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


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 140 hp Siemens-Halske Sh 14 radial engine that drove a two-bladed wooden propeller.


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.
