What types of aeronautical machines are described above?
Sukhoi Superjet 100 The Sukhoi Superjet 100 (Russian: Сухой Суперджет 100 ) is a modern fly-by-wire twin-engine regional jet with 8 (VIP) to 108 (all economy) passenger seats. With development initiated in 2000, the airliner was designed and spearheaded by Sukhoi, a division of the Russian civil aerospace company (UAC), in co-operation with several foreign partners. Its maiden flight was conducted on 19 May 2008. On 21 April 2011, the Superjet 100 undertook its first commercial passenger flight, on the Armavia route from Yerevan to Moscow.
Dayton-Wright Racer The Dayton-Wright RB-1 (Rinehart-Bauman model one), also known simply as the Dayton-Wright Racer was a racing aircraft developed in the United States to participate in the 1920 Gordon Bennett Cup air race. Advanced for its day, the aircraft was a high-wing monoplane with a monocoque fuselage and cantilever wing (built of solid balsa wood covered in plywood and linen that incorporated a Grant designed mechanism to vary its camber in flight by moving the leading edge and trailing edge. The aircraft also featured a retractable undercarriage operated by a hand-crank making it one of the first instances of undercarriage retraction for aerodynamic benefit alone. The propeller shaft was mounted through a large oval radiator, the pilot had no forward view, but was provided with flexible celluloid side windows. Cockpit access was through a hatch in the top of the fuselage. A prototype was built using non-retractable gear and strut-braced wings. A shorter tapered "racing wing" was installed afterward with leading and trailing edge flaps interconnected with landing gear deployment. The mechanisms and hinges for the wing flaps were exposed across the top of the solid wing. The racing wing produced directional instability requiring small tail fins to be added.
