<p>Embodiments of rotary vane engines (26, 300, 320) include rotors (44) that rotate about an axis of rotation (T). The rotors can be moved in directions substantially perpendicular to the axis of rotation (T) to vary expansion and/or compression ratios of the rotary vane engines (26, 300, 320). The ability to vary the expansion and/or compression ratios can facilitate optimization of the performance of the rotary vane engines (26, 300, 320) as operating conditions vary.</p> |
