| 摘要 |
The present invention provides a high efficiency compressor wheel with highly backswept blades, such that the wheel provides optimal efficiency over a wide operating range. The compressor wheel is made of titanium, which provides for an acceptably thin blade thickness while providing a backsweep of more than 50° and improves the aerodynamic flow characteristics within the compressor wheel's flow channels. By providing stable operation at both lower and higher flows allows a compressor to provide stable flow over a wider range of engine operating conditions, thereby accommodating higher engine speeds, torques and boost levels. The internal flow characteristics provided for by the present invention also reduces efficiency losses associated with flow separation and recirculation, which results in improved compressor efficiency.
