Abstract:
A compressor wheel (20) for an air boost device and a method for designing the wheel are provided. The compressor wheel (20) comprises a hub (24) and a plurality of blades (22, 23) connected to the hub (24). The plurality of blades (22, 23) have a ratio (f/N) of natural frequency to maximum rotational speed of less than 4.0 and are made from a titanium alloy. The plurality of blades (22, 23) can comprise a plurality of full blades (22) and a plurality of splitter blades (23).
