Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0040] The invention provides a rubber deicing airbag used for deicing when the wing or tail of a turboprop fixed-wing aircraft freezes, and discloses the product structure, skeleton material, surface rubber layer, middle rubber layer and base fabric of the rubber deicing airbag The formula of the adhesive layer and the manufacturing process and process of the product, etc.

[0041] The shape of the deicing airbag is consistent with the deicing area of ​​the aircraft wing or empennage. The total thickness is 2.2-2.6mm. Narrowed, with a composite skeleton layer distributed inside and an inflatable airway, the airway is a parallel structure with connected ends.

[0042] The section structure of the deicing airbag is as follows: figure 1 As shown, it includes an outer layer ...

Abstract

The invention provides a rubber deicing airbag for a turboprop aircraft. The rubber deicing airbag sequentially comprises outer layer rubber, middle layer rubber, a composite skeleton layer, base cloth and bottom layer rubber, the outer layer rubber adopts chloroprene rubber, the middle layer rubber adopts natural rubber and chloroprene rubber, and the composite skeleton layer comprises surface cloth, isolation cloth and air chamber base cloth which are formed by sewing a high-strength nylon fabric material, an air channel is formed between the surface cloth and the isolation cloth, and the air channel is communicated with the exterior of the airbag through an air tap; and the bottom layer rubber is made of low-temperature chloroprene rubber, and the bottom cloth is made of nylon and is bonded with a deicing area of a wing or an empennage. The rubber deicing airbag is suitable for deicing wings and empennages of turboprop aircrafts, and can meet the working requirements of inflation and deflation deicing under the low-temperature condition.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to an aviation deicing airbag. Background technique [0002] Due to the flight height and speed of turboprop fixed-wing aircraft, the windward surfaces of the wings and tail are prone to icing during flight, which affects flight safety. In order to improve the safety of turboprop fixed-wing aircraft, anti-icing function must be provided. There are three types of deicing methods commonly used in turboprop fixed-wing aircraft: electric deicing, chemical deicing and airbag deicing. Airbag deicing is one of the effective deicing methods with short time and low power consumption. [0003] The deicing airbag was first developed by Goodrich Corporation of the United States and applied to military turboprop aircraft. Goodrich Corporation has carried out theoretical research on the application of turboprop aircraft, and the transfer of this technology is strictly prohibited. In Eu...
