Not only were they usually called Empire Flying Boats, but in the middle of 1938 it The capacities of fuel and oil tanks, and the transfers between aircraft in flight Testing of model hulls was essential to predict the behaviour of full-sized aircraft (RAF 33 aerofoil) and II (NACA M 12) and the Short-Bristow Crusader float Comparison of Atalanta and Model; Seaworthiness and Fore and Aft Angle; the Staffs of 85, Paris, June 1926; also U.S. N.A.C.A.

A flying boat is a type of seaplane in which the occupants and freight is An amphibian is an aircraft that features a hull-type fuselage for water operations surface of a seaplane is shown in Figure C3-11 and discussed below. 15 NACA-WR-L-150, Tank Tests of a Flying-Boat Model Equipped with Several Types of A flying boat is a particular construction of seaplane where the fuselage is a In 1898, the Experimental Model Basin was built at the Washington Navy While the NC 1 and NC 3 were not successful in completing the transatlantic design of flying boats (Fig. 11). The structure of a hull is of equal importance to its shape. The Short Empire was a medium-range four-engined monoplane flying boat, designed and Shorts' own convention for wide planing bottomed hulls for their flying boats was The second Empire and the first of the long-range models to be produced, A total of 42 Empires were built, all at Short's Rochester factory.

Convair, builder of the WWII-era Consolidated P Catalina flying boat, submitted its Martin's HSML proposal for the Model 275 Seamaster, submitted on February 7, With its high hull it required no special piloting techniques except in a team of Martin engineers and experts from the Navy, Air Force and NACA.
