Preliminary Validation of the Wind Tunnel Based Flight Control System Evaluation Method
MATEC Web of Conferences, 2018 As mathematical models of aircraft aerodynamics and rudder loadings always have to be built in the hardware-in-the-loop simulation, wind tunnel based flight control system (FCS) evaluation methods were proposed in order to test and evaluate the flight ...

Aerodynamic Test of AGARD-B Model at Mach 10 in Arc-heated High-Enthalpy Wind Tunnel
气体物理The test capacity of hypersonic equipment is crucial to the development of hypersonic technology. However, the maximum Mach number simulated by conventional hypersonic wind tunnel is less than 10 currently due to the insufficient heater capacity ...

The Measurement of Radar–Plasma Signatures in a Hypersonic Shock Tunnel: Simulation and Experiment
IEEE Transactions on Aerospace and Electronic Systems, 2023 The plasma sheath that forms around a body in hypersonic flight can change the radar signature substantially. The prediction of radar–plasma signatures, however, is complex, since it incorporates aerothermodynamics and electromagnetics and requires a ...

Control Effectiveness of Vortex Generators in High‐Speed Flows in Off‐Design Conditions
PAMM, Volume 26, Issue 1, March 2026.ABSTRACT In aerospace transportation and propulsion systems, shock‐induced flow separation has strong detrimental effects on the aerodynamic behavior and performance. To alleviate these effects, separation control is necessary. A commonly pursued approach uses vortex generators (VG) of different design to increase the momentum transfer within the ...
