Non-combustible phase change thermal thruster

Abstract

The invention belongs to the technical field of power engineering and particularly relates to a non-combustion-type phase-change heat transfer thrust device. The non-combustion-type phase-change heattransfer thrust device comprises a spray tube, a flow guiding plate, a spray opening, a tail vane, a spiral tube, an electrical heated tube, a blanking cover, a cold chamber, a liquid injection tube,a piston, a loading cabin, a detonator, a timing device, an explosive, a storage tube, a hood, a sectional material, a tail block, a check ring, a first plug, a second plug, a third plug, a hot cabin,a throttling valve, a throttling rod, a reed, an outlet tube, a nozzle, an electrical heated connector, a sealing ring and a liquid outlet. Compared with the prior art, the non-combustion-type phase-change heat transfer thrust device has the following beneficial effects that (1) the technical integration is simple, and developing and guaranteeing tasks are easy; (2) the cost is low, and the economical efficiency is outstanding during large-scale use; and (3) environmental pollution is avoided, and the green concept is embodied in all links of manufacturing, adjustment and use.

Description

technical field [0001] The invention belongs to the technical field of power engineering, and in particular relates to a non-combustible phase-change thermal thrust device. Background technique [0002] The existing rocket propulsion technology is very mature and can carry out various human activities. However, compared with the diverse needs, its shortcomings are also obvious, such as complex technology, long industrial production chain, many special processes and special materials, and support missions. Heavy, high cost, pollutes the environment, and it is not economical when performing some special tasks, such as large-scale air mines, dealing with a large number of "low-altitude, small, slow" targets, large-scale artificial rainfall, and carrying out large-scale throwing tasks at low altitudes (such as metal foil), deploying aerial reconnaissance equipment, etc. [0003] Due to the extensive use of dry ice in the existing artificial rainfall technology, the vaporized ca...

[0002] The existing rocket propulsion technology is very mature and can carry out various human activities. However, compared with the diversified needs, its shortcomings are also obvious, such as complex technology, long industrial production chain, many special processes and special materials, and support tasks. Heavy, high cost, polluting the environment, when carrying out some special tasks, its economy is not enough, such as large-scale air mines, dealing with a large number of "low-altitude, small, slow" targets, large-scale artificial rainfall, and carrying out large-scale throwing tasks at low altitudes (such as metal foil), deploying aerial reconnaissance equipment, etc.

[0003] Due to the extensive use of dry ice in the existing artificial rainfall technology, the vaporized carbon dioxide is unfavorable to the atmospheric environment (the greenhouse effect is enhanced), and the gunpowder used in the launch causes serious pollution to the environment
