Kuibychev Aviation Institute Strekoza
The Strekoza (Three-axis) was a single-seat single-engined high-wing mono-plane with three-axis control circa 1983. Constant chord wing; conventional tail. Pitch control by elevator on tail; yaw control by fin-mounted rudder; roll control by full-span ailerons. Engine mounted at wing height driving tractor propeller.
The Strekoza is a com-pletely original design from the students at the polytechnic of Kuibychev and in concept of a mini-aeroplane. Using a conventional tail supported by a metal framework, the Strekoza carries slotted ailerons along the entire trailing edge of its constant-chord high wing. The engine, an air-cooled Wichr-25 developing 25 hp, is placed in a nacelle on the leading edge of the wing, connected to a two-blade 43 inch (1.10 m) propeller.
