Tupolev VR-2 Swift

BP-2 «Swift» - a complex of Soviet tactical reconnaissance UAV developed reusable specialists Tupolev. It was created as a result of development, extensive testing and refinement of the intelligence complex Tu-123 (DBR-1). A significant role in the creation of "Swift» played a construction DBR-2 (Tu-139), which turned out to design a fully rescues the UAV system.

Bp-2 was the latest in a series of complex, as the results have been very progressive. The continuation of the complex "Swift" was BP-3 «Flight" and BP-3D "Reis-D".

Work on the complexes "Swift" and "Flight" in the OKB conducted almost simultaneously. Much of the technical solutions for both development including layout elements were identical. The main difference is in the range, which directly affects the method of application and tasks. Unmanned complex tactical and operational intelligence BP-2 «Swift» intelligence operations carried out at a distance from the start point of a few hundred kilometers, while the BP-3 «Flight" - about 20-30 km.

Initially, "Swift» planned UAV design dual-mode type. According to the preliminary opinion of the Engineer UAV complex Tu-141 will fly at low supersonic or transonic speed for dual breakthrough of enemy air defenses. That is to fly into enemy territory with the condition of returning back to the landing site.

Following the route reconnaissance drone aircraft must undergo at subsonic cruise. A scout will sit ski for manufactured before planting (for airplane). The same concept offering and representatives of military forces. Preliminary calculations have been carried out and evaluation, which showed that in order to achieve this goal is necessary to increase the weight of an avalanche scout. A to exit briefly at transonic regime would require to optimize the aerodynamic characteristics of the aircraft, in particular regarding its powerplant. One would have to be removed from the layout of a simple single-mode air intake set with greater traction motor (with afterburner). And this will inevitably lead to an increase in used fuel and, naturally, to the starting weight. Thus, in order to meet the requirements of the military and increase the stability of the complex to protect against air defense took hold radical changes and significantly complicate the entire structure of the UAV. And this is directly proportional to the decrease would affect reliability and increase cost.

Based on the research and as a result of a long debate, the designers decided that the best option - to abandon the regime and a supersonic speed limit threshold to 1000 km / h. In addition, the idea of ​​landing on a ski replaced the standard version with a parachute. All new, but small finishing gradually begun to change the project to a large-scale copy of the increased tactical unmanned reconnaissance aircraft Tu-143.

The end result of "Strizh" began to resemble its smaller copy - complex "Flight". The difference was expanded intelligence and on-board equipment, the size and number of UAVs and ground complex of means of support and combat service work. And the use of complex Tu-141 was just an enlarged copy of the Tu-143.

Complex BP-2 «Swift" was developed under the leadership of GM Gofbauer, who was the head and leader of unmanned vehicles to the EDO 90-ies.

The first prototype of the complex flew in December 74-year. Its equipped with advanced engine KR-17A. Though the complex itself is not particularly promoted, his plane was very popular among the military. Series production began in 1979, the plant № 135 (current Kharkov Aviation Plant) and ended later 10 years. Total units created 152 serial Tu-141. In the first trial batch used motor R9A-300.
