There is great interest in small aircraft known as Micro Air Vehicles and mini Unmanned Air
Vehicles due to the wide range of possible applications. This article reviews recent work that …

The vortex dynamics of thrust and lift generation for periodically plunging airfoils and finite
wings at low Reynolds numbers is reviewed. Effects of vortex lock-in phenomenon, leading …

We investigate the forces and unsteady flow structures associated with harmonic oscillations
of an airfoil in the streamwise (surging) and transverse (plunging) directions in two …

The effect of a chordwise flexible aft-tail of a rigid heaving aerofoil on the dynamical
transitions of the trailing-wake is studied here. The two-way coupled fluid–solid dynamics is …

A novel gust generator was developed to study the interaction of wings with vertical gusts of
controllable interaction time with magnitudes up to 30% of the freestream velocity at low …

The unsteady aerodynamics of three plunging wings with different planform shapes was
investigated in water tunnel experiments by means of force/moment and three-dimensional …

THE prevalence of small uncrewed air vehicles (sUAVs) has exploded in recent years in
both the military and commercial space. While many current sUAVs being developed are of …

It has previously been shown that, at high Strouhal numbers, oscillating airfoils can produce
deflected jets that can create very high lift-coefficients for otherwise symmetric scenarios …

A frequency response approach is taken to model unsteady aerodynamics resulting from
plunging oscillations of an airfoil. The oscillations range covers high angles of attack (up to …

A lift formula for a wing in a rectangular control volume is given in a very simple and
physically lucid form, providing a rational foundation for calculation of the lift of a flapping …
