What types of aeronautical machines are described above?
PowerJet PowerJet is a Franco-Russian 50-50 joint venture created in 2004 by aeronautical engine manufacturers Snecma (Safran) and NPO Saturn. The company is in charge of the SaM146 program – the sole powerplant for the Sukhoi Superjet 100 airliner – including design, production, marketing and after-sales support. It delivers a complete propulsion system, comprising engine, nacelle and equipment.
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.
