Abstract

The invention discloses a solid-liquid hybrid spring energy storage device, and belongs to the technical field of aviation structure design. The solid-liquid hybrid spring energy storage device is composed of a hydraulic cylinder and a solid spring, wherein the hydraulic cylinder comprises a main hydraulic cylinder and shunting hydraulic cylinders, the two kind of hydraulic cylinders are connectedthrough oil pipes, the main hydraulic cylinder is fixed at a rotating shaft of a folding wing, the shunting hydraulic cylinders are fixed in the part where is spacious in space and poor in influenceof the weight on the performance of an aircraft so as to realize energy storage, a plurality of the shunting hydraulic cylinders can be arranged, and the volume of the liquid in the shunting hydrauliccylinders is equal to the volume of the liquid discharged from the main hydraulic cylinder. According to the device, the area ratio of the main hydraulic cylinder and the area ratio of the shunting hydraulic cylinders is designed, the number of the shunting hydraulic cylinders is designed, so that the proportion of force and displacement can be redistributed, and the requirements of the working load, displacement stroke, the rigidity and the like of the spring can be met.

Description

technical field [0001] The invention belongs to the technical field of aeronautical structure design and relates to a solid-liquid hybrid spring energy storage device. Background technique [0002] Folding-wing aircraft can fold up the wings during flight to increase flight stability; when carrier-based aircraft are parked, folding the wings can reduce the occupied space and increase the number of carrier-based aircraft parked. Among them, the rotary drive device is a key technology. The selection of the rotary drive device is related to the size of the load. For large loads, the rotary drive device needs to increase the inner diameter of the actuator to meet the power demand, and its volume and weight will be relatively large. [0003] To increase the load capacity, an auxiliary rotary drive device can also be used to store the gravitational work when the wings are unfolded, and release them when the wings are folded, reducing the power demand of the main drive. The spring...
