Design, prototyping and experimental testing of a chiral blade system for hydroelectric microgeneration

With the aim of investigating the applicative possibilities of chiral blade turbines in obtaining energy from water conduits with low velocity of flow, the present study traces a design procedure, defining analytical tools and identifying various expedients which can guide the effective choice of the functional parameters of the device and allow a preliminary estimation of the quantities in play, confirming their suitability by the construction of a prototype and its functional characterisation as a real device.
