Electric Motor Whirl Test of a Flottorp Standard Two-Blade Propeller and a Flottorp Standard Two-Blade Propeller Incorporating Nemeth Modified Leading Edge (Whirl Test No. 2355)
Abstract
The electric motor whirl test of a Flottorp 'standard' two blade, six ft. diameter, wood, fixed-pitch propeller was conducted. An electric motor whirl test was then conducted on a similar 'standard' Flottorp propeller that had been modified along the leading edge by the Nemeth Aeronauticl Laboratory, Chicago, Illinois. The modification consisted of a series of smooth indentations, in wave form, from about the 0.3 radius out the tip of the blade. It was claimed by Nemeth Aeronautical Laboratory that such modifications would increase thrust produced at any given horsepower and rpm condition. Test data are presented covering static calibration of the two propellers for comparative purposes. Calibration consisted fo the measurement of the values of the thrust produced and horsepower absorbed at various rpm. Results of the tests were inconclusive.
