Project Objectives

1. Design and develop short and slim nacelle designs for the UltraFan® type engine applying a novel philosophy of optimising nacelle drag across the mission conditions.

2. Apply the latest optimisation techniques in the multi-objective and multi-point design space to generate candidate geometries

3. Down-select optimum designs for experimental validation

4. Develop and expand existing experimental test techniques to assist in verification of the identified design optima

5. Design, manufacture and test a family of optimum geometries to prove the effectiveness of the new design philosophy

6. Determine the suitability of the proposed nacelle designs by simulation of the installed configurations (full-scale CFD investigation and WTT feasibility study)

7. Validate design and computational methods for compact nacelle configurations using improved experimental data

8. Establish design guidelines for new nacelle configurations based on a synthesis of the computational and experimental data.
