Abstract

The invention belongs to the technical field of engine maintenance equipment design, and particularly relates to a composite material adjustable stator blade which comprises an upper shaft neck, a lower shaft neck, an upper marginal plate, a lower marginal plate, and a blade body; besides, the blade is divided into a central layer plate area, a central filling area, a reinforced layer plate area and a molded surface structure area, the central layer plate area and the reinforced layer plate area are composed of laminated plates formed by laying composite material prepregs, the central fillingarea is composed of composite material prepregs, and the molded surface structure area is composed of resin or single-layer prepregs covering the surface of the molded surface structure area; and thecentral layer plate area and the central filling area form a core bearing area of the blade, the reinforced layer plate area is located on the two sides of the core bearing area, and the molded surface structure area is used for ensuring that the composite material adjustable stator blade is smooth in appearance. According to the composite material adjustable stator blade, the design feasibility and engineering problems of the composite material adjustable stator blade are effectively solved, the problems that the blade configuration is complex, and layering is difficult to achieve are effectively solved, and the pneumatic bending moment and pneumatic torque resistance of the composite material adjustable stator blade is improved.

Description

technical field

[0001] The application belongs to the technical field of engine maintenance equipment design, and in particular relates to an adjustable stator vane made of composite material. Background technique

[0002] Resin-based composite material blades are widely used in aero-engines. A lot of research has been carried out on composite materials abroad. At present, composite material blades have been applied to GE90, GEnx, TRENT1000, TRENTXWB and LEAP-X and other engines. Compared with titanium alloy blades, composite material fan blades have the characteristics of light weight, high efficiency and low noise, and have better anti-flutter performance and damage tolerance capabilities. At the same time, the anti-bird strike performance can also meet airworthiness requirements.

[0003] At present, resin-based composite materials are mainly used in aero-engine components such as external culvert casings, fan rotor blades, and stator segments (non-adjustable). Single, s...
