Active Flow Control of NACA 0012 airfoil using Sawtooth Direct Current Augmented Dielectric Barrier Discharge Plasma Actuator

Ravi Sankar Vaddi, Charles Sota, Alexander Mamishev +1

Dielectric barrier discharge (DBD) plasma actuators are an attractive option for separation control, lift enhancement, and drag reduction. Some plasma actuators feature optimized e…

A laser-microfabricated electrohydrodynamic thruster for centimeter-scale aerial robots

Hari Krishna Hari Prasad, Ravi Sankar Vaddi, Yogesh M Chukewad +3

To date, insect scale robots capable of controlled flight have used flapping wings for generating lift, but this requires a complex and failure-prone mechanism. A simpler alternati…
