Abstract

The invention discloses a basin-shaped helicopter body made of composite materials. The basin-shaped helicopter body comprises a lower skin, a left side plate, a right side plate, a front partitioning plate and a rear partitioning plate, wherein the lower skin is positioned at the bottom of the helicopter body; the left side plate and the right side plate are arranged on the lower skin at an interval along the left-right direction and are respectively positioned at the left side and the right side of the helicopter body, and at least one of the left side plate and the right side plate is provided with an installing part for installing a power system; the front partitioning plate and the rear partitioning plate are arranged on the lower skin at an interval along the front-rear direction and are respectively positioned at the front end and the rear end of the helicopter body; the left side and the right side of the front partitioning plate are respectively connected with the front ends of the left side plate and the right side plate; the left side and the right side of the rear partitioning plate are respectively connected with the rear ends of the left side plate and the right side plate; a containing space with an opened upper end is limited by the left side plate, the right side plate, the front partitioning plate, the rear partitioning plate and the lower skin; and the left side plate, the right side plate, the front partitioning plate and the rear partitioning plate are parts made of the composite materials. The basin-shaped helicopter body disclosed by the embodiment of the invention has the advantages of light weight, good vibration damping performance, relatively direct force-transferring routine and high structure 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...
