Aircraft supporting framework

Abstract

The invention provides an aircraft supporting framework. The aircraft supporting framework comprises a first windshield framework, a second windshield framework, a first side window framework and a second side window framework, wherein profiles of the first windshield framework and the second windshield framework are in the shape of P, one side of the second windshield framework is spliced with one side, away from the second windshield framework, of the first windshield framework to form a windshield framework, and the windshield framework is in the shape like a Chinese character 'yuan'; a profile of the side window framework is in the shape of P, one side of the side window framework is spliced with one side, away from the second windshield framework, of the first windshield framework, wherein a convex part of the first windshield framework is spliced with a convex part of the first side window framework to form a first supporting leg, and a profile of the second side window frameworkis in the shape of P; one side of the second side window framework is spliced with one side, away from the first windshield framework, of the second windshield framework, wherein a convex part of thesecond windshield framework is spliced with a convex part of the second side window framework to form a second supporting leg, the first windshield framework, the second windshield framework, the first side window framework and the second side window framework are all made of a composite material, and integrated to be formed by a vacuum bag forming method.

Description

technical field [0001] The application belongs to the technical field of aircraft support frame structure design, and in particular relates to an aircraft support frame. Background technique [0002] As the rigid support structure of the aircraft nose canopy, the aircraft support frame is designed to transmit the flight load of the aircraft nose and its own inertial load. On the one hand, it is connected with the front skin, side skin, bottom skin and The top skin is connected, and it is necessary to provide support for the connected skin to maintain the shape of the skin; on the other hand, it is necessary to install windshield glass, side-view glass and top-view glass on it to form a relatively airtight space. And the external environment can be observed through the installed glass. [0003] At present, aircraft support frames are mostly composed of |-shaped, L-shaped, and C-shaped parts to form a lumen structure of the support frame, which is used to transmit load and di...

AI Technical Summary

Problems solved by technology

The parts that are combined and assembled to form a supporting skeleton are mostly made of molds. In the production process, a large number of molds are used. There are many assembly surfaces and tooling positions, and the production cycle is long. In most cases, there are a large number of molds. The curved surface and the separation surface of the process are not easy to set, which makes the later assembly difficult; in addition, the supporting frame is assembled with a large number of parts and components, there are gaps between the parts, the load transmission is not very direct, and the assembly between the parts requires a lot of additional connectors, creating excess weight burden
