| titleOfInvention |
High-efficiency propeller with increased contact area |
| abstract |
Said invention is related to a propeller used in aircraft/sea vessels, pumping systems, wind and hydraulic turbines and to propeller blades (13) which are distributed around propeller (10) hub (11) and positioned so as to set an angle with the axis (x) of propeller hub (11), to a concave curvilinear contact surface (13.3) formed on the suction side (a) of said blades (13) that push water and to a convex outlet surface (13.4) which follows this concave surface (13.3) and is shorter than said concave surface (13.3).n[WO2012057717A1] |
