U.S. military investigation said the system operational errors Osprey aircraft crashed in Morocco
BEIJING, August 23,
According to China’s National Defense Science and Technology Information Network reported, April 12, 2012, a part of the United States Marine Corps MV-22B squadron VMM-261 type “Osprey tiltrotor aircraft called “African lion” military exercise with the Moroccan military crash. The accident led to the death of two Marines, two pilots were seriously injured. The survey results show that the cause of the accident is not a mechanical failure or security risks, but operational errors caused by the driver’s.
United States Marine Corps aviation deputy chief commander Robert Schmidle said the tiltrotor aircraft suffered a blow from the nose to the tail direction vertical takeoff airflow. When the height reached a height of about 24 feet, the aircraft’s climb to avoid the Marines on the ground pilots decided to perform a right turn putter operation.
when pilots turn operation, the original wind blowing from the direction of the head to the tail into a blow from the tail to the head direction. Time the pilots a total distance of the control rod rotation controller forward rotation of the aircraft engine nacelle, caused by the operation of the center of gravity of the “Osprey” forward offset.
tilting rotorcraft unique configuration, the driver of the pitch control rod not enough redundancy the fuselage looked up operation. So the aircraft on ground straight flight. Schmidle said the survey results show that the might of the accident would not have happened if the pilots continue to the Osprey “keep the helicopter mode.
Schmidle said the accident occurred when the aircraft in naval aviation operations training procedures standard manual safety warning, but the flight envelope in the manual and no explicit prohibition of the situation. Added to the manual should be more clearly complement Amendment. The MV-22 pilots will also be enhanced training to enhance the type tilting rotorcraft understanding which encountered a similar situation can make the correct operation. Schmidle also stressed the MV-22 tiltrotor aircraft is a safe and reliable aircraft. (China Aviation Industry Development Research Center, Huang Yu)
