An air cannon launching device with uniform air flow

Abstract

The invention provides a launching airflow-uniform air cannon launching device. The device comprises an air compressor, an intake valve, an air chamber, a launching valve, a first pressure sensor, a second pressure sensor, a quick release mechanism, a PLC, a laval acceleration pipe and a launching pipe; the air compressor is connected with an air inlet of the air chamber through the intake valve;an air outlet of the air chamber is connected with one end of the quick release mechanism through the launching valve; the other end of the quick release mechanism is connected with the launching pipethrough the laval acceleration pipe; the first pressure sensor is arranged in the air chamber for monitoring the pressure value in the air chamber; the second pressure sensor is arranged on the launching valve for monitoring the pressure value of released gas in the launching valve; and the PLC is electrically connected with the intake valve, the launching valve, the first pressure sensor, the second pressure sensor and the quick release mechanism. The device enables launching airflow to quickly, uniformly and largely flow out within shorter time to act at the bottoms of cannons to push the cannons to move.

Description

technical field [0001] The invention relates to an air cannon launching technology, in particular to an air cannon launching device with uniform launching air flow. Background technique [0002] The air cannon is a special launching device. Its working principle is to use compressed air energy storage to convert a part of the internal energy stored in the gas chamber into the kinetic energy of the projectile in the barrel to complete the launching task. Compared with conventional artillery, although air cannon is less powerful, it has advantages that conventional artillery cannot replace. For example, the temperature of the barrel when it is fired is much lower than that of ordinary artillery, so it can be used to launch materials that are not resistant to high temperatures, such as test instruments and rescue supplies. [0003] Traditional air cannon pressure release mechanisms include piston type, double-membrane rupture type, and wrap-around type, etc. Some of them have ...

AI Technical Summary

Problems solved by technology

However, on the one hand, the diaphragm is made of aluminum, and after rupture, it will move toward the projectile with the high-speed jet flow, posing a safety hazard; on the other hand, the groove depth of the prestressed groove corresponds to the prestressed design method, which will cause the actual launch speed to differ from the designed launch rate. There is a large error in speed

In addition, the ruptured membrane pressure release mechanism cannot be reused, so it consumes a lot, and it is difficult to ensure the uniform effect of the emitted airflow
