A compressor comprising: an drive shaft; a first compressor wheel; a second compressor wheel connected to the first compressor wheel via the drive shaft; and two or more helical seals disposed on the drive shaft, each helical seal of the two or more helical seals extending away from an outer surface of the drive shaft and around a circumference of the drive shaft, wherein the two or more helical seals are configured to inhibit flow of fluid between the first compressor wheel and the second compressor wheel.

Helical seal for multi-stage compressor

A compressor comprising: a first compressor wheel comprising a first chamber configured to retain a medium, a first impeller disposed within the first chamber and configured to revolve around a longitudinal axis of the compressor, and a first diffuser coupled to the first chamber; and a second compressor wheel comprising a second chamber disposed radially outwards of the first chamber relative to the longitudinal axis, wherein the second chamber is configured to receive the outputted medium from the first chamber, a second impeller disposed within the second chamber and configured to revolve around the longitudinal axis of the compressor within the second chamber, and a second diffuser coupled to the second chamber, wherein each blade of the first impeller defines a fillet extending along an outer edge of the blade, and wherein a width of the fillet along a surface of the respective blade varies along the longitudinal axis.

Outflow valve (OFV) assemblies including non-metallic frames and enhanced attachment features are provided. In embodiments, the OFV assembly includes a non-metallic frame to which at least one valve door is pivotally mounted. The non-metallic frame may, in turn, include a generally rectangular frame body, a central opening through the frame body, an outer peripheral flange extending around at least a portion of the frame body. Frame attachment interfaces are distributed or spaced around the outer peripheral flange of the non-metallic frame. The frame attachment interfaces include fastener openings and elevated platform regions, which project from an inboard side of the outer peripheral flange and through which the fastener openings extend. Base plates seat against the elevated platform regions. Fasteners engage the base plates and extend through the fastener openings to an outboard side of the outer peripheral flange to attach the OFV assembly to an aircraft fuselage.
