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

Embodiment Construction
[0051] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0052] The invention discloses an electrically driven folding wing system with a large aspect ratio, comprising a pulley bracket, a servo motor, a synchronous belt, a pulley shaft system, a universal coupling, a clutch shaft system, a wing shaft system, an axial compression Spring, wing shaft mount, wing, locking pin assembly, cabin. In the initial state, the wings are in the folded state. After the unfolding command is issued, the four groups of wings are driven by the servo motor to realize the unfolding function, and the locking pin assembly realizes the locking of the unfolded state of the wings. The electric-driven folding wing system with large aspect ratio described in the present invention overcomes the deficiencies of the prior art, and the design process is parameterized, which can be quickly transplanted according to the requiremen...

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...
