Single-power-source synchronous driving type secondary folding and unfolding mechanism for guided missile

Abstract

The invention discloses a single-power-source synchronous driving type secondary folding and unfolding mechanism for a guided missile. A motor drives a small gear, the small gear is engaged with an arc rack, the arc rack is fixed to a first annular piece, the first annular piece and three second annular pieces are fixed end to end to form a circular ring, and the circular ring and a circular arc groove in a base form a sliding pair; and the first annular piece or the second annular pieces are each hinged to one end of a push rod, the other ends of the push rods are hinged to corresponding middle wings, two wing root connectors of each wing root are hinged to two lower connection holes of the corresponding middle wing, an outer wing connector of each outer wing is hinged to two upper connection holes of the corresponding middle wing, one end of each connection rod is hinged to the corresponding push rod, the other end of each connection rod and the corresponding outer wing are hinged atthe position of an outer wing pin hole, and spring locking mechanisms are arranged between the wing roots and the middle wings. Unfolding and locking of four folding wings are achieved through driveof a single power source, and the internal occupied space of the guided missile is small.

Description

technical field [0001] The invention belongs to the technical field of aerospace and relates to a missile folding wing unfolding mechanism, in particular to a single power source synchronously driven secondary folding and unfolding mechanism for missiles. Background technique [0002] Folding wings can reduce the lateral size of the missile body, reduce the volume of the launching device, increase the carrying capacity of vehicles, ships or aircraft, and improve the combat effectiveness of the weapon system. The function of the folding wing unfolding mechanism is to make the wing surface fold before launch, and automatically unfold and lock reliably under the action of driving force after launch. Most of the wing surface folding and unfolding mechanisms currently used are one-time folding. When the wingspan is large, the one-time folding wing can no longer meet the requirements of reducing the lateral size of the missile, and when it is fully deployed, it will have a greater...

Problems solved by technology

Most of the wing surface folding and unfolding mechanisms currently used are one-time folding. When the wingspan is large, the one-time folding wing can no longer meet the requirements of reducing the lateral size of the missile, and when it is unfolded in place, it will have a greater impact on the missile body. Affect the flight stability of the missile
