Aircraft design /technology integration and assessment represents main research field at ILR. In ILR lecture Fixed Wing Aircraft I: students will work on old aircraft concepts to build up "system thinking". In ILR lecture Fixed Wing Aircraft II: students will execute a full design cycle to build up "system knowledge". In ILR lecture Computer‐Aided Aircraft Design: students get familiarized with current conceptual aircraft design tool. C++ tool templates enable to motivate students to do tool development (which otherwise would refuse).
