Do-19

Long Range Heavy Bomber

Dornier

Do-19V1

Do.19, structurally, especially in comparison with Do.17, was distinguished by a rectangular fuselage section and a thick wing with a wide chord. The fuselage was a riveted monocoque. The wing with two steel spars was sheathed with a metal sheet. The spaced plumage was with one strut. All three landing gear retracted, the main landing gear into the internal engine nacelles. The crew was planned to consist of nine people: a pilot, a pilot-navigator, a bombardier and five gunners. Defensive armament included a forward bombardier's turret with an MG-15 machine gun, a similar machine gun in the tail, and two large hydraulically controlled two-crew turrets each above and below with 20mm cannons. The bomb bay could hold up to 16 100kg or 32 50kg bombs. All fuel was placed in the center section.

The first experimental Do.19-V1 (D-AGAI) flew on October 28, 1936. The power plant consisted of four Bramo (Siemens)-322H 9-cylinder air-cooled engines with a take-off power of 715 hp. and 600 hp at face value. Armament was not mounted. The V2 was planned under the BMW-132F with 810 hp at takeoff and 650 hp at nominal. It was planned to install weapons on VZ. However, the double tower - one crew member controlled the tower horizontally, the second - vertically - designed in parallel with the aircraft, turned out to be heavier and more cumbersome than one could accept. Static tests have shown that the installation of towers will require a significant strengthening of the structure of the central section of the fuselage. The weight already got out beyond the power of the power plant.

There was no other turret to install, but Dornier proposed a more powerful production Do.19a model with four 900 hp Bramo-Fafnir-323A-1 engines. on takeoff and 1000 hp. at an altitude of 3100 m. It was planned to install lighter towers. Take-off weight was estimated at 19 tons, speed up to 370 km / h and range up to 2000 km, a height of 3000 m was gained in 10 minutes, and a ceiling of 8000 m.

Meanwhile, on June 3, 1936, General Wefer died. His successor, Lieutenant General Kesselring, decided to revise the program in favor of a smaller, twin-engine bomber. The requirements for such a bomber were transferred to Heinkel, which began work on the He.177. At that time, the main goal of the Luftwaffe was determined more on a tactical than a strategic level. Given the limited capabilities of the German aircraft industry, the heavy bomber could only be produced to the detriment of fighters and tactical bombers. Thus, despite the protests of the Technical Department, on April 29, 1937, all work on the aircraft was officially stopped.

The nearly finished Do.19 V2 and the half-finished V3 were scrapped. Do.19 V1 survived, in 1939 it was converted into a transport aircraft and accepted into the Luftwaffe, where it was used in the Polish campaign.
