Fan performance can be adjusted based on real-time operating conditions. The fan can include a plurality of blades operatively connected to a rotor. The blades can extend radially outward from the rotor to a tip. A housing can substantially surround the fan. The housing can have an inner peripheral surface that defines an inner diameter. The inner peripheral surface can include a first portion and a second portion downstream of the first portion. The first portion can be adjacently upstream of the plurality of blades, and the second portion can be substantially aligned with the plurality of blades. A plurality of actuators being distributed in a circumferential direction of the housing. The actuators can be operatively positioned to cause the inner diameter of the first portion or the second portion to be altered. As a result, one or more performance characteristics of the fan can be changed.
A system for fan performance tuning, the system comprising:
A method of fan performance tuning, a fan includes a plurality of blades operatively connected to a rotor, the plurality of blades extend radially outward from the rotor to a tip, a housing substantially surrounds the plurality of blades, the housing defines an inner peripheral surface and has an inner diameter, the inner peripheral surface includes a first portion and a second portion, the first portion is adjacently upstream of the plurality of blades, the second portion is substantially aligned with the plurality of blades, and the inner diameter being alterable at the first portion and at the second portion, the method comprising:
