Abstract:

Limited static tests on damaged scale-model Heavy Lift Helicopter HLH plus or minus 45 degree glassplus or minus 5 degree graphite drive shaft sections at 150 deg F indicated that the shafts are not capable of meeting the design requirement of the HLH. Low-energy impacts ball drops produced catastrophic brittle failure of the graphite material. Ballistic damage was localized to the impact area but resulted in a strength reduction factor of approximately 1.75.
