B64C2230/00 - CPC Classification

Classification description:

Boundary layer controls

Sub-classes:

B64C2230/02 » by using acoustic waves generated by transducers 28
B64C2230/04 » by actively generating fluid flow 199
B64C2230/06 » by explicitly adjusting fluid flow, e.g. by using valves, variable aperture or slot areas, variable pump action or variable fluid pressure 133
B64C2230/08 » by influencing fluid flow by means of surface cavities, i.e. net fluid flow is null 39
B64C2230/10 » by influencing fluid flow by heating using other means than combustion 9
B64C2230/12 » by using electromagnetic tiles, fluid ionizers, static charges or plasma 92
B64C2230/14 » achieving noise reductions 71
B64C2230/16 » by blowing other fluids over the surface than air, e.g. He, H, O or exhaust gases 28
B64C2230/18 » by using small jets that make the fluid flow oscillate 75
B64C2230/20 » by passively inducing fluid flow, e.g. by means of a pressure difference between both ends of a slot or duct 58
B64C2230/22 » by using a surface having multiple apertures of relatively small openings other than slots 72
B64C2230/24 » by using passive resonance cavities, e.g. without transducers 12
B64C2230/26 » by using rib lets or hydrophobic surfaces 118
B64C2230/28 » at propeller or rotor blades 40
