FlightPath 2050 – The Inspiration for AeroGust
Funded by the European Union
FlightPath 2050 - Maintaining and extending industrial leadership
1. Competitive European aviation industry with a share of more than40% of global market.
2. Europe will maintain leading edge capabilities and jobs supported byhigh profile projects and programmes from basic research to full-scale demonstrators.
3. Streamlined and upgraded processes that address complexity andsignificantly decreased development costs (including a 50%reduction in the cost of certification).

Goals for 2050:
Funded by the European Union
Development of the AeroGust Project
• If market drivers lead to the adoption of more flexible materials andthe consideration of novel configurations, then the linear assumptionsof the current gust loads process will become unacceptable;
• The current process relies on steady wind tunnel data created fromthe final aerodynamic surface in the predicted cruise shape. Thismeans that gust loads come relatively late when the design optionshave been narrowed;
• The extension of aerospace technology to wind turbine design.

AeroGust AimTo investigate and develop improved simulation methods for gusts
5
AeroGust Objectives• To carry out investigations using CFD so that the non-linearities in
gust interactions are understood
• To create a gust loads process that does not require wind tunnel
data and hence reduces the need for wind tunnel testing
• To develop updated reduced order models for gust prediction
that account for aerodynamic and structural non-linearities at an
acceptable cost
