DACTEM Research & Development team worked tirelessly to design and build a state of the art precision mechanism instrument to measure the thrust of a satellite plasmic propulsion engine.
With its long experience of design for instruments operating in spatial thermal vacuum, DACTEM has responded to the challenge of designing within the demanding range and precision required but also the long term thermal stability requested by the customer.
Innovative design with unmatched performance
Through innovative design in passive thermal management, in electromagnetics for the voice-coil actuator and on-board calibration device, combined with a thorough kinetic response study, DACTEM demonstrated that the mechanism was capable of exceeding the required performance, notably reliably measuring engine thrust with a precision of a fraction of a mN (equivalent to the weight of a very short human hair), giving its customer the confidence to launch the manufacturing phase which is the next step of the program.
“Our team has worked tirelessly on this project, particularly as most of the design work was carried out during the covid 19 confinement period. This demonstrates our multidisciplinary team ability to manage and design collaboratively project, even as elaborate as this one.” says Emmanuel POULEAU, DACTEM Managing Director.
