Obliique-Wing Aircraft

The application of the eigensystem synthesis technique to place the closed-loop eigenvalues and shape the closed-loop eigenvectors has not been practical for active flutter suppression, primarily because of the availability of only one control surface (aileron) for flutter suppression. The oblique-wing aircraft, because of its configuration, provides two independent surfaces (left and right ail...

Modeling, simulation and analysis of a multi degree of freedom aircraft wing model

This paper presented methods to determine the aerodynamic forces that acton an aircraft wing during flight. These methods are initially proposed for asimplified two degree-of-freedoms airfoil model and then are extensivelyapplied for a multi-degree-of-freedom airfoil system. Different airspeedconditions are considered in establishing such methods. The accuracy of thepresented methods is verifie...

Building Intelligent Pilots for Simulated Rotary Wing Aircraft

a typical scenario involving Soar-based RWA IPs. 1. Abstract There are two RWA in the scenario, just behind the The Soar/IFOR project has been developing ridge, indicated by the contour lines. The other intelligent pilot agents (henceforth IPs) for vehicles in the figure are a convoy of "enemy" participation in simulated battlefield environments. ground vehicles  tanks and anti-aircraft vehicl...

Flow Field Study Over the Wing of a Fighter-Type Aircraft Model

An extensive experimental investigation to study the flow structure over the wing of a fighter type configuration model has been conducted. The model used for this study was similar to the High Alpha Research Vehicle (HARV) that has been used in various European research centers for studying its force and moment characteristics. Tests were conducted at two subsonic speeds and at low to moderate...
