A Modification to the Free Floating Extensible Cable Sytem Computer Model (FF2E) to Consider Lift and Drag Forces on Intermediate Bodies

Abstract

The Free Floating Extensible Cable Program (FF2E) was modified to account for velocity dependent lift and drag forces on bodies in a drifting cable system. Lift forces from a small body are shown to significantly affect the steady state geometry of a sonobuoy. The program modification allows tables of empirical lift and drag data to be input to the program and provides an interpolation scheme in a subroutine.
