Abstract

The invention discloses a basin-shaped composite material helicopter fuselage, comprising: a lower skin, the lower skin is located at the bottom of the fuselage; On the skin and located on the left and right sides of the fuselage, at least one of the left side panel and the right side panel is provided with a mounting part for installing the power system; the front partition and the rear partition, the front partition and the rear partition along the The front and rear partitions are arranged on the lower skin and are respectively located at the front and rear ends of the fuselage. Connected with the rear end of the right side panel, the left side panel, the right side panel, the front partition, the rear partition and the lower skin define an open accommodation space at the upper end; the left side panel, the right side panel, the front partition and the rear partition The panels are composite pieces. The basin-shaped composite material helicopter fuselage according to the embodiment of the present invention has light weight, good vibration damping performance, more direct force transmission route, and high structural efficiency.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing, and more specifically, relates to a basin-type composite material helicopter fuselage. Background technique [0002] With the rapid progress of advanced composite materials and their processing technology, in the field of aircraft manufacturing, new aircraft designs are increasingly using advanced composite materials. The application of composite materials plays a vital role in the lightweight, miniaturization and high performance of aircraft structures. The composite material fuselage greatly reduces the weight of the aircraft itself while ensuring the structural strength, improves the starting elasticity, and greatly improves the starting performance and handling performance of the aircraft. [0003] At present, most helicopter fuselage structures are semi-monocoque fuselage structures, which are mainly composed of skins, long stringers and support frames. Among them, the suppo...
