variants with their own articles =The Arado Ar 66 was a German single-engined, two-seat training biplane, developed in
1933 . It was also used for night ground-attack on the Eastern Front. It was engineerWalter Rethel 's last design in collaboration with Arado.Design and development
Arado's chief designer Walter Rethel started design of a new two-seat trainer in
1931 , with the design being developed by Walter Blume when Rethel transferred toMesserschmitt , with the first prototype, the Ar 66a flying in 1932 Smith and Kay 1972] .The Ar 66 had an
Argus As 10 air-cooled invertedV8 engine producing about 240 hp, which drove a 2.5 m double-bladedpropeller . It carried 205 litres of fuel, and 17 litres of lubricant.The fuselage had an oval cross-section and was made of welded steel tubes, covered with fabric. The double wings provided very high lift, even at low speeds. Both wings had the same span with an eight degrees sweep. Construction consisted of a double pine cross-beam structure, with lime tree ribs, and fabric covering. There were ailerons in both upper and lower wings. The tail had a conventional design, with the horizontal stabilizer mounted on the fuselage upper edge. The rudder was placed behind the elevator. Both the rudder and the elevator were of steel tube covered in fabric, and had a bigger surface than the first version to correct balance problems. The steel tube undercarriage was attached to the fuselage in a "V" shape and used a high pressure rubber suspension.
The crew consisted of two: instructor pilot and trainee, seated in open tandem cockpits equipped with dual controls. The aircraft was equipped with instrument flight systems with photographic cameras were mounted as optional equipment.
Operational history
The Arado Ar 66 entered service with the
Luftwaffe in 1933, serving as a trainer until well into the Second World WarSmith and Kay 1972] . In 1943, the Luftwaffe set up a number of night harassment groups to operate on the Russian front. The Ar 66, along with theGotha Go 145 , formed the main equipment of these groupsSmith and Kay 1972] .Variants
;Ar 66A: Used in the new
Luftwaffe as a trainer.;Ar 66C: Modified elevators, larger rudder, and larger diameter wheels.;Ar 66B: Seaplane version of Ar 66C. Two large steel hollow floats braced with iron cable. About ten were constructed and used for seaplane training.Operators
