Английская Википедия:Hall XP2H
The Hall XP2H-1 was an American prototype four-engined biplane flying boat of the 1930s. Intended as an experimental very-long-range maritime patrol aircraft, a single example was built. The XP2H-1 was the largest four engine biplane aircraft ever procured by the US Navy.[1]
Development and design
In 1930, the United States Navy ordered a single example of a large flying boat from the Hall-Aluminum Aircraft Corporation, to meet a requirement for an experimental very-long-range patrol aircraft. The resulting design, designated XP2H-1, was a four-engined biplane with an all-aluminum hull, scaled-up from the smaller PH flying boat, which accommodated a crew of six. The wings were of fabric-skinned aluminum construction and were of trapezoidal shape. The water-cooled V-12 Curtiss V-1570 Conqueror engines were mounted in tandem push-pull pairs between the wings, in nacelles attached to the lower wings.[2][3]
The XP2H-1 first flew on November 15, 1932, and was extensively tested, demonstrating excellent performance, being Шаблон:Cvt faster than predicted.[4] It was possible to cruise on just two engines to extend range, and in 1935, the XP2H-1 was used to carry out a nonstop flight between Norfolk, Virginia and Coco Solo, Panama Canal Zone. The XP2H-1 took 25 hours and 15 minutes to fly the Шаблон:Cvt distance between these two locations.[5] It was destroyed later in the year attempting to alight in open water.[6] No further P2Hs were built, with the US Navy equipping its patrol squadrons with smaller flying boats such as the Consolidated P2Y.
