Abstract
A turbine/compressor comprises at least one magneto-electric device and a drive train coupled to the magneto-electric device. At least one rotor blade is coupled to the drive train. The rotor blade has a shaped leading edge with a series of spaced tubercles formed therealong.
Claims30
A rotating machine comprising:
- at least one magneto-electric device;
- a drive train coupled to said magneto-electric device;
- and
- a plurality of rotor blades coupled to said drive train, each rotor blade having a continuous shaped leading edge extending generally the length of said rotor blade, said leading edge comprising a series of spaced tubercles formed therealong, said tubercles being configured to enhance lift, provide improved stall characteristics, reduce drag and reduce span-wise pumping.

A turbine comprising:
- at least one generator;
- a drive train coupled to said generator;
- and
- a plurality of rotor blades coupled to said drive train, each rotor blade having a continuous shaped leading edge extending generally the length thereof with a series of spaced tubercles formed therealong, said tubercles being configured to enhance lift, provide improved stall characteristics, and reduce at least one of drag and span-wise pumping.
1 more element
A rotating machine comprising:
- at least one magneto-electric device;
- a drive train coupled to said magneto-electric device;
- a plurality of rotor blades coupled to said drive train, each rotor blade having a shaped leading edge configured to enhance lift and reduce drag, said leading edge comprising a series of spaced tubercles formed therealong;
- and
- at least one control system configured to alter at least one of the spacing and shape of said tubercles.
2 more elements
A rotating machine comprising:
- at least one magneto-electric device;
- a drive train coupled to said magneto-electric device;
- and
- a plurality of rotor blades coupled to said drive train, each of said rotor blades comprising a tip and a root, each rotor blade undergoing a twist between said tip and root, each rotor blade having a series of spaced tubercles formed along a continuous leading edge thereof, said tubercles being configured to enhance lift, improve stall characteristics of said rotor blade and reduce at least one of drag and span-wise pumping, the degree of twist being selected to take said enhanced lift and improved stall characteristics into account.
