Thermal Management Challenges For Future Military Aircraft Power Systems

A closed-cycle gas turbine is a turbine that uses a gas (e.g. air, nitrogen, helium, argon, etc.) for the working fluid as part of a closed thermodynamic system. Heat is supplied from an external source. Such recirculating turbines follow the Brayton cycle. WebNov 2, 2004 · Typically an open cycle system will be considerably lighter than a closed cycle system, except when run times are lengthy. Coolant requirements for an open thermal management system, for a pulsed power source with a 30% duty cycle with an average heat load of 2.9 MW, ranged from 2007 kg of ammonia or 1127 kg of water. soil shear
