Requesting images/info on these rotorcraft

No, the comapy you're thinking of is Beechcraft, or Beech Aircraft Corporation (note different spelling) founded by Walter H. and Olive Ann Beech in 1932. Also note the date of the "Beach helicopter" predates the Beech company by 12 years.

The Loire C.305 was a licence-built variant of the Cierva C.30 by Liore et Olivier, later SNCASE. There were more variants of the same built before the C.305 model, plus the LeO C.34 based on a Kellett autogyro.

Interesting to see the names Pitcairn and Yuriev associated with rotorcraft waaaaay before the projects we know about (autogyros for the former, VTO fighters for the latter).

I do not know about the Weymann CTW.200, but about the CTW.201 (most probably a very similar design) which he submitted to the French Navy. It was tested in February 1933 at Villacoublay but was not proceeded with.

I see you've added a Weyman CTW.210 to your other list. I believe that is a misprint of the CTW.201.

Stingray · Administrator

Not saying you're wrong, but without a source to prove it either way I'm keeping it in the list as a placeholder to further my research.

Yuryev helicopter of 1912

Engine Anzani W-3 27...30 HP 3 cylinder 4 stroke

Main rotor 8 m; 140 rpm

Tail rotor 2.5 m; 450rpm

Mass 203 kg (not sure empty or takeoff)

Estimated thrust 240...260 kg

Wood/Bamboo truss fuselage

Because the engine run not smooth it broke main rotor shaft and they stopped further experiments.

The drawing is 1911 year helicopter with gnome engine(i think it was not built).

Guess who had the idea of the worlds fastest rotorcraft(Eurocopter X3(for now)) in year 1910!!!!!!

Please note, I'm no longer interested in John B. Guest's rotorplane from 1932, as far as rotorcraft research goes, since it was actually a cyclogyro attempting to exploit the Magnus effect via two pairs of rotating cylinders.

Nevermind. I now have a special section for cyclogyros, so feel free to post relevant material there.
