Abstract
An air-moving device may include an aerodynamic rotor in the form of a bladed disk. The aerodynamic rotor may include a physical geometry that constrains a noise level of the air-moving device.
Claims25
An apparatus configured to move air through an air-moving device,
- a rotor configured to be axially rotated within a duct, the rotor comprising:
- a central hub;
- a quantity of blades between 12-100 blades, wherein each blade has a proximate end that is contiguously formed with the hub of the rotor and radially extends away from the hub to terminate at a terminal end, and wherein each blade has a blade aspect ratio between 1 and 10;
- and
- a shroud contiguously formed with and circumscribing the terminal ends of the blades;
- wherein the rotor is configured to rotate with a blade passage frequency (BPF) in a range of 8-16 kilohertz (kHz) to create thrust.

- a housing that defines a primary airpath between an inlet end and an outlet end;
- wherein the rotor is configured to be axially rotated within the housing at a blade passage frequency (BPF) in a range of 8-16 kilohertz (kHz) and at a fan pressure ratio within a range of 1.01-1.2 to create thrust.
