Abstract
The Wells turbine is investigated, as well as its difficulty in running up to operational speed when started from rest (known as ''crawling''). A schematic is presented of: the Wells turbine; a typical graph of the tangential force coefficient (C /SUB r/ )-angle of incidence curve for a symmetrical airfoil; and graphs showing the influence of hub-to-tip ratio and solidity on starting and efficiency. In order to avoid crawling, a high solidity and a low hub-to-tip ratio rotor is required.
