A wind-tunnel investigation was made to determine the effects of jet-outlet cut-off angle on the directional and spreading characteristics of an unheated, subsonic air jet, and on the pitching moment of the body from which the jet issued. The outlet was incorporated in the tail of an axially symmetric body and was cut at angles of 0, 30, 60, and 75 degrees relative to a plane normal to the outlet axis.
