Upon review of numerous proposals, the Aeronautics Division of the U.S. Bureau of Engineering referred recommendations to the Chief of Naval Operations in which to finalize approval of a submission by the Naval Aircraft Factory (NAF) with which to produce a pre-production series of four prototypes at an estimated construction cost of $84,680. Accordingly, the NAF proposal consisted of a twin-engine flying boat which featured a hull design identical to that of the Curtiss NC-1, an armament of four flexible mounting Lewis machine guns, and four crew members. An egg-like nacelle atop the upper wing housed an additional pilot/gunner's position. Initially designated as Twin Fighter (TF), a review of the aircraft's dimensions showed that the wingspan was insufficient for a conventional two-engine layout. Thus, the Bureau of Engineering revised the engine configuration into a tractor/pusher combination mounted on the aircraft centerline. This change altered the designation from ''Twin'' to ''Tandem'' fighter. The TF was designed to incorporate two Curtiss-built Kirkham inline engines, however mechanical problems hindered the development of these power plants, so two Hispano Suiza engines were adopted instead. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Naval Aircraft Factory TF」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
