We were tasked with the design and construction of a single-seater subsonic jet trainer. In addition to designing the CFRP structure, a further focal point was the aerodynamic design and the determination of expected flight performance. To this end, the computational software Tornado was employed. To verify the calculations and to further improve flight characteristics, SFL GmbH designed and built a test vehicle in a scale of 1 to 3 and installed its own measuring equipment to collect flight data.
