Embodiment Construction

[0042] The following specific examples illustrate the implementation of the present invention. Those familiar with this technology can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention. , Not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0043] The high temperature during the combustion of the propellant will cause the collapse and sintering of the catalytic bed structure and the deactivation of active components, which directly affects the normal operation of the thruster. The common preheating system for ignition requires additional heating power, so the ignition method is relatively simple.

[0044] In order to solve the above problems, the p...

Abstract

The embodiment of the invention discloses an ADN based single-component thruster adopting low-temperature plasma concerted catalysis. The ADN based single-component thruster comprises a spouting section, an ionization section, a catalysis section and a combustion chamber which are coaxially connected sequentially, wherein the two ends of the spouting section and the two ends of the ionization section are pressed by a front flange plate and a middle flange plate; an integrated structure formed by the catalysis section and the combustion chamber and the ionization section are pressed by the middle flange plate and a rear flange plate; the spouting section comprises the front flange plate, a front insulator and an anode chassis as well as gas and liquid supply tubes separately used for providing an ADN liquid propellant and gas; the ionization section comprises a cylindrical anode, a middle insulator, a barrel-shaped cathode, a rear insulator and the middle flange plate which are sequentially connected to the anode chassis; the middle flange plate and the front flange plate are matched and pressed through a locking bolt; the catalysis section comprises a rear flange plate and a catalysis bed; and the combustion chamber comprises an optical test window and a reserved sensor jointing base. The AND based single-component thruster has various ignition ways, and is of great significance in completely converting an existing catalysis dissociation ignition way.

Description

Technical field [0001] The embodiment of the present invention relates to the technical fields of space chemical propulsion technology and electric thruster design, in particular to an ADN-based single-component thruster with low-temperature plasma cooperative catalysis. Background technique [0002] Ammonium Dinitramide (ADN) thruster is a propulsion technology with great development potential. ADN-based propellant is composed of ammonium dinitramide, fuel and water. It has low toxicity, no pollution, low freezing point and stability. The advantages of high performance and low volatility are a new development direction and research hotspot of space technology, which has a wide range of application prospects. Compared with the traditional propellant anhydrous hydrazine, the unique advantages of ADN-based propellants make it unnecessary for special protective measures in the development process, and can realize the pre-package of the space power system, which greatly improves the ...
