Abstract:

The report presents the results of a wind tunnel test performed in the Boeing-Vertol wind tunnel on a 13 scale VSTOL 4-bladed cyclic pitch propeller, having a total activity factor of 640. The propeller was tested as both an isolated propeller and as an installed propeller. The primary objectives of the test were to determine the effectiveness of cyclic pitch control for longitudinal control during hover and transition, the change in power required for cyclic pitch control and blade and hub loads for use in design and for verification of analytical methods.
