The concept is that the flow around the wing is formed as unsteady longitudinal vortex flow.Shape of leading and trailing edges of the wing should be of a specific vortex generating shape, which isoptimized for each airfoil type. In flight tests of the UA... see more

To fulfill the objective of a predictive tool for rotorcraft, comprehensive analysis (CA) needs to be capable of providing both accurate and time-efficient predictions of rotor air loads and structural loads. The more recent methodology based on comprehen... see more

Using the effect of wingtip vortex from a leading aircraft, the formation flight of unmanned combataerial vehicles (UCAVs) can accomplish various tasks with much more efficiency. Combined withthe sliding mesh technique, this paper investigates a computati... see more

A method is presented to model the incompressible, attached, unsteady lift and pitching moment acting on a thin three-dimensional wing in the time domain. The model is based on the combination of Wagner theory and lifting line theory through the unsteady ... see more

The experimental data for a Cbladed soft-inplane hingeless main rotor is used to validate a comprehensive aeroelastic analysis. A finite element model has been developed for the rotorblade which predicts rotating frequencies quite well, across a range of ... see more

A commercial CFD solver is used to simulate the unsteady aerodynamics performance of rigid and flexible wing airfoils for a high-performance jet trainer aircraft. The configuration used in the computational analysis is NACA 64012. In the numerical simulat... see more

Circular cylinder has a strong  adverse pressure gradient. When a fluid flows around the circular cylinder, it will produce aerodynamics force. One of them is  the drag force which strong enough. Hence, control of flow need to reduce the drag fo... see more

Experimental investigation on a novel VTOL aircraft named \Anuloid "has been carried out to assess its aerodynamicsperformances. The study focused on two main aspects: the analysis of the Coanda eect on the 1:20 scaled modelwithout cross- ow and the aerod... see more

The unsteady flow behavior and time-dependent aerodynamic characteristics of the flapping motion of a bird’s wing were investigated using a computational method. During flapping, aerodynamic interactions between bird wing surfaces and surrounding flow may... see more
