Example 2 is:

[0082] like Figure 9 As shown, the antifreeze shutter device 3 includes a first rectangular frame 30 arranged on the outer wall panel of the laboratory, and a second rectangular frame 31 arranged in the center of the first rectangular frame 30 for connecting the first rectangular frame The frame 30 and the frame fixing member 32 of the second rectangular frame 31, the first shutter assembly 33 disposed between the first rectangular frame 30 and the second rectangular frame 31 and communicating with the first heat preservation channel 10, and the A second shutter assembly 34 inside the second rectangular frame 31 and communicating with the second heat preservation channel 11 .

[0083]The lower end of the blade of the first shutter assembly 33 is close to the outside of the laboratory outer wall panel; the lower end of the blade of the second shutter assembly 34 is close to the inner side of the laboratory outer wall panel.

Abstract

The invention relates to the technical field of aircraft testing, and discloses an anti-freezing pressure adjustment system for aircraft testing and an adjustment method thereof. An antifreeze pressure regulating device at the connection between the regulating channel and the inner thermal insulation storage board, and an antifreezing shutter device arranged at the joint between the thermal insulation regulating channel and the laboratory outer wall panel; the thermal insulation regulating channel includes one end connected to the laboratory outer wall panel, The other end is connected to the first heat preservation channel of the inner heat preservation storage board, and the second heat preservation channel arranged inside the first heat preservation channel; the central axis of the first heat preservation channel and the second heat preservation channel coincide; The pressure in the tested climate environment laboratory is adjusted to protect the inner insulation board and avoid functional damage to the structure of the inner insulation board due to pressure difference.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to an antifreeze pressure regulating system for aircraft testing and a regulating method thereof. Background technique [0002] In the field of aircraft testing technology, the climate environment laboratory, as a large-scale carrying facility for various types of aircraft tests, must accommodate full-size aircraft and provide all-weather, time-limited high temperature, low temperature and other environmental conditions, which requires the climate environment laboratory Has the most basic heat preservation function. [0003] The thermal insulation function of the climate environment laboratory is mainly realized by the thermal insulation of the inner wall panels, floors and ceiling panels of the laboratory. All the surrounding areas of the laboratory are composed of standard-sized thermal insulation panels; during some tests, the laboratory pressure will be Great changes o...
