All Vetus engine mouting absorb the propeller thrust.
The torque of an engine is one of the deciding factors for determinations of the load applied to the engine mounts. When more powerful engines are installed, it is important to use the following formula to define the load per support in kg (4 supporting points).
(engine weight in kg / number of supports) + (kW x 487 x reduction of gearbox / engine rpm x centre to centre spacing in meters of longitudinal engine bearers) = max. load per support in kg
Type K50V
For smaller engines up to approx 60 kW (80hp)
