The ZONA Aeroelastic Model Simulator (ZAMS) is an ActiveX control developed to run under the IADS real-time and post-test display and analysis software developed by Symvionics, Inc.† ZAMS is used to display the aeroelastic response (i.e., motion) of an aircraft during flight test or during playback of recorded flight test data. ZAMS can provide flight test engineers within the mission control room the ability to rapidly visualize, in a near real time capacity, aircraft structural oscillations when the aircraft is excited by:

Based on aircraft accelerometer responses obtained in IADS during flight test, ZAMS uses these accelerometer responses to compute/display the aeroelastic deformation of the structure. A few seconds of flight test data are buffered by ZAMS to perform the required computations.

ZAMS includes options such as display of pitch/roll rigid body motions, amplification of computed displacements, display of control surface motions, zero-displacement "node-line" tracking to characterize the type of aeroelastic motion, as well as sensor information plots to visually verify the adequacy of the computed sensor displacements.
