Product-Improvement Test of OH-6A Helicopter Tail-Rotor Balancing Equipment.

Abstract

Maintenance problems associated with high-frequency vibrations in the OH-6A were encountered in the reliability test program and in tactical use by field units. These vibrations frequently were attributed to improper balance of the tail-rotor assembly. Since this assembly could not be balanced using equipment presently in the Army inventory, the LOH Project Manager requested that the airframe manufacturer develop suitable balancing equipment. The tail-rotor balancing equipment consists of an accelerometer with mounting bracket, a vibration analyzer, a protractor, and electrical cables, which are contained in a fiberglass carrying case. These items are used in conjunction with the blade-tracking strobe light assembly. Power required for equipment operation is 24 volt's direct current which is obtained from the auxiliary fuel tank connector in the aircraft.
