Abstract
A turbine blade system relating to a tip device appended to the blade tip of a turbine. The tip device controls the flow of air to ultimately reduce noise signatures while increasing aerodynamic efficiency. Passive or actively controlled configurations also permit the user to adjust the pitch angle of the tip device for maximum efficiency rather than making less effective adjustments to the entire turbine blade.
Claims20
A turbine system, comprising:
- attaching a tip device to a blade tip of a turbine blade;
- forming the tip device to be appended from the blade tip;
- extending the blade tip through an inner tube wall of the tip device;
- forming the tip device to have a textured interior;
- enhancing power production through a plurality of cylinders formed with the tip device;
- reducing noise signature through a plurality of cylinders formed with the tip device;
- producing an aerodynamic flow jet via the tip device;
- and
- reducing effects of a trailing eddy created from turbine blade rotation by using an opening of the tip device and the textured interior to interact between air flow and the tip device.
