A Procedure for Inducing the Leans Illusion in a Hexapod Motion Simulator

Ground-based demonstration of spatial disorientation (SD) has been recommended for military as well as commercial pilot training. Although the leans illusion is the most common form of SD, no data exist yet of an effective ground-based leans procedure for a hexapod simulator. In this paper we describe the development of such a procedure and its...

Eigenmode Distortion Analysis for Motion Cueing Evaluation in Fixed-Wing Aircraft Simulators

The Eigenmode Distortion (EMD) analysis is a novel method for objective evaluation of simulator motion cueing fidelity, developed at Delft University of Technology. It expresses the distortions of the perceived motion cues in terms of the dynamic modes of a linear model of the vehicle and has been applied to assess rotorcraft simulations. This...

Eigenmode Distortion as a Novel Criterion for Motion Cueing Fidelity in Rotorcraft Flight Simulation

Eigenmode distortion (EMD) is a novel methodology developed to study the degradation of perceived vehicle dynamics as a result of motion cueing algorithms (MCA’s) applied in rotorcraft 2ight simulators. This paper brie2y introduces EMD and subsequently describes its application in a pilot-in-the-loop experiment conducted on the SIMONA Research...

Objective Inceptor Cueing Test for Control Loading Systems: Principle and Initial Design

Using iterated extended Kalman Filtering for estimation of a hexapod flight simulator motion state

The six degrees-of-freedom Stewart platform, or hexapod, is in widespread use in the flight simulation industry for the generation of motion cues that are representative of those experienced in actual flight. For closed-loop control of such motion platforms, but also to be able to objectively assess the quality of the generated simulator motion,...

DUECA - Data-driven activation in distributed real-time computation

Experiments and flight simulation programs for a research flight simulator can be considered as a combination of real-time distributed calculation processes. Current tools and architectures for implementing these processes are complicated to use and require considerable real-time programming skills. The created programs are not sufficiently...
