A telescopic wind tower with reduced environmental impact - The Perima Project

Abstract

A prototype of a telescopic pole for wind energy production with low environmental impact and its lifting system for a 60 to 250 kW turbine and a height of 30 m have been designed and manufactured. A telescopic tower, which is raised and lowered by automation or by remote control, allows to differentiate the presence of the generator within the landscape over time. Research target: the optimal design of the telescopic coupling, the design for maintaining the preload and for the rotational decoupling, the optimization of the pairs of sleeves, the design of the pegs and the bushes of the jack-up lifting system. All the components of the wind tower have been preliminary analyzed through FEM stress computational analysis. The prototype was installed in Caltanissetta, Italy, and successfully tested.
