2. The WZ-5 Pilotless Aircraft
Developed by the Beijing Institute of Aeronautics and Astronautics, the WZ-5 is a high-altitude reconnaissance drone. It specializes in the photographic reconnaissance of large areas such as battlefields. Research for the aircraft began in August 1970 after being assigned by OIND to the Beijing Institute of Aeronautics and Astronautics.
For its powerplant, the WZ-5 pilotless aircraft was equipped with a WP11 engine that produced a maximum thrust of 8.3 kn. The WZ-5 was guided by an onboard control system with autopilot, a Doppler radar, and a long- range gyroscopic compass.
In order to be deployed, the WZ-5 had to be carried and released by another aircraft, such as a Tu-4. The aircraft was remote controlled by a ground control station The pilotless aircraft had to be carried and then released by a carrier aircraft, monitored and remotely controlled by a ground control station. After performing its mission the WZ-5 is equipped with a parachute for recovery. The automatic control system of the WZ-5 was jointly developed by the Beijing Institute of Aeronautics and Astronautics and the Lanzhou Flight Control Instrument Factory.
In November 1972, the WZ‑5 pilotless aircraft made its first successful deployment from a Tu-4 and was certified after a test flight in May 1978. In the test, the WZ-5 had a flight time of 3 hours, 14 minutes and had a range of 2,380 km. The WZ-5 was certified for delivery to the Chinese military in December 1980.
For the purpose of surveying small areas, the Northwest Polytechnic University developed a smaller remote controlled aircraft designated as the D4.
