Problems solved by technology

At the same time, it is necessary to separate the heat and sound insulation layer from the aircraft skin, and try to prevent the condensed water generated inside the aircraft skin from entering the heat and sound insulation layer. After being absorbed by the heat and sound insulation layer, the heat and sound insulation layer will increase in weight and rot. , reducing the thermal and sound insulation performance

Abstract

The invention provides a heat and sound insulation device for an aircraft cockpit structure. The heat and sound insulation device for the aircraft cockpit structure comprises a heat and sound insulation layer, the heat and sound insulation layer is arranged between an aircraft skin and an interior trimming panel, and the space between the heat and sound insulation layer and the aircraft skin is filled with airbags. A sound insulation device used for a commercial aircraft to improve sound insulation effects of aircraft cockpits is provided, the heat and sound insulation device for the aircraft cockpit structure can reduce the noise level in the aircraft cockpits, and meanwhile, try to avoid the increase of the weight of the aircraft to improve the service life of the heat and sound insulation layer.

Description

technical field [0001] The invention relates to a heat and sound insulation device for aircraft cockpit structure, in particular to a heat and sound insulation device for reducing the internal noise level of the aircraft cockpit and suppressing the formation and damage of condensed water on the aircraft skin. Background technique [0002] Since the purpose of commercial aircraft is mainly to transport passengers, the comfort of the cabin environment of commercial aircraft is an important indicator reflecting the quality of commercial aircraft. With the continuous advancement of technology, the diversification of human comfort indicators, and the gradual popularization of civil passenger aircraft transportation , the noise level in the cabin has been paid more and more attention in the comfort design index of civil airliner. Because there are external sound sources such as external pneumatics, engines, APUs, landing gear, hydraulic pumps, etc. in civil airliners, there are al...
