Project description DEENESFRITPL Solving the challenge of compound rotorcraft aerodynamics and aeroacoustics Unravelling the complexities of aerodynamics in compound rotorcraft is a huge challenge for today’s engineers. Analysing the intricate aerodynamic phenomena of compound rotorcraft is crucial for developing more efficient and innovative rotorcraft designs. The EU-funded CA3TCH project aims to revolutionise aerodynamic design practices. Specifically, it will consider the full external aerodynamic behaviour, including aeroacoustics. This digital wind tunnel approach allows for high-fidelity aerodynamic investigations, coupling structural simulations and flight mechanics. The project will thus establish simulation technology that supports the efficient design and development of RACER, enabling a detailed examination of aerodynamics and aeroacoustics at different flight states. Overall, CA3TCH will significantly extend the applicability of helicopter simulations, answering critical questions regarding performance optimisation, safe operation, flight mechanics, and handling qualities. Show the project objective Hide the project objective Objective CA³TCH considers the full external aerodynamic behaviour of a compound rotorcraft to be developed. Aerodynamics -- and aeroacoustics as well -- have to be investigated by full-featured simulations including coupling to structural simulation and flight mechanics. This “Digital Wind Tunnel” approach examines the performance of the projected aircraft long before first hardware exists. This allows to differentiate various alternatives as well as to drive the design process according to the detailed analysis of the flow field.The primary goal of the project is to establish the simulation technology required to support productively the aerodynamic design and development of LifeRCraft, from rough estimates to detailed design and analysis at different flight states, until the point of first flight. Additionally, beyond the specific economic application to this compound configuration, the project will significantly improve the ability of helicopter simulations to answer particular questions in the development process, regarding aerodynamic or aeroacoustic optimisation, flight mechanics properties and even handling qualities to a certain extent. Publication and dissemination efforts will spread this enhanced capability to related areas, from fixed wings to wind turbines, just to name a few.CA³TCH starts with some necessary tool enhancements and continues with the application to increasingly complex, detailed and refined configuration models. Afterwards, not only large-scale simulations will be run, rather a very large part of the project´s added value consists of the rigorous analysis and interpretation of the results obtained.
