and autonomy into aircraft conceptual design. While it was our desire to rewrite the books on aircraft design, it was clear we had more work to do on the individual attributes of the enabling technology. We invested in the autonomy of future aircraft with sights set on pilotless aircraft. To that end, we built an unmanned twin- engine tail sitter vehicle that takes off vertically and transitions to fixed-wing flight. The aircraft’s controls were developed via iterative parameter identification; the vehicle essentially learned to fly. A step to achieving full autonomy is simplified vehicle operation (SVO). For SVO, we relied on Flight Level Engineering, a member of the Embry-Riddle Research Park. Flight Level has a strong track record of research on simplified manned aircraft controls using a variable stability airplane that can be reconfigured to mimic the handling qualities of any airplane with operator’s imposed control law. Read more about this area of research on page 21.
