    Abstract: A wheel for a rotating flow machine, comprising a rotor (1) on which a plurality of blades (2) are arranged projecting radially from the rotor (1), with each blade (2) having a root (3) attached to the rotor (1) and a blade top (4). In addition, the wheel comprises a ring (5) arranged concentrically in relation to the rotor (1) outside the blade tops (4) in such a way that the ring (5) and the blades (2) overlap each other when the ring and the blades are viewed in a radial direction, which ring (5) is arranged to be caused to rotate by the blades (2) when the rotor (1) rotates. The extent (9) of the blades (2) in a radial direction and the internal dimension (10) of the ring (5) are matched to each other in such a way that there is a clearance (Δ) between each blade top (4) and the ring (5) in radial direction when the rotor (1) is not rotating.

    Abstract: A turbomachine for moving air (10) includes a shroud (12) disposed about a longitudinal axis and a rotor assembly (14) mounted for rotation about the longitudinal axis. The rotor assembly (14) has a plurality of blades (18) and tips of the blades (20) are coupled to an annular band (24). The annular band (24) is disposed with respect to the shroud (12) so as to define a gap extending continuously between an outer surface of the annular band (24) and an inner surface of the shroud (12). A seal structure (30) extends from the inner surface (32) of the shroud (12) and into the gap (16) to reduce swirl and minimize air leakage across the gap.

    Abstract: An improvement to forwardly skewed axial fans (20) where blade chamber and rake are coordinated with skew. The blades (5) are characterized in that a line defined by the points of maximum chordwise camber (fmax) as a function of changing radial position (r) is on the leading edge (LE) side of the mid-chord line (MCL) at values of r, toward the root of the blade (5), and is less forwardly skewed than the leading edge (LE), the mid-chord line (MCL), and the trailing edge (TE). The blade (5) is raked forwardly so that the trailing edge (TE) of the blade tip is axially forward of the trailing edge (TE) at the blade root. As a result, the fan (20) produces a flow that is generally in radial equilibrium, having a reduced component of flow normal to the desired axial flow and normal to the tangential flow. The coordinated fan (20) can be combined with a housing/band (62,66) configuration for controlling airflow that recirculates in a channel (68), formed between the band (66) and the housing (62).

    Abstract: A blade (14) for a fan or blower (10) which has an abrupt transition region between an inner blade region which has a negative leading edge sweep angle, and an outer blade region which is highly forwardly swept. The outer blade region is further characterized by a blade chord that increases with increasing radius. The fan provides a low pitch width and superior noise and efficiency trade-offs.
