To enable the resupply of liquid helium users on orbit, the technology for helium transfer in space is being developed. A key element of the resupply process is the fluid acquisition in the supply dewar; feeding the liquid to the pump. For the Superfluid Helium On-Orbit Transfer (SHOOT) flight exper

โฆ Synopsis
Many future space programmes will utilize superfluid helium for thermal conditioning of system sensors. In order to extend mission life, it is necessary to provide a resupply capability. One of the major issues or concerns in the resupply process is the acquisition and delivery of the superfluid helium under tow gravity conditions. Because SFHe possesses unique characteristics and properties, current technology may not be applicable. Therefore, an experimental programme is being conducted to determine requirements for and operation of SFHe acquisition devices.

The general description, operation and design of a superfluid helium (SFHe) fluid acquisition system (FAS) for use under micro-gravity conditions is presented. For the type of FAS considered here, where fine-mesh woven screens are used to retain flowing SFHe within a gallery arm (flow) channel, thos
A forced flow superfluid helium circulation system has been developed. Steady state temperature distribution and transient thermal propagation behaviour along the cooling channel have been investigated. The results are analysed on the basis of the energy equation using the Gorter-Mellink relation. T
