Application of NLR's numerical simulation methods to the transonic potential flow about oscillating wings

unsteady and quasi-steady aerodynamic loads in the transonic flow domain have been obtained from NLR's numerical simulation methods for transonic potential flow. The unsteady results have been obtained with the time-linearized finite volume method FTRAN3, embedding a so-called field panel method which accounts for proper radiation of signals...

Application of time-linearized methods to oscillating wings in transonic flow and flutter

Unsteady aerodynamic loads in the transonic domain have been obtained with time-linearized methods in which a so-called field panel method is embedded which accounts for a proper radiation of signals towards infinity. The methods are used to predict the unsteady loads and first harmonic pressure distributions on an airfoil and a transport type...
