Легкий пассажирский самолет

Focke-Wulf F 19 Ente

Хайнрих Фокке направил в середине 1920-х годов "Deutsche Versuchsanstalt fur Luftfahrt" (DVL) предложение о постройке необычного пассажирского самолета, спроектированного по схеме "утка". Постройке прототипа предшествовали продувки моделей в аэродинамической трубе в Гёттингене.
   F 19 Ente представлял собой высокоплан со свободнонесущим крылом, каркас фюзеляжа выполнен из стальных труб, обтянутых полотном. В фюзеляже размещены открытая кабина для двух летчиков и закрытая кабина для двух пассажиров. Вертикальное оперение установлено традиционно - в хвостовой части фюзеляжа, но горизонтальное оперение вынесено вперед и смонтировано на стойках над носовой частью фюзеляжа. Размах горизонтального оперения 5,20 м. Силовая установка включает два мотора Siemens Sh.11 мощностью по 75 л.с. Первый полет на F 19 Ente выполнил Георг Вульф 2 сентября 1927 года. Вульф погиб через 27 дней при демонстрации возможности полета на одном моторе, - лопнула тяга управления, после чего Ente сорвался в штопор. На втором прототипе установили моторы Sh.14, крыло уменьшенного размера с дополнительными вертикальными поверхностями. На втором прототипе в 1930 году первый полет выполнил Корнелиус Эдцард.

    На закате карьеры второй F 19 получил гражданскую регистрацию и закончил свою летную жизнь в качестве лаборатории на базе DVL в Берлине-Адлерсхофе. Самолет летал до 1939 года с регистрацией D-1960.

  • Flight 1931-01 / Flight

    29 декабря 1927г.: Георг Вульф, один из основателей компании "Focke-Wulf", погиб, выполняя публичный демонстрационный полет на своем перспективном самолете схемы "бесхвостка" ("утка") - Focke-Wulf Fw 19.
    "TAIL FIRST": In this view of the Focke-Wulf "Ente" in flight can be seen the undercarriage, the outboard fins, and the very large fin and rudder.

  • Мировая Авиация 132

    Выполнивший первый полет в конце 1930 года, второй F 19 выставили в музее "Deutsche Luftfahrtsammlung" в районе Берлин-Моабит. Самолет был уничтожен в 1944 году налетом авиации союзников.

  • Flight 1930-10 / Flight

    AN INTERESTING EXPERIMENT: The Focke-Wulf Co. of Bremen recently completed a second "Ente" or "tail-first" machine, which has now passed its type tests and is said to fulfil all the claims made for it. With the tail first arrangement the machine is made proof against stalling and spinning, while the general arrangement is such that the machine cannot be turned over on the ground, so that the wheel brakes may be applied with full force.

    COMING OR GOING?: The "Ente" in flight. Note the plan form of the front plane.

    AN OLD IDEA REVIVED: The view of the Focke-Wulf "Ente" during its visit to Hanworth. In the photograph the machine is climbing, but not nearly as steeply as it did on some occasions.

    THE FOCKE-WULF "ENTE": Three-quarter front view. Note the negative angle of incidence when the front wheel is on the ground.

  • Flight 1927-09 / Flight

    THE FOCKE-WULF "ENTE": Three-quarter rear view. To get the side areas correct, a very large fin is necessary.

  • Flight 1930-05 / Flight

    A NEW FOCKE-WULF "ENTE": The latest model, flown for the first time the other day, resembles the previous machine, but the addition of outboard wing rudders will be noted.

    The Focke-Wulf F 19A Ente, D 1960, seen here shortly after completion in 1930 with, on the left, Prof. Heinrich Focke and company chief pilot Edzard. Often during this period, such things as the A suffix to the design number inferred nothing more drastic than some slight modification, or engine upgrade to the same machine. Not so in the case of the F19, where the A actually signifies radical, if not immediately obvious changes to the aircraft - a point lost on a number of latter-day commentators, who are clearly unaware of the existence of the first F19. First flown on 2 September 1927, the FI9 canard was aimed at the still embryonic air taxi/feederliner market and, as such, carried a pilot and up to three passengers. Powered by two 75hp Siemens Halske Sh II radials, the F19 cruised at 80mph and incorporated one quite novel purported safety feature that was to lead to the death of Georg Wulf, Director, Chief Pilot and co-founder of the company. Included within the parasol mounted foreplane of the F19 was a pivoting mechanism that allowed the foreplane to tilt side-to-side. The purpose of this tilting foreplane, according to the patent held by Prof. Focke, was to ease pilot control problems in the case of losing an engine. According to one knowledgeable source at the time, this tilting device had one drawback, it did not work in one particular set of circumstances. Apparently aware of this flaw, Georg Wulf, who had thoroughly tested the F19 over the past three weeks, took it aloft for a demonstration flight in front of potential buyers on 29 September 1927. During the course of this demonstration, made at low level, Wulf encountered whatever the problem was and although he nearly retrieved flying speed and control, the machine struck the ground killing him. The second machine, the F19A could be readily differentiated from the first by its underwing fins. Not so immediately apparent was the absence of the tilting mechanism from the now fixed foreplane. Thus modified, the sole F19A was to continue flying throughout the 1930s, ultimately retiring in 1939.
    Inset Georg Wulf, who, with Prof. Heinrich Focke, founded the Bremen-based Focke-Wulf Flugzeugbau in January 1924.

    WILL IT COME TO THIS?: A FLIGHT Artist's conception of the result of combining three types which seek to avoid stalling and spinning; the Autogiro, the "Ente" and the Pterodactyl. The name might be something short and snappy, like "Pteroautogirentedactyl."
