В.Обухович, А.Никифоров Самолеты Первой Мировой войны


После победы на втором конкурсе истребителей моноплана-"парасоль" Фоккер D VIII к созданию подобных аппаратов приступили и некоторые другие компании. Так, конструктор компании "Кондор" Вальтер Ретхель (будущий ведущий конструктор Me 109) в середине 1918 г. разработал истребитель Е.З. От машины Фоккера новый самолет отличался конструкцией крыла. Оно было цельнодеревянным толстого профиля с фанерной обшивкой. Листы обшивки снаружи (по нервюрам) усиливались Л-образными накладками. Фюзеляж конструктивно напоминал Фоккера D VIII: сварная ферма из стальных труб скруглялась фанерными панелями и частично оклеивалась полотном. Киль был деревянным, силовой набор стабилизатора из стальных труб. Оснащался самолет мощным ротативным двигателем Оберурсель Ur.III (160 л. с.) в стандартном, для подобных двигателей мотокапоте. На варианте Е.3а устанавливался двигатель Гебель Goe.III в 200 л. с, укрытый оригинальным капотом.
  Самолет G.3 участвовал в конкурсе истребителей, где продемонстрировал отличные характеристики, а также удивил прочностью конструкции. Летчики-истребители высоко оценили эту машину.
  Командование заказало 100 истребителей, получивших обозначение DI. Вооружались они двумя синхропулеметами "Шпандау*. Однако до конца войны удалось поставить в войска не более 10 машин, которые в боях не участвовали.

Kondor E III and IIIa
  A parasol monoplane in two versions was designed by Rethel and Ehrhardt to participate in the third D types Competition in October 1918. The E III was fitted with 140 h.p. Oberursel U III engine and had a cut-away horse-shoe-type cowling; the E IIIa (above) had the 200 h.p. Goebel IIIa, which was enclosed in a circular cowling with louvred vents all round it. Engine, 140 h.p. Oberursel U III (E IIIa), 200 h.p. Goebel IIIa (E IIIa). Span, 9 0 m. (29 ft. 6 3/8 in.). Length, 5.8 m. (19 ft. 0 3/8 in.). Height, 2.745 in. (9 ft. 0 in.). Area, 12.4 sq.m. (134 sq.ft.). Weights: Empty, 465 kg. (1,023 lb.). Loaded, 660 kg. (1,452 lb.). Speed, 195 km.hr. (121.875 m.p.h.), E III; 200 km.hr. (125 m.p.h.), E IIIa. Climb. 5,000 m. (16,400 ft.), 16 min. E III; 11 min. E IIIa.

KONDOR E 3 (D I) Germany

  In July 1918, Walter Rethel initiated design of a single-seat parasol-wing fighter monoplane patterned on the Fokker E V (D VIII) and designated E 3 by the Kondor Flugzeugwerke. A unique cantilever wing construction was devised for the new fighter and patented by Kondor. This consisted of thin veneer sheets laid chordwise across the wing between protruding ribs to which the veneer was attached with opposing L-shaped strips. This wing structure was exceptionally robust and, according to Kondor, the protruding ribs resulted in improved aerodynamic characteristics. Powered by a 160 hp Oberursel Ur III rotary, the E 3 was sent to Adlershof for type test in September 1918, and participated in the Third D-type contest held in the following month. The E 3 was reported as having excellent flying characteristics only marginally inferior to those of the Siemens-Schuckert D IV, and its wing did not oscillate at high speeds as did that of the Fokker D VIII. Hptm Eduard Ritter von Schleich, CO of Jagdgeschwader 4, regarded the E 3 as the best fighter of the competition. A second E 3 (referred to by Kondor as the E 3a) was built with a new 160 hp Goebel Goe III rotary engine, this having a full cowling rather than the cutaway horseshoe-type cowling partly enclosing the Ur III rotary. This version had a max speed of 124 mph (200 km/h) and attained an altitude of 16,405 ft (5 000 m) in 11 min. The Kondor parasol was assigned the official designation of D I, but it is not known with certainty how many were built, although it is believed that 100 fighters of this type were ordered and some 8-10 completed. After World War I, a single E 3a was acquired by the Swiss Comte, Mittelholzer concern for aerobatic displays, two others being procured by the Dutch NAVO firm early in 1920.

Another contender and Fokker D VIII look-alike that took part in the third 1918 Adlershof fighter trial, held in October, was the Kondor E 3a seen here. The E 3A employed a 180hp Goebel rotary. A second specimen, the 160hp Oberursal U III powered Kondor E 3, also participated in this competition. The external wing ribbing, along with the aft wing centre section cut-out help to highlight that this design employed the still novel thick sectioned, high lift wing. Top level speeds for the E 3 and E 3a were reported to be 120mph and 124mph, respectively.
