Avia BH-26

Прототип истребителя-разведчика выполнил первый полет в 1927 году и стал первой попыткой конструкторов фирмы "Avia" спроектировать двухместный истребитель. Как и на ранних самолетах Бенеша и Хайна, на нем имелся только руль направления - неподвижный киль отсутствовал. Опыт выявил необходимость установки киля, который появился уже на серийных машинах.
  На нижнем крыле установлены элероны большого размаха с аэродинамической компенсацией в виде небольшой поверхности, прикрепленной к элерону на трех кронштейнах. Есть данные, что для ВС Чехословакии было построено восемь серийных BH-26, но они не поступили в части первой линии.

The Paris Aero Show 1926


  THIS well-known Czecholovak firm is exhibiting two aeroplanes, the little Avia B.H.11 with Walter engine, and a two-seater fighter, the Avia B.H.26.
  The Avia B.H.26 two-seater fighter is fitted with a "Jupiter" engine and is a biplane of normal design, with a single bay in the wing cellule and "N" interplane struts. The top plane is, however, of slightly smaller span than the bottom. The wing construction is normal, with box spars and wood ribs. The covering is three-ply wood up to the rear spar, the whole afterwards fabric-covered. The ailerons are of welded steel-tube construction and are fitted to the lower plane only.
  The fuselage is of the ply-wood covered box type, without internal bracing wires. The pilot's cockpit is in front, and is equipped with all the usual instruments, as well as with two fixed Vickers guns firing through the propeller, while the gunner has the usual gun ring for his two Lewis guns. Space is provided for 600 rounds of ammunition for the Vickers guns and 1,000 rounds for the Lewis guns. The main petrol tank is inside the fuselage, between the fireproof bulkhead and the pilot's cockpit.
  The undercarriage is of the Vee type, the rear legs being telescopic and fitted with rubber blocks working in compression.
  Specification of Avia B.H.26.- Wing span bottom plane, 10-8 m.; top plane, 10-2 m.; length overall, 8-78 m.; wing area, 31-32 sq. m.; weight of machine empty, 1,060 kg.; fuel and oil, 220 kg.; crew and equipment, 420 kg.; total loaded weight, 1,700 kg.; duration, 2 hrs. Top speed, 240km./hr,; stalling speed, 90 km./hr. Climb to 5,000 m. in 20 mins. Ceiling, 7,000 m.

  The other Avia machine, the type B.H.26, is a two-seater fighter fitted with "Jupiter" engine. As far as we are aware, this is the first two-seater fighter of Czechoslovak design and construction to be fitted with this engine, and certainly Messrs. Benes and Hajns have produced a very business-like aeroplane. The B.H.26 is of perfectly standard Avia design, and there is little in the details of the construction which calls for comment. Now that the firm of Milos Bondy A Spol has been taken over by the famous Skoda works, presumably more capital will be available for development work, and the two clever and energetic designers of the firm may be relied upon to rise to the occasion and to produce machines which shall worthily uphold the excellent reputation which the firm in its smaller form has already established.
The BH-26 was Avia's first attempt to produce a two-seat fighter, and, built in small numbers, it entered service as the B 26 in the late 'twenties.
