Aviatik D.I (Berg D.I)

1917 WORLD WAR 1

History

In the last years of the First World War, Aviatik D.I served as a fighter and reconnaissance escort for the Austro-Hungarian Empire. After pointing out the inherent flaws of the original design, the system ultimately proved to be a combat aircraft with good speed, climbability and service limits.

The D.I was developed to replace the Hansa-Brandenburg D.I series (biplanes designed by Ernst Heinkel, introduced in 1916 and left a legacy of excellent but fatal accident-prone). Still, D.I fought until the end of World War I and produced more than 700 examples.

The Aviatik D.I was the first Austrian-designed fighter jet to be built entirely in Austria.

The D.I entered service as a prototype in August 1916 and made its first flight on January 24, 1917. However, the test flight ended fatally and at the cost of the test pilot's life.

As a result, the original design was modified to compensate for the deficiencies, and three more prototypes soon emerged, each with a specific development purpose, as well as an 8mm Schwartzloss machine gun mounted on the upper wing assembly. After additional testing, production aircraft were ordered and delivered - these were equipped with synchronized (via propeller breaker gears) 2 x 7.92mm forward-firing Schwartzloss machine guns on top of the engines.

In terms of design, the Aviatik D.I is a traditional single-seat biplane layout. The wings are mounted in a staggered up and down arrangement of equal spans, with parallel struts and separate compartments.

The engine - a 200-horsepower Austro-Daimler water-cooled in-line engine - was mounted in the forward-most section of the fuselage and drove a two-bladed propeller. The landing gear is fixed and consists of two main wheels and a tail skid. The roomy cockpit is amidships behind the engine, offering relatively good visibility (as good as a biplane).

The pilot sits behind the upper wing assembly (relatively close to the top of the engine compartment) behind a simple windshield in the open air cockpit. The fuselage tapers towards the empennage, with a large vertical fin and applicable horizontal plane.

Performance specs include a top speed of 115 mph, a service ceiling of approximately 20,100 feet, and a total run time of 2 hours and 30 minutes.

While the main manufacturing of Aviatik D.I was taken over by Aviatik Austria, several factories also licensed production during his tenure. These include Lohner, Lloyd, MAG, Thone and Fiala, and WKF, which have different series names, the main difference being the horsepower output of their chosen Austro-Daimler engine. A total of about 700 types were produced from 1917 to 1918.

Deliveries began in the fall of 1917 and continued until October 1918.

In service, early Form D.s showed engine overheating issues and structural defects (i.e. fabric tearing in the underbody or loss of parts and wings at high speeds). The cannon on the original production model was also well out of the pilot's reach, meaning a jammed cannon would remain stuck until the pilot landed his mount for repairs. As production continued, the structure gained traction in some areas and was enhanced based on feedback from the pilot.

Also, the gun is now moved into the pilot's range. Just fly without the hood to fix on-site engine overheating issues.

Aviatik D.I also runs under the famous name "Berg Fighter" or "Berg D.I" in reference to its designer Julius von Berg. Until the end of the war, the Austro-Hungarian Air Force used their D.Is heavily.

The D.I comes in a modified form of the D.II with a cantilevered low-wing aircraft. The D.II was produced in limited quantities in two batches from 1918, but arrived too late to see any useful supply of combat units. The D.I is also considered a few other notable "one-off" prototype forms - chiefly the D.III, a high-altitude variant with a 230-horsepower Hiero engine, and the Dr.

I, a three-wing design based on the D.I twin.
