A simplified and approximate technique for scaling rotorcraft control inputs for turbulence modeling

An approximate and simplified approach for scaling rotorcraft control inputs used in the modeling and simulation of flight in atmospheric turbulence is presented. The scaling allows the use of empirically derived "gust-filters" obtained for one rotorcraft to be scaled to another, different vehicle. The approach is elementary in nature and can be considered only to be a "first-order" solution to this scaling problem. Examples of employing the technique are provided using models of four rotorcraft in hover mode.
