| has gloss | eng: The Curtiss N-9 was a seaplane variant of the Curtiss JN-4 "Jenny" military trainer used during the First World War. As a seaplane, the N-9 was equipped with a single central pontoon mounted under the fuselage. A small float was fitted under each wingtip. With the additional weight of the pontoon, a number of structural and aerodynamic changes were required, the design of which made use of wind tunnel data developed at the Massachusetts Institute of Technology, meaning the N-9 was the first US Naval aircraft to incorporate wind tunnel data directly into its design. The wingspan was stretched an additional 10 ft ( m), the fuselage was lengthened, the tail surfaces were enlarged, and stabilizing fins were added to the top of the top wing. The N-9 was initially powered by a 100 hp (75 kW) Curtiss OXX-6 engine. |
