A Feasibility Study for Monitoring Systems of Fatigue Damage to Helicopter Components
Abstract
The report describes efforts to monitor and record the in-flight operations of UH-1H and CH-47C helicopters for the subsequent assessment of the fatigue damage to their structures, four types of monitoring were investigated: (1) flight condition monitoring, (2) component-load monitoring, (3) mission-type monitoring, and (4) direct monitoring. After the recording systems and corresponding data processing systems were identified for each monitoring type, each type was tested for its technical acceptability and cost-effectiveness. Study results indicated that the flight condition monitoring is best for the UH- 1H and also for the CH-47C provided that the monitoring of gross weight for the latter model becomes technically acceptable.
