A leading-edge root extension (LERX) is a small fillet, typically roughly triangular in shape, running forward from the leading edge of the wing root to a point along the fuselage. These are often …

NASA conducted extensive investigation of the phenomenon using its F-18 High Alpha Research Vehicle (HARV). During testing, smoke was injected into the LEX vortex making it possible to …

You're correct that the leading edge extension (LEX) plays an important part in increasing the maximum angle of attack of the Hornet/Super Hornet. The LEX basically forms a vortex above …

f-18 安装了 4 余度数字式线传飞控系统，是首个安装这种系统的生产型飞机。 飞控计算机根据操纵杆和脚蹬输入的数据来控制各个操纵面的偏转量，不允许飞行员飞出超出限制的动作。

To alleviate the vibration problem the aircraft manufacturer developed the 'LEX fence'. This is a flat trapezoidal plate standing perpendicular to the LEX upper surface and aligned parallel to …

1992年9月1日 · Flow-field measurements on the leading-edge extension (LEX) of the F-18 High Alpha Research Vehicle (HARV) were obtained using a rotating rake with 16 hemispherical …

2023年11月15日 · LEVCON is designed to operate on the same principles as LERX, but its aim is to generate lift-augmenting vortices, i.e., vortex lift, at higher angles of attack than LERX. To …

The unsteady pressures acting on the vertical tails of a full- scale F/A-18 fighter aircraft were studied to gain a better understanding of tail-buffet loads that frequently occur on fighter...

The F-18 incorporated a quadruply-redundant digital fly-by-wire flight control system, the first of its kind to be installed in a production aircraft. It works by having stick and rudder inputs being …

LERX were first used on the Northrop F-5 which flew in 1959 and have since become commonon many high performance combat aircraft. The F/A-18 Hornet has especially large examples …
