GALLAUDET D-2
Great aerodynamic efficiency was claimed for this aeroplane, with its two 150 h.p. Dusenberg engines buried in the fuselage. Both were connected to a four-blade propeller that was mounted on a ring completely encircling the fuselage aft of the wing. Company advertising claimed a cruising speed of 100 m.p.h. on two engines and 70 m.p.h. on one. While the Army bought only four, similar models were also sold to the Navy, which developed the design further, replacing the twin Dusenbergs with a single Liberty. This improved D-4 model was used as a Naval racer in early post-war years.

J.Herris - Weird Wings of WWI /Centennial Perspective/ (70)
The Gallaudet D-1 two-seater had two Dusenberg engines of 150 hp buried in the fuselage in an unusual mounting. The Navy ordered it to test its unusual engine and propeller configuration. The performance was poor and it had a number of technical problems, although the structure was well-built and there were no problems with the engines or drive system.

AN INTERESTING EXAMPLE OF A PUSHER FUSELAGE BATTLE SEAPLANE FROM AMERICA - The principal features of this machine, which has been built by the Gallaudet Co. of Norwich, Conn., for the U.S. Navy, consist of the arrow-form wings, and the four-bladed propeller (driven by two 150 h.p. Duesenberg motors) bisecting the fuselage. A clutch connection between each engine and the propeller enables either one or both engines to be used. A speed of 100 m.p.h. is claimed with both engines running, and 70 m.p.h. with one engine. Machines embodying this form of propulsion were designed several years ago by M, Coanda (Bristol), and M. Pateras Peseara, both of which were tested at M. Eiffel's laboratory, whilst other examples are to be found in the Borel and Bleriot pusher monoplanes of 1912-3, and the Grahame-Whlte Military biplane of 1913.
