The EVB8 is a solenoid bi-stable valve designed to operate with different fluids, including cryogenic propellants. It ensures the function of bearing chill down valves for the turbo-pump of the Vinci engine and manage the propellant for the stage on the Ariane 6 launcher.
The engine EV box is made of 6 normally closed electro-valves providing a gas flow to the user when activated by an electrical command. It is a power-amplified device, composed of a power stage driven by a pilot stage, actuated by a redundant electrical solenoid.
The FLPP Hydrogen Chamber Valve (HCV) is an electrical poppet valve designed to work with gaseous hydrogen and driven by a brushless geared electrical motor. It has been successfully tested on the ETID engine demonstrator.
The FLPP Purge Valve is a propellant assisted solenoid bi-stable valve designed to operate with different fluids, including cryogenic propellants.
The Thrust Control Valve (TCV) is an electrically controlled regulation valve.
The Helium Filling Valve (VRE) is part of the liquid He subsystem (SSHeL) of Ariane 5 and Ariane 6 launchers. The main function of the VRE is to open on demand to allow a refill of the Helium tank.
The Helium Loading Plate composed of two electro-valves and two filters is positioned between the high-pressure helium vessels and the pressure regulator of the Ariane 6 upper stage.
The PPS®1350 Hall Effet plasma thruster draws on Safran Spacecraft Propulsion’ long experience with electric propulsion. It is designed for orbital transfer, stationkeeping and deorbiting satellites and other spacecraft. In particular, the PPS 1350 was the primary engine on ESA’s lunar probe, Smart-1, launched in 2003 by an Ariane 5 rocket. This mission was completed in September 2006.
The PPS®5000, produced by Safran Spacecraft Propulsion, is a Hall Effect Thruster purposely designed for “all-electric” satellites. It can operate in high-thrust or high specific impulse mode, and offers an operating lifespan of about 20,000 hours. This means it can handle orbital positioning and stationkeeping duties for a wide range of telecom and navigation satellites, as well as exploration spacecraft. The PPS®5000 was fully qualified in 2021.
The latest member of Safran Spacecraft Propulsion' Hall Effect plasma Thrusters, the PPS®X00 was designed to address the specific requirements inherent in the “New Space” market environment. With a lifespan exceeding 5,000 hours and very high specific impulse, the PPS®X00 is an extremely versatile thruster, making it ideal for all types of applications in its core market: low Earth orbit (LEO).
