Rhein-Flugzeugbau RF-1
The Rhine flight RF-1 was a six -seater touring and commuter aircraft manufacturer Rhein -Flugzeugbau. As special features are the STOL performance, the drive by two engines, to name a jointly drive a ducted propeller. When constructed by Hanno Fischer machine, the continuation of the line of the previously designed RW -3 is clearly seen.
A prototype was finished, but flew only once, because the flight characteristics were not considered sufficient. The construction of the second prototype was then terminated.
Construction
The RF-1 was a twin-engined cantilever monoplane. The three-piece, constructed as a welded steel tube frame wings had a central portion that had a semi-annular wing root. The middle part was covered with a shaping plastic sandwich paneling.
The outer wing parts were carried out in a zweiholmigen all-metal construction. Between all-metal ailerons and the propeller ring is slotted flaps were also in all-metal construction. The front part of the fuselage to the wing leading edge was designed as an all-metal box-section design. The tail part was a welded steel pipe backbone which was cased with forming plastic sandwich panels.
The RF - 1 had a cantilevered normal tail with a slightly swept fin. The tricycle landing gear was electrically retractable, with the main wheels were retracted laterally into the ring - fuselage transition and the nose wheel forward under the fuselage nose.
