Aircraft Design

The field of investigation Aircraft Design is dedicated to the design and construction of manned and unmanned aerial systems in addition to the classic preliminary aircraft design.


Manned Aircraft Projects

This topic deals with the development, construction, and testing of trendsetting light plane projects. The focus lies on the combination of eco-efficient concepts with alternative propulsion technologies. The solar aircraft ‘icaré’ and the battery powered aircraft ‘e-Genius’ are used by the Institute of Aircraft Design (IFB) for the practical testing of both alternative propulsion and energy storage technologies.

Unmanned Aerial Systems (UAS)

The research group ‘UAS’ conducts research on the design and construction of fixed-wing and helicopter UAVs, development of avionics, system integration and professional flight test planning and execution. The biggest UAVs realized until today are ‘VELA2’, ‘NACRE’ and ‘AMPAIR’.

General / Conceptual Aircraft Design
The aim is the improvement of the statistical preliminary draft tools and the development of new design approaches.
