  • Scroll compressor with adjustable capacity
    Patent number: 6736621
    Abstract: A scroll compressor includes an adjustable actuator mount that changes the relative position of a non-orbiting scroll and an orbiting scroll to change the compressor capacity. In one embodiment, the scroll wrap and base of each scroll are manufactured as two separate components with a wrap modulator between the scroll wrap and the base of each scroll. As the mount moves the scrolls apart and together, the wrap modulators extend and retract the scroll wraps relative to their respective bases to maintain fluid-tight compression chambers.

  • Deployable vortex turbine for dissipating or extracting energy from a lift induced vortex emanating from an aircraft
    Patent number: 5702071
    Abstract: An aircraft (10) including a stowable, wingtip mounted, vortex turbine (30) for dissipating or extracting energy from a lift induced vortex (28) emanating from the aircraft (10) is provided. The vortex turbine (30) includes a first and a second array (38, (40) of blades (32a,b) (34a,b) extending respectively from a first and a second hub section (32), (34). Hub sections (32), (34) may be independently pivoted about a common axis of rotation (36) to a stowed position for landing, take-off, or ground operation, whereat none of the blades (32a,b) (34a,b) extend below a minimum ground clearance of the aircraft, or beyond a maximum horizontal extension of the wing (16). In flight, the hub sections (32), (34) may be deployed and the pitch of the blades adjusted to maximize dissipation of the lift induced vortex (28), thereby minimizing drag and providing improved safety for other aircraft flying through the wake of the aircraft (10) producing the vortex (28).
