Propeller theory - Pilotfriend

Propeller theory. The forces. Propeller blades are constructed using aerofoil sections to produce an aerodynamic force, in a similar manner to a wing. Consequently the blades are subject to the same aerodynamics – induced drag, parasite drag, wingtip vortices, lift/drag ratios at varying aoa, pressure distribution changing with aoa etc.

Design of a windmill for pumping water - University of Nairobi

Wind energy can be generated using windmills that provide mechanical energy that is used directly on machinery e.g. water pump and grinder; or wind turbines that provide electrical energy. The main objective of our project was to design a windmill and therefore our scope will be limited to a windmill for water pumping water.

How do Windmills Generate Electricity?

The modern windmill is more correctly called as a wind turbine as it can generate electrical power. (The older windmills in contrast generated mechanical power.) Wind turbines are primarily divided into horizontal axis windmills and vertical axis windmills. The horizontal axis wind turbines are of the following types: Single bladed; Double bladed
