Torsion Vibration Damper (TVD)
Between gearbox and crankshaft a torsion vibration damper is implemented to reduce torsion
vibration. On one hand the crankshaft is protected from vibrations coming from the propeller, on the
other hand the gearbox is protect from vibrations coming from the crankshaft and the combustion
process. The damper is composed of two elements, a mass and an energy dissipating element. The
mass resists the acceleration of the vibration and the energy dissipating element absorbs the
vibrations.
Crankshaft
The crankshaft of the AE 300 is made of vacuum remolded, forged steel. The crankshaft has 5 main
bearings.
