Shenyang BA-5I CK-1

Speaking of unmanned vehicles in China, it should be noted that a large number of machines are supplied with the Soviet Union. So, at the end of 50-ies of the last century in China gave a whole batch of target model of La-17, which was created by the legendary designer at OKB Lavochkin still 1953 year. Due to the majority of their operation fails, which is why it was decided to create its own unmanned machines.

The creation of a new machine is loud, since the design was copied from the Soviet apparatus La-17. Designers of China began the creation of an aircraft in 1968 year. The first created party consisted of 9 devices, which worked out flight tests. Finally, the finalization of the car ended in 1976 year. The unmanned vehicle manufactured by the Chinese was named Ba-5I, but the most famous export name of the car is SK-1. Since 1977, this unmanned target has become the arsenal of the Chinese army. Despite the fact that UAV was created on the basis of the model of the USSR, he had other flight profiles.

The machine had 8,4 7,5 meters in length and meters wide wings. As for the masses, it is intact and charging indicator reached 3,3 tons. The powerful engine with a thrust of 2600 kgs allow to produce high-quality take-off and flying at a speed of 900 km / h. At the same time the range of application of the device is 600 kilometers, and the car could climb tall 18 kilometers.

The design of the SK-1 is presented in a normal aerodynamics scheme, with simplified rectangular wings. The interchangeability of horizontal and vertical plumage became a special feature. As for the power plant, it was represented by the TRD engine of the WP6 model. The engine was attached to the gondola outside the fuselage of the aircraft. The UAV had an autopilot system, which was developed by the designers of China. The launch of the device was carried out with the help of a ground installation, as well as additional powder charges for acceleration during take-off. The flight process could be carried out manually from a ground control station or a predefined program. Upon completion of the mission, the UAV landed using a parachute system.

The tests showed that the car has excellent performance. That's why the development of the project did not stop, due to which there were modifications to perform more highly specialized tasks. The UAV-1A was equipped with equipment for radiological reconnaissance and study of nuclear explosions. For the first time this model was used in nuclear tests in 1977 year when a bomb was bombed in the atmosphere. The second modification with the designation SK-1V was ready in May 82-year, its main task was to simulate air targets at low altitudes. Also in 1983, a new modification of the SK-1S target was made, which could simulate modern aircraft with high maneuverability at that time. This machine was used for the development of antiaircraft systems. The last modification was the UAV under the designation SK-1E, which was intended for development of flights on low flights.
