Do old researchers have more wisdom than young ones?
Prof. Kielb will give a semi-serious talk on younger versus older researchers. Old researchers typically have years of experience, more wisdom, buy less knowledge of the latest computational and experimental methods. Young researches are typically the opposite. This talk reviews Prof. Kielb’s career experiences and gives suggestions to new researchers in areas such as conducting research and presenting the results.
Professor Robert Kielb
Thomas Lord Mechanical Engineering and Materials Science Department
Robert E. Kielb specializes in turbomachinery aeroelasticity. He has over 50 years academic, industrial and government research laboratory experience in turbomachinery propulsion. This consists of 8 years with the U. S. Air Force, 10 years with NASA Lewis Research Center, 12 years with GE Aircraft Engines as Manager of Aeromechanics Technology, and 22 years with Duke University. He has also been an Affiliated Professor at the Swedish Royal Institute of Technology (KTH) since 2008. He is also Director of the GUIde Consortium (12 companies, 5 universities and 2 government organizations) and was the Duke Coordinator for the EU-funded THRUST MEng Program. His primary experiences are: 1) developing and implementing state-of the art mechanical and aeromechanical design technologies; 2) directing blade design, manufacture, and test; 3) initiating and executing R&D programs to support needed technology improvements, and 4) coordinating research programs among government, industry and universities (GUIde). He has authored or co-authored over one hundred technical papers, is a recipient of the GPPS’s Lifetime Achievement Award, ASME’s Melville Award and R. Tom Sawyer Award, and has presented invited lectures worldwide. Prof. Kielb is a Fellow of the ASME and was a Chair of the Board of Directors of the International Gas Turbine Institute, serving on the Board for 6 years. He has also served as Technical Program Chair for ASME Turbo Expo ’96, Chair of the ASME Structures and Dynamics Committee, and Associate Editor of both the Journal of Turbomachinery and Journal of Engineering for Gas Turbines and Power

Fan-installation interaction in future propulsion systems
The talk will focus on how new installations are critical and how unsteady CFD can be applied to reveal the key aerodynamic interactions and to improve the design. In new configurations of propulsion system the fan and installation are highly coupled and need to be analysed and designed together rather than treated as isolated components. Unsteady CFD is a key tool that enables complex flow interactions to be resolved and can provide detailed understanding of the system performance and the off design operability. This talk will consider a range of future propulsion system configurations including low pressure ratio fans with short intakes, distributed boundary layer ingesting propulsors, aft fuselage fans, and counter-rotating open rotors. In each case, full annulus unsteady CFD of the complete system has been applied. The results reveal the important flow features influencing performance and operability limits. Some key findings will be presented and areas for further research proposed.
Professor Cesare Hall
Professor of Aerothermal Engineering
Cesare Hall is a Professor in Aerothermal Engineering in Cambridge University and an Engineering Fellow in King’s College, Cambridge. He completed his PhD in 2002 in the field of jet engine operability. He then joined the Fan Aerodynamics group of Rolls-Royce plc working on computational methods to assess jet engine fan stability and performance. In 2004 he joined the Silent Aircraft Initiative, researching novel future concepts for low-noise propulsion systems. In September 2005 he was appointed as a lecturer in Turbomachinery at the Whittle Laboratory within Cambridge University Engineering Department. He has since been developing research into reduced emissions propulsion systems, airframe-engine interaction and the environmental impact of aviation.

Accelerating Sustainable Propulsion and Power through Modeling and Simulation
Aviation and Energy sectors have been challenged to drastically reduce their carbon footprint in the next decade. Several technologies such as hybrid-electric propulsion, highly compact-core Gas Turbine engines, and low carbon fuels provide a great potential. Though, the primary challenge for all these concepts is the longer timeframe of the technology maturation. Modeling and simulation can substantially accelerate such technologies to be production ready. This talk will detail the role of model-based engineering and simulation from exploring radically different ideas to product certification. Real-world examples will be highlighted illustrating how this approach is helping the industry meet the ambitious net-zero targets.
