Tupolev BP-3 FLIGHT

The complex is air tactical reconnaissance VR-3 «Flight» UAV Tu-143 reusable designed in 60-ies and was completed in the year 168 engineers OKB Tupolev. All unmanned projects including "Flight" was engaged directly by GM chief designer Gofbauer. The project was developed in conjunction with a complex of "Swift" and embodies all the experience of previous work.

The first UAV flight of the complex took place in December 70. Two years later, state joint trials began, which ended in success in 1976. Long before the completion of state tests, in 73, a decision was made on the serial production of the drone. Officially, the VR-3 "Reis" was adopted by the Soviet Army in 1982. And after seven years, serial production ended. For all the time, the OKB produced 950 copies of reconnaissance systems.

The Tu-143 is represented as an all-metal monoplane with a triangular low-lying wing of a small elongation. In front of the fuselage of the drone is fixed immovable destabilizer in a form resembling a triangle. It provides, you need a margin of stability for flight flight regimes, and a triangular wing with an 58 and degree sweep along the leading edge has a small backward sweep. The fuselage of the round section goes into the oval just in the area of ​​installation of the marching turbojet engine. An air intake is located above the fuselage, and a parachute container is in the tail part. Plumage (sweep 400) Is equipped with a small forkil keel and rudder. The small size of the UAV, the location of its air intake and the use of the right materials contributed to a decrease in ESR.

Designers have decided that as intelligence equipment best suited panoramic aerial camera on the type PA-1 120-meter with film, television equipment "Chibis-B" (I-429B) and equipment for radiation reconnaissance "Sigma-P." All data other than pictures can be transmitted over the air at the NEC.

Absu-143 (automatic on-board system) is used to operate the machine in time flight software and the implementation of planting, as well as capacity for intelligence equipment. Besides Absu-143 controls the autopilot AP-143, calculator In-143, Doppler angle and speed of the demolition of Diss-7, the height of the input unit BVV-1 and altimeter low altitude A-032.

The main purpose of the VR-3 complex "Flight" with the manned Tu-143 free rider is designed for tactical air reconnaissance at a distance of 60-70 km from the ground control station using onboard radiation, television and photographic equipment. Thanks to it, it is possible to detect point and area targets, engineering structures. In addition, the complex monitors the position of the radiation situation at the flight rate under conditions of medium cloudiness. The UAV is quite secretive and capable of taking off and landing on unprepared runways.

Also, with the additional conditions the modernization of BP-3 «Flight" can increase its own depth of penetration into enemy territory to 80 km wide band (10 altitude) with staffing UAV photographic and television means intelligence. To prepare for the launch complex drone needed 15 minutes to restart - 4 hours. Nowadays complex UAV Tu-143 is in service with Russia and Ukraine.
