TESTS OF H-21C HELICOPTER ROTOR TRANSMISSIONS OPERATED WITHOUT OIL,

Abstract

The data in this report represents field observa tions of controlled damage tests of the forward, central and aft rotor transmissions of the H-21C ''Work Horse'' helicopter at Aberdeen Proving Ground, Maryland. Damage incurred by gears, bearings and other components of these trans missions, operating without oil for periods up to one hour, is presented. These tests are preliminary to actual gunfire tests to determine the vulnerability of the H21 power plant and gear trains to impacts by small arms. (Author)
