Effects of Aniline Impurities on Monopropellant Hydrazine Thruster Performance
Journal of Spacecraft and Rockets, 1976Both a 0.45-N and a 0.9-N thruster representative of the designs being flown on 3-axis stabilized spacecraft were used in testing various grades of hydrazine for the phenomenon of monopropellant hydrazine thruster catalyst bed poisoning. Both designs employed Shell 405 ABSG spontaneous catalyst. It is found that pulse shape distortion can be minimized,

Simulation Model for Catalytic Monopropellant Hydrazine Thrusters
IFAC Proceedings Volumes, 1992Abstract Hydrazine thrusters are often used as actuators for spacecraft attitude and orbit control systems, for example for the missions of METEOSAT, OTS, INTELSAT and GIOTTO. The reason is that hydrazine requires less hardware than other propellants, and thrusters with thrust levels down to 0.5 N with reproducible minimum impulse bit down to 0.005 N

Testing and Characterization of a Hydrogen Peroxide Monopropellant Thruster
Journal of Propulsion and Power, 2008In the present paper, the use of advanced catalytic beds on ceramic supports as a cost-effective alternative to metal screen reactors for the decomposition of high-concentration hydrogen peroxide in small monopropellant rockets is investigated. For this purpose, a reconfigurable test bench for the characterization of the operation and the propulsive ...

Conceptual Design of Small-Sized Thruster Using Laser Ignition of High-Energy Monopropellant
Journal of Propulsion and Power, 2023Ammonium dinitramide (ADN)-based energetic ionic liquid propellants (ADN-EILPs) present considerable potential as monopropellants due to high energy density, high thermal/chemical stability, and low toxicity.

Verification of Contamination Predictions for Monopropellant Thrusters
1977Abstract : This paper represents the major results and conclusions of an AFRPL in-house analysis program set up to verify the capabilities of the monopropellant option of the CONTAM computer code for predicting plume contamination on sensitive spacecraft surfaces. The data used for verification was acquired in an AFRPL sponsored program at JPL. In that

Development and Test of a Miniature Hydrogen Peroxide Monopropellant Thruster
42nd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2006Analysis of present and future missions concluded that a miniaturised hydrogen peroxide monopropellant rocket engine is the optimum solution for the increasing demand for small and low cost propulsion systems for small satellites. The attractiveness of monopropellant thrusters is based on its operational and structural simplicity.
