Hua-Dong Yao is a researcher at the division of Fluid Dynamics at the Department of Mechanics and Maritime Sciences and will be the coordinator for IVANHOE with a budget of EUR 3,5 million. IVANHOE is an abbreviation for Installed advanced nacelle UHBR optimization and evaluation. The project is targeting to promote the achievement of the high-level environmental objectives that are aimed by Clean Sky 2 and ACARE SRIA to reduce carbon dioxide, NOx and noise. Hua-Dong Yao explains that aircraft nacelles are the housings of engines. A way of installing nacelles is to use pylons holding them under wings.
“Installation positions and nacelle shapes can significantly influence the propulsion efficiency and, consequently, fuel consumption and emissions. The IVANHOE project aims to find out the best position and nacelle shape for ultra-high bypass ratio UltraFan engines” says Hua-Dong Yao.
Chalmers’ researchers will contribute to the design, optimization and simulation of engine cycles and nacelles, improved design method, tools and facilities for the development of future aircraft in the European aviation industry are the expected results.
Chalmers is also a partner in SUBLIME where the researchers will develop a new method to design boundary layer ingesting engines. Hua-Dong Yao is very pleased to get two EU projects accepted at the same time even if that means that the challenges also will be doubled. He feels cautiously optimistic.
“I hope that these projects can strength our competencies of aeronautics and fluid dynamics in both fundamental and engineering aspects. We will also extend the collaboration with Rolls Royce” says Hua-Dong Yao.
