Difficulties of designing propellers with pitch variable in flight; formulas for calculating forces acting at blade root developed; couple perpendicular to plane of bearing which is absorbed by action of balls; value of total torque found to be very high; Ratier Company developed helicoidal thrust bearing; two- and three-bladed wood propellers; details of Ratier propellers; mechanisms for controlling variations in pitch.
