Abstract: The development of extremely high performance aerospace power transmissions will be a very interesting technological challenge for the next future. In gear design for high power transmission, desirable characteristics, such as low noise emissions, low vibrations, minimum size, minimum maintenance cost, but most of all minimum weight can be obtained through the development of innovative layouts. However, most of the rules based on experimental data, by which common gearns are calculated and verified, are not applicable to transmissions whcih can be defined unconventional in terms of geometry and/or operation conditions (high power, high rotating speed, low weight). In these cases, numerical simulations can be performed bu using FEM codes. The objective of this work is to describe how interated CAD/FEM tools can be employed to develop procedures for the static performance analysis of unconventional gears. In the paper, potential characteristics, limits and capabilities of simulating real system behaviours are discussed.
