The report presents the key results of a model wing tunnel test program that was directed towards investigating the use of cyclic pitch propellers as the low speed longitudinal control system of a four propeller V STOL tilt wing transport-type aircraft. The almost linear pitch control effectiveness of this system through transitional flight and in-ground effect along with the correlation with theory is discussed, and the moderate power increase associated with its use is shown.
