Selection of the working medium for 6- to 12-kW closed organic-fuel-powered gas-turbine plants

Selecting a thermodynamic cycle for the closed gas-turbine power plant of spacecraft in order to minimize surface of the cooler-radiator

“…One of the major problems that hinders the creation of spacecraft CGTPPs is the necessity of using a low temperature cooler radiator with large surface area. This requirement is related to the small ratio of the cycle maximum ( ) to minimum ( ) temperatures ( ≈ 3-3.5), which limits the maximum acces sible level of efficiency and work of a given cycle [2,4]. As long ago as in 1930, G.I.…”
