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 flight of the UAV complex in December 70-year. Two years later, the state began a joint trial, which ended successfully in 1976 year. Even before the completion of state tests, 73-m, decided to mass production of drones. Officially, the Soviet Army BP-3 «Flight" was adopted in 1982 year. And after seven years of series production ended. Total EDO issued 950 copies intelligence systems.
UAV Tu-143 presented as an all-metal monoplane with a triangular low-wing small elongation. The front of the fuselage mounted fixed drone destabilizer shape of a triangle. It provides the needed stability margin for the cruise flight modes and delta wing and a 58-degree sweep of the leading edge has a small reverse sweep. The fuselage of circular cross-section becomes oval just in the area of installation turbojet propulsion. Above is an air intake fuselage and tail section is the parachute container. 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 complex BP-3 «Flight" stocked with free riders Tu-143 designed for tactical reconnaissance aircraft at a distance of 60-70 km from ground control points using the radiation board, television and photographic equipment. Thanks to him, provided the detection point and area targets, engineering structures. In addition, the complex is tracking the position of the radiation environment on the flight path in moderate cloudiness. UAVs used quite reserved and can take off and sits 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.
