Synthetic Jet Actuator CFD simulation

A synthetic jet actuator is zero net mass flux device.
A synthetic jet is produced by the interactions of a train of vortices that are typically formed by alternating momentary ejection and suction of fluid across an orifice such that the net mass flux is zero. A unique feature of these jets is that they are formed entirely from the working fluid of the flow system in which they are deployed and thus can transfer linear momentum to the flow system without net mass injection across the flow boundary.

Insect flight - Caltech Dickinson lab


Insect flight - Caltech Dickinson lab
This video shows the flapping wing motion of a housefly captured by a three high speed cameras along x, y and d co-ordinates. This research is carried out by Dickinson lab at Caltech. To understand the insect flight and henceforth develop a more efficient Micro Air Vehicle (MAV).

Thrust Vectoring Kite

This thrust vectoring kite uses "Gimbal" mechanism for varying the thrust.
