Unmanned plane gas-powered catapult

Technical field

The utility model is related to unmanned aerial vehicle ejector, more particularly to a kind of unmanned plane gas-powered catapult.

Background technology

In recent years, with the development of science and technology, unmanned plane plays more and more important effect in every field, various The unmanned plane of model is developed.

Higher speed is needed when unmanned plane takes off, because its own propulsion capability is limited, it is impossible to obtain effective initial Takeoff speed, therefore pushed before take-off using unmanned aerial vehicle ejector, make it have certain takeoff speed.

Unmanned aerial vehicle ejector one has two classes, and a class is unmanned plane mechanical elastic emitter, and another kind of is the pneumatic ejection of unmanned plane Device, because unmanned plane gas-powered catapult has the advantages that fast response time, therefore is widely adopted.

Existing unmanned plane gas-powered catapult, including gas pressure tank, connect the conduit of gas pressure tank, are arranged in conduit Internal piston, stand, wing lift component and the support being connected to below conduit composition.Stand is used to carry unmanned plane machine Body, wing lifts the wing that component is used to lift unmanned plane, and support is used for support stand, conduit and stand, conduit is had conjunction Suitable inclination angle, and then make it that unmanned plane has suitable take-off angle.

When gas pressure tank discharges gas, gas can promote piston to fly out conduit, and piston promotes unmanned plane to fly to aerial, Initial velocity is made it have, after piston kinetic energy exhausts, ground is fallen to.

Existing unmanned plane gas-powered catapult corresponding speed is fast, the initial kinetic energy that unmanned plane acquisition can be made higher, but nothing Wing is lifted both component and conduit and is vertically arranged in man-machine gas-powered catapult, while catheter length is longer, wing lifts component Amplitude it is wider, it is very inconvenient when transport, transfer so unmanned plane gas-powered catapult can take substantial amounts of space resources.In order to Conveniently copy mechanically, wing is lifted component usually using bolt and installed on conduit by people, wing is lifted into component when transport, transfer and torn open Remove, then transported again.

So every time using unmanned plane gas-powered catapult when, staff will demolition, installation wing lift component, using very It is inconvenient.
