Ocala, Florida, June 1, 2004. Hanley Innovations, a leader in aerodynamics conceptual and preliminary design software, announces the availability of WingTail Calculator 2.0 and WingTail Calculator Plus, 2.0.

The Wing Tail Calculator accurately computes lift, drag (vortex and profile) and moment (about the center of gravity) for isolated airfoils, single wings and two-wing systems (or keel-rudder interaction). It can also predict the neutral point (or aerodynamic center) location and the angle of trim.

The WingTail calculator is based on the vortex lattice method (vortex rings) which makes Wing-Tail a powerful and easy-to-use tool for load prediction and longitudinal stability analysis.
