The proposal described the methodology to be used for engine installation design optimisation in heavy helicopters. Specific objectives of such activity were the following:

• to set up of a comprehensive and fully automatic optimal design tool, integrating the software suitable for engine installation analysis and in-house multi-objective optimization algorithms already developed by the applicant;
• to apply such tool for the efficiency improvement of engine installation components based on the boundary conditions given by the manufacturer, in order to achieve a significant reduction in the engine installation losses.
