Design and development

The Albatros was a wooden glider with a cantilever mid-set wing. The wings had a root chord of 1.60 m (5 ft 3 in), tapering to 0.66 m (2 ft 2 in) at the tip and carried 1.50° of dihedral. They were built around a single spar with a plywood covered leading edge torsion box in front of it and fabric covered behind. The wing carried wooden, fabric covered ailerons and airbrakes.[1]

The fuselage of the Albatros was a plywood monocoque and the empennage was also wooden and fabric covered, with the tailplane set at the top of the fuselage. The occupants sat in tandem under a continuous canopy with two separately sideways opening sections. It had a fixed undercarriage with two wheels on a short axle under the fuselage and an integral nose skid. At rest, it sat on its wheels and tail.[1]

The Albatros first flew on 1 June 1958. In all, 25 were built.[1]

gollark: `errno.h` is unnecessary because osmarkslibc functions are incapable of failure.
gollark: `stdarg.h` seems bad, functions should only have one arity.
gollark: `stdatomic.h` is unnecessary if we just remove threading.
gollark: `stdio.h` goes against functional purity so that can be dropped.
gollark: `uchar.h` and `wchar.h` are probably unnecessary, just make everyone use ASCII.
