Semi-Active Side-Lateral Engine Mounts for Control of Vibration and Shock Loading

Requirements for oxygen production aboard aircraft carriers are changing. As more aircraft are converted to OBOGS, the need for liquid oxygen is decreasing. However, LOX requirements are not expected to drop to zero for a decade or more. For the nextdecade, there is a clear need for a flexible, compact system to produce LOX in small quantities. Mesoscopic Devices proposes to develop a compact gaseous and liquid oxygen production system using both gas-phase and cryogenic separation to yield ahigh-purity oxygen stream in a compact, modular system that can be baselined into new ships or retrofitted to existing ships. Our baseline design uses an innovative large-capacity pulse tube liquefier and high performance compact heat exchangers to yieldhigh efficiency and long life. With no moving parts at the cold end, the system is tolerant of shock and vibration loads. The system can be configured to produce liquid and gaseous oxygen in any combination and is scalable to meet future needs. In Phase I,we will identify the most promising separation approach, define the optimum system configuration, and design the baseline system. In Phase II, we will build and test a complete oxygen production system.
