Embodiment Construction

[0029] In order to make the object, technical solution and effect of the present invention clearer and clearer, the following examples are given to further describe the present invention in detail. It should be pointed out that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as figure 1 As shown, the auxiliary driving device for folding wings proposed by the present invention mainly includes a transmission device for converting rotary motion and linear motion and a solid-liquid mixed spring for energy storage, and also includes connecting parts with the inner wing and the shaft. mechanical device.

[0031] The working method of the folding wing auxiliary driving device of the present invention:

[0032] When the wings are unfolded, gravity does work, and the main drive works to provide the wings with a moment to overcome the gravity, and the external force distributed to the auxilia...

Abstract

The invention relates to an auxiliary driving device for folding wings based on a solid-liquid mixed spring, which belongs to the field of aeronautical structure design. The auxiliary driving device includes a transmission device and a solid-liquid mixed spring mechanism, and the solid-liquid mixed spring mechanism includes a main hydraulic cylinder and is connected to it through an oil delivery pipe. Several split hydraulic cylinders; the folding wing auxiliary drive device of the present invention can store the work done by the external force when the wing is unfolded, and play it back when the wing is folded to provide a part of the driving force to assist the main drive, which can reduce the impact on the main drive. The demand for driving capacity of the driver; and the use of solid-liquid hybrid spring energy storage, through the hydraulic cylinder to transmit force and displacement stroke, the spring is placed in any position inside the wing that is not sensitive to weight and space size, which solves the airfoil's impact on space size and space size. Weight limit problem.

Description

technical field [0001] The invention belongs to the field of aeronautical structure design, and in particular relates to an auxiliary driving device for folding wings based on a solid-liquid hybrid spring. Background technique [0002] The wing folding technology can save the space occupied by the deck when the carrier-based aircraft is parked, and can also fold the wings during flight to increase the flight stability. The driving device plays an important role in the process of wing folding and unfolding, and it is necessary to select a suitable driving device according to the specific load requirements and installation space. At present, the driving devices of folding wings mainly include the following types: electric motor drive, pneumatic / hydraulic drive and hybrid drive, and the drive is equipped according to the specific load situation; but when the load is relatively large, the size of the drive needs to be increased and the space occupied And the weight is relativel...
