This article summarizes the ability of CHARM+AGDISP to predict the drift and deposition of sprays released from rotary wing unmanned aerial vehicles (UAVs). This predictive capability results from merging algorithms for spray transport, as found in A

The aim of this research was to demonstrate that a free wake hover performance prediction code could be coupled to a numerical optimization algorithm. The hover code, dubbed EHPIC (evaluation of hover performance using influence coefficients), uses a
