Aerodynamics and Controls
Designing the geometry of our two wings configuration we use the NASA Vortex
Code to minimize the induced drag of the main wing which is also influenced by
the canard. Some hundred hours were spent until we reached a satisfying
result. An important detail hereby is the vertical staggering of the lifting surfaces.
Beside this we optimized the overall design for ‚state of the art' L/D ratio ~ 47.

A further innovation concerns the yaw
control by electrical driven drag rudders
and the pneumatic actuators for the
glide ratio control during final approach.
Specifically developed soft- and
hardware (fly by light) were introduced
to guarantee the failsave yaw controls.
