Investigation consisted of force tests of model and wing alone for angle of attack range from -- 8 to 12° and for momentum coefficients up to about 3.0; results indicated that double slotted flap arrangement was more efficient in terms of lift and drag than external flow single slotted flap arrangements previously tested.
