The Drag and Shape of Control Lines in Flight
This note documents (briefly) the development and implementation of the methods used computing for a control–line model aircraft the drag and shape of the lines in level flight. Wind and pilot technique (lead/lag) are considered. The wind is assumed to have constant velocity and direction and the pilot flies so as to make the handle rotate in a circle about a fixed point on the ground. The methods developed here have been implemented in a computer code in which the effect of Reynolds number on drag is accounted for as is a nonstandard atmosphere.
