High Angle of Attack Velocity Vector Rolls

IFAC Proceedings Volumes, 1994
Abstract This paper presents the design of a flight control system for performing the velocity vector roll maneuver at high angles of attack. A six degree of freedom model is developed, and the multiple-input multiple-output Quantitative Feedback Theory (QFT) robust control design method is used to treat both the inherent system nonlinearities and ...

Angle of Attack

Science, 2012
Chemistry In qualitative terms, chemists have become adept at predicting how reaction probabilities depend on the relative dispositions of two colliding reagents. For instance, if a reactive site is bounded by a large fragment and a small one, the collision partner is more likely to make it past the small one.

The angle of attack

IEEE Instrumentation & Measurement Magazine, 2001
The author considers the angle-of-attack compensator and the static pressure sensor. A true angle of attack is required to correct static and dynamic pressures. Static pressure is necessary to calculate altitude. Dynamic pressure is necessary to calculate speed. Sensing the angle of attack is crucial to correcting all sensed parameters.

Effect of Angle of Attack on Hypersonic

AIAA Journal, 1997
An experimental investigation of the effects of angle of attack on hypersonic boundary-layer stability on a ared-cone model was conducted in the low-disturbance Mach-6 Nozzle-Test-Chamber Facility at NASA Langley Research Center. Hot-wire anemometry diagnostics were applied to identify the boundary-layer instability mechanisms that lead to transition.

An optical angle of attack sensor

International Congress on Instrumentation in Aerospace Simulation Facilitie, 1990
A major source of transonic and supersonic wind-tunnel test data uncertainty are angle-of-attack-measurement errors caused by unknown sting and balance deflections under load. Since dynamic loads in pressurized or cryogenic wind tunnels generally exceed those in conventional low-speed atmospheric wind tunnels, the need to account for these distortions ...
