Embodiment Construction

[0042] The implementation mode of the present invention is illustrated by specific specific examples below, and those who are familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this description. Obviously, the described embodiments are a part of the present invention. , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

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

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] Embodiments of the present invention relate to the technical fields of space chemical propulsion technology and electric thruster design, and specifically relate to an ADN-based single-element thruster with low-temperature plasma synergistic catalysis. Background technique [0002] Ammonium Dinitramide (ADN) thruster is a propulsion technology with great development potential. The ADN-based propellant is composed of ammonium dinitramide, fuel and water, and has low toxicity, no pollution, low freezing point, and stability. It is a new development direction and research hotspot of space technology, and has broad application prospects. Compared with the traditional propellant anhydrous hydrazine, the unique advantages of ADN-based propellants make it unnecessary for special protective measures during the research and development process, and can realize the pre-packaging of space power systems, greatly improving the system's rapid response capability and...
