Description

Background Art

[0001] Solid electrolyte electronically controlled propellant, also called electronically controlled solid propellant or solid electronically controlled propellant, has overturned the working mode of traditional solid engines and is a new direction in the field of solid propulsion technology. Electronically controlled solid engines are expected to achieve multiple starts and random control of thrust size. When applied to the power unit of missile weapons, they can effectively improve the maneuverability of missiles. At the same time, they have good application prospects in the fields of micro-propulsion and space propulsion, and can effectively improve the attitude and orbit control capabilities of spacecraft.

[0002] The propellant in the solid electrolyte electronically controlled propellant grain has the characteristics of a solid electrolyte. Electrodes are arranged in the grain. After power is turned on, the solid electrolyte propellant undergoes electrolysis to generate a great deal of heat, and the grain is ignited. After power is turned off, the grain is extinguished. The burning rate of the solid electronically controlled propellant can also be controlled by adjusting the voltage, realizing active control of the solid propellant combustion process, so that the solid propellant engine has multiple start-up and thrust adjustable functions, while retaining the inherent advantages of the solid propellant engine. The emergence of solid electrolyte electronically controlled propellants enables solid propellant engines to retain their advantages of simple structure and convenient use, while also realizing multiple start-up and thrust adjustment functions. In addition, the solid electrolyte electronically controlled propellant has high safety performance and significant insensitivity characteristics. When subjected to external stimuli such as heat and impact, it does not produce any violent response and is easy to store. The existing preparation method of solid electrolyte electronically controlled propellant usually first shapes a single or array of electrode materials, and then composites the propellant and the electrode materials by casting; or by casting, the propellant and the single or array of electrode materials are cast and composited at the same time. However, the above preparation methods are usually cumbersome and the preparation process is complicated. It is also difficult to flexibly control the structure and size of the drug column.

[0003] When direct current is used for ignition, the electrode at the burning end should be connected to the positive electrode of the power supply, and the burning end of the propellant should have a large current density, which can effectively improve the ignition performance of the solid electrolyte electronically controlled propellant. After the power is cut off, the electrolysis reaction stops, and after all the electrolyzed products are burned, the propellant automatically extinguishes. However, the current electronically controlled propellant material generally uses solid hydroxylamine nitrate gel. When the solid propellant is loaded with a whole piece of gel, the gel is easily heated and thinned and flows down due to the increase in temperature during the combustion process, resulting in incomplete combustion.

[0004] The fundamental reason why solid electrolyte electric propellant combustion is controllable is that the generation of electrolysis products can be controlled by voltage, and the factors that affect the electrolysis reaction of solid electrolyte electric propellant are mainly current density, electrode shape, electrode spacing, contact area and electrode material. At present, the electrode control methods of electric propellant mainly include end burning electrode and core burning electrode (concentric axis electrode). However, the spring and other thrust-type clearance fits used in the end burning electrode will directly lead to poor contact of the grain and control failure; after the core burning electrode burns a certain thickness, there will be a gap between the inner electrode and the grain, resulting in contact failure between the grain and the inner electrode, which cannot be realized in large-scale and is only suitable for micro-thrusters. Reasonable structure of solid electrolyte electric propellant matrix and electrode material can greatly improve the performance of solid electrolyte electric propellant. How to rationalize the structure is a research hotspot of solid electrolyte electric propellant.

[0005] Solid electrolyte electronically controlled propellant engines are particularly suitable for power plants of small aircraft, and relevant projects have been carried out for demonstration and verification. Once this technology is successful on small devices, it will inevitably promote its transformation and application to large devices, and comprehensively expand the utility of the technology. However, there is still little exploration of the practicality of this technology on large devices, and further in-depth research is needed. For example, in small devices, the size of the propellant grain is limited, and a single electrode can effectively control the entire propellant grain to achieve electronically controlled combustion. However, for large solid engines, the propellant grain size is large, and a single built-in electrode obviously cannot fully control the entire propellant grain. How to design and manufacture the engine to achieve good electronically controlled combustion still has technical difficulties. Summary of the invention

[0030] A solid electrolyte electrically controlled energetic charge described in the present invention is prepared by the above-mentioned method for preparing the solid electrolyte electrically controlled energetic charge. The solid electrolyte electrically controlled energetic charge is in the shape of a scroll and includes a solid electrolyte electrically controlled propellant layer, a negative electrode material, a solid electrolyte electrically controlled propellant layer, an insulating layer film, a positive electrode material and an insulating layer film that are sequentially wound and stacked. The surface of the positive electrode material is not covered by an insulating layer at one end of the scroll-shaped solid electrolyte electrically controlled energetic charge, so that the positive electrode material is in direct contact with the solid electrolyte electrically controlled propellant layer at this end. When the scroll-shaped solid electrolyte electrically controlled energetic charge is connected to a DC power supply, an end where the positive electrode material and the negative electrode material are in direct contact with the solid electrolyte electrically controlled propellant layer will produce an electrically controlled fire. As the combustion continues, the insulating layer material of the rear section is ablated and yields, and the positive electrode material covered by the insulating layer leaks out, thereby gradually controlling the combustion of the rear section propellant. Through the yielding of the insulating layer and the control of the DC power supply, the entire scroll-shaped solid electrolyte electrically controlled energetic charge is burned in a specified direction.

Further, the thickness of the negative and positive electrode materials and the solid electrolyte electric-controlled propellant should be determined according to the size of the entire scroll-shaped solid electrolyte electric-controlled energetic charge. When the size of the prepared propellant charge is large, the thickness of the negative and positive electrode materials and the solid electrolyte electric-controlled propellant can be appropriately thickened; when the size of the prepared propellant charge is small, the thickness of the negative and positive electrode materials and the solid electrolyte electric-controlled propellant can be reduced as much as possible. Further, when the electrode material does not act as a reducing agent (that is, the electrode material is not consumed as the combustion proceeds), the thickness of the solid electrolyte electric-controlled propellant layer can be thickened as much as possible, thereby improving the mass ratio of the thruster charge.

[0032] Beneficial effects of the present invention:

[0033] The present invention can realize repeated ignition and extinguishing by switching on and off the power supply, and can change the magnitude of the applied voltage, thereby changing the thrust, while eliminating the traditional supply spring supply structure and improving the combustion stability.

[0034] Compared with the traditional solid powder column method of using a whole block of gel to charge the powder, the electrode of the present invention wraps the solid electrolyte electric-controlled propellant matrix with each other, strictly controls the thickness of the solid electrolyte electric-controlled propellant layer, and reduces the flow phenomenon during the combustion process.

[0035] The processing method of the present invention is simple, and the overall arrangement of the solid electrolyte electrically controlled energetic charge can be optimized by changing the negative and positive electrode materials and the thickness of the solid electrolyte electrically controlled propellant layer. At the same time, the size of the charge can be controlled by increasing the number of winding turns, thereby adapting to the corresponding thruster and engine.

[0036] Compared with coaxial or array electrodes, the electrode layout of the present invention is more reasonable. The electrode material and the solid electrolyte electric-controlled propellant are wrapped with each other by winding, which increases the effective area for current to pass through, has more and more uniform combustion areas, and thus provides greater thrust. In addition, the mass ratio of the thruster charge can be effectively improved by increasing the thickness of the solid electrolyte electric-controlled propellant layer or reducing the thickness of the electrode material.
