Analysis of the aerodynamic characteristics

1. At , that corresponds to or (or simultaneously) we receive . That means, the result corresponds to the extreme low-aspect-ratio wing in incompressible and subsonic gas flows. If the wing leading edge becomes sound (), then , i.e. we receive the characteristic of the airfoil of infinite aspect ratio wing in supersonic gas flow.

2. In case of sound and supersonic edges () the non-linear additive to a lift coefficient is equal to zero, i.e. .

3. If , then and at a polar pull-off coefficient , i.e. wing. induced drag ; so as for subsonic flow about high-aspect-ratio wing. It is visible that the sucking force reduces induced drag twice in comparison with that case, if it is not taking into account.

4. Ratios and are also functions of reduced aspect ratio and airfoil plan form (for ).
