Abstract: Under the alternating loads, the strain gauges were arranged on the test pieces'
surfaces of airfoil web, the stresses and strains of test pieces were recorded, and the sizes and
positions to fatigue damage in the test pieces were detected by X-rays. The positions and damage
severities of test pieces were determined, and the crack growth lifes of airfoil structural parts
were predicted. Test result shows that the fatigue lifes of test pieces are approximate one million
cycles under 40 kN sinusoidal alternating compression load, and they are in good agreement with
the expected distribution of fatigue life (ten thousand-one million cycles). The stresses and
strains from fatigue test and theory calculation are similar in variation trends, and the errors are
about 10%. The high load and the moment around x axis cause the rivet failure and sheet
fracture of test pieces, and the predicted fatigue crack growth life is 10 183 cycles.
