SYSTEM AND METHOD FOR GROUND VIBRATION TESTING AND WEIGHT-AND-BALANCE MEASUREMENT

摘要

PROBLEM TO BE SOLVED: To provide a system and method for determining weight and balance of an aircraft.SOLUTION: An apparatus for lifting an aircraft 10 may include a plurality of lifting mechanisms 74 mounted on a supporting surface 64. Each lifting mechanism 74 is configured to impart an upward force on a component 38 of the aircraft 10 for lifting the aircraft 10 off the supporting surface 64. The apparatus 70 includes a beam structure 100 configured to be mounted on the lifting mechanisms 74. The apparatus 70 also includes a lifting beam suspended from the beam structure 100. A measurement device 178 is mounted on the lifting beam and engages a jack point 54 associated with the component 38 to determine the weight of the aircraft 10 when the aircraft is lifted off the supporting surface 64.
