Impeller of gas compressor

Номер: CN116591988A
Автор: HUO PEIFENG, DONG JINSHAN, HE FANG, LI XIN
Принадлежит:

The invention discloses a compressor impeller which comprises a hub, a plurality of long blades and splitter blades are arranged on the hub, the long blades and the splitter blades are distributed on the hub at intervals, dense-tooth comb-shaped flow channels are distributed on the hub between the long blades and the splitter blades, each splitter blade comprises an air inlet edge, and each air inlet edge is provided with an air outlet. A plurality of arc-shaped flow channels are densely distributed on the edge of the air inlet side; the special splitter blades are in a curved swept front edge blade shape, so that the shock wave strength of the front edges of the blades can be effectively reduced, the internal flow of the impeller is improved, the generation of secondary flow is inhibited, the airflow uniformity of a low-speed area is improved through the dense-tooth comb-shaped flow channels and the arc-shaped flow channels which are specially arranged on the impeller, the surge margin ...

The invention provides an effective sortie assessment method for aircraft flight trial. The method includes: respectively adopting two calculation methods according to the fact whether the aircraft a trial flight belongs to a comprehensive test subject or a single test subject to acquire success rate of a flight trial sortie; judging whether the trial flight is the effective sortie or not according to the threshold of the success rate. In the method, interference of artificial subjective factors and more external environment factors can be eliminated as much as possible, and effectiveness of the aircraft flight trial sortie is assessed scientifically, quantitatively and objectively; a flight trial list is standardized, trial flight contents are scientifically and reasonably demanded and arranged, driving techniques of the trial flight are accurately mastered, the test methods and instruments are used correctly, reliability in maintenance and field work guarantee is improved, collaboration ...
