Vibration
8.5
Equipment tested to DO-160C Category N,
using vibration test curve N for rotor wings.
Critical frequencies for sinusoidal test,
curve N:
X axis:
54.66Hz @ 7.67G
61.63Hz @ 8.89G
359.06Hz @ 2.13G
1952.6Hz @ 2.14 G
Y axis:
136.7Hz @ 3.71G
195.4Hz @ 10.28G
2000Hz @ 2.34G
Z axis:
128.44Hz @ 7.71G
201.95Hz @ 2.85G
1536.3Hz @ 4.63G
1946.8Hz @ 6.86G
No changes in critical frequencies were
observed in all three major test axes.
Note: Test conducted with ruggedized
mounting tray, P/N 805-10870-003.
