摘要： A fan for cooling an electronic device is described, wherein the fan can include an enclosure and a motor secured within the enclosure. The fan can also include an impeller to be turned by the motor, the impeller having a plurality of blades, wherein an angular spacing of the blades results in an audio spread-spectrum within a range of audio frequencies. In some examples, an arrangement of the blades has a center of mass below a threshold, and the angular spacing of the blades and a blade pass frequency (BPF) results in sound that is distributed in the range of audio frequencies.

摘要： A method of balancing a gas turbine engine rotor, including axisymmetrically removing an annular portion of the balancing flange exceeding that required to provide the unbalance correction, and creating the unbalance correction by non-axisymmetrically removing material from the balancing flange. In one embodiment, the configuration of a theoretical notch in the balancing flange that would create the unbalance correction is determined. The unbalance correction is created by removing material from the balancing flange to create a protuberance protruding radially from a remainder of the balancing flange, the protuberance having a height corresponding to the depth of the theoretical notch, a circumferential width corresponding to the arc angle of the theoretical notch, and a circumferential position diametrically opposed to the circumferential position of the theoretical notch. A gas turbine engine rotor is also discussed.

摘要： Disclosed is a method in which the propulsive power of a drive nozzle (2) is controlled by means of a programmable logic control device (24) having an adjustable internal controller (25) in dependence upon the rotational frequency of a turbocharger rotor (1) detected by a speed sensor (26). Parameters necessary for control are determined empirically in a tuning run which includes tuning the controller (25) to a proportional control action with high gain Kp and inputting the nominal balancing speed as target value for the controller (25), monitoring and comparing the actual speed with the target value. If the actual speed exceeds the set target value, halving the gain Kp of the controller (25) and repeating the run until the actual speed is below the set target value. Then it includes approximating the actual speed to the target speed by generating an additional target value, additively applying the additional target value to the target value, and incrementing or decrementing the additional target value until the target speed of the turbocharger rotor (1) is reached.
