System and method for ground vibration testing and weight and balance measurement

摘要

An apparatus for lifting an aircraft may include a plurality of lifting mechanisms mounted on a supporting surface. Each lifting mechanism may be configured to impart an upward force on a component of the aircraft for lifting the aircraft off the supporting surface. The apparatus may include a beam structure configured to be mounted to the lifting mechanisms. The apparatus may also include a lifting beam suspended from the beam structure. A measurement device may be mounted to the lifting beam and may be configured to engage a jack point associated with the component to determine a weight of the aircraft when the aircraft is lifted off the supporting surface.

1. An apparatus for supporting an aircraft during ground vibration testing, comprising:
a plurality of lifting mechanisms mounted on a supporting surface, each lifting mechanism being configured to impart an upward force on a component of the aircraft for lifting the aircraft off of the supporting surface; a beam structure configured to be mounted to the plurality of lifting mechanisms; a lifting beam suspended from the beam structure; a jack fitting sized and configured to fit within a bore formed in a component of the aircraft at a jack point, the jack fitting having a lower surface and a shaft extending below the lower surface; a load cell having an upper surface and an opening, the jack fitting shaft extending through the load cell opening and into a bore associated with the lifting beam, the load cell upper surface being in bearing contact with the jack fitting lower surface; and the load cell determining a weight of the aircraft when the aircraft is lifted off the supporting surface.
