Helium Storage at High Density and Discharge at High Flow Rates

Part of the Advances in Cryogenic Engineering book series (ACRE, volume 23)


The Air Force Weapons Laboratory requires bulk storage and discharge of cryogenic helium at densities approaching 0.2 × 103 kg/m3 (12.5 lb/ft3) and pulsed flow rates of several kg/s—conditions significantly in excess of previous applications. By comparison, the Apollo Lunar Module Helium Storage System has a fill density of 0.13 × 103 kg/m3 (8.1 lb/ft3) and a discharge rate of 0.04 kg/sec (0.09 lb/sec) [1]. In order to demonstrate the practical feasibility of a system meeting these requirements, the NBS Cryogenics Division was asked to design, build, and demonstrate a system to: (1) store helium in a dewar at a density approaching 0.2 × 103kg/m3 with a pressure less than 10.3 MPa; (2) discharge helium in pulses of 2 sec or more and at a flow rate of at least 1.0 kg/sec at greater than 3.5 MPa pressure.
