Pulsed Chemical Rocket with Green High Performance Propellants

49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2013
PulCheR (Pulsed Chemical Rocket with Green High Performance Propellants) is a new propulsion concept in which the propellants are fed in the combustion chamber at low pressure and the thrust is generated by means of high frequency pulses, reproducing the defence mechanism of a notable insect: the bombardier beetle.

Ammonium Dinitramide (ADN) Decomposition as Green Propellant

Thermal decomposition of eco-friendly propellants such us ammonium dinitramide (ADN) aims to replace hydrazine in satellite systems. ADN, with formula [NH4]+[N(NO2)2]−, is a promising high-performance rocket propellant. It decomposes cleanly, producing gases such as NH3, H2O, NO, N2O, NO2, HONO, and HNO3, making it an attractive alternative to ammonium

Green plasticizers for multibase gun propellants (Lecture)

2007
TNO Defence, Security and Safety has a long history of research on gun propellants. Areas investigated are formulating (new ingredients, optimization), manufacturing, charge design and lifetime assessment [1,2,3,4,5]. In conventional propellants inert plasticizers are used to alter performance, processability or barrel erosion. Widely used plasticizers
