Embodiment 1

[0039] Such as figure 2 , 5 As shown, a kind of anti-freezing and thawing floor for aircraft test includes a composite floor 1 and an anti-freezing and thawing device 2 located below the composite floor 1. The composite floor 1 includes a frost-resistant concrete layer 11 from top to bottom, a moisture-proof and air-insulating Layer 12, the second foam glass insulation layer 13 and the moisture-proof concrete layer 14, between the frost-resistant concrete layer 11 and the moisture-proof air barrier layer 12, between the moisture-proof air barrier layer 12 and the second foam glass insulation layer 13 are all provided with double-layer PE film;

[0040] Such as Figure 3-5 As shown, the central part of the anti-freezing and thawing device 2 is provided with a main groove 21, and the two sides of the main groove 21 are symmetrically provided with 7 components of the groove 22, and each component of the groove 22 is provided with a set of Exhaust fans 23 for ventilation are p...

Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, except that the number of sets of water suction machines 49 is different.

[0045] Such as Figure 5 , 6 As shown, the drainage assembly 4 includes a liftable outer transfer block 41 and an inner transfer block 42, an outer vacuum transfer belt 43 and an inner vacuum transfer belt 44 located below the outer transfer block 41 and the inner transfer block 42, and the outer transfer block 41 and the inner transfer block The top of 42 is connected by several strip grids 45. Inside the inner vacuum conveyor belt 44, there is a lifting motor 46 for controlling the lifting of the inner transmission block 42. When the lifting motor 46 is not turned on, the strip grids 45 are arranged in parallel with the composite floor 1. Both the bottom and the outer wall of the vacuum conveyor belt 43 are provided with teeth 47, the interior of the composite floor 1 is provided with a tooth groove 15 meshing with the teeth 47 on the out...

Embodiment 3

[0047] This embodiment is basically the same as Embodiment 1, except that the number of sets of water suction machines 49 is different.

[0048] Such as Figure 5 , 6 As shown, the drainage assembly 4 includes a liftable outer transfer block 41 and an inner transfer block 42, an outer vacuum transfer belt 43 and an inner vacuum transfer belt 44 located below the outer transfer block 41 and the inner transfer block 42, and the outer transfer block 41 and the inner transfer block The top of 42 is connected by several strip grids 45. Inside the inner vacuum conveyor belt 44, there is a lifting motor 46 for controlling the lifting of the inner transmission block 42. When the lifting motor 46 is not turned on, the strip grids 45 are arranged in parallel with the composite floor 1. Both the bottom and the outer wall of the vacuum conveyor belt 43 are provided with teeth 47, the interior of the composite floor 1 is provided with a tooth groove 15 meshing with the teeth 47 on the out...

Abstract

The invention discloses an aircraft test anti-freezing and anti-thawing terrace and an anti-freezing and anti-thawing parameter optimization method. The aircraft test anti-freezing and anti-thawing terrace comprises a composite terrace body and an anti-freezing and anti-thawing device located below the composite terrace body, a main ground groove is formed in the middle of the anti-freezing and anti-thawing device, and a plurality of branch ground grooves are symmetrically formed in the two sides of the main ground groove; a plurality of anti-freezing and anti-thawing pipes are arranged between every two groups of branch ground grooves located on the same side, the front ends of one group of anti-freezing and anti-thawing pipes in all the corresponding anti-freezing and anti-thawing pipes in the branch ground grooves are water inlet pipe sections vertically and upwards penetrating through the composite terrace body, and the tail ends of each group of anti-freezing and anti-thawing pipes are water drainage pipe sections vertically and downwards. The water inlet pipe section is correspondingly connected with a drainage assembly embedded in the surface of the composite terrace body, and two mooring assemblies are symmetrically arranged in the middle of the composite terrace body. The anti-freezing and anti-thawing terrace can effectively prevent bottom layer soil from being frozen and thawed, avoids terrace structure damage, is excellent in bearing capacity, can meet the wheel pressure load of a large passenger plane, is high in structural strength and provides large fixing force for mooring.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to an anti-freeze-thaw floor for an aircraft test and a method for optimizing anti-freeze-thaw parameters. Background technique [0002] In the field of aerospace, research on aviation aircraft has never stopped, because aircraft, as an important tool in modern industry, plays a pivotal role in many fields. In the process of researching aircraft, various tests are inevitably required, among which The most difficult conditions to simulate are climate conditions, so the aircraft climate and environment laboratory is required as a place for aviation aircraft simulation tests. [0003] At the same time, the requirements and standards for the climate and environment laboratory are relatively high. As a large-scale carrying facility equipped with environmental tests, it can accommodate full-size aircraft, special vehicles and other equipment, and can provide all-weather, time-fre...
