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 Cumulative 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.
