Helicopter effective translational lift
WebThe following video demonstrates the ETL, or also called translational lift effect. The lift of the rotor will increase by passing a certain relative airspeed, usually about 20ktn. This will led to pitching up the nose while passing this airspeed. This effect is shown here by keeping the collective untouched. You can see how the helicopter ...
