NOTE OH COMPRESSIBILITY EFFECTS ON DOWNWASH AT THE TAIL AT SUBCRITICAL SPEEDS

摘要

Calculations have been made to show the magnitude of the compressibility effects on the downwash at the tail at subcritical speeds. Experimental results of tests of two airplane models are included to give some verification of the theory.nThe calculations showed that the effects of compressibility on the span load distribution along the wing and on the downwash angle at the tall are small for constant values of the lift coefficient. The experimental results confirmed these calculations.
