Fan Alternatives for Next Generation engines 2 (FANG2)

Research Project, 2023 – 2024

Purpose and goal
The project Fan Alternatives for Next Generation engines 2 aims to give GKN Aerospace och Chalmers input to design components for energy efficient and environmentally improved aircraft engines. FANG2 develops methods to calculate the geometry and construction of low pressure system in future turbofan engines. The focus is to balance, on the one hand, size, weight and cost of the propulsive fan and the components which support it, and on the other hand, its aerodynamic efficiency and ability to convert shaft power to thrust.

Expected results and effects
Methods to evaluate low pressure systems for future commercial turbofans, in particular stall margin and aerodynamics. A case study for a mid range single aisle aircraft including assessment of the effect of varying engine diameter. Comparison between 3D aeroanalysis and correlation methods for fan function. Optimal specific thrust and fan pressure ratio as well as impact of weight, nacelle drag and component efficiency on the fan design parameters. The project will support pre-studies of components for next generation engines with requirements and environmental conditions.
