Notes:
Characteristics and mechanism of twin-vertical-tail buffet response on airplaneconfiguration with wing root leading edge extension (LEX) were studied by both experiment andcomputation. Low-speed wind tunnel experiments were carried out to measure the root bendingmoment and tip acceleration of vertical tail. Vortical flow patterns were visualized via laser lightsheet technique. Three-dimensional computation was performed to solve the unsteady Eulerequations on rigid model. The results indicate that (1) bursting of vortices emanating from LEX is themain source of twin-vertical-tail buffet; (2) the Euler equations is able to predict the generalcharacteristics of vertical-tail buffet response reasonably
