| Venue | LT7A |
| Speaker | Prof. Frank Lu, University of Texas at Arlington, USA |
Biography
Professor Lu was raised in Singapore and earned his degrees from Cambridge, Princeton and Penn State. Upon obtaining his doctorate, he joined the University of Texas at Arlington where he has been ever since. His research areas focus in high-speed aerodynamics and aero-propulsion, with emphasis in shock/boundary-layer interactions and applications of detonations. He has authored or co-authored over 300 journal papers and presentations. The monograph Advanced Hypersonic Facilities published in 2002 was translated into Chinese in 2016. He currently serves on the editorial board of the Shock Wave Journal and Aerospace Science and Technology, and the Springer Shock and High-Pressure Phenomena book series. He had previously served as Editor-in-Chief of the AIAA Progress in Astronautics and Aeronautics book series and as AIAA Vice President of Publications. Professor Lu is a Fellow of AIAA, ASME and RAeS and a founding member of the International Shock Wave Institute.
Abstract
An ideal parametric analysis was performed by combining a waverider forebody generated by the osculating flowfield method and a second-order performance model for a rotating detonation engine. A sharp nose and a slightly convex forebody profile yielded the greatest pressure recovery and greatest installed engine performance. Engine performance improved with increasing Mach number, but propellant autoignition temperature limits may limit Mach numbers to less than 3.5.
