Title: Zero Leakage Rotary Union for Gaseous Cryogen Transport
Agency / Branch: DOD / NAVY
Contract: N65538-10-C-0055
Award Amount: $79,962.00


Advances in naval weapon and propulsion technology are requiring large increases in power production. New technologies to meet these greater power demands has lead to advanced high speed, high power density electrical generators on-board naval vessels, which require active cooling of generator components. A significant problem experienced in the use of new generator technology is the transport of a coolant medium to the rotating portion of the generator. Existing commercially available rotary unions do not meet the stringent requirements for use on-board naval vessels. Mainstream proposes an innovative concept to meet these requirements. In Phase I, specific component calculations, selection, and evaluation will seek to identify and mitigate all deficiencies before prototype construction. Once detailed selection of all system components is complete, Mainstream will build and experimentally test the rotary union concept in a relevant environment (TRL 5). In Phase II, Mainstream will continue development of second generation concepts, field test prototypes in operational situations, and prepare the rotary union for commercialization.
