THEORETICAL SOLUTIONS AND NUMERICAL RESULTS FOR LOW-ASPECT-RATIO RECTANGULAR JET-FLAP CONTROL SURFACES.
Abstract
The lifting problem of a finite-aspect-ratio, thin, jet-flap control surface of rectangular planform in unbounded, incompressible, subcavitating flow is considered in the improved low-aspect-ratio approximation of H. R. Lawrence. A general method of numerical solution is derived for any regular or singular blowing jet-flap geometry. Numerical solutions are carried out for the following specific configurations: regular blowing from a flat plate at angle of attack; regular blowing over deflected mechanical flaps of ten and twenty percent chord; and singular blowing from a flat plate at zero angle of attack. Tables and curves of the computed lift and pitching-moment coefficients and chordwise load distributions for these configurations are presented over a wide range of the governing parameters. (Author)
