Aeroelastic control systems represent a critical intersection between aerodynamic theory and structural dynamics, addressing the complex interactions that give rise to flutter – a self-excited ...
Panel flutter is a dynamic aeroelastic instability of external skin panels exposed to supersonic airflow. Coupled aeroelastic analysis reveals that attaching an acoustic black hole (ABH) structure to ...
Modern CFD simulations provide detailed insights. However, especially in the transonic regime, they face physical and modeling limitations. Nonlinear interactions between shock waves and blade ...
Boeing has completed aeroelastic flutter testing and ground effects testing with its first two 787 test aircraft. This clears the way for the formal US Federal Aviation Administration certification ...
Winglet manufacturer Aviation Partners has completed a test flight with a Hawker 800 featuring a new winglet installation that was tweaked to prevent aeroelastic flutter. The original Aviation ...
In a collaboration between the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR, Göttingen, Germany) and the Technical University of Munich (TUM, Munich, Germany), researchers ...
The aim is to make aviation in Europe climate-neutral by 2050. An important part of this is reducing the drag of future aircraft, with the wings playing a major role. The wings not only generate the ...
ABSTRACT A mathematic rotating blade model is introduced in conjunction with periodic time-varying aerodynamic load, which is described by Beddoes-Leishman dynamic stall model. The consequent ...
