Virtual Integrated soLutions for future Demonstrators and products

Purpose and goal:

Geometries and aerodynamic models will be produced for the low pressure turbine, nacelle, fan blades, low pressure compressor and duct between compressors in a turbofan engine. Method development will be done with respect to noise analysis of a modern turbofan engine. Furthermore, methods will be developed for composite design of fan blades and nacelle.

The project aims to maintain and further develop collaboration and knowledge sharing between industry and universities within the aerospace sector in Sweden. Expected results and effects:

The project is expected to increase the maturity level of a number of components in the turbofan engine developed in the turbomachinery cluster: the fan blades, nacelle, low pressure compressor, ducts and low pressure turbine. Geometries and boundary conditions for these components can be used to provide relevant context for other research projects. The aeroacoustic methods developed in the project can be used to design low noise aircraft engines in the future.

Approach and implementation:

Follow-up of the project work will be done at quarterly meetings and additional meetings will be held when needed. GKN coordinates the project, performs aerodynamic design of the fan blades, nacelle, low pressure compressor (LPC) and the duct between compressors. Furthermore, GKN develops methodology for noise assessment of a turbofan engine.

Lund University will produce an aerodynamic design of a low pressure turbine and the first stage in the LPC. Chalmers will develop a system model for noise estimation and KTH will develop methods for design of carbon fibre fan blades and nacelle.
