IVANHOE Installed adVAnced Nacelle uHbr Optimisation and Evaluation

A consortium of an SME, an industry, an R&D institute, and three universities with complementary skills will produce this result in close coordination with the topic manager in 36 months, asking for a grant of  € 3 514 834. 

 

Coordinator CHALMERS will provide the design envelope and safeguard thrust/drag performance. HIT09 and UNIPD will jointly implement a multi-objective optimization loop to identify optimal nacelle shapes and installation positions. TUB will validate the resulting design options with a high fidelity CFD code, complemented by a high fidelity wind tunnel experiment of a Deharde powered nacelle model in DNW’s High-Speed Tunnel. 

 

The project will advance the state of the art in nacelle design by smart use of various fidelity level aerodynamic modelling tools enabling fast iterations and down selection of nacelle geometries and locations. Wing/nacelle interference will be taken into account. This method will be validated by wind tunnel experiments with new and advanced wind tunnel models and measuring techniques.

 

The result of the nacelle optimization for a UHBR installation on the Common Research Model will be delivered in full compliance with the call. Moreover, IVANHOE’s will provide an improved design method, tools, and facilities for use by the European aviation industry for future aircraft projects, unlocking the full potential of CO2 reduction of UHBR engines while increasing competitiveness by reducing costs for design and testing.

  • The impact of interference effects caused by alterations in the pressure field due to the nacelle installation will be quantified for appropriate engine matching.
  • The physical mechanisms of the flows due to the nacelle installation will be characterized based on experiments and CFD simulations for nacelle pressure and exhaust shock fields.
  • The changes of the aft nacelle and exhaust behaviors with the installation at take-off conditions will be understood using CFD simulations.
  • Aerodynamic design rules to optimize the close-coupled 3D installation for advanced UHBR aft nacelles and exhausts will be improved and validated.
