Large Scale Propeller Testing in the NRC 9 Metre Wind Tunnel in Canada 830751
A large scale propeller test facility has been developed by De Havilland Aircraft of Canada for the National Research Council of Canada 9 metre wind tunnel. The facility is described fully along with the test programs recently undertaken.
Forward and reverse testing has been undertaken of propellers up to 8.5 ft. diameter. Some results are reviewed with respect to predicted propeller performance. The installation effects of external deicer boots, erosion protection and spinner/blade interfaces are also discussed.
