OUR PROJECTS

PCFS/EPCS – Propellant Conditioning Systems

  • Provided customized design, analysis, & fabrication of complex cryogenic test systems used for precision temperature control of cryogenic propellants at specific pressure & flow ranges. This includes both cryogenic gases as well as sub-cooled liquids (GO2, LO2, and LCH4)

C7VS – Cryogenic Insulation Calorimeter

  • Provided customized design & analysis of state-of-the-art, large-scale calorimeter to measure the effectiveness of multi-layer insulation (MLI) packages at specific, precisely-controlled cryogenic temperatures

INP1 – Undersea Fuel Cell Power Systems

  • Developed the capability to provide gaseous oxygen & hydrogen via controlled vaporization of ultrapure cryogenic liquid in dewars. Testing was conducted at SLI’s Hydrogen Test Facility which allowed LOX and LH2 dewars to be refilled

LZBO – Liquid Oxygen Zero Boil-off Storage

  • Developed a liquid oxygen thermal management test system that was the first to achieve zero boil-off, using LN2 in place of LOX, in tests at NASA GRC’s SMIRF
