Nonlinear modeling improves rotorcraft safety

As part of the mission of the Structural Technology and Prototyping group, Boeing Rotorcraft engineers are pursuing greater uniform margins of safety for aircraft load capacity. A benchmark was set in 2003 when they simulated fatigue-causing loads on a CH-46E helicopter and defined an improved, efficient methodology for nonlinear FEA.
