An investigation has been made in the Langley low-turbulence pressure tunnel at low subsonic speeds through a range of Reynolds number from approximately 1.0 X 10(exp 6) to 7.6 X 10(exp 6) to study the effects of body indentation in accordance with the transonic area rule on the zero-lift drag of a transonic body in combination with a 45 degree sweptback wing having an aspect ratio of 4, taper ratio of 0.3 and NACA 65A006 airfoil sections.
