The Kamow Ka-22 Wintokryl ( Russian Камов Ка-22 Винтокрыл , Russian for "screw wing ", NATO code name : Hoop , tire) was a very large transport flight helicopter , the Kamow , inspired by the Fairey Rotodyne , on behalf of the Soviet air force constructed.

development

The unusual propulsion concept provided that the rotors were driven for take-off and landing, then the propeller thrust was used for forward flight . The two turbines powered both the propellers and the rotors mounted above in a tandem configuration via adjustable clutches . As with all flight helicopters, the advantages of this construction only come into play in combination with wings and then enable higher flight performance than helicopters . The Ka-22 achieved a significantly higher top speed than comparable pure rotary wing aircraft . It set eight records for rotary wing aircraft - in the areas of payload / altitude and speed (356 km / h) - which have remained unbroken to this day.

The Ka-22 was seen only once at an aviation exhibition in Moscow in 1961. It had the hull of the Antonov An-10 , which theoretically gave it a capacity of 80 to 100 people. The payload was more than 16 tons.

After two accidents, the highly complex development program was discontinued in 1964 and there was no series production at the planned plant No. 84 in Tashkent. The Kamow company, otherwise known for its coaxial helicopters, later worked on other helicopters: the even larger Ka-35 was to use jet engines for propulsion, the W-100 was a design from the 1990s for a fast combat aircraft , also with tandem rotors , but a pusher propeller . However, both designs have not reached the prototype stage.
