The Arado Ar 79 high-performance side-by-side two-seat cabin tourer was designed by Dipl.Ing Walter Blume in 1937, and made its debut in 1938, promptly establishing a number of international class records. On 15 July 1938, the first example, the Ar 79A V1 D-EKCX flown by Herr Lüber set a new 1 000km record in its class with an average speed of 229,04 km/h, and two weeks later, on 29 July, the Ar 79A V2 D-EHCR flown by Seelbach, established a 2 000-km record with an average speed of 227,029 km/h. A more ambitious flight began on 29 December 1938, when D-EHCR, piloted by Oblt Pulkowski and Ltn Jennett, was flown non-stop from Benghazi, Libya, to Gaya, India, a distance of 6903 km at an average speed of 160 km/h. For this flight, the aircraft was fitted with a 520 l fuel tank in the fuselage and a 106 1 auxiliary tank beneath the fuselage.

The Ar 79 was of mixed construction, the fuselage being a welded steel tube structure and an Elektron monocoque aft, and the single-spar wing being a wooden structure with plywood and fabric skinning. Power was provided by a 105 hp Hirth HM 504A-2 four-cylinder inverted inline engine and all three undercarriage members were retractable.

A total of 48 Ar 79s was built in B, D and E versions, the sub-types differing in only minor respects of equipment, etc, production terminating in 1941, and a number being utilised for liaison duties by the Luftwaffe. At least one example - the 47th built - survived WWII and is still flying with the Lufthansa Historical Flight. An Ar 79B-l, this aircraft was registered D-ECUV.

Arado "Ar 79u" Training and Touring Aircraft

The new model, released by the Arado aircraft factory, three of which participated in the Deutschlandflug, is designed as a cantilever low-wing monoplane with two adjacent seats.
The three-part wing has a trapezoidal outline and a slight V-shape. The center section, firmly attached to the fuselage, is covered with sheet metal, while the
eye sections are fabric-covered. The wing-fuselage transition is lined.
The fuselage has a rectangular cross-section with rounded edges at the front and becomes almost circular further back. Smooth sheet metal monocoque construction with light transverse stiffeners.
Enclosed cabin with two adjacent seats, covered by a sliding canopy. The front section of the side windows is extended particularly far down to improve visibility to the front and below.
Cantilever tail unit in the shape familiar from other Arado models. Continuous horizontal stabilizer at the rear. The fuselage end, in front of which is the keel fin, firmly attached to the fuselage, with the rudder mounted on two bearings. Elevator with trim tab.
Retractable landing gear at the outer ends of the wing center section. The wheels are mounted on cantilevered spring struts, which are bent laterally at the lower end and raised inward. The struts are positioned in the wing nose, while the wheels are positioned in the fuselage floor. Pivoting tailwheel.
Powerplant: Air-cooled Hirth "HM 504" inline engine with 105 hp maximum power.
The aircraft is normally equipped with the four-cylinder Hirth "HM 504". The lighter "HM 60 R" with 80 hp can also be used on request.
With the two 60-liter tanks, the normal range is more than 1,000 km. The wide track width of the undercarriage (2 m) is noteworthy, which, together with the lockable tailwheel, results in good roll characteristics.
The wing is constructed of wood. A spar with an attached plywood nose absorbs the forces. The skin is partly made of plywood and partly of fabric.
Wingspan 10 m, length 7.6 m, height 2.1 m, area 14 m², empty weight 460 kg, take-off weight 760 kg, wing loading 54 kg/m², power loading 7.25 kg/hp,
maximum speed (as flown) 230 km/h, cruise speed 205 km/h, climb time to 1000 m 3.7 min, to 2000 m 8.2 min, effective ceiling 5500 m, landing speed
74 km/h, range 1025 km, fuel consumption 11 1/100 km.
