摘要

One of the issues with the use of Electric Propulsionrn(EP) for satellites is that the satellite manufacturer hasrnto integrate the EP Propulsion system and the PointingrnMechanism from different suppliers so the resultingrnThruster Unit is not optimised for performance. RUAGrnSpace has recognised this situation and has beenrnworking with EDB FAKEL, one of the leadingrnsuppliers of EP Propulsion systems, to develop anrnIntegrated Thruster Module (ITM) that can utilise arnrange of EP Thruster combinations using a basicrnstructure that provides the thrust vector pointing, shockrnisolation and the thermal control of the EPrnsubassembly assembly on one integrated unit whichrncan be easily built into a satellite.rnRUAG Space has developed a Thruster PointingrnAssembly (TPA) that can currently support onernSPT140 Thruster or two SPT100 Thruster modules.rnThe TPA is based on a common lower structure with arntailored upper thruster support structure.rnDuring the development, breadboard tests werernundertaken to mitigate many of the risks that werernidentified.rnFollowing the breadboard testing, the design of thernTPA was updated and a QM model built for twornversions of the mechanism to support two SPT100 andrnone SPT140 Thrusters from EDB FAKEL.rnThe two QM models were based on a common lowerrnstructure but differed at the level of the Thrusterrnmounting, and with the support of the EP subsystem.rnTo achieve this, it was necessary to make compromisesrnduring the design process which also had a significantrnimpact on the final design of both mechanisms.rnThe QM TPA models have both been subjected to arnclassical qualification campaign which will include arnlife test on the complete system.rnThis paper will describe the impact that testing twornmechanisms using a common basic structure has on therndesign and the compromises that have to be made. Inrnaddition, an overview of the breadboard testingrnundertaken to mitigate the risks will be described andrnthe results briefly discussed.rnFinally, it will be shown in this paper how it is possiblernto qualify different versions of a mechanism using arncommon structure with add-on equipment to completerneach of the mechanism versions. The impact that thisrnapproach has on the test programme will also bernpresented.
