Setting Blade Pitch for Sensenich Composite Propeller
Sensenich two-blade ground-adjustable propeller The Sensenich t wo- b lade c omposite p ropeller for Rotax and Jabiru en g ines is light-weight, strong, and very efficient. For our Zenith 601HDS plan e with a Rotax 912 engine, the ground-adjustable propeller de livers strong take-of f performance as well as good cruise speed . S moothness through out the entire rpm range rivals that of more complicated and less efficient three-blade pro pellers. The secret to outstanding pe rformance is a very pr ecise setting of the propeller pitch so that the angles of attack of the two blades differ by less than 0.1 degrees. Such precision can be achieved with a high-quality propeller protractor where accuracy is guaranteed to be +/-0. 05 degrees for each blade, since then total error between blades is +/-0. 1 d egrees. The same accuracy can be ach ieved with basic workshop tools and parts....
