Problems solved by technology

The useful electrical port is set in the laboratory to meet the electrical demand of special ring molds, digital acquisition systems, test pieces and other facilities. When the cable passes through the insulation wall, the hole is not well sealed, which will lead to condensation, icing or increased fresh air flow at the interface, which will affect the laboratory and test, and the serious result will lead to short circuit damage to the test piece Wait, cause a major accident

Embodiment 1

[0042] Such as figure 2 , 3 A communication maintenance system for aircraft testing is shown, including a maintenance kit and a sealed and heat-insulated assembly for sealing and insulating the maintenance kit; the maintenance kit includes a sleeve assembly 1 that can pass through the environmental bulkhead, and can be installed in the An outer end plate assembly 2 on the outer wall of the bulkhead plate and capable of being connected to one end of the sleeve assembly 1, and an inner end plate assembly 3 capable of being installed on the inner wall of the environmental bulkhead plate and capable of being connected to the other end of the sleeve assembly 1; the sleeve assembly 1 includes a sleeve body 11, a telescopic sleeve 12 movably installed inside the sleeve body 11, and a protective sleeve 13 for protecting cables;

[0043] Such as figure 2 As shown, the sleeve body 11 includes a tube body 111 and a ring 112 arranged at both ends of the tube body 111; the ring 112 is ...

Embodiment 2

[0065] The difference from Embodiment 1 is that the cross sections of the outer end plate body 21 and the inner end plate body 31 are square.

Embodiment 3

[0067] The difference with embodiment 1 is: as Image 6 As shown, the aperture adjuster 22 adopts the second aperture adjuster 222; the second aperture adjuster 222 includes a second base pipe 2221 that can be movably arranged on the outer end plate body 21, and two installations arranged inside the second base pipe 2221 Pad 2222, an extrusion ring 2223 arranged between the two installation pads 2222, two extrusion blocks 2224 respectively arranged on the upper and lower ends of the extrusion ring 2223 and two respectively passing through the upper and lower surfaces of the second base pipe 2221 Adjusting bolts 2225 that are movably connected with the two extruding blocks 2224 respectively.

[0068] When the communication maintenance system proposed in this embodiment is used to pass the cable through the environmental bulkhead panel: before the cable is passed through the aperture regulator 22, the adjusting bolt 2225 needs to be adjusted to a loose state, and then the cable ...

Abstract

The invention relates to the technical field of aircraft testing, in particular to a communication maintenance system and method for aircraft test. The system comprises a maintenance suite and a sealing and heat preservation assembly which is used for carrying out the sealing and heat preservation treatment of the maintenance suite. The system is reasonable in structural design, the heat preservation and sealing performance of the cable penetrating position are effectively guaranteed through cooperative use of the maintenance kit and the sealing and heat preservation assembly, the phenomena of condensation, freezing and the like caused by cable penetration are further avoided, and the test safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to a communication maintenance system and a maintenance method for aircraft testing. Background technique [0002] Since the invention of airplanes, airplanes have increasingly become an indispensable vehicle for modern civilization. With the advancement of science and technology and the continuous development of aviation technology, the performance of aircraft has also been continuously improved. Aircraft test engineering plays a vital "role" in the development of aviation technology. [0003] Aircraft test engineering includes interrupted takeoff test, "tail" test, stall test, extreme weather test, fatigue test, water splash test, bird strike test, lightning strike test and other test items. In extreme weather testing, it is necessary to use the climate environment laboratory to carry out the test. [0004] The climate and environment laboratory has the ability to carr...
