A Study of the Effects of Jets Injected from a Slender Body of Revolution on the Side Forces Acting on it at Large Angles of Attack in Low Speeds,
Abstract
The side forces and moments that appear on slender bodies at high angles of attack can be affected by transition inducing devices installed on the nose of the body. In the present investigation the use of air jets as active devices for affecting these forces is studied. It is found that symmetrical injection of subsonic jets near the nose of the body can reduce the side force and can even change its direction. It is found that for the present test conditions - i.e. subsonic flow at subcritical Reynolds numbers a very small amount of injection is sufficient to affect the induced latteral forces and moments.
