Drawing of the pigeon

The Etrich Taube , often also called Etrich II Taube in literature , is an aircraft developed by the Austrian aviation pioneer Igo Etrich . The aircraft of this type built by the Rumpler works in Berlin were also marketed under the name Rumpler Taube . It is one of the first types of aircraft to be built in large numbers.

history

After several years of development, Etrich completed the Etrich I in 1909 . It was created by converting a tail and hullless glider and "flew on November 29, 1909 over the entire length of the airfield in Wiener Neustadt ". In the winter of 1909/1910, the sum of his experiences resulted in the new design of the Etrich II Taube , a motorized airplane with a fuselage, which made its first flight on April 6, 1910.

Karl Illner , an employee of Etrich, won the price for the first flight from Vienna to Horn and back on a pigeon in October 1910 .

Etrich founded the Etrich-Flieger-Werke in Lubawka (then Liebau in Silesia) on February 28, 1912 , where Heinkel was also employed as a designer. On August 24, 1913, a pigeon flew over the Giant Mountains for the first time - Etrich flew with his pilot from Liebau in an arc over the mountains to Upper Old Town (today Horní Staré Město , a district of Trutnov ), where he came from, and immediately back to Liebau.

The aircraft was later built under license by Rumpler-Werke in Germany under the name Rumpler-Taube . The Rumpler-Werke stopped paying the license fees after a short time. Igo Etrich considered a lawsuit, which he dropped because of the expected length of the proceedings and the outbreak of the First World War . He released the prototype, whereupon more than 40 companies manufactured variants of this type under their own names. The pigeon was used in Germany , Italy and Austria-Hungary .

technology

The aircraft was a monoplane with external wire bracing and an auxiliary spar ("bridge") running under the wing. It had no ailerons and no wing flaps . It was controllable in all three axes by twisting the surface . The chassis was steerable and had a ground brake on the middle runner.

The pigeon flew extremely stable thanks to the wing shape based on the shape of the seeds of the Zanonia vine . One of the instructions from the flight instructors in Wiener Neustadt to their students was that if they should get into difficult flight situations, they should simply let go of the controls until the pigeon flew stable again by itself. An anecdote reports that a mechanic inadvertently pushed the throttle of a pigeon to full throttle while preparing to take off and fell out of the plane. The aircraft took off automatically without a pilot and, after the fuel was used up, landed on a meadow after 200 km.

Nevertheless, the machine was considered difficult to fly and land because it required great physical exertion to turn and maneuver.

The steel pigeon , which was developed and built for military use from 1912 onwards, had a hull made of steel tubes. This version was the only one that withstood the stress tests introduced for military aircraft in 1913.

construction

The fuselage was made of wood with fabric covering.

The plane was a braced shoulder wing . The tensioning took place via tombstones that were attached above and below the wing. The wings were fabric-covered bamboo frames . The transverse steering was done by twisting the wing tips.

The tail unit was also made of bamboo with fabric covering.

The aircraft had a rigid landing gear with a continuous axle and a tail spur. The wheels were suspended.

use

The Etrich Taube, also known as the Etrich Monoplan , was seen at many air shows and sightseeing flights of its time.

Because of its stable flight characteristics, the pigeon was a training aircraft and was used privately.

The pigeon was well suited as a scout - the wings were largely transparent, so that the aircraft over 400 m height were difficult to see from the ground. The French called the airplane model the "invisible airplane".

On November 1, 1911, the first military operation of an Italian pigeon took place in Libya , using a pistol and 2 kg bombs. The bombs were dropped by hand by the pilot Giulio Gavotti . At the beginning of the First World War the pigeon was also used. During the Battle of Tannenberg pilots clarified the situation of the Russian army with the help of pigeons . In 1914 it was also used to drop bombs and propaganda material on Paris .

On August 25, 1914, a pigeon was forced to land by a British machine. This marked the Royal Flying Corps ' first aerial victory .

Since the pigeon was slow and difficult to turn, it was withdrawn from the front just six months after the start of the First World War and was only used as a training aircraft.

Gunther Plüschow became famous in 1914 with a pigeon in the German colony of Kiautschou in China . He flew reconnaissance flights over the city during the siege of Tsingtau for over two months until the Japanese took the city in November 1914. It was called "The Eye of Tsingtau". He fled to China by plane and, after nine months of adventurous escape, he returned to Germany in 1915.

production

Since the model could be reproduced without paying license fees, more than 40 companies manufactured this type, which more or less changed it over time. The design changes affected all components of the machine: the motorization, the frame (the steel pigeon had a steel frame), the wing and the controls, which were implemented by "normal" rudders instead of twisting mechanisms.
