SPIV measurements of the flow field associated with stall flutter on the flexible wing

Flow Control of Flexible Wing Structures Project

In order to enhance aircraft efficiency designers are increasingly utilizing lightweight, high aspect ratio wing designs. This is because lower weight means less energy is required to keep the aircraft aloft and high aspect ratio wings have lower induced drag. These two factors combine to enable high efficiency vehicles. These...

Dual-Throat Thrust Vectoring Nozzle Experiment

Dual-Throat nozzles provide a promising means for thrust-vectoring in modern aircraft systems without any moving parts. As shown in the schlieren photograph, from the experiments at the CU Experimental Aerodynamics Laboratory, a secondary mass injection jet is used to bend the core flow in the dual-throat region, producing a vectoring of the main jet as it exits the assembly.
