Tenders are invited for Electromechanical Multiline Thruster Switching Unit for Electric Propulsion (Artes at 4f.171)
Price Range 500 Keuro
design, manufacture and test a thruster switching unit facilitating the connection of multiple electric propulsion thrusters to one or more power processing units for redundancy or configuration purposes optimising the system architecture.Targeted Improvements: - Improved efficiency (10% increase with respect to solid state solution).- Increased reliability with respect to a relay-based solution.- Reduced level of complexity on system-/equipment level.- Lead time reduction/time tomanufacture and test by 30%.Description: Nowadays relatively complex high voltage switching units are used for electric propulsion applications, with some difficulties to procure critical key components.In electric propulsion systems, cross-switching of a high voltage is required due to the reliability/redundancy requirements (switching between main/redundant), the reconfigurability (switching high voltage converters between station keeping and orbit raising) or thrust vectoring. For lower voltage levels Hall Effect Thrusters (HET) conventional relays are currently a suitable technical solution, although it is rather complex with demands in mass andsize. However, for higher voltages including high specific impulse HET (or such operating in dual mode), ion engines relays become a significant challenge
