Numerical Research on the NS-SDBD Control of a Hypersonic Inlet in Off-Design Mode
Aerospace, 2022 The overall performance of a scramjet inlet will decline while entering off-design mode. Active flow control using nanosecond surface dielectric barrier discharge (NS-SDBD) can be a novel solution to such inlet–unstart problems.

Modeling of Unsteady Aerodynamic Loads [PDF]
AIAA Atmospheric Flight Mechanics Conference, 2011 Time-accurate solutions of the Euler or Navier-Stokes equations are still nowadays a computationally expensive approach for applications where a magnitude of parameters has to be investigated. This work focuses on flight dynamics-related studies. The generation of several low-order models for the evaluation of unsteady and non-linear aerodynamic loads ...
