ABSTRACT:
A method of forming a composite structure having precision surface openings, such as an air foil through which air can be drawn in for boundary layer control. A metallic face sheet is bonded to a base member that is formed with elongate channels which are to serve as air plenums. A protective metal strip is inserted into each channel, and a high velocity water jet is directed against the face sheet at the area of each channel to form a through slot opening. The protective strip protects the base material from the inpact of the water after it passes through the slot being formed.
