Item Nitrous Oxide Boiler Development for the Dream Chaser® Spacecraft Thermal Control System(44th International Conference on Environmental Systems, 2014-07-13) Metts, Jonathan G.; Miller, Stephen W.; Johnson, Jeff; Quinn, GregoryThe Dream Chaser® human spacecraft utilizes excess nitrous oxide propulsion oxidizer as an evaporant to provide heat rejection for the vehicle’s Active Thermal Control System. This capability is provided by a nitrous oxide boiler, currently in development. Performance analysis and test results indicate that a heat exchanger boiling nitrous oxide with a propylene glycol/water coolant fluid can provide the required heat rejection for Dream Chaser while preventing freezing or incomplete phase transition in the boiler unit. Integration of nitrous oxide boiler technology will result in a net system mass savings.
