    Abstract: In one aspect, a flexible fan blade for use in a centrifugal fan impeller having at least one of a rear plate and a front plate with an air inlet is provided. The flexible fan blade comprises a fixed central portion fixedly coupled to at least one of the front plate and the rear plate of the centrifugal fan impeller. The flexible fan blade also includes a trailing edge extending from the fixed central portion and being moveable between a first position and a second position. The trailing edge is fabricated from a compliant material. Furthermore, the trailing edge is flexible in relation to the fixed central portion between a first position and a second position. The flexible fan blade also includes a leading edge extending from the fixed central portion in opposed relation to the trailing edge.

    Abstract: A centrifugal blower system includes a centrifugal blower assembly for generating airflow. The centrifugal blower assembly includes a housing, a motor coupled to the housing, and at least one impeller coupled to the motor. A motor controller is coupled to the motor. The motor controller is configured to receive at least one feedback parameter and to transmit instructions to the motor to control an operation of the motor based on the at least one feedback parameter. The operation of the motor is configured to reduce noise in the centrifugal blower system.

    Abstract: A centrifugal blower assembly includes a housing (18) having an inner surface (25) and an outer surface(28). The inner surface (25) of the housing (18) defines in part an interior space. The centrifugal blower also includes a first portion of texture applied to at least a first portion of at least one of the inner surface (25) and the outer surface (28) of the housing. The first portion of texture has a first height based at least in part on a local boundary layer height of an airflow moving across at least one of the inner surface (25) and the outer surface (28) respectively. The first portion of texture is configured to generate a turbulent flow within the airflow moving across the first portion of texture.
