Thermal acoustic insulation and insulation blanket for aircraft

Abstract

The invention provides a thermal insulation and acoustic insulation blanket for an aircraft. An inner lining is connected into the fuselage wall of the aircraft. The thermal insulation and acoustic insulation blanket includes a thermal insulation and acoustic insulation blanket body, a heating layer is arranged on the side, towards the fuselage wall, of the thermal insulation and acoustic insulation blanket body, and / or, a heating layer is arranged on the side, away from the fuselage wall, of the thermal insulation and acoustic insulation blanket body. According to the thermal insulation and acoustic insulation blanket for the aircraft, the heating layer can heat a fuselage of the aircraft, ice of the fuselage can be effectively removed, and condensate water of the thermal insulation and acoustic insulation blanket can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of aircraft manufacturing, in particular to a thermal acoustic insulation blanket (TAIB, thermal acoustic insulation blanket) used on aircraft. Background technique [0002] In cold weather, in order to reduce the significant resistance generated by the ice layer formed on the surface of the body when taking off, airplanes and other aircraft need to perform deicing procedures before taking off in cold weather. Traditional deicing procedures are mostly implemented with antifreeze-based deicing agents, but this antifreeze deicing method has the disadvantages of time-consuming, laborious, and low environmental protection. In another case, the aircraft is ready for deicing before takeoff, but cannot take off in time due to some unexpected events. At this time, the aircraft body needs to be deiced again before taking off again, which makes the deicing process more time-consuming and laborious. . In recent years...

Traditional deicing procedures are mostly implemented with antifreeze-based deicing agents, but this antifreeze deicing method has the disadvantages of time-consuming, laborious and low environmental protection

In another case, the aircraft is ready for deicing before takeoff, but cannot take off in time due to some unexpected events. At this time, the aircraft body needs to be deiced again before taking off again, which makes the deicing process more time-consuming and laborious.

In recent years, there have been some new inventions, such as the use of electrothermal methods to deice. Electrothermal deicing can be used on the whole aircraft in theory, but in actual use, due to the complex structure of the aircraft fuselage, it can only be processed for the wings, or even not yet widely used

[0003]As mentioned above, the current deicing method for the fuselage is still mostly the traditional antifreeze method, and the current electric deicing method is due to the The complex structure makes it difficult to be practically applied. For example, adding a complete set of corresponding electric heating facilities to the fuselage alone will cause the weight of the fuselage to far exceed the design weight of the aircraft.
