The multi-purpose Desdemona simulator recently installed at TNO will definitely push the limits of movement simulation. Desdemona is a movement simulator, disorientation trainer and advanced research lab, all in one. This simulator – unique to the world – can be used for both research and the simulation of complex situations that may occur during flight, driving or even sailing.

Most flight and driving simulations take place in standard hexapod simulators, but these do not allow the exact simulation of really complex aircraft movements or extreme vehicle movements like off-road driving. Desdemona (DESoriëntatie DEMONstrator Amst) is a simulator offering an extended movement envelope. It is the result of a collaboration between TNO and the Austrian AMST Systemtechnik. Desdemona combines the possibilities of both the hexapod and the centrifuge. The Desdemona cabin with modular layout is mounted on a fully gimbaled system that is able to rotate around any conceivable axis. The system as a whole allows 2 metres of vertical movement, combined with 8 metres along a horizontal sledge. The sledge itself is able to spin as well. Centrifugation enables Desdemona to generate constant G-forces up to a maximum of 3 G.

Always the right motion cueing

A motion cueing algorithm translates the movement envelope of an aircraft into the less extended corresponding movement envelope of the simulator. Desdemona is based on Spherical Washout, our own innovative motion cueing algorithm based on the proven advantages of the conventional hexapod algorithms and Dynamic Flight Simulation. Desdemona was originally designed for spatial disorientation research and training, for human movement perception and motion cueing R&D, and for advanced flight simulation. However, Desdemona allows a much wider use, e.g. in military, civil and small aviation, space programmes, shipping and the automotive industry. Other organisations such as the pharmaceutical industry and manufacturers of roller coasters will definitely also benefit from the opportunities offered by Desdemona.
