WebThe dynamic rollover phenomenon is also known from helicopters [12]. If the skid or wheels contact a xed object on the ground while hovering sideward, a rolling moment due to the rotor force may occur. Most eective way to stop the helicopter rollover is to apply down collective to remove the rotor lifting force. WebApr 11, 2024 · In a rotary aircraft, strictly speaking, the take-off occurs when the pilot lifts the machine off the ground into hover. This is the only part that is conventionally called a take-off. The process of accelerating from hover to forward flight has a different name that is specific to helicopters. It is actually called a ‘transition’.
