ADN based single-component thruster adopting low-temperature plasma concerted catalysis

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...
