Amine-boranes: green hypergolic fuels with consistently low ignition delays.

Computationally Based Measures of Amine Azide Basicity and Their Correlation With Hypergolic Ignition Delays

Computationally Based Design and Screening of Hypergolic Multiamines

Seeking to identify structural features of saturated, (all) tertiary, alkyl multiamines (STAMs) that correlate with hypergolic ignition delays, conformers of STAMS whose ignition delays have been measured were established through density functional theory-based calculations. Examined from the standpoint of lone pair/(C-N and C-C) bond orientations, a correlation is suggested. Conformers of 1,3-...

A hypergolic bipropellant s consist of fuels and oxidizers that can ignite rapidly upon mixing without external ignition devices . This self –ignition technology makes the engine ignition more reliable with repeated use. Recently, ionic liquids with the dicyanamide anion which shown good hypergolic properties when contacted with common oxidizer such as concentrated nitric acid, were attracte...

Generation of melamine polymer condensates upon hypergolic ignition of dicyanamide ionic liquids.

Fuels that can be ignited chemically under ambient conditions—upon contact with an oxidizing agent—are referred to as hypergols. Engines powered by hypergols do not require electric ignition, thus making them simple, robust, and reliable alternatives to conventional fossil fuels. Commonly used hypergolic fuels include hydrazine and its methylated derivatives, which are extremely toxic, corrosiv...

Because of high toxicity of hydrazine and its derivatives, many efforts are conducted to finding alternative for hydrazine in hypergolic fuels which meanwhile can do spontaneous ignition, has a low environment risk. Due to high reducing ability of hydrazine, usage of powerful conducing agents’ idea was interested. These conducting agents required to improvement in order to use as a hyperg...
