An investigation was conducted on the effect of setback, combined with elevated gas temperatures, on Coanda attachment to a curved plate. The tests used a rectangular convergent nozzle. Chamber temperatures ranged from ambient to 1100 F. Turning efficiency and surface pressure distribution were analyzed. Air flow patterns over a flap on a 16th scale propulsive wing model were analyzed. Nonuniform air flow is discussed with regard to flow separation. Author
