Aerotechnik WG.22

 

aero-wg22


Following successful testing of the single-seat WGM 21 prototypes, Aerotochnik developed a side-by-side two-seat version, the 1975 WGM 22, with an extensively-glazed and fully-enclosed cabin.

The configuration of the WGM 21 and WGM 22 differs essentially from other and more familiar forms of helicopter in having four two-blade rotors, each mounted at the extremity of one of a pair of diametrically-opposed rotor support arms on top of the main rotor column. This configuration allows the entire output of the engine to be transmitted directly to the main rotors, and eliminates the need for tail control surfaces or a tail rotor. The support arms can be folded enabling the helicopter to be stored in a small area.

It was estimated that the WGM 22, shown in mockup form in the accompanying photograph, should have a max speed of about 200km/h and a range of 800km.
