Abstract—This paper explores the design space that exists between multi blade, high-solidity water-pumping turbines with trapezoidal blade design and modern rectangular horizontal axis wind turbines (HAWTs). In particular, it compares the features and performance of a small 18-bladed, highsolidity HAWT with trapezoidal blade to that of a rectangular bladed 18-bladed HAWT. This is achieved through a detailed analysis of the effects of several minor changes to the nominal design of the exist blade. The redesigned blade is rectangular in shape which is to be capable of delivering rated power at the rated speed required by the 18-bladed HAWT, while operating at good efficiency
