Arado Ar 79
The Arado Ar 79 was a two-seat aerobatic travel and training aircraft with two-blade propeller Starr. With this model were established several FAI speed records in July 1938: 1,000 km by 229 km / h, about 2000 km with 227 km / h
History
1937 succeeded Arado under the design direction of Walter Blume and William of Nees as head of the design office, the development of robust, handy and economical sports and touring aircraft Ar 79 in line with the previous sport aircraft LI and L II
The aircraft initially originated from the prototype D- EKCX and D- EHCR and later three series with improvements to the cell, caused a stir by several record flights.
In the GDR, a remake of the Ar 79 under the name P 101 was planned in 1952. At the scheduled mid- 1954 production run, it came as a result of the popular uprising June 17, 1953 but no longer. In Germany attacked in 1958 Wimmer R -110 ( according to Otto Wimmer an engine manufacturer from Sulzbach ) the design of the Ar 79.
Based on the Ar 79 Walter Flower Designed in 1955 the four-seat all-metal low-wing flower Bl 500, which on 16 March 1957, and its first flight was admitted in April 1958. However, it was not a success due to the high price of 63,000 DM.
Construction
The Ar 79 was designed as a cantilever low-wing monoplane, with continuous split flaps, retractable landing gear and dual control. It was manufactured in composite construction. So was the hull of a truss structure of steel up behind the two adjacent seats, behind a hull which were designed with the magnesium alloy electron. The wings were made of wood. This construction provides a low empty weight and together with the two below the rear luggage compartment 60 liter tanks resulted in a large range of 1,025 km. The fully glazed cabin with low-edged front windows allowed a very good all-round visibility. As price 18,000 Reichsmarks were provided initially.
Use
After participating in the Germany flight, the test pattern D EKCX posted on July 15, 1938 world record with an average speed of 229.040 km / h on a 1,000- km route. On July 29, the pilot Seelbach posted on the D - EHCR over a distance of 2,000 km at an average speed of 227.029 km / h the second world record for Arado.
Story made the D- EHCR under Lieutenant Pulkowski and Lieutenant Jenett than this on a flight to Australia to start on 17 December 1938 a non-stop flight between the cities of Benghazi (Libya) and Gaya (India) with a distance of 6303 km a new long-distance world record lined up, surpassing the old record by more than 2,000 km. After another stopovers in Bangkok, Sumatra and Bali, the pilots reached on January 14, 1939 Darwin and on January 16, 1938 Sydney.
On the return flight to Germany, the D- EHCR crashed on February 10, 1939 during a flight in Madras after the collision with a bird of prey from, while the pilot Pulkowski and an Indian passenger died.
After comparing fly on December 9, 1938 between the Arado Ar 79, the Bücker Bu 131 and the Klemm Kl 35 almost 20 machines were to Hungarian customers ( including Istvan Horthy, Miklos Horthy 's son of the Regent ) delivered.

Aircraft received
The Ar 79 B D - EMVT is issued since the fall of 2001 in the German Museum of Technology Berlin. The aircraft was built in 1939 with the serial number 0047 in December 1939 as penultimate of the first series in Brandenburg- Briest, flew from 1945 in the Saarland for the French High Commissioner (as SL- AAP) and to 1961 in changing owners in Germany. 1961 Fritz Ulmer acquired the machine and took it with her (as D - ECUV ) to 1967 participated in many events. In the summer of 1995, the German Museum of Technology Berlin acquired the Ar 79 B. In a joint project of the German Lufthansa Berlin-Stiftung restored the aircraft on the Hamburg -based Lufthansa and flew it from 1996 to 2001 on flight days.
