Green Propellants Based on Ammonium Dinitramide (ADN)

, 2011
Ammonium perchlorate (AP) and hydrazine are today widely used as propellants. AP as oxidizer in solid propellants and hydrazine as liquid monopropellant (Brown, 1995; Sutton and Biblarz, 2001). These propellants are well known for their good performance characteristics, but their limitations and liabilities regarding toxicity, operational handling and ...

Boosting Decomposition and Combustion of TKX‐50 and HTPB/TKX‐50 Propellants With NH2‐MIL‐88B(Fe) MOF

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Dihydroxylammonium 5,5′‐bistetrazole‐1,1′‐diolate (TKX‐50) is a promising energetic material that possesses both exceptional energy density and low sensitivity. Nevertheless, its application is hindered by incomplete pyrolysis during combustion or explosion. Various strategies, including eutectic formation, composite preparation, and catalysis,

Development of NMP‐001, A Nitromethane‐Based Green Propellant

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1269-1276, August 2026.
ABSTRACT This paper discusses the development of a model monopropellant that is aimed at exploring the applicability of nitromethane‐based propellants as an alternative to hydrazine. This approach addresses the challenges faced by HAN‐, ADN‐based propulsion by being more cost‐effective while providing similar performance figures.

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1224-1234, August 2026.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.
