Evaluation of measured-boundary-condition methods for 3D subsonic wall interference

Measurements on a simple aircraft model in both an appropriately sized and a relatively large, low-speed, solid-wall test section were used to analyse the accuracy and consistency of measured-boundary-condition (MBC) methods. For completeness, the classical method of images, with two different correction procedures, was also analysed. For the...

ARSPNSC: A method to calculate subsonic steady and unsteady potential flow about complex configurations

A new method ARSPSC is described for the calculation of steady and time-linearized unsteady subsonic potential flow about complex 2-D and 3-D configurations. The method belongs to the category of the so-called panel methods. Applications have been made to a 2-D oscillating flat plate, a 2-D multi-component airfoil with oscillating flap and a 3-D...
