SNCASE SE-3101
The SNCASE SE-3101 (Sud-Est SE-3101) was an early, experimental French helicopter with twin tail rotors. Only one was built.
The SE-3101 is an early, experimental helicopter, developed by the German aviation pioneer Henrich Focke. The helicopter is probably the first French example to have tail anti-torque rotors. It has a single main rotor and a similar layout to many modern helicopters, apart from its use of a double tail rotor. These are mounted with their axes at 45° to the horizontal and with 90° between them, the drive shafts faired within a V-tail-like rear structure.
