Description
Technical field
The present invention relates to the launching apparatus of unmanned plane, specifically a kind of small drone launching catapult.
Background technology
Current military affairs development in science and technology is rapid, and unmanned plane is as information weapon equipment, in closely High-technology local war several times
In play increasingly important role, the flat pad of unmanned plane is also increasingly paid attention to by countries in the world.Now nobody
Machine emission system has become the important link in unmanned plane Campaign Process, gradually develop into can carry out an urgent task and
There is the advanced weaponry of adaptability to equip.
Unmanned plane is mainly used and is taken off and catapult-assisted take-off two ways on car launcher when ground is taken off.It is risen on car launcher
Fly to be that unmanned plane is mounted on car launcher, on machine under motor power effect, makes unmanned plane with launch vehicle combination body along general
Logical slideway, which is slided, to be run, and when accelerating to unmanned plane takeoff speed, discharges unmanned plane.There is complicated, systems for this radiation pattern
Make applicable of high cost, the problem of maintenance difficulty.Catapult-assisted take-off is that unmanned plane is mounted on launching cradle, is helped by solid-rocket
Power, high pressure gas or the elastic string ejector of thruster realize the method that zero-height ejection takes off.Wherein solid-propellant booster rocket
A solid combustion rocket engine, this takeoff method be applicable in a kind of more startup launch method, but transport,
The applicable security requirement of storage is high, is applicable in for it and brings big inconvenience；The manufacturing cost of High-Pressure Gas System is up to
Million yuan.
Invention content
The object of the present invention is to provide it is a kind of it is simple in structure, easy to operate, launching success rate is high, reused small-sized nothing
Man-machine launching catapult.
Realizing the technical solution of the object of the invention is：
A kind of small drone launching catapult, mainly by shot trolley, motorcycle, dragging track, rear support frame, front support
Frame, ejection rope, hoist engine, locking mechanism composition, shot trolley is placed on dragging track, be provided on trolley unmanned plane lock and
Voluntarily unlocking structure, pulley rail front end are provided with front support frame, trolley pulling force commutating structure, and rear end is provided with rear support frame,
The rear support frame of dragging track is provided with hoist engine and locking mechanism, hoist engine is connect with motorcycle by steel wire rope.
The front support frame be by the support bar group in adjustable-angle and direction at tripod.
The dragging track saves folding tracks, convenient transportation for three, and the length of track depends on the weight of unmanned plane
The size of amount and acceleration.
The shot trolley is made of the two parts detachably separated up and down, the upper directive wheel of shot trolley, lower positioning
Wheel constrains trolley and can only slide in orbit without going here and there outside errant.
It is additionally provided with short slideway at the top of the shot trolley, the ejection posture for controlling aircraft.
The ejection rope is an elastic string with strong contractility, the fixation of ejection rope one end and dragging track front end
Block connects, and the other end is connected with trolley, and the pulling force for launching rope is divided into 4-6 section by the guide pulley on trolley, per area
Between pulling force mean allocation.The steel wire rope of hoist engine is connect with motorcycle, and motorcycle in the centre of ejection rope, passes through hoist engine band by the waist
Dynamic motorcycle changes toward post-tensioning and launches the length of rope between trolley and the fixed block of front end to change the pulling force of ejection rope.
The locking mechanism, including fixing lock and bumper bar energetically, fixing lock are a clamp-buckle, haul trolley, bumper bar
To cross trolley and track, insurance leans on external force to release, and trolley slowly stops at ratio wheel after ejection.
The application method for the launching cradle that this small drone is taken off is：
1, shot trolley is pulled to trolley starting point, locking in a free state；
2, unmanned plane to be launched is installed on trolley；
3, ejection rope is tensed by hoist engine, makes trolley that there is the elastic potential energy of some strength；
4, small lock is unlocked, trolley potential energy is converted into kinetic energy and unmanned plane is driven to generate an acceleration, passes through cunning from starting point
Row track moves to trolley ratio wheel, and the speed disengaging trolley that unmanned plane reaches certain takes off；
5, after trolley crosses ratio wheel, due to reversely restraining force effect, trolley is zero in deceleration final position relative velocity；
6, trolley returns to trolley ratio wheel position under the action of reversed holdback force；
7, hoist engine is unclamped, ejection rope is loosened, trolley is pulled under start position prepares and is once launched.
The beneficial effects of the invention are as follows：Small-sized pilotless aircraft launching cradle is simple in structure, at low cost, easy to operate, nobody flies
Machine takes off, and success rate is high, and safe operation, ejection rope is hardly damaged, launching cradle long lifespan.
