Abstract: A method for nitrous decomposition can include: expanding liquid nitrous into gaseous nitrous in a decomposition chamber; injecting heated nitrogen gas into the decomposition chamber so as to mix with the gaseous nitrous, wherein the heated nitrogen gas is at a nitrous decomposition temperature; heating the gaseous nitrous with the heated nitrogen gas to the nitrous decomposition temperature; and decomposing the gaseous nitrous into nitrogen and oxygen. The method can include: heating the nitrogen to at least the nitrous decomposition temperature; heating the liquid nitrous prior to expansion into the decomposition chamber; and performing the decomposition without a catalyst or heating element in the decomposition chamber. A swirling device can be positioned at an inlet to the decomposition chamber. A swirling nozzle can be positioned at an inlet to the decomposition chamber.
