Tasks of the Propellants Department
Besides the regular requirements to future propulsion systems, like increased thrust, specific impulse, flight range, speed and reliability, prospective propellants must be environmentally friendly, cost-effective and easy to use.
Satellite propulsions are still operated with liquid fuels, like dinitrogen tetroxide, hydrazine, mono-methyl hydrazine (MMH), asymmetric dimethyl hydrazine (ADMH); they are toxic but storable for extremely long periods and ensure stable propulsion features.
Gelled propellants are produced from liquid fuels and gelling agents. Once in a tank, i.e. in idle state, they change from solid into liquid state when shear stress is applied. This particular feature provides a combination of major advantages to gelled propellants for use in liquid and solid propellants.
