Abstract
Flight testing using a designed experiment was used to model pitch damping in the longitudinal short-period mode of an aircraft. Multi-step elevator maneuvers were flown at different angles of attack and power levels on an electrically powered, propeller-driven UltraStick 120 remotely controlled model A Central Composite Response Surface Design was used to select angle of attack and power levels for each maneuver. During post flight analysis it was discovered that power was not measured correctly for this purpose so advance ratio was selected as a replacement factor. Parameter estimation results for each maneuver were modeled globally using a single response surface. This experiment allowed global modeling of the pitch damping to be performed from just a few flight test maneuvers. Identified global models of pitch damping are plotted against angle of attack and power (or advance ratio) in a surface response plot, for nonlinear piloted simulations and for flight test data.
