This tendency to decrease the blade angle is produced because all the parts of a rotating propeller try to move in the same plane of rotation as the blade's center line. At operational rpm, this force is greater than the aerodynamic twisting moment. It is used in some designs to decrease the blade angle. For training only (c) by Link & Learn Aviation Training GmbH 311 32 EASA Part-66 Training Handbook Module 17 LINK & LEARN Vibrational Force and Critical Range When a propeller produces thrust, aerodynamic and mechanical forces are present which cause the blade to vibrate. If this is not allowed for in the design, this vibration may cause excessive flexing and work-hardening of the metal and may even result in sections of the propeller blade breaking off in flight. Aerodynamic forces cause vibrations at the tip of a blade where the effects of transonic speeds cause buffeting and vibration. Mechanical vibrations are caused by the power pulses in a piston engine. They are considered to be more destructive in their effect than aerodynamic vibration.

A propeller is a rotating airfoil that consists of 2 or more blades. These blades are attached to a central hub which is mounted on an engine crankshaft. The function of the propeller is to convert engine power into useful thrust. The blades have a leading edge, a trailing edge, a tip, a shank, a face and a back as shown in Figure 2, details a) and b). Blade Angle Refer to Figure 3. 'Blade angle' (or: pitch angle) is the angle between the propeller's plane of rotation and the chord line of the propeller's airfoil section (i. e. of the blades).
