INSTALLATION
------------
1.- Unzip "Fl1852k2.zip" into a temporary folder
2.- Move the folder "FL-185" into the FS2002 Aircraft directory.
3.- Unzip "Gauges.zip" into the FS2002 gauges directory.
The real Flettner FL-185 Heliogyro
----------------------------------
Using the experience gained from the preceding FL-184 autogyro model,
the Flettner FL-185 was the first experimental helicopter to be built by Anton Flettner at the Johannisthal Works in 1936. As it could also be used in autogyro mode, it was called "heliogyro".
This single-seater was equipped with a 140 Hp Siemens-Halske Sh 14 B radial engine (150 Hp according to some sources).
The FL-185 had several improvements over its predecessor: Its rotor was powered, and had full cyclic and collective control. Moreover, it did not have a tailplane/elevator. Two lateral reversible-pitch propellers mounted on outriggers, counteracted rotor torque.
When flown as an autogyro, the rotor was allowed to rotate freely and the lateral propellers gave propulsion.
The radial engine in the nose did not have a propeller, but a cooling fan.
Similarly to the FL-184, only one unit of the FL-185 was built, the D-EFLT, and flown several times in 1937. Anton Flettner was already planning a different twin counter-rotating, intermeshing rotor concept for his next aircraft, the FL-265, which came out two years later after intensive testing.
THE VIRTUAL FL-185
------------------
Built with Abacus Aircraft Factory 99 and animated with Abacus Aircraft Animator (Rotor, props, and rudder).
Construction is based on 3-view drawings, photos and information from the Internet at LuftArchiv.de.
FLIGHT DYNAMICS
---------------
Nicely balanced and fine-tuned helicopter FD by Christoph Ruhtenberg. Importing directly 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.
