Abstract

The invention discloses a cold ejection method and an ejector based on solid carbon dioxide phase change. The method comprises the following steps of accommodating carbon dioxide in the ejector in a form of solid carbon dioxide powder; heating the solid powder transiently, wherein carbon dioxide is converted from solid phase to gaseous phase or supercritical phase; and controllably ejecting the carbon dioxide gas or a supercritical fluid after phase change based on a target ejection energy.

Description

technical field [0001] The invention belongs to the field of catapult technology, in particular to a cold catapult method and catapult based on phase transition of solid carbon dioxide. Background technique [0002] The shoulder-launched missile is an individual combat weapon, which has the advantages of portability, smallest size, lightest weight, shortest range, and smallest shooting height. It is considered to be the most cost-effective light defensive weapon. At present, shoulder-launched missiles are propelled by solid rocket fuel during the boost phase, and operators need to operate at zero distance. The fuel combustion products in the initial stage of launch often contain toxic and harmful substances, which pose an inevitable safety threat to the health of operators. cause environmental pollution. If the solid carbon dioxide phase change propulsion technology is used in the boost phase, the missile is ejected several meters or even tens of meters away and then trigge...
