In an effort to determine the feasibility of applying the U.S. Army-developed SIRS recording system to U.S. Navy helicopters, a study was conducted into the specific application of SIRS on the RH-53D helicopter. A fatigue damage assessment model was formulated for nine fatigue-critical dynamic components of the RH-53D helicopter, and two possible flight condition monitoring systems were synthesized. Both systems were found to be technically acceptable, but only one was practical based on current recording technology. The resulting system was analyzed from a life-cycle cost viewpoint and found to be cost-effective.
