Darrieus wind turbine. The Darrieus wind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from wind energy. The turbine consists of a number of curved aerofoil blades mounted on a rotating shaft or framework. The curvature of the blades allows the blade to be stressed only in tension at high rotating speeds.
Helical wind turbines are a type of vertical-axis wind turbine (VAWT) with conjoined scoops or twists that are arranged in the shape of a helix. Engineers have developed this design in an effort to
Recently, a micro-hydropower generation system has been introduced for generating electricity by installing a spherical helical turbine in a water pipe line having a circular cross section. In this study, flow analyses through two ducted spherical helical turbines were
The vertical-axis helical-bladed hydrokinetic turbine serves as a viable source of renewable power that can extract kinetic energy of the free flowing water to generate electricity. Such helical-bladed turbines are characterized by lesser pulsation of torque and marginally favorable starting capability as compared to straight-bladed turbines.
Denoting the solidity of the helical turbine by S (projection of blades on the shaft''s plane) [25], we can calculate it using the expression: (2) S = 2 n H r π (d + ∑ k = 1 n sin (k π n-d)-sin k π n) where n is the number of blades, H and r are height and radius of the

This patent, invented by Robert Luke Morales and Andrew John Kruse, was granted on February 27, 2001. This patent describes a hydro-alternator, which generates electrical power, to recharge the batteries on a bass fishing boat. The design consists of a body that is rigidly mounted to the outboard motor of a boat.
Vertical axis lift-based pipe turbine Evolving from the Darrieus wind turbine, the Gorlov helical turbine (Gorlov, Citation 1995) was developed by changing the blades from straight to helical in an attempt to decrease the encountered pulsatory torque issues and increase turbine efficiency.
Above all vertical axis wind turbines, for their lower cost and independent on wind direction, Savonius rotor takes the advantage to be more suitable for some implementation. Thus, many investigations have been carried out to improve its efficiency. This study emphasizes on the effect of the overlap distance and the blade shape on a

A 100-W helical-blade vertical-axis wind turbine was designed, manufactured, and tested in a wind tunnel. A relatively low tip-speed ratio of 1.1 was targeted for usage in an urban environment at a rated wind
The helical turbine developed by Gorlov in 1994–1995 has rotor blades with a helical shape that lessen turbine pulsation while also increasing speed and efficiency (Gorlov, 1998). Gorlov A. developed a helical turbine model for a small community or even a single home on a river or tidal coastline with a few kilowatts of power ( Gorlov, 1998 ).
In this paper, we attempted to measure the effect of Bach''s section, which presents a high-power coefficient in the standard Savonius model, on the performance of the helical Savonius wind turbine, by

The Gorlov helical turbine ( GHT) is a water turbine evolved from the Darrieus turbine design by altering it to have helical blades/foils. Water turbines take kinetic energy and translate it into electricity. It was patented in a series of patents from September 19, 1995 [1] to July 3, 2001 [2] and won 2001 ASME Thomas A. Edison.
This report presents the rotor blade design, turbine construction and the results of the experimentation of a helical vertical axis wind turbine (VAWT). These
Helical wind turbines are a type of renewable energy technology that has the potential to revolutionize the way we generate electricity. Unlike traditional horizontal-axis wind turbines, which have
Sep 27, 2011. The helical wind turbine is a peculiarly-shaped piece of green technology that harvests energy from wind. In most cases, the design of the helical wind turbine features some kind of spiral. These turbines often look like giant DNA helixes or oversized drill bits pointing to the sky.

Darrieus Rotors. The Darrieus rotor is a type of vertical axis wind turbine (VAWT) known for its distinctive eggbeater shape. It consists of curved airfoil blades that are arranged in a vertical orientation around the central axis. Darrieus rotors are named after Georges Jean Marie Darrieus, a French engineer who patented the design in 1926.
The vertical blades of the Darrieus turbine were improved with helical one, as the probability of finding a section increases with a particular angle of attack. GHT was developed by Professor Alexander M. Gorlov of North-eastern University in 1995 [14].

Helical wind turbines are a type of vertical-axis wind turbine (VAWT) with conjoined scoops or twists that are arranged in the shape of a helix. Engineers have developed this design in an effort to capture the greatest amount of kinetic energy from the wind and generate clean electricity. They are more efficient than the average VAWT,
Among the lift type vertical-axis wind turbines, helical-blade wind turbines have a narrower range of output fluctuation compared to Darrieus and gyro-mill wind turbines, and their efficiency is higher due to the larger wind
