Abstract : The results of a program conducted to investigate the low-temperature characteristics of rotors equipped with elastomeric bearing are reported. An all-elastomeric, two-bladed main rotor and a production tail rotor, with elastomeric bearings installed in the flapping axis, were tested on an OH-58 A helicopter. Tests were conducted at temperatures of 70F, 0F, -25F, -45F, -55F, and -65F. Two main rotor pitch-change bearing configurations were evaluated. The first was fabricated from natural-rubber elastomer and the other from broad-temperature-range elastomer. (Author Modified Abstract)
