Abstract
Viskoznost fluida očituje se u vremenu potrebnom da se fluid izlije iz jedne posude u drugu. Zrak koji pri velikim brzinama opstrujava oko predmeta pokazuje svojstva viskoznosti. Granični sloj tanki je dio struje fluida uz neko tijelo u kojem su moguća dva režima strujanja: turbulentno i laminarno. Plazma aktuatori su uređaji koji aktualizacijom plazme, tj. negativnim nabijanjem zraka, mogu utjecati na strujanje fluida unutar graničnog sloja što za posljedicu ima djelovanje na fundamentalne sile prisutne kod strujanja fluida oko aeroprofila. Dielektrična su svojstva različita za pojedine kompozitne materijale korištene u svrhu zadržavanja naboja. Plazma aktuatori imaju široku primjenu u aerodinamici čija se zasluga temelji na brojnim prednostima električnih sklopova bez pomičnih djelova u odnosu na mehaničke.

Parallel abstract (English)
Viscosity of fluids is a measurement that represents the time necesary for one fluid to be poured from one container into another. Air flowing around an object at high velocities displays the characteristics of viscosity. Boundary layer is a narrow layer of flow right above the surface of the body in which there are two regimes of flow possible: laminar and turbulent. Plasma actuators are devices that by ignition of plasma (negative charged air molecules) affect the flow inside the boundary layer which in turn has an effect on the fundamental forces that appear in the presence of mentioned flow. Dielectric properties differ in compozite materials used for retaining charge. Plasma actuators have a wide-spread usage in aerodinamics which is due to their many advantages of fully electric systems without any moving parts compared to mechanical ones.
