One
of method for reduction of vibrations at source is integration of
vibration dampers to the crankshaft. The dampers are moveable
weights attached to the crankshaft by pins and bushings. The
dampening effects are designed to reduce peak vibratory stress
occurring at specific frequencies in certain parts of the engine or
the propeller or both [8]. Next method is reduce the vibrations at
connect points between engine and fuselage usually with use passive
elements (engine mounts). Another alternative is to look at
effective reduction of the vibrations affecting and acting upon
the pilot’s body is to minimize or isolate vibrations on aircraft
