Detached-Eddy Simulation (DES) is a hybrid technique proposed in 1997 as a numerically feasible and plausibly accurate approach for predicting massively separated flows. Since its inception the method has been applied to a range of configurations including simple shapes such as cylinders, spheres and aircraft forebodies, in addition to complex geometries including fighter aircraft. The accuracy...

In order to achieve sub-meter accuracy for the positioning of a CF-188 jet fighter (Canadian version of the F-18) under 360 degree rolls, two GPS antennas mounted on top and under the aircraft fuselage are used. The two receivers are cross-linked through the use of a common oscillator and the continuous exchange of position, velocity and clock information to accelerate satellite acquisition dur...

A common feature of many aircraft configurations is that the actuation mainly effects the moments, and thereby the angular accelerations, whereas the desired normal acceleration is achieved by adjusting the location of the velocity vector in body coordinates. Thus, the main desired effects of the actuators appear after one integration, and if the actuators have dynamics the effect of the primar...

ScMf.r^ A review of lighter aircraft development programs over the pas t.three decades Indicates a trend of increasing emphasis on the considera tion of static aeroe las tic effects. While early concerns addressed only the impact on air vehicle structural integrity, current design philosophy recognizes and addresses aen jelastlclty as a primary design parameter affecting structural optimiza tio...

Abstract The high operational cost of aircraft, limited availability air space, and strict safety regulations make training fighter pilots increasingly challenging. By integrating Live, Virtual, Constructive simulation resources, efficiency effectiveness can be improved. In particular, if constructive simulations, which provide synthetic agents operating vehicles, were used to a higher degree, ...

The possibility of extracting large amounts electrical power from turbofan engines is becoming increasingly desirable an aircraft perspective. consumption a future fighter expected to be much higher than today’s aircraft. Previous work in this area has concentrated on the study extraction for high bypass ratio engines. This motivates thorough investigation potential and limitations with regards...
