<p>Rotary engines utilize the Brayton cycle. The cycle of the engines includes the four strokes of intake, compression, expansion and exhaust. An open-cycle version (Figure 2) uses air as the primary working fluid while closed-cycle versions (Figures 7 and 10) use helium as the working fluid. Each engine includes an outer body (12) providing a cavity (14) and an inner body (16) within the outer body cavity (14) supported for relative movement with respect to the outer body (12). Four ports (61, 62, 72 and 74) provide access to the space between the inner and outer bodies. They are an intake port (61), compression port (62), expansion port (72), and exhaust port (74). A heat absorbing chamber (64) including a source of heat energy is open to the compression port (62) and the expansion port (72).</p> |
