Summary

This app calculates the lift-curve slope and aerodynamic centre position for wings with straight  leading- and trailing-edges and streamwise tips in supersonic flow, using the method of ESDU 70012.

The method was derived from lifting-surface theory and is applicable for $\beta A$ up to 12,  $A \thinspace tan \thinspace \Lambda_{1/2}$ up to 6 and taper ratio ($\lambda$) from 0 to 1, where:

$A$	is aspect ratio,
$\beta$	is $(M^2 - 1)^{1/2}$
$M$	is Mach number,
$\Lambda_{1/2}$	is the mid-chord sweep.

Comparisons with test data indicate that the lift-curve slope is predicted to within about 15% and the aerodynamic centre position is predicted to within about 0.05 of the aerodynamic mean chord.

The program includes extensions to the method of ESDU 70012 to cover wings with higher values of aspect ratio, $\beta A > 12$ and a limited amount of forward mid-chord sweep.

Note: The user should consult ESDU 70012 for full specification and discussion of the wing configurations and flow conditions covered by the data used in the derivation of the method, and additional advice on the applicability.

(See ESDU 70011 and its accompanying Toolbox app for the subsonic flow case.)
