Abstract

The dewar described in this paper was developed and fabricated under contract to Grumman Aircraft Engineering Corporation for use on the Apollo Lunar Excursion Module Program. Supercritical helium is stored on board the LEM spacecraft and is used to pressurize the storable propellant tanks. The dewar provides helium for the cool-down and initial fill of the spacecraft helium tank. It also supplies liquid helium to an associated helium conditioning unit which provides for final fill of the spacecraft tank at 9.7°R and at pressures from 35–500 psig. The block diagram shown in Fig. 1 shows the purpose for which the dewar was designed.
