For over 40 years, our bipropellant thrusters have been used for a diverse range of mission, including attitude, trajectory, manoeuvring and orbit control of large satellites and spacecraft, deep space probes and the apogee orbit injection of geostationary satellites.
Our standard off-the-shelf range includes the 10 N and 200N thruster. Larger versions include 400N apogee motor. The 'work horse' thruster specified for most applications is the 10 N model.
The 200N thruster was developed for the Automated Transfer Vehicle where it performed flawlessly throughout its space station resupply missions from 2008 to 2014. Currently, It has been selected to fly in the Orion Multi Purpose Crew Vehicle (MPCV).
Our complete range of bipropellant thrusters have their combustion chamber and nozzle throat manufactured from a heat and oxidation resistant platinum alloy. This enables longer life and higher operating temperatures to maximise thruster performance. In addition, the use of this alloy avoids the need for surface coatings. The uncoated surfaces are absolutely resistant against oxidation and are invulnerable to the use of test sensors and pulse mode cycling.
All bipropellant thrusters are provided with trimming orifices upstream of the propellant control valves. This feature allows for individual adjustment of the propellant flow rate according to the systems design pressure.
Our bipropellant thrusters are available in at least two variant types to more closely match the specified application and customer requirements. For example, a choice of two types of flow control valve:
Both of the above thruster types have identical performance.
Our bipropellant engines and thrusters are designed and tailored to fulfill all the requirements for orbital
satellites or deep space probes, including orbit injection and all manoeuvres required to maintain a stable orbit
and attitude throughout the spacecraft's operating service life.
We supply from thruster component level and thrusters through to heat shields, support structure kits and complete propulsion systems for satellites, spacecraft, orbital platforms, interplanetary probes, deep space missions and man-rated systems.
We produce over 200 thrusters per year for international spacecraft and satellite propulsion systems. Thrusters in high demand are economically produced on a serial like production and are therefore readily available, subject to customer specific requirements. Thrusters with less demand are made to order.
