Design Problems and Methods for Large Flying Boats 350102

AFTER citing the improvements achieved in the S-42 as compared with the S-40 type, the author states that many future improvements will be made in flying boats as a result of improved engines, propellers and airplane design.
Some of the general problems of flying-boat design are compared with those of land air-transports. Although in the basic phases the problems are similar, the flying-boat designer diverges from the land air-transport-designer's viewpoint in several important features such as cruising range, speed, comfort, space per passenger, and size.
Many advantages, particularly in seaworthiness, are found in connection with the construction of larger-sized ships, as the inherently easier take-off of the larger flying boat permits better shapes for seaworthiness. Sharper and more refined V-bottom hulls will be used.
It is stated that the development of flying boats is of great importance, particularly to the United States, as it offers a basic means of rapid contact with the major part of the world.
