The Kamov Ka-22 Vintokryl (screw-wing) (Cyrillic:Камов Ка-22 Винтокрыл) (NATO reporting name: "Hoop") was a rotorcraft developed by Kamov for the Soviet Air Force. The experimental rotor-winged transport aircraft combined the capabilities of a helicopter for the vertical take-off and landing with those of a fixed-wing aircraft for the cruise. The Ka-22 carried a large payload, having a hold comparable in size to the An-12. Eight world records for altitude and speed were set by the Ka-22 in its class, none of which have since been broken.
