When Marshall of Cambridge Aerospace wanted to install a cargo door in the forward fuselage of Tristar jets, the company opted to use load cells from Nobel Systems to ensure that the fuselage didn’t distort during cutting.
Cargo doors were fitted as part of a passenger-to-freighter role conversion programme.
The delicate operation required the fuselage to be in a neutral load configuration, equivalent to that of the original aircraft jig position. This would prevent any distortion arising from stresses induced when the primary structure was severed and removed.
Engineers achieved this by applying known loads to the structure to nullify the aircraft weight and to accomplish a configuration as close as possible to the jig position.
