200 N Bipropellant Thruster


For over 40 years, our bipropellant thrusters have been used in a diverse range of missions, including boost and on-orbit maneuvering of geostationary satellites and deep space probes. The provided thrust ranges from 4N up to 400N.

The 200N thruster was developed for the Automated Transfer Vehicle (ATV) where it demonstrated flawlessly its performance on several missions.

It has been selected to fly in the future Multi Purpose Crew Vehicle (MPCV). Based on our design heritage of coaxial injection systems and uncoated combustion chambers, our portfolio is evolving with the 4N and 22N thrusters to fulfill new requirements from commercial and institutional missions.

The 200N bipropellant engine was developed and qualified for application as attitude control, maneuvering and braking thruster of ESA‘s ATV. The engine is designed to be capable of both steady-state and pulse mode in a very broad regimes of inlet conditions and exhibits outstanding thermal and combustion stability even at extreme conditions. To meet the specific FDIR needs of man rated missions, the engine is equipped with several flight temperature sensors for e.g. in-flight leak detection and a combustion pressure transducer.
