An air-flow, propeller type, rim-drive turbine is being manufactured to be used in sites with heads ranging from 12 to 28 feet. A laboratory turbine model study was conducted to optimize several turbine variables. The model study provided revealing information in regard to the effect of bearing arrangement and blade angle on turbine performance. The model study also provided a means of testing various mechanical peripheral equipment associated with the turbine such as water seals, and bearing location. In particular, the performance of the turbine with a downstream bearing support web was tested.
