Some simple measurements of accelerations on board of a wide-body jet

A complaint of pilots flying in most simulators is that accelerations due to runway roughness are not simulated very well, and thus realism e.g. during a take-off run is lacking. As a first step towards improvement of motion simulation, actual responses to runway roughness have been measured to fom a base for compsürison. Thanks to the...

A digital turbulence model for the NLR moving-base flightsimulator. Part I

The turbulence signals as used until now at NLR were generated by linearly filtering Gaussian white noise. The filter was shaped to output the Dryden power spectrum. A major complaint of pilots about this model was that the turbulence was to continuous and that the intermittent property of real turbulence was lacking. At RAE-Bedford a...

Statische en dynamische eigenschappen van het bewegingsmechanisme van de vluchtnabootser met bewegende stuurhut (VMBS)

Het bewegingsmechanisme van de vluchtnabootser met bewegende stuurhut heeft vier graden van bewegingsvrijheid, nl. verticale translatie, rollen, stampen en gieren. In dit memorandum wordt voor iedere bewegingsmogelijkheid een overzicht gegeven van de prestaties en frequentiekarakteristieken.
