Abstract

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 requirements of different weapon systems, and has simple mechanism, reliable function, and outsourcing of the folded state. The network is small in size, has a good aerodynamic shape in the unfolded state, the mechanism occupies less space inside the cabin, and the working process is smooth and without impact. It can be used as a large aspect ratio folding wing assembly for airborne, ground, and water surface barrel-launched missiles use.

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...
