Abstract
A thermal system includes a tank storing a cooling fluid in a liquid state and a gas state, a first heat exchanger releasing heat into the tank, a second heat exchanger fluidly downstream of the fluid storage tank and exchanging heat between the cooling fluid and a heat load, a turbine fluidly downstream of the second heat exchanger and extracting mechanical energy from the cooling fluid, and a combustor fluidly upstream of the turbine and fluidly downstream of the second heat exchanger. The cooling fluid that has been heated by the second heat exchanger passes through the first heat exchanger and thereby heats upstream cooling fluid resident in the fluid storage tank, and the combustor is configured to ignite the cooling fluid flowing from the second heat exchanger such that combusted cooling fluid flows through and drives the turbine.
