Development of bimetallic spinel catalysts for low-temperature decomposition of ammonium dinitramide monopropellants

Defence Technology, 2023
Ammonium dinitramide (ADN) based liquid monopropellants have been identified as environmentally benign substitutes for hydrazine monopropellant. However, new catalysts are to be developed for making ADN monopropellants cold-start capable.

An overview on properties, thermal decomposition, and combustion behavior of ADN and ADN based solid propellants

Defence Technology, 2018
Ammonium dinitramide [NH4N(NO2)2, ADN] is considered as a possible replacement for ammonium perchlorate (AP) in nearly all kind of solid rocket propulsions in the coming future. The reason to use ADN instead of AP in solid rocket propulsion is because of

Preparation of low hygroscopicity ADN-based energetic composite microspheres and their performance study

AIP Advances, 2023
In order to reduce the hygroscopicity of ammonium dinitramide (ADN), four different ADN/nitrocellulose (NC) samples were prepared from acetone solutions using electrostatic spraying, with the concentrations of 2.5, 5, 7.5, and 10 mg ml−1.

Advances in phase stabilization techniques of AN using KDN and other chemical compounds for preparing green oxidizers

Defence Technology, 2019
Research and development of green oxidizers and green fuels as a possible replacement for ammonium perchlorate (NH4ClO4, AP) and hydrazine (N2H4) respectively has been increased considerably in the recent years. AP and hydrazine are the oxidizer and fuel

Modelagem da combustão da dinitramida de amônio por simulação computacional Ammonium dinitramide combustion modeling by computational simulation

Química Nova, 2009
In this work, the combustion process of ammonium dinitramide, ADN, has been modeled in two different situations: decomposition in open environment, with abundant air and decomposition in a rocket motor internal environmental conditions.
