The Decomposition of a Hot Monopropellant in an Inert Atmosphere
Combustion Science and Technology, 1976Abstract —The title problem for a spherical droplet is considered when the activation energy is large. Asymptotic solutions are obtained which, when heat is gained from the atmosphere, describe a monotonic increase of the burning rate M as the Damkohler number D increases from 0 to ∞.

A comparison of solid monopropellant combustion and modeling
35th Aerospace Sciences Meeting and Exhibit, 1997Many of the ingredients in solid propellants burn as monopropellants. This paper focuses on the combustion characteristics of three typical monopropellants, AP, RDX and HMX. Monopropellant modeling efforts are reviewed. Early models describing monopropellants were primarily based on global kinetics.

Theory of the burning of monopropellant droplets
Combustion and Flame, 1959Abstract The steady-state burning of a single liquid monopropellant droplet in an infinite inert atmosphere is considered in detail, including allowances for thermal conduction, diffusion and chemical kinetic effects. Simplified forms of the governing equations are developed, and theoretical predictions compared with experimental results.

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

The theory of burning of monopropellant droplets in an atmosphere of inerts☆
Combustion and Flame, 1963Abstract The present paper deals with the theory of the burning of monopropellant droplets in an atmosphere of inert gas which may be either hotter or cooler than the adiabatic decomposition products of the monopropellant. Numerical and approximate solutions to the equations are obtained.

THE IGNITION AND COMBUSTION OF A LIQUID MONOPROPELLANT
1967Abstract : An investigation was made of the heat-up, ignition and combustion of a nitrate ester monopropellant droplet when suddenly placed in a high temperature gas. At moderate pressures a combustion zone became noticeably developed as the droplet approached its wet bulb temperature and a steady burning period followed.

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
