An Airborne Cyrogenic System for Pneumatic Power Generation, Cooling, and Other Uses

Abstract

This paper describes an airborne cryogenic system for pneumatic power generation which has been developed and constructed by Sundstrand-Turbo. This system maintains a gas storage bottle at 3000 psi upon demand by pumping stored liquid nitrogen from a vacuum jacketed container. The pump is a small high pressure multi-piston type driven by a turbine utilizing the 3000 psi stored gas supply. Figure 1 shows a picture of this system which will be described more fully. The system shown has a storage capacity of 20 liters, 36 pounds of liquid, and will deliver approximately 6 pounds per minute of nitrogen gas.
