HLH Drive System

Abstract

This report summarized the total Heavy Lift Helicopter Drive System Advanced Technology components (ATC) program. The program included the establishment of design criteria; the development testing of advanced technology components; the integration of these components into flight-weight, full-scale HLH transmissions; and the testing of the transmissions. The aft rotor and engine combining transmissions with associated drive shafting were designed, built, and tested. The transmission required to power the forward rotor was studied in the ATC program and was detail designed and fabricated under a later HLH prototype program.
