The Arado Ar 79 was a two-seater aerobatic travel and training aircraft with a two-bladed rigid propeller. With this model, several FAI speed records were set in July 1938 : over 1000 km at 229 km / h, over 2000 km at 227 km / h.

history

In 1937, Arado succeeded in developing the robust, handy and economical Ar 79 sports and touring aircraft based on the earlier L I and L II sports aircraft , under the design management of Walter Blume and Wilhelm von Nees as the head of the design office .

The aircraft, of which the prototypes V1 (D-EKCX), V2 (D-EHCR), V3 (D-EDCG) and later three series with improvements to the airframe were created, caused a sensation with several record flights.

The production of the Ar 79 amounted to 15 pre-series aircraft (W.-No. 3677-3691), which also included the test model. These were delivered by February 1940. In the RLM delivery schedule of April 1, 1939, 100 aircraft of a sales series were planned. This was reduced to 40 (W.-Nr. 21-60) at the beginning of the war and taken over by the Luftwaffe. The delivery took place in the period from November 1939 to April or May 1940. In 1939 two pre-series aircraft were delivered to Hungary.

A new edition of the Ar 79 under the name P 101 was planned in the GDR in 1952. However, due to the popular uprising of June 17, 1953, the series production planned from mid-1954 onwards did not take place. In 1958, the Wimmer R-110 (after Otto Wimmer, an engine manufacturer from Sulzbach) took up the design of the Ar 79 in the FRG .

On the basis of the Ar 79, Walter Blume designed the four-seater all-metal low-wing aircraft Blume Bl 500 from 1955 , which had its maiden flight on March 16, 1957 and was approved in April 1958. However, due to the high price of 63,000 DM, it was not a success.

construction

The Ar 79 was designed as a cantilever low-wing aircraft, with continuous spreading flaps, retractable landing gear and double steering. It was made in mixed construction. The fuselage consisted of a framework made of steel up to behind the two seats next to each other, and behind them a fuselage shell that was lined with the magnesium alloy electron . The wings were made of wood. This construction resulted in a low empty weight and, together with the two 60-liter tanks located under the rear luggage compartment, a long range of 1025 km. The fully glazed cabin with the front windows pulled far down enabled a very good all-round view. The initial price was set to be 18,000 Reichsmarks.

Press release in the Rostocker Anzeiger from July 19, 1938

After all three prototypes took part in the Germany flight from May 22 to 29, 1938, the test model D-EKCX with pilot Lüber achieved a world record on July 15, 1938 with an average speed of 229.397 km / h on a 1000 km route. On July 29th, the pilot Seelbach set the second world record for Arado on the D-EHCR over a distance of 2000 km at an average speed of 227.029 km / h.

The D-EHCR made history under Lieutenant Pulkowski and Lieutenant Jenett when it was on a flight to Australia starting on December 17, 1938 on a non-stop flight between the cities of Benghazi ( Libya ) and Gaya ( India ) with a distance of 6303 km set a new long-distance world record that exceeded the old record by more than 2000 km. After further stopovers in Bangkok , Sumatra and Bali , the pilots reached Darwin on January 14, 1939 and Sydney on January 16, 1939 .

On the return flight to Germany, the D-EHCR crashed on February 10, 1939 on a sightseeing flight in Madras after colliding with a bird of prey, killing the pilot Pulkowski and an Indian passenger.

After a comparison flight on December 9, 1938 between the Arado Ar 79, the Bücker Bü 131 and the Klemm Kl 35 , almost 20 machines were delivered to Hungarian customers (including István Horthy, the son of the Reich Administrator Miklós Horthy ).

Received aircraft

The Ar 79 B D-EMVT has been exhibited in the German Museum of Technology in Berlin since autumn 2001 . The aircraft with the serial number 0047 was built in December 1939 as the penultimate of the first series in Brandenburg-Briest , flew in Saarland from 1945 for the French high commissioner (as SL-AAP) and until 1961 with changing owners in Germany. In 1961 Fritz Ulmer acquired the machine and took part in many events with it (as D-ECUV) until 1967. In the summer of 1995, the German Museum of Technology Berlin acquired the Ar 79 B. In a joint project, the Deutsche Lufthansa Berlin Foundation restored the aircraft on the Lufthansa base in Hamburg and flew it on flight days from 1996 to 2001.
