The aim of the project is to investigate the residual strength of composite blades of aircraft propellers with automatic speed control, intended for piston engines. The use of composite materials allows achieving the strength and stiffness of propeller blades at the level of high-strength aluminum alloys, but at a weight comparable to a wooden structure. For use on engines with a high level of vibration, it is necessary to address the issue of long-term service life and residual strength of the joint connecting the fiber composite with metals in the bearing in the propeller head. Cyclic components of forces originating from the control are also considered and climatic influences will be included.
