Distance-Fields-Over-Grids Method for Aircraft Envelope Determination

On-Line Safe Flight Envelope Determination for Impaired Aircraft

The design and simulation of an on-line algorithm which estimates the safe maneuvering envelope of aircraft is discussed in this paper. The trim envelope is estimated using probabilistic methods and efficient high-fidelity model based computations of attainable equilibrium sets. From this trim envelope, a robust reachability analysis provides the maneuverability limitations of the aircraft thro...

A statistical method for electromyographic envelope determination

The information extracted from electromyographic signals can provide researchers with a number of useful information to study muscle activity. Various techniques can be found in the literature to perform such analyses. However, most of them, when dealing with dynamic contractions, for instance, do not take adequate care when highlighting the correct window of the collected signal. Hence, the re...

Computation of Aircraft Flow Fields by a Multigrid Euler Method

An algorithm for computing transonic flow fields about fighter-type aircraft is described in the paper. The compressible Euler equations are solved numerically using a vertex-based, finite volume multigrid scheme. The space around the aircraft is discretized with a single-block H-0 mesh which is generated by the union of separate Omeshes around successive cross sections of the aircraft. The dis...
