Project description:

Advancing research and design of aircraft wings

It has long been considered that the easiest way to improve aerodynamic efficiency and performance of an aircraft is to increase the aspect ratio of its wings, which in turn impacts the induced drag. The EU-funded U-HARWARD project aims to investigate the use of innovative aerodynamic and aeroelastic designs in a multi-fidelity multi-disciplinary optimal design approach in order to facilitate the development of ultrahigh aspect ratio wings for large transport aircraft. This will be done largely through a design study to help determine the potential gains of different wing configurations depending on cargo weight.

Objective:

U-HARWARD will consider the use of innovative aerodynamic and aeroelastic designs in a multi-fidelity multi-disciplinary optimal design approach to facilitate the development of Ultra-High aspect ratio wings for large transport aircraft. A conceptual design study, building on the current state of the art, will perform trade-off studies to determine the potential gains of different wing configurations and loads alleviation concepts in terms of aerodynamics, weight, noise, fuel-burn and range. Scaled model wind tunnel tests will be used to validate parametric variations in the aerodynamic and acoustic characteristics. Starting from a reference aircraft, the preliminary design of the best candidate configuration will be completed and the estimated gains validated using high fidelity tools and a larger scale aeroelastic test.
