Results of Helicopter Flight Tests of a Circumferential Carbon Oil Seal

Abstract

TWO samples of a circumferential carbon seal design underwent flight tests in UH-1 and AH-1 type helicopters. One sample was tested at Bell Helicopter's flight test facility and one sample was tested at Fort Rucker, Alabama. Both seals operated successfully with no reported leakage for a total of 435 hours. The seal tested at Bell Helicopter accrued 179 hours of successful operation in an AH-1G helicopter, including cold-weather testing down to -65F. The seal installed at Fort Rucker operated for 256 hours and at the time of this report was still operating satisfactorily.
