Abstract
The utility model discloses an use lotion propellant feed device of solid propellant as power supply, including cylinder body, lotion propellant storage box, storage tank piston and propulsion piston, solid propellant has been pour to cylinder body bottom adherence, impels the piston to be located the cylinder body to with cylinder body inner wall sliding sealed fit, the storage tank piston is located lotion propellant storage box, and with lotion propellant storage box inner wall sliding sealed fit, impel piston and storage tank piston to pass through the transfer line connection, the transfer line is rather than the cylinder body that passes and lotion propellant storage box's end cover sliding fit. The utility model discloses a solid propellant stores safe and reliable, convenient to use as the power supply, and simple structure is compact, easily realizes microminiaturization, the during operation response is fast, and the action just can change the solid propellant dose and fire the face rapidly according to the supply demand to control promotes stroke and speed.
Description
Technical field
The invention belongs to rocket motor technical field, particularly a kind of take solid propellant as the pasty propellant supplier of power source.
Background technique
Gel/paste propellant agent, as novel propellant agent important focus in recent years, causes the great interest of various countries expert.Both this kind of propellant agent bonding solid propellant and liquid propellant advantage pasty propellant technology is the new concept propellant agent all greatly developed both at home and abroad in recent decades, and develop advanced lotion Push Technology thus, i.e. " dexterity " Push Technology (smart propulsion), pasty propellant both may be used for transport rocket, Satellite Attitude control, also may be used for missile weapon system, even civilian intelligent extinguishing device.The large advantage of pasty propellant one is under the prerequisite keeping high-energy-density, in very large range can regulate the mechanical property of propellant agent, as mobility, plasticity, viscosity, thixotropy etc.
Theory and practice all shows, by the appropriate design performance of propellant and rocket motor structure, under the cooperation of repeatedly ignition system and repeatedly shutdown systems, Novel cream rocket motor repeatedly can start as liquid rocket, in order to realize repeatedly starting, drive unit needs pasty propellant to extrude from tank, through flow control system and can relight device send into firing chamber.Therefore, drive unit is the important composition parts of lotion rocket motor.
In order to ensure that drive unit structure under the prerequisite of reliably working is optimized more, forefathers do a lot of work, according to current published document and patent, drive unit or be designed with two kinds: one utilizes hydraulic pressure installation to promote piston, extruded by pasty propellant from tank, through flow control system and can relight device send into firing chamber, its advantage is the pasty propellant working state that can meet large discharge, shortcoming also clearly, complex structure, device is heavier, and cost compare is high; Another kind is that pasty propellant is contained in cylindrical shape tank, extruded to enter in transparency window firing chamber by pasty propellant and burn, but this driving mode device is more complicated, wayward by Pneumatic extrusion and piston system.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, and working state safety, what can be applied to Pasty Propellant Rocket Engine reliably take solid propellant as the pasty propellant supplier of power source.
The technical solution realizing the object of the invention is:
Take solid propellant as a pasty propellant supplier for power source, comprise cylinder body, pasty propellant storage tank, storage tank piston and propelling piston; Cylinder base is adherent has built solid propellant, propelling piston is positioned at cylinder body, and coordinate with inboard wall of cylinder block slipper seal, storage tank piston is positioned at pasty propellant storage tank, and coordinate with the slipper seal of pasty propellant storage tank inwall, propelling piston is connected by drive link with storage tank piston, and the end cap of the cylinder body that drive link passes with it and pasty propellant storage tank is slidably matched.
The present invention compared with prior art, its remarkable advantage:
(1) the present invention adopts solid propellant as power source, and storage safe is reliable, easy to use.
(2) reasonable in design of the present invention, reliable operation, can meet the usage requirement of different condition, particularly aerospace field.
(3) the present invention is simple and compact for structure, is easy to realize microminaturization, and component can be obtained by simple machining, and connection and reasonable arrangement, takes up room little, is convenient to install.
(4) when the present invention works, response is fast, is swift in motion, and can changes solid propellant dose and combustion face according to demand and supply, thus controls to promote stroke and speed.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Accompanying drawing explanation
The structural representation of Fig. 1 to be the present invention with solid propellant be pasty propellant supplier of power source.
Embodiment
Composition graphs 1:
The present invention is a kind of take solid propellant as the pasty propellant supplier of power source, comprises cylinder body 1, pasty propellant storage tank 3, storage tank piston 5 and propelling piston 6; Adherently bottom cylinder body 1 build solid propellant 7, propelling piston 6 is positioned at cylinder body 1, and coordinate with the slipper seal of cylinder body 1 inwall, storage tank piston 5 is positioned at pasty propellant storage tank 3, and coordinate with the slipper seal of pasty propellant storage tank 3 inwall, propelling piston 6 is connected by drive link with storage tank piston 5, and the cylinder body 1 that drive link passes with it and the end cap of pasty propellant storage tank 3 are slidably matched.
End near propelling piston 6 moving direction on cylinder body 1 has exhaust port 2.
Exhaust port 2 is opened on the sidewall near propelling piston 6 moving direction end.
One end that propelling piston 6 is relative with storage tank piston 5 is provided with piston push rod, and two-piston push rod is connected by the internal and external threads cooperatively interacted.
Its working principle is:
During work, solid propellant 7 in cylinder body 1 is lighted, produce high temperature and high pressure gas, gas push propelling piston 6 travels forward, the air of cylinder body 1 the other end is discharged from exhaust port 2, simultaneously propelling piston 6 promotes storage tank piston 5 and travels forward, and under the extruding of storage tank piston 5, pasty propellant 4 propellant agent is extruded from storage tank 3.
