Theoretical Calculations of the Supersonic Pressure Distribution and Wave Drag for a Limited Family of Tapered Sweptback Wings with Symmetrical Parabolic-Arc Sections at Zero Lift
Abstract
The study of the supersonic pressure distribution and wave drag of sweptback wings at zero lift has been extended by means of linearized theory to include the combined effects of plan-form taper and curvature of profile. -Calculations have been made for a specific wing with a supersonic leading edge and these results are applicable to a limited family of plan forms. Comparisons have been made of the pressure distributions and the wave drag calculated by this exact linear solution with the results of an arbitrary simplified approximation based on formulas for untapered plan forms with symmetrical parabolic-arc sections. In addition, a comparison of the wing wave-drag coefficient has been made with the results obtained from formulas for geometrically similar swept-back tapered wings with rhombic sections modified by a profile-correction factor.
