The Flettner 184 was a German night reconnaissance and anti-submarine autogyro developed during the 1930s.

Design

The Fl 184 was a two-seat autogyro with an enclosed cabin. The Fl 184 rotors had a length of 12 m and a cyclic pitch control system. The aircraft's power was supplied by a 160 PS (160 hp; 120 kW) Siemens-Halske Sh 14A radial engine that drove a two-bladed wooden propeller.

Operational history

The sole Fl 184, given the registration D-EDVE, was scheduled to be tested for night reconnaissance in late 1936. However, before these tests could take place, it caught fire whilst in flight and crashed.

After the crash the entire program was cancelled and no more aircraft were manufactured.
