Helicopter drag reduction by vortex generators
Aerospace Science and Technology, 2015 Abstract The performance of vortex generators in reducing the helicopter drag was investigated by computational fluid dynamics and wind tunnel tests. Numerical simulations were carried out to define the layout and the position of vortex generators to be tested on a heavy-class helicopter fuselage model. A comprehensive experimental campaign including
