Adjoint Optimization for Hyperloop Aerodynamics
VehiclesThis work investigates how the vehicle-to-tube suspension gap governs compressible flow physics and operating margins in Hyperloop-class transport at 10 kPa. To our knowledge, this is the first study to apply adjoint aerodynamic optimization to mitigate gap-induced choking and shock formation in a full pod–tube configuration.

Efficient Aerodynamic Shape Optimization [PDF]
10th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2004 Since the present author first became involved in computational fluid dynamics, around 1970, the landscape has changed dramatically. At that time, panel methods had just come into use, and the world’s fastest super computer, the Control data 6600, had only 131000 words of memory (about 1 megabyte).

Analysis and optimization of a camber morphing wing model
International Journal of Advanced Robotic Systems, 2016 This article proposes a camber morphing wing model that can continuously change its camber. A mathematical model is proposed and a kinematic simulation is performed to verify the wing’s ability to change camber.
