NACA-TN-4200
Effectiveness of boundary-layer control, obtained by blowing over a plain rear flap in combination with a forward slotted flap, in deflecting a slipstream downward for vertical take-off
Year: 1958
Abstract: The wing employed in this investigation had a 67-percent-chord slotted flap in combination with a 33-percent-chord plain rear flap equipped with a full-span blowing nozzle. The tests were conducted in a static-thrust facility at the Langley Aeronautical Laboratory. The investigation indicated that the plain rear flap alone with a low momentum coefficient for boundary-layer control provided larger turning angles than the combined slotted and plain flaps without boundary-layer control.
