Anti‐hygroscopicity technologies for ammonium dinitramide: A review**

open access: yesPropellants, Explosives, Pyrotechnics, Volume 48, Issue 5, May 2023., 2023
Abstract Valuable propellants have the characteristics of high impulse, low pollution, and strong stability, and oxidizers play a substantial role in determining the performance of propellants. Ammonium dinitramide (ADN) is a relatively promising oxidizer due to its high‐energy and chlorine‐free characteristics.

Combustion Wave Structure of the Ammonium Dinitramide‐Based Ionic Liquid Propellant

open access: yesPropellants, Explosives, Pyrotechnics, Volume 48, Issue 2, February 2023., 2023
Abstract The ammonium dinitramide‐based ionic liquid propellant (ADN‐based ILP), which is a mixture of ADN, monomethylamine nitrate (MMAN), and urea, is a low toxic monopropellant with a higher performance than that of hydrazine. To clarify the combustion wave structure of ADN‐based ILP, which has low volatility, we focused on the relationship between ...

ADN Solid Propellants with High Burning Rates as Booster Material for Hypersonic Applications

open access: yesPropellants, Explosives, Pyrotechnics, Volume 47, Issue 7, July 2022., 2022
Abstract RAM‐ and SCRAM‐Jet engines can not generate static thrust and only work at high speeds. This starting velocity of the motor v0 is usually generated by carrier rockets or boosters, which mostly use solid propellants based on ammonium perchlorate (AP) and hydroxyl‐terminated polybutadiene (HTPB).

4‐Amino‐1‐Butyl‐1,2,4‐Triazolium Dinitramide – Synthesis, Characterization and Combustion of a Low‐Temperature Dinitramide‐Based Energetic Ionic Liquid (EIL)

open access: yesPropellants, Explosives, Pyrotechnics, Volume 47, Issue 7, July 2022., 2022
Abstract Salts being liquid below 100 °C are defined as ionic liquids. Due to their unique properties, they are attracting increasing interest and are also being investigated in the field of energetic materials. Combining nitrogen‐rich cations and oxygen‐rich anions, it is possible to obtain energetic ionic liquids (EILs).

Thermal Decomposition, Ignition Process and Combustion Behavior of Nitrate Ester Plasticized Polyether Propellant at 0.1–3.0 MPa

open access: yesInternational Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022
Nitrate ester plasticized polyether (NEPE) propellant is widely used in solid rocket motors, having both good mechanical properties and high specific impulse. However, its ignition and combustion process are complex and need to be better understood.

Thermal Behavior and Micro Structure of TKX‐50

open access: yesPropellants, Explosives, Pyrotechnics, Volume 46, Issue 2, Page 262-266, February 2021., 2021
Abstract The thermal behaviour of TKX‐50 was reinvestigated in an extended temperature range by means of temperature resolved X‐ray diffraction. TKX‐50, synthesized at the Fraunhofer ICT, was identified using Rietveld‐analysis and reference data from the CCDC.

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

open access: yesDefence 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

open access: yesDefence 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
