Vultee V-11 и V-12

Прототип штурмовика Vultee V-11 выполнил первый полет в 1935 году, но вскоре разбился. Самолет спроектирован на основе V-1A с новым горизонтальным оперением и фюзеляжем эллиптического сечения. Экипаж из двух человек разместили тандемом в закрытой длинным прозрачным ДальшеMore>>> фонарем кабине.
   Вслед за V-11 вскоре построили прототип V-11G, главным отличием которого являлся мотор SGR-1820-G2 Cyclone мощностью 1000 л.с. (746 кВт). Потенциальным заказчикам предложили и трехместный прототип V-11GB. Китай заказал 30 V-11G, которые принимали участие в боях с японцами.
   СССР закупил один самолет V-11GB с расчетом наладить выпуск самолетов по лицензии под обозначением БШ. Всего построили 31 самолет. Летные данные БШ сильно упали из-за установки советского мотора М-62 мощностью 920 л,с. и брони. Штурмовики переделали в почтовые ПС-43, эти самолеты использовались для перевозки грузов на протяжении всей Великой Отечественной войны.
   Турция заказала 40 самолетов V-11GB, ими в 1937 году вооружили 2-й полк турецких ВВС. Наконец 18 V-11GB и восемь машин в варианте торпедоносца-бомбардировщика с поплавковым шасси закупила Бразилия.
   Под впечатлением экспортных поставок авиационный корпус Армии США закупил для оценочных испытаний семь V-11GB под обозначением YA-19. Затем самолеты доработали под испытания двигателей. На XA-19A испытывался экспериментальный мотор Avco Lycoming O-1230-1 мощностью 1275 л.с., а на XA-19B - Pratt & Whitney R-2800-1 Double Wasp мощностью 1800 л. с.

A MILITARY VULTEE
Attack-Bomber Type: 2,700 Miles at 192 m.p.h. with 1,100 lb, Bomb

   PERHAPS the most universally admired single-engined transport monoplane produced in the United States in recent years is the Vultee V-1A monoplane, a flying trial of which was described in Flight of October 3 this year. The Airplane Development Corporation (a division of the Cord Corporation), whose works are at Glendale, California, and who produced this machine, have now built far the export market (mainly, it is believed, with an eye on the Orient) a single-engined attack-bomber monoplane which might be regarded as a military development of the V-1A.
   The Vultee method of construction was described in detail in Flight of March 23, 1934: for the purposes of this description the new machine will be dealt with from the military standpoint.
   It is classed by the manufacturers as an attack-bomber type, which means that it is suited to "contract patrol," or ground strafing work, in addition to long-range bombing. Standard U.S. Army load factors for attack machines have been used in the design of the structure. Basically the machine is an all-metal low-wing cantilever monoplane of metal-stressed skin construction, fitted with a Wright Cyclone radial engine, an inwardly retracting undercarriage, flaps and C.P. airscrew. The empennage of the new military machine is of a type favoured in Germany, with the tailplane and elevator placed high on the fuselage and forward of the rudder.
   One striking feature of the design is the long cockpit enclosure for the pilot and observer. The pilot, who releases the bombs, is seated just aft of the leading edge of the wing, and the observer, who also has a set of controls, is roughly over the trailing edge. Protection for the pilot in the event of nosing-over has been provided by a tripod immediately behind the pilot's head, capable of sustaining six times the gross weight of the machine.
   Even as a bomber the machine carries four 0.30 in. calibre Browning-type MG-40 machine guns installed within the inboard leading-edge section of the outer wing panels, two guns being located in each wing. Stainless steel ammunition boxes of 600 rounds capacity and ejection chutes are provided for each gun. The guns are manually charged and electrically fired by a pistol trigger grip on the control column. Another 0.30 in. calibre Browning gun is provided for the observer.
   Bombs are carried both internally and externally. Racks are provided in the fuselage and wing for twenty 30lb. bombs the internal racks being sufficiently deep to permit the carriage of either chemical or fragmentation types. Stainless steel guide chutes are provided to position each bomb separately, and to guide it until it has left the machine. Doors are located at the bottom of these chutes, which are inclined 10 degrees aft of vertical.
   Ten 120 lb. bombs are carried under the centre wing panel in two groups of five, one behind the other, the forward group being located so that the tails of the projectiles clear the internal bombs. The centre shackle provided for this group is mounted forward of the other four, so that when a 1.100 lb. is carried its tail has a ground clearance of not less than 10 in. On the outer shackles 285 lb. or 625 lb. bombs may be carried.
   Either a Wright Cyclone SR-1820-F52 (820 h.p. for take-off and 775 h.p. at 5,800ft.) or a Cyclone F-53 (750 h.p. at 11,000ft.) is fitted. The airscrew is a Hamilton Standard C.P. type with a 10 deg. pitch range.

SOME NEW AMERICANS
Contrasted Types, but all Fast: The Vultee V-11: Consolidated P-30: Grumman F2F-1: Rasmussen IIa Racer

   VULTEE F-11. - A fairly comprehensive description of the new Vultee attack-bomber monoplane - now, incidentally, known as the V-11 - was published in Flight of October 31, 1935. Since that date the manufacturers have been subjecting the machine to thorough tests and have lately issued a new set of performance figures. The maximum speed is given as 230 m.p.h. with the Wright Cyclone SR-1820-F53 engine, and the range, as a bomber carrying full fuel load, is 2,200 miles, which is 500 miles less than the original figure - presumably an estimated one.
   The V-11, some details of which are revealed on the previous page, is being offered for export, and, so far as is known, has not been adopted by the U.S. Government. It has, nevertheless, a performance superior to that of any comparable machine in use in the U.S. Army Air Corps.
