An apparatus for use with channel winged aircraft to seal the airfoil surface of the channel between the trailing edge thereof and the propeller tip, by discharging jets of water rearwardly from the leading edge of the airfoil surface of the channel to form a film of water on said surface. The film of water seals the space between the propeller tip traveling at or near the speed of sound and the channel surface where very low pressure is created just ahead of the propeller tip, so as to prevent spillback of air through this space.
