Title:
ULTRA-WIDE CHORD TRIGONOMETRIC WAVEFORM BLADE
Document Type and Number:
WIPO Patent Application WO/2019/196919
Kind Code:
A1
Abstract:
An ultra-wide chord trigonometric waveform blade. The pressure surface of the blade profile of the blade is designed as a trigonometric tangent or cotangent waveform curve structure. The tangent or cotangent waveform curve is used as the surface of the blade profile, so that not only the blade structure under a subsonic working condition can be designed, but also the blade structure under a supersonic working condition can be designed. Especially under the supersonic working condition, strong shock waves in a flow path of a gas compressor and large flow losses caused thereby can be effectively avoided.
