WebThe Brayton cycle (or Joule cycle) represents the operation of a gas turbine engine. The cycle consists of four processes, as shown in Figure 3.13 alongside a sketch of an engine: a - b Adiabatic, quasi-static (or … WebBrayton machines can achieve 40% of Carnot at cycle tem-perature ratios between 3 and 4, while free-piston Stirling machines can achieve 60% of Carnot at temperature ratios between 2 and 3. The equivalent fraction of Carnot for space thermoelectric power converters at temperature ratios between 1.5 and 2 is less than 20%.
