Multi-beam method and apparatus for removing and replacing major structural components while converting an airplane to efficiently carry freight

摘要

A method of jacking an aircraft when removing and replacing major structural components thereof, comprising: providing a plurality of jacks; analytically dividing the aircraft into panels; determining a weight and a center of gravity of each panel; providing a weight distribution for the length of the aircraft; providing a computer program, which uses a moment distribution method, and utilizing it to balance the multiple-jack inputs and the aircraft weight distribution until the fuselage bending moments are within a predetermined acceptance level; and simultaneously loading the jacks. 1526 כ' בתמוז התשס" ב - June 30, 2002
