Verville Sportsman / PT-10

Verville. Самолеты

Альфред Фервиль был конструктором в инженерном отделе Воздушной службы Армии США (USAAS) и разработчиком гоночных самолетов Verville-Packard и Verville-Sperry.
   В конце 1920-х годов он основал в Детройте, Мичиган, фирму "Verville Aircraft Company". Ее первым самолетом стал Verville Air Coach 104-C - подкосный высокоплан с закрытой четырехместной кабиной и радиальным ПД Wright J-6 мощностью 225 л. с. (168 кВт). Было построено шесть или семь самолетов, но сертифицированный полугодом позже Air Coach 104-P оказался менее удачным - продали всего одну или две машины. Видимо, причиной была его силовая установка - дизель Packard DR-980; многие потенциальные покупатели просто опасались связываться с новинкой.
   Последним самолетом "Verville" был Sportsman AT, двухместный биплан с расположенными тандемно кабинами и 165-сильным (123 кВт) радиальным ПД Continental A70. Всего построили около десятка таких машин.
   Фервиль построил для авиакорпуса Армии США (USAAC) четыре близких по конструкции, но усиленных самолета, оснащенных 165-сильным (123 кВт) ПД Wright R-540, проходивших испытания под обозначением YPT-10. Позднее USAAC оснащали их различными силовыми установками, что привело к появлению обозначений YPT-10A и YPT-10B (с ПД Continental R-545 и Wright GR-540, соответственно, оба мощностью 165 л. с./123 кВт), YPT-10C (180 л.с./134 кВт, мотор Lycoming R-680) и YPT-10D (170 л.с./127 кВт, Kinner R-720).

THE VERVILLE TRAINER
A New American Training Machine

   THE Verville Aircraft Company of Detroit, Michigan, has recently announced the Verville Sport Trainer and the Verville Service Trainer, built under Approved Type Certificate No. 323. Alfred V. Verville spent seven years as final design engineer for the Army Air Service. His experience there designing aircraft to Air Service specifications (notably the Verville-Chasse, Verville Packard Racer, Verville Sperry Racer, and the PW-1) reflects itself in his latest creation.
   The two models in question are identical except for the equipment, the former being a luxuriously equipped Sport ship, and the latter carrying only customary training accessories. They are designed strictly in accordance with all specifications and load factors of Army training planes, and are as a result extremely rugged.
   The Verville Trainers are two-place, open, land biplanes with provision made to convert them into seaplanes. The wing spread is 31 ft., height overall 8 ft. 9 in., and length 24 ft. 3 in. A solid upper panel is used with four degrees dihedral in the lower panels. Sufficient stagger is used to provide unobstructed egress from the forward cockpit. Both cockpits are exceptionally roomy and are provided with comfortable parachute type seats.
   By means of an unique design the extreme rear of the fuselage is built with a rigidity which prevents any possibility of nutter, weave, or distortion of the control surfaces.
   Welded, chrome molybdenum steel tubing is used throughout the fuselage and tail surfaces. The wings are built up of solid wood spars and fabricated wood ribs. Ailerons are riveted duralumin.
   Flightex fabric treated with acetate dope and special lacquer is used to cover the entire structure. Convenient hinged aluminium inspection doors are provided at all desirable locations to facilitate servicing of wearing parts.
   An ingenious brake control system is installed providing simple, convenient, and effective operation of brakes from either cockpit, separately or simultaneously.
   The ship is powered with the Continental A-70 165 h.p. motor and has for standard equipment as a Sport ship: Standard steel propeller, Heywood air starter, balloon wheels, dual A.P.C. brakes, oildraulic shock absorbers, full caster tail wheel, dual stick control, parachute seats, head rest, two three-piece safety-glass windshields, gasoline gauge, tool compartment and kit air speed indicator, two tachometers, compass, two altimeters, two oil pressure gauges, two oil temperature gauges, navigation lights, dry battery, fire extinguisher, first-aid kit, dual throttles, dual switches, dual stabiliser adjustment, baggage compartment.
   When delivered as a Service Trainer no starter is installed and sundry other equipment, not desirable for student work, is omitted.
