The VVA-14 first flight was held on September 4, 1972. It was tested by pilot Yu. Kupriyanov and navigator L. Kusnetsov. In 1975 the test program was completed, the plane performed 107 flights with a total flight time 103 hours.<\/span><\/p>\nThe plane's all round\u00a0metal airframe comprises a fuselage, middle portions of central wing, two side sections with floats, torsion-box central wing, two removable wing portions, tail, cruising engines' nacelles over fuselage.<\/p>\n
The side sections are intended to fix horizontal and vertical tail, floats and main units of tricycle wheeled landing gear. The removable wing portions have slats, slotted flaps, and ailerons. The tail is provided with elevators and rudders.<\/p>\n
Above the evolution speed, the plane is controlled with aerodynamic control surfaces. During vertical takeoff and landing as well as during transient process, the plane is controlled with jet vanes. The plane control system includes the SAU-M automatic control system.<\/p>\n
Design, test and production of a LG pneumatic retractable floats was a complicated problem. It was solved only two years after the first plane's flight.<\/p>\n
The powerplant comprises two cruising D-30M bypass turbojet engines designed by P. Solovyov and 12 lift RD-36-35PR turbofan engines designed by P.Kolesov as well as TA-6A turbo generator - an auxiliary airborne unit. There are fuel (15,500 kg of fuel capacity), deicing, and fire extinguishing systems.<\/p>\n
The \"Burevestnik\" search-and-aim system was especially developed to let the crew detect, track, and destroy hostile submarines with high accuracy. The \"Bor-1\" airborne search magnitometer, radio sonobuoys and weapons automatic release mechanism, flight-and-navigation system operate jointly with this search-and-aim system. Crew members (a pilot, navigator and operator) are accommodated in ejection cockpit capsule that provide the possibility to save the crew in all flight attitudes and to stay for long time in it after landing to the ground or water. The third copy of the plane is supposed to use for the ejection cockpit capsule testing.<\/p>\nAdditional Reading \u2013\n
