Dornier Rs.II

During World War I German engineer Dr Claude Darnier produced the first of the flying boats that would eventually win him fame. These giant aeroplanes reflected his abiding interest in metal as a material for aircraft construction, as well as his desire to work on a grand scale.
The Rs.I, which Dornier built at the Zeppelin-Werke Lindau on Lake Constance in 1915, was the world’s largest aircraft at that time, but, unfortunately, it was wrecked before trials could begin.
His second flying boat, the Rs.II, first flew in June 1916. This was effectively a parasol monoplane, for the lower wings were mere
stubs to avoid an unfortunate tendency for the lower wingtips to “dig in” to the water during a swell.
The hull was mainIy metaI-skinned and the tail surfaces were carried on a tubular open girder extending from its rear. The fabric-
covered wing was supported by massive pairs of vee struts on each side. Initially, three engines were housed in the hull, driving the pusher propellers.
When flying test s proved unsatisfactory, the Rs.II was extensively rebuilt with four engines in tandem pairs mounted between the wing and t he hull.
In tests the aircraft proved seaworthy and flew well. However, in August 1917 the Rs.II was damaged and duly scrapped.
