DACPEI is a WYSIWUG Software for Conceptual design of Light Fixed Wing aircraft. It is specifically designed to be intuitive and easy to use by engineering students (not necessary aerospace/aeronautics).
DACPEI is divided in 9 modules, for analyzing mission profile, Aircraft performance, propulsion and layout design, as well as sketch component for developing aircraft drawings. DACPEI enable users to export their design to the FlightGear flight simulator software, enabling the designer to "test-drive" their designs while they are on the drawing board. Designers will get an immediate feel for the performance and handling qualities of their designs in less than 7 minutes.
Easy to use and works.
