FIELD: aircraft engineering. ^ SUBSTANCE: gyroplane comprises aircraft airframe, rotor arranged on airframe with its blade rigidly fixed with rotor hub and aircraft internal combustion engine. Gyroplane airframe accommodates a pair of high-speed rotors comprising set of blades fitted at sweepback angle ½ with respect to blade section peripheral speed vector ½, where ½ is the angle between blade front edge and plane perpendicular to vector ½. Ends of adjacent swept-back blades are linked up and furnished with jet nozzles. Gyroplane additionally incorporates compressor coupled with aircraft internal combustion engine. ^ EFFECT: increased horizontal flight speed, simpler system of rotor start prior to take-off and easier control in take-off and landing. ^ 2 dwg
