Wave drag due to lift for transonic airplanes

摘要

Lift dominated pointed aircraft configurations are considered in the transonic range. These are treated as lifting wings of zero thickness with an aspect ratio of order one. An inner expansion which starts as Jones' theory is matched to a nonlinear outer transonic theory as in Barnwell's earlier work. Expressions for the wave drag due to the equivalent body are derived. Some examples of numerical calculations for different configurations are presented.
