The utility model aims at overcoming the above-mentioned problem, provide a coaxial helicopter pneumatic catapult.
In order to achieve the purpose, the utility model discloses a method is: a pneumatic catapult for a coaxial helicopter comprises a launching tube and an air supply mechanism connected with the launching tube, wherein the air supply mechanism comprises an air storage tank which is connected with the launching tube through a pipeline; the launching tube is internally provided with a piston, the launching tube is internally provided with a coaxial helicopter complete machine, the lower end of the coaxial helicopter complete machine is contacted with the upper end of the piston, and a body of the coaxial helicopter complete machine is provided with a guide mechanism which is used for moving and guiding the coaxial helicopter complete machine in the launching tube.
As the utility model discloses a preferred, the gas holder still be connected with the controller, the controller is used for controlling the gas volume that the high-pressure gas of gas holder launches the launch canister.
As a preferred choice, the piston with the inner wall clearance flexible fit of launching tube, the lower extreme of launching tube still is provided with the spacing boss of piston, the spacing boss of piston will the piston restriction is in on the spacing boss of piston.
As the utility model discloses a preferred, guiding mechanism include support arm and support arm bearing, the support arm with coaxial helicopter fuselage fixed connection, support arm bearing pass through the support arm outer end axle with support arm hinged joint.
As the utility model discloses a preferred, the support arm bearing with launch canister inner wall clearance fit.
Has the advantages that:
the utility model discloses the pneumatic jettison device of coaxial helicopter that technical scheme provided is simple reliable, and disguise is good, easily manufacturing, can conveniently realize the quick launch of coaxial helicopter and take off.

Detailed Description
The present invention will be further clarified by the following embodiments with reference to the attached drawings, which are implemented on the premise of the technical solution of the present invention, and it should be understood that these embodiments are only used for illustrating the present invention and are not used for limiting the scope of the present invention.
Example 1:
as shown in fig. 1, the pneumatic catapult for coaxial helicopter disclosed in this embodiment includes a launcher 1, a coaxial helicopter complete machine 2, a piston 3, a pipe 4, a controller 5, and an air tank 6. Wherein, the gas holder 6 is connected with the lower end thread sealing of the launching tube 1 through the pipeline 4, and the barrel discharging speed of the coaxial helicopter complete machine 2 is controlled by controlling the amount of the gas passing from the gas holder 6 to the launching tube 1 through the controller 5. The piston 3 is in flexible clearance fit with the inner wall of the launching tube 1. The coaxial helicopter complete machine 2 after the coaxial helicopter blades are folded is arranged in the launching tube 1 and is contacted with the upper end of the piston 3.
As shown in fig. 2 to 4, which are schematic structural diagrams of the coaxial helicopter whole body disclosed in this embodiment, the support arm 9 is fixedly connected to the coaxial helicopter body 10. The supporting arm bearing 7 is hinged with the supporting arm 9 through a supporting arm outer section shaft 11. When the folded coaxial helicopter blade 2 is placed in the launch barrel 1, the support arm bearing 7 is in clearance fit with the inner wall of the launch barrel, and the folded coaxial helicopter blade 2 can freely slide in the launch barrel 1.
As shown in fig. 5, the piston 3 is in clearance flexible fit with the inner wall of the launching tube 1, the lower end of the launching tube 1 is provided with a piston limit boss 12, and the piston 3 is limited on the piston limit boss 12 by the piston limit boss 12.
The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the technical means, but also comprises the technical scheme formed by the arbitrary combination of the technical characteristics. The foregoing is a detailed description of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations are also considered as the protection scope of the present invention.
