Liquid Propellant Rocket Engines

Engines using liquid propellants are preferred in applications requiring long operating time, re-ignition or throttling. To assure propellant efficiency while maintaining low production costs of hardware, we are focussed on developing engines operating at medium pressure regimes (30 – 80 bar).


 Our development of low cost propulsion technology is based in the following principles:


- simplified design of rocket engines and turbo pump units

- low level operational parameter (chamber pressures, tem­peratures, RPM of turbo pump units)

- low cost materials and manufacturing technologies

- green, low cost and easily accessible propellants


Due to their world wide availability in combination with no or only minor toxicity, liquid oxygen (LOX) and ethanol (ethylalco­hol) or jet propellant (JP, ‘kerosene’) are our preferred systems. Handling is well proven in the course of many decades and does demand only moderate safety requirements.
