Abstract

Steam boost device includes combustion chamber of rocket engine, gas nozzle, outlet of gas jet, and liquid oxygen box. The said combustion chamber is positioned above the gas nozzle; and the liquid oxygen box is positioned above the combustion chamber. There is another steam boost device located above the combustion chamber. The invention adds a steam boost device between combustion chamber and liquid oxygen box. When combustion chamber is ignited, gas nozzle jets out high temperature gas, the steam boost device jets water to gas in high temperature in gas nozzle so as to form great amount of steam, and to make quantity of gas flow at outlet increase rapidly. Thus, burning isodose propellant generates larger propulsion. Advantages are: saving energy, reducing pollution, especially, reducing greenhouse effect.

Description

The steam booster of rocket propeller device

Technical field

The invention belongs to a kind of steam booster of rocket propeller device.

Background technique

Launch vehicles such as existing rocket, guided missile, space shuttle all are to advance from the afterbody ejection with a large amount of high-temperature gases that propellant agent and liquid oxygen burning back produce, and its movement velocity and quality depend on the gas flow of ejection fully.Existing technology will increase the burning capacity that gas flow must increase propellant agent.Therefore, will inevitably consume a large amount of energy.

Summary of the invention

The objective of the invention is in order to overcome the shortcoming that above-mentioned prior art exists, provide a kind of and make full use of behind launch vehicle (as rocket, guided missile, the space shuttle etc.) engine combustion heat of the high-temperature gas high pressure water that gasifies rapidly, and produce the rocket propulsion assist device that a large amount of water vapors increases afterbody ejection gas flow.

The technological scheme taked of the present invention is for achieving the above object: this steam booster of rocket propeller device comprises rocket chamber, motor air jet pipe, jet outlet and liquid oxygen tank, motor air jet pipe top is the rocket chamber, liquid oxygen tank is positioned at the top of rocket chamber, and top, described rocket chamber also is provided with a steam booster device.

Described steam booster device is made of high pressure water vat, water vat piston, piston spring group, the mouth that sprays water with high pressure, high-pressure water pipe, valve switch, valve controling rod, thread switching control and metal ring, the water vat piston is housed in the high pressure water vat, and the water vat piston links to each other with top in the high pressure water vat by at least one group of piston spring group; The described mouth that sprays water with high pressure be evenly distributed be installed in the motor air jet pipe around, and with the motor air jet pipe in communicate, the mouth that sprays water with high pressure connects an end of high-pressure water pipe, the other end of high-pressure water pipe connects the bottom of high pressure water vat, and with the high pressure water vat in communicate; The described mouth that sprays water with high pressure is provided with valve switch, and valve controling rod is housed on the valve switch, and each valve controling rod links to each other with a metal ring by thread switching control.

The top of described high pressure water vat has at least one pore.

The present invention is by setting up a steam booster device between rocket chamber and liquid oxygen tank, when rocket chamber's ignition, during motor air jet pipe ejection high-temperature gas, steam booster device forms a large amount of steam to high temperature air jet water, and the throughput of jet outlet is increased rapidly.Therefore, the propellant agent of burning isodose can produce bigger propelling force.Not only energy saving but also can reduce pollution to environment particularly reduced greenhouse effect.

Fig. 1 is a steam booster of rocket propeller apparatus structure schematic representation of the present invention.

Embodiment

Steam booster of rocket propeller device of the present invention as shown in Figure 1 comprises rocket chamber 10, motor air jet pipe 12, jet outlet 14, oxygen case liquid 20 and steam booster device 21, a steam booster device 21 is installed between engine chamber 10 that has rocket now and liquid oxygen tank 20, this steam booster device 21 is by high pressure water vat 15, water vat piston 16, piston spring group 17, mouth 1 sprays water with high pressure, high-pressure water pipe 5, valve switch 2, valve controling rod 3, thread switching control 11 and metal ring 4 constitute, high pressure water vat 15 is fixedly mounted in the rocket afterbody, its capacity is determined by the specific requirement design, water vat piston 16 is housed in high pressure water vat 15, and water vat piston 16 links to each other with high pressure water vat 15 inner tops by at least one group of piston spring group 17 (quantity of piston spring group is set according to specific requirement).Have pore 19 in order to prevent water vat piston 16 vacuum to occur at the top of high pressure water vat 15.The mouth 1 that sprays water with high pressure distribute to be installed around motor air jet pipe 12, and with motor air jet pipe 12 in communicate, each mouth 1 that sprays water with high pressure connects an end of a high-pressure water pipe 5, the other end connect high pressure water vat 15 the bottom and with the high pressure water vat in communicate.The described mouth 1 that sprays water with high pressure is provided with valve switch 2, and valve controling rod 3 is housed on the valve switch 2, and each valve controling rod 3 links to each other with a metal ring 4 by thread switching control 11.

When rocket propulsion is worked, propellant agent pipeline 8 with the liquid oxygen of fuel in fuel nozzle 9 and the liquid oxygen tank 20 when pipeline 7 constantly sprays to rocket chamber 10 in from 6 beginnings of liquid oxygen nozzle, ignition simultaneously, produce a large amount of high-temperature gases after the propellant combustion, constantly spray from jet outlet 14 through motor air jet pipe 12, when high-temperature gas is flowed through motor air jet pipe 12, high-temperature gas blows all thread switching control 11 fusings, metal ring 4 comes off, all valve controling rod 3 resets immediately, valve switch 2 is opened, at this moment the water in the high pressure water vat 15 is subjected to water vat piston 16 under the effect of piston spring group 17, water in lower compression makes high pressure water vat 15 forms high pressure water and is vaporific ejection through high-pressure water pipe 5 from the mouth 1 that sprays water with high pressure in motor air jet pipe 12 at a high speed, mix with the high-temperature gas of the motor air jet pipe 12 of flowing through, form a large amount of steam to jet outlet 14 ejections.Because after steam turns to steam, volume increases doubly a lot, the jet in the same way outlet 14 of gas one that produces with combusting propellant sprays, gas flow through jet outlet 14 is increased, flow velocity increases, propellant agent at the burning isodose can produce bigger Driving force, finally reaches the purpose than a large amount of energy of original rocket saving and environmental protection.

Steam booster device of the present invention can apply to produce with combusting propellant the launch vehicle of gases such as rocket that gas is power, guided missile, space shuttle from the afterbody ejection.
