Albatros W.3

The Albatros W.3 was a twin engine, biplane, float plane torpedo bomber, delivered to the German Navy in 1916. Only one was built.

Design and development
The W.3 was designed from the outset as a torpedo bomber, a large two bay biplane powered by two 150 hp Benz Bz.III engines in pusher configuration mounted on top of the lower wing; these drove two blade propellers, The wings had straight leading edges, squared tips and almost constant chord, though the upper trailing edge was complicated by cut-outs for the propellers and by ailerons, fitted only to this wing, which increased in chord outwards. There was no stagger, so each pair of interplane struts was perpendicular to the wing; the forward member of each pair was at the leading edge and the other at mid-chord.

The fuselage was flat sided, with two open, tandem cockpits in the nose ahead of the leading edge and deepest between nose and trailing edge, forming a belly which housed the torpedo. Aft, it became quite slender, with a broad chord, triangular fin and rounded, balanced rudder. Twin floats, only about half as long as the fuselage, were mounted on individual sets of struts to allow torpedo release between them.

One Albatros W.3 was built and supplied to the German Navy July 1916. The design was developed into the W.5, five of which were built for the Navy in 1917.
