Technical Field

[0001] The invention relates to the field of projectile tubes, in particular to a high-voltage resistant bidirectional electric projectile tube. Background Art

[0002] In weapon systems, many combat units need to be scattered by the carrier platform to realize their combat functions. The realization of this function mainly relies on various types of pyrotechnics, such as electric separation bolts, ejection tubes, actuators, etc. Ejection tubes are widely used in weapon systems due to their rapid actuation and large gas production. Existing ejection tubes are generally "one-in-one-out" structures, that is, the product is ignited from the input end, ignites the main charge, and the main charge outputs high-temperature and high-pressure gas to complete the action process. This structure is a classic structure of an ejection tube, which has the characteristics of reliable action and simple structure, but it is necessary to provide a separate power supply for each power-generating ejection tube. When the number of combat units is large, the number and weight of the power supply will also increase, and the structure and timing design of the circuit system will also become complicated, becoming an important factor restricting the development of weapons.
