Laterally-arranged single-vertical-fin patrolling device with vertical fin unfolding device

Abstract

The invention discloses a laterally-arranged single-vertical-fin patrolling device with a vertical fin unfolding device, which is characterized in that a vertical fin is fixedly connected with a vertical fin rotating shaft and a tension spring hook, an elastic check ring is sleeved on the vertical fin rotating shaft, and the tension spring hook can slide in a guide groove of an elastic body side plate; the second end of the tension spring hook is connected with the first end of the tension spring, the second end of the tension spring is fixed in the bomb body, and when the vertical fin is in afolded state, the tension spring is in a stretched state. The single side-mounted foldable vertical fin is adopted in the patrolling device, the number of two vertical fins of a traditional patrolling device is reduced to one, the number of folding wing faces of the patrolling device is reduced while the requirement for course static stability is met, and therefore the structural weight of a missile body is reduced, and the number and complexity of folding mechanisms are reduced; according to the vertical fin unfolding device, a tension spring is adopted for providing driving force, frictionforce in the vertical fin rotating process is reduced by additionally arranging a roller pin end face bearing, vertical fin rotating limiting is achieved by reserving a guide groove in the side wall of the missile body, and the unfolding device is simple, reliable, light in weight and small in installation occupied space.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a side-mounted single vertical-tail cruiser with a vertical-tail deployment device. Background technique [0002] Cruiser is an unmanned aerial platform, which is usually launched by platforms such as transport planes, rockets, and dispensers, or launched by ground launchers. It is mainly used for reconnaissance and combating "time-sensitive targets." Since it needs to be loaded in the launch platform or launch tube, its aerodynamic wing needs to be able to fold. In order to meet the folding loading requirements, traditional cruisers usually adopt a tandem wing layout scheme with two pairs of front and rear main wing surfaces, and the control rudder surface is usually located on the trailing edge of the rear wing, such as the "Switchblade" (Switchblade) developed by the United States. , the loitering bomb "Coyote" (LOCUST) developed by the United Sta...

AI Technical Summary

Problems solved by technology

A large number of folding wings will lead to an increase in the number of folding mechanisms, complex folding mechanisms, reduced reliability, and an increase in structural weight. The deployment device is as simple and reliable as possible to improve the reliability of the whole machine
