Abstract: The Flap Turbine (FT) is a novel sort of Vertical Hub Turbine (VAWT) where the cutting edges are made of versatile folds. These versatile folds, when joined together, go about as a sail or cutting edge for the VAWT. This kind of turbine is otherwise called a check valve turbine as a result of the check valve like the conduct of the moving folds. At the point when the sail is moving the downwind way, the folds are shut and won’t permit air (water if the turbine works in the water) to go through the sail. In any case, when the sail is moving the upwind way the folds will be in the vacant position and permit air (or water) go through the sail. Basically expressed, a wind turbine works the inverse of a fan. Rather than utilizing power to make wind, similar to a fan, wind turbines utilize twist to make power. The wind turns the sharp edges, which turn a pole, which associates with a generator and makes power.
