Arado Ar 66
The Arado Ar 66 was a German single engine, two seat training biplane, developed in 1933.
It was also used for night ground attack missions on the Eastern Front.
The Ar 66 had an Argus As 10 air cooled inverted V8 engine producing about 179 kW (240 hp), which drove a 2.5 m (8.2 ft) two blade propeller.
It carried 205 L (54 US gal) of fuel, and 17 L (4 US gal) of oil.
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 and an 8° sweep.
Construction consisted of a double pine wing spar structure, with lime tree ribs, and fabric covering.
There were ailerons in both the upper and lower wings.
The tail had a conventional design, with the horizontal stabilizers mounted on the fuselage upper edge. The rudder was placed behind the elevators.
Both the rudder and the elevators 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 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.
