Description
Technical field
The present invention relates to fluid dynamic technical field, the performance improvement method of more particularly to a kind of fluid power plant and
Fluid power plant.
Background technology
Fluid power plant, such as aircraft wing, generating set blade, the propeller blade on various naval vessels, in air or water
Power can be produced Deng when rotating in fluid using pressure difference.
When current fluid power plant is rotated and run in a fluid to reduce and fluid friction, generally all can be by
Surface is set to streamlined, enables fluid to come quickly through apparatus surface with small friction of trying one's best.Even if however, by surface
It is set to streamlined, can not completely avoids the friction with fluid, thus by high temperature, resonance, vortex, noise caused by friction etc.
Problem is following.For example：For the problem of radiating, also have in apparatus surface perforate to strengthen the technology of radiating effect at present,
But even breaking plant overall rigidity and intensity can be so influenceed, is allowed to the presence of certain potential safety hazard.
