A Study of a Low-Power Microwave Arcjet Thruster Using Ammonia Propellant
A low-power microwave arjet thruster was studied using ammonia gas as propellant. The purpose of the project was to generate ammonia plasma using a 7.5 GHz magnetron and a cylindrical cavity thruster, which is resonant in the TM001 mode [1]. The desired pressure was atmospheric or above while generating a thrust of roughly 20mN and an Isp of about 500s operating at low power (<100 kW). Introduc...
متن کاملDiode-laser tomography for arcjet plume reconstruction.
Diode-laser absorption tomography is described with which the spatial temperature and the atomic number density distribution of a 3-kW class arcjet can be derived simultaneously by reconstruction of the absorption coefficient field of the arcjet's argon exhaust plume. One can perform various parameter measurements by changing the arcjet's mass-flow rates and discharge currents. The maximum temp...
متن کاملHigh Power Flex-Propellant Arcjet Performance
A MW-class electrothermal arcjet based on a water-cooled, wall-stabilized, constricted arc discharge configuration was subjected to extensive performance testing using hydrogen and simulated ammonia propellants with the deliberate aim of advancing technology readiness level for potential space propulsion applications. The breadboard design incorporates alternating conductor/insulator wafers to ...
متن کاملDevelopment of Optical Diagnostics for Performance Evaluation of Arcjet Thrusters
This paper describes a detailed comparison of experimentally measured arcjet plume properties tomodel predictions. The experiments focus on the measurement of the exit plane vector velocity fieldand kinetic temperature by laser induced fluorescence. The model is based on a single-fluidmagnetohydrodynamic description of the flow. Reasonable agreement between model predictions and...
متن کاملAssessment of High-Power Electric Multi-Mode Spacecraft Propulsion Concepts
Multi-mode spacecraft propulsion systems utilizing a chemical monopropellant or bipropellant thruster and high-power electric Hall, arcjet, or pulsed inductive thruster were analyzed and compared in terms of mission capabilities. These systems are most effective compared to an all-chemical system when greater than 25% of the total delta-V is accomplished by the electric system due to the high m...
