Pneumatic high-speed throwing device

Abstract

The invention relates to a pneumatic high-speed throwing device, belonging to the field of aircrafts, in particular to the pneumatic high-speed throwing device which is placed in a narrow space. The device has the functions of clamping and high-peed throwing, and comprises a throwing device and a clamping device, wherein the throwing device consists of an air cylinder with double piston rods and four air ports, an upper piston rod and a lower piston rod. The clamping device comprises two synchronous shafts, two rolling sleeves, two bending plates, two middle rotating shafts, two lower rotating shafts, two V-typed clamps and two tensioning springs. The device can be used in a narrow installation space and a short stroke space to realize large throwing force, a high speed and an angle, the separation and throwing are carried out simultaneously, and respective control on separation and throwing is not needed to be considered. According to the device, a throwing device is integrated, the device can be installed according to a required angle, the installation is convenient, the size is small, and the clamping of throwing materials are extremely convenient.

Description

technical field [0001] The invention belongs to the field of aircraft, in particular to a pneumatic high-speed delivery device placed in a narrow space, which has the functions of clamping and high-speed delivery. Background technique [0002] At present, the development of aircraft requires light-load, stealth, high-speed and other performances. It usually needs to drop objects on the ground at high speed according to the actual situation during the flight, such as materials and external objects. Due to the turbulence area generated by the air flow during high-speed flight will affect the separation process of the drop, in severe cases, the drop may not be able to separate and hit the aircraft itself. Therefore, the projectile must be released with a certain high initial velocity and a large pitch angle, which requires a device suitable for high-speed delivery. At the same time, the stealth characteristics of the aircraft require that the size of the delivery device cannot...

AI Technical Summary

Problems solved by technology

The advantage of this design is that the use of pneumatic components can ensure the safety of delivery, avoid safety hazards and inaccurate time control caused by the explosion bolts breaking off, and at the same time, the delivery force can be easily adjusted within a certain range through the pneumatic pressure adjustment device. The release method needs multiple pneumatic actuators to complete, the size is large, and it is not suitable for built-in installation in a narrow space, and it is difficult to ensure the synchronization of double-cylinder release, which will have a great impact on the release speed and angle, especially the design of the release pin needs to be changed. The surface shape of the object is not suitable for occasions with high requirements on the surface of the object
