Abstract:

A flight loading profile based solely on accelerometer data is developed which accounts for all fatigue damaging loads experienced by high performance aircraft. A random sequence of the flight loads is generated in a computer program that applies the ESDU comulative damage hypothesis for damage prediction of fleet aircraft. Data from actual accelerometer readings are used in evaluating whether reasonable results can be obtained from the program. The feasibility of implementing the program is discussed along with recommendations improving the suitability of the program for more accurate predictions. Author
