Book Description
Results are given for a brief investigation of the relative rates of fatigue-crack propagation obtained in helicopter-rotor-blade fatigue tests in which simplified, equivalent-total-lifetime, fatigue-test loadings at zero mean load are used to simulate a flight fatigue loading that includes a mean tension load. The conventional equivalent-lifetime loadings do not give equivalent rates of crack propagation. For typical rotor-blade loadings, which included large mean tension load, the general trend was toward greatly reduced rates of fatigue-crack propagation under the equivalent-lifetime loadings provided a nonconservative basis for establishing rotor-blade inspection intervals.

Book Description
The rate of crack propagation from an induced defect in a metal Bell Helicopter 540 main rotor blade was investigated. A controlled crack front was introduced into the top surface of the blade spar. Fatigue testing was conducted at maximum level flight loads and the crack growth was monitored. Experimental data was then comapred with analytical predictions to measure the ability to predict crack growth characteristics. (Author).
