TheZeppelin-Lindau CL.II was a German single-engine two-seatbiplane with an all metal structure, built byZeppelin-Lindau during World War I.^[1]

Design

[edit]

The CL.I was an all-metal single-bay wire-braced biplane, with a stressed skin fuselage, and fabric covered flying surfaces and represented an intermediate step which would lead to the similar but smaller and more refinedD.I.

Development

[edit]

Following the failure of the CL.I to reach the specified altitude of 5,000 m (16,000 ft), and its crash in February 1918 at Berlin Adlershof,^[1] the CL.Ia was built with a number of changes, which resulted in it being re-designated as the CL.II.^[2]The CL.II had the chord of the top wings increased by 100 mm (3.9 in) and the top wing was raised, increasing the height from 2.835 to 2.95 m (9 ft 3.6 in to 9 ft 8.1 in), while the rudder was redesigned to resolve the sole complaint from the test pilot.^[2]The radiator in the CL.I had been located between the wing spars in the upper wing, offset to the pilot's right, however as the plumbing obstructed the pilot's view, and the radiator reduced the efficiency of the wings, it was relocated to the nose of the aircraft.^[3]

With theZeppelin-Lindau CS.I monoplane andZeppelin-Lindau D.I showing more promise, development of the CL.II was abandoned and the last test flight was made on 14 September 1918.^[4]
