The dynamics of rotor wakes and the behaviour of tip vortices have emerged as critical areas of investigation in rotorcraft aerodynamics. These phenomena underpin not only the performance and ...

Although helicopter aerodynamics involves the same forces that arise in airplane aerodynamics, these forces occur differently due to fluid flow dynamics across the aircraft. Helicopters take advantage ...

Tiltrotor aircraft are more susceptible to rotor flow instabilities than standard single-rotor or tandem-rotor helicopters, according to a computational fluid dynamic study conducted at the University ...

Helicopter safety researchers are to undertake formal analysis of the hazardous vortex ring phenomenon and the effectiveness of an alternative recovery and escape technique. The vortex ring state is ...

Recently the flow field around the Savonius rotor has attracted much attention, because the rotor performance is very sensitive to the flow pattern in and around the rotor. Most flow investigations ...

Recent research demonstrated that, although most wing shapes used today create turbulent wake vortices, wing geometrics can be designed to reduce or eliminate wingtip vortices almost entirely. In the ...
