Fabricated Helicopter Transmission Housing Analysis

Abstract

The helicopter transmission housing study provides a transmission housing design superior to the conventional magnesium cast housing. The new design is a welded steel fabricated truss-like structure, corrosion resistant, and not susceptible to creep. The aircraft selected for this study was the U.S. Army CH-54B helicopter. The new fabricated truss-like housing was designed to be interchangeable with the present CH-54B magnesium main transmission housing. It meets all the interface and functional requirements of the cast housing design. Loads for flight and crash conditions, as well as stiffness criteria, were developed to permit structural analysis and comparison with the existing casting design.
