Wing Analysis Version 2.1 - Analysis of multisection wings, providing (now on the AMA District-II server):

Mean Aerodynamic Chord calculation
shear and bending-monent calculation
lift distribution (i.e. lift-roll)
Cd/drag distribution specific to an airfoil (UIUC database)
allows different airfoils at each panel break

RCSD On-Line Index

For now, this is the home of the RC Soaring Digest on-line search engine. The real work has been done by Lee Murray, LJM Associates, in keeping the RCSD index up-to-date with each month's artcles. Below are links to the various files used to provide the on-line search capability.
