I'm not sure some of you have read this correctly
“This static test airframe has the first set of wings built, and we have refined the structural design for subsequent aircraft due to increased weights etc. We will use this calibration of the FEM to prove the adequacy of the structure on production aircraft.”
Bascially what they are saying is that the current one failed close to the point predicted in the FE analysis. The wing has been redesigned anyway, and now they have calibrated the FE model and it is accurate they are happy to take the FE analysis of the new wing as read.
Whats the problem? Standard practice, calibrate an FE model at a few test points and then use the model. If you don't like that process then don't get in an aircraft, or a boat, or a car, or .....
