Evaluation of a High‐Performance Monopropellant Formed of Microencapsulated Hydrocarbon Fuels in Combination With Gelled Hydrogen Peroxide in a Strand Burner Setup

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 5, Page 781-789, May 2026.
A high‐performance premixed monopropellant is prepared from hydrocarbon‐filled microcapsules and hydrogen peroxide. This propellant is burned in a strand burner, and the effect of different parameters on the burn rate is evaluated. ABSTRACT A dispersion of hydrocarbon‐fuel‐filled microcapsules in gelled hydrogen peroxide can form a premixed ...

Thermal Ignition of ADN‐Based Propellants

Propellants, Explosives, Pyrotechnics, Volume 44, Issue 9, Page 1096-1106, September 2019., 2019
Abstract Ammonium dinitramide (ADN, NH4+ N(NO2)2−) based monopropellants are extremely promising as hydrazine replacement. Thermal igniters are attractive for ADN thrusters as they allow a more prompt ignition and may be better suited for larger engines (100‐500 N) compared to the currently used preheated catalysts.
