The objective of the transmission modularization analysis was to develop a methodology to evaluate helicopter transmission modularization and to demonstrate the feasibility, methods, design criteria, and cost effectiveness of modularization. A U.S. Army CH-54B helicopter was selected for the analysis and designs were completed for transmissions with seven, six, four and three modules. A mathematical model was derived that calculated the cost and performance characteristics of a helicopter with a modularized transmission. A computer program was written to implement the mathematical model.
