__. . MAY 15, 1919 |flJB» THE U.S. NAVY FLYING-BOAT, N.C. I THE machines representing America (non-competitive) in the Atlantic flight are the U.S. Navy flying-boats of the N.C. (Navy Curtiss) type, built by the Curtiss Engineering Corpora tion, to the designs supplied by the Bureau of Construction and Repair of the Navy Department. Three of these machines N.C.-i, N.C.-2 and N.C.-3 are, we believe, all of similar type, the engines have, we understand, been made in one or more of the Atlantic machines, such as the location of two screws as tractors and the third as a pusher. As will be seen the N.C.-i is a flying-boat of the short-hull type, with the tail planes carried from the hull and top main planes by means of outriggers. The hull is 44 ft. 8| ins. Three-quarter front view of the N.C. 1 flying-boat Side view of the N.C, 1 flying-boat whilst the fourth machine, N.C.-4, differs in having four engines instead of three. The following illustrations and description of the original N.C.-i type flying-boat should, therefore, be of general interest just now, this particular type differing from the Atlantic machines only in a few modifica tions rendered necessary by the requirements for the long distance flight. Certain alterations in the arrangement of overall length, with a maximum beam across the side-fins of about 10 ft. It has a single step 27 ft. 8| ins. from the nose, and a V bottom. The main planes are built up in seven sections, three (two outer extensions and one centre section) in the top, and four (two outer extensions and two centre sections) in the bottom. The spans of the outer sections are 44 ft. 4 ins. and 35 ft. 4 ins. for the top and bottom planes Rear view of the N.C. 1 Flying-boat 637
