Abstract :
Improvement of unmanned aerial vehicle navigation reliability in rough air and gusts provides by aerodynamic characteristics of Unmanned aerial vehicle. Investigation of leading edge vortex generators effectiveness in subsonic wind tunnels and on RC airplane was presented. Leading edge vortex generators, which form vortex slat can influence on flow separation, therefore increasing critical angle of attack by more than 30 degrees.
