JET Mode of Wind / Hydro Turbine Operation
All my inventions related to the hydro and wind JET turbine applications are based on JET force creating an additional rotating JET torque. It is a radical new solution. Thanks to it the turbine efficiency is increased up to 2 times for both lift and drag devices on the vertical, inclined and horizontal axis hydro / wind rotors of axial and cross flow rotors. All JET augmented turbines are self starting devices at very low flow stream.
More see at www.tonchev.org/all.html
Generally, the jet blade turbines have very good performance at low flow velocity. See a scheme of a hydro power plant with over water drive power train coupled to the vertical shafts of the under water counter rotating turbines.
The jet blade turbines operate efficiently in both medium water and and air. A prototype in operation of a wind jet blade turbine
see at the video here. The jet blade water turbine prototype is testing. See animation of a hydrokinetic plant with new invented jet blade turbineMore information related to the jet augmented hydrokinetic turbines see here
Invented jet blades are applicable to wind turbines, as well. A short presentation of Darrieus wind turbines with new invented jet blades see here.
A JET S-ROTOR cross flow wind turbine ( test model) in operation is shown at this video here. S-ROTOR turbine is a drag / jet / lift machine. S-ROTOR turbine is constructed with two jet blade channels in the periphery of each blade. Power augmentation is up to 2 times for non-ducted applications. Low noise / high torque machine with direct drive low speed (rpm) permanent magnets alternator. Self start at low wind velocity. Very good performance at high turbulent winds and as a group of close spaced vertical axis jet wind turbine with a common drive train. Self braking effect at high wind speed.
See a picture of a vertical axis 3 jet blade under water hydrokinetic turbine here
An other type of submersible or semi-submersible turbine is axial flow hydrokinetic turbines - see a video of an free water stream turbine here.
