Electric folding wing system with high aspect ratio

Abstract

The invention discloses an electric folding wing system with a high aspect ratio, which comprises a pulley support, a servo motor, a synchronous belt, pulley axle systems, universal couplings, clutchaxle systems, elastic wing axle systems, axial compression springs, elastic wing rotating shaft mounting seats, elastic wings, locking pin assemblies and a cabin body. At the initial state, the wingsare in the folded state. After an unfolding command is issued, the unfolding function of four groups of elastic wings is realized under the driving of the servo motor, and the unfolding state of the elastic wings is locked by the locking pin assembly. The electric folding wing system with the high aspect ratio overcomes shortcomings of the prior art, parameterization of the design process is realized, the system can be transplanted quickly according to different weapon system requirements. The system has the advantages of simple mechanism, reliable function, small envelope size in folded state, good aerodynamic shape in unfolded state, less space occupation by the mechanism inside the cabin, smoothness and no impact in working process, and can be used as a large aspect ratio folding wing assembly of an airborne, ground-based and water-surface barrel-launched missile.

Description

technical field [0001] The present invention relates to a new type of electric-driven folding wing system with large aspect ratio, in particular to a folding wing mechanism that effectively reduces storage space and greatly increases weapon range, and can be applied to various wing layouts with large aspect ratio Airborne, ground, and water-surface barrel-launched missiles, as well as similar aerodynamically shaped cruisers, unmanned aerial vehicles, and other aircraft. Background technique [0002] In order to meet the operational requirements of standoff strikes and low collateral damage in modern warfare, the range requirements of flying missiles are constantly increasing. At the same time, weapons should have as compact a structure as possible when mounted on a carrier aircraft or launched on the ground or water. The requirements of long range and small size make more and more combat weapons adopt the layout of folding wings. [0003] Traditional folding wing systems us...

AI Technical Summary

Problems solved by technology

The outer envelope size of the horizontal folding method is affected by the wingspan of the projectile, which is not suitable for aerodynamic layout with large aspect ratio

The structural layout of the longitudinal folding method commonly used at present is greatly affected by the chord length of the wings, and the longitudinal inline groove opened on the cabin or the mounting seat outside the cabin will have a great impact on the structural strength and aerodynamic shape. The wings of the cabin also greatly squeezed the interior space of the cabin
