Abstract

The invention discloses an integral molding process for a fuselage of a helicopter, and belongs to the field of helicopter preparation. The integral molding process comprises the following steps of S1: tailoring a carbon fiber prepreg; S2, laying an isolating membrane; S3, laminating the tailored carbon fiber prepreg; S4, mounting a gas guiding system on the outer surface of the carbon fiber prepreg; S5, performing heating treatment by an autoclave; and S6: taking. The carbon fiber prepreg is used as a raw material, the fuselage of the helicopter in all angles has high strength through lay-updesign, a split module set and a vacuum bag enables the strength of the interior of the fuselage of the helicopter to reach the requirements through an autoclave molding technology, the assembly of the interior is ensured, the fuselage of the helicopter is high, the process is simple and easy to operate, the molding time is short, the product size is accurate and controllable, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of helicopter preparation, in particular to an integral molding process of a helicopter fuselage and the like. Background technique [0002] Helicopter is mainly composed of fuselage, lift (including rotor and tail rotor), power, transmission and airborne flight equipment. The rotor is generally driven by a turboshaft engine or a piston engine through a mechanical transmission system composed of a transmission shaft and a reducer, or it can also be driven by the reaction force generated by the tip jet. Divided into conventional helicopters and tilt rotor aircraft, high-speed helicopters, stealth helicopters. According to the size, it can be divided into light helicopter, medium helicopter and heavy helicopter. [0003] At present, the assembly production process is adopted in the production of the helicopter fuselage. This production process can no longer meet the needs of the existing helicopter production efficien...
