The real Flettner FL-265 Helicopter
-----------------------------------
In 1937, using the experience gained from the preceding FL-184 autogyro and FL-185 Heliogyro models, Flettner began work on a much more refined helicopter, the "Fl-265", at the Johannisthal Works. This aircraft had a single engine driving two contrarotating rotors through a gearbox.
This single seater´s twin-bladed rotors were on shafts on either side of the gearbox, driven by a 150 Hp Siemens Bramo Sh 14 B radial engine in the nose, with the gear arrangement keeping the two rotors at a right angle to each other, and the shafts turned outward slightly so the rotors intermeshed without colliding. This is known as an "eggbeater" configuration, and is still used in some modern helicopters.
The radial engine did not have a propeller, but a cooling fan. Six units were built.
The German Navy began to provide funding to Flettner in 1938, and the Fl-265 made its first flight in May 1939. The Fl-265 led to a bigger and refined production version, the "Fl-282 Kolibri (Hummingbird)", with a 160 horsepower radial engine.
THE VIRTUAL FL-265
------------------
Built with Abacus Aircraft Factory 99 and animated with Abacus Aircraft Animator (Rotors, fan and rudder).
Construction is based on 3-view drawings, photos and information from the Internet at LuftArchiv.de.
FLIGHT DYNAMICS
---------------
Very well-balanced and fine-tuned helicopter FD by Christoph Ruhtenberg. Direct importing into FS2002 seems not to have done any damage.
INSTRUMENT PANEL
----------------
Simple custom panel with old fashioned instruments. The scarce gauges are some standard FS gauges and some antique third-party instruments that fit the era quite nicely, but whose origin I have unfortunately lost track of, and whose authors have done a great job creating them.
SOUNDS
------
Default Bell Helicopter 206-B sounds. However, the sounds from the Sikorsky VS300 experimental helicopter VS300.ZIP are recommended.
