Side-by-side 2-seat ultralight airplane
The choice of avionics for Risen mirrors its philosophy: excellence without compromise.
The glass cockpit Dynon combines two 10” touch screens with one 7” central display. Additionally, a 2-axis autopilot and a computer for flap control are standard.
Efficiency and AerodynamicsRisen has been designed using tools and expertise generally found only in large aeronautical industries. Advanced fluid dynamics, in particular, is the secret behind Risen’s outstanding flight characteristics.
Every detail as well as the overall shape of the aircraft were meticulously studied and optimized. The synergy of these optimizations resulted in an aircraft of spectacular efficiency, for example, with a glide ratio of 1:23 and speeds unheard of in any aircraft powered by the Rotax 912 engine. Careful design of all aerodynamic aspects assure reliable and desirable behaviour throughout its exceptionally large flight envelope.
The meticulous attention to aerodynamic details behind Risen’s design is evident also from the choice of propeller: when propellers available on the market were found not to be optimal, SEA’s engineers developed a propeller design of their own which unlocked the full potential of this aircraft. At the low end of Risen’s speed envelope, generously dimensioned flaps give it a very low stall speed.
