Welcome

This is the webpage for the softwareTornado, a Vortex Lattice method implemented in MATLAB.

The new version, Tornado 136.5, is available in the downloads section.

Tornado is a Vortex Lattice Method for linear aerodynamic wing design applications in conceptual aircraft design or in aeronautical education. By modelling all lifting surfaces as thin plates, Tornado can solve for most aerodynamic derivatives for a wide range of aircraft geometries. With a very high computational speed, Tornado gives the user an immediate feedback on design changes, making quantitative knowledge available earlier in the design process.

The code is implemented in  MATLAB and is being used at many universities and corporations around the world. It is still in a development phase with new functionality added. The code can either be run with a text based interface or in batch mode.
