In this paper, an overview is presented of the latest developments of space cryocoolers at Thales Cryogenics B.V. Planned future developments for the LPT6510 cooler are presented, and the synergies between Commercial-off-the-shelf (COTS) and space are reviewed, such as design principles from space coolers being applied to an upgraded variant of the COTS LPT9310, as well as design principles from COTS coolers being applied to the LPT6510 for improved manufacturability.
Thales performed a simulation and experimental study into the coupling of an off-the-shelf pulse tube to a designed-for-space, high-performance compressor, and a prediction is given regarding what performances could potentially be achieved with an optimized design.
