In one embodiment, an apparatus comprises a shaft (328), a rotor (312), and a cam surface (404). The shaft comprises a spiral spline along a length of the shaft. The rotor comprises a blade (320, 322) extending from the rotor and a tubular hole (308) extending into the rotor. The tubular hole comprises a spiral groove (309) configured to mate with the spiral spline on the shaft. Relative rotation between the spiral spline and the spiral groove causes the rotor to linearly move along the shaft. The cam surface comprises a recession (402, 412). The blade nesting in the recession to constrains rotation of the rotor about the shaft and allows linear movement of the rotor along the shaft.
