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.''Test Pilot'' Airpower, September 1974 pp. 11-12 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.Wegg 1990, pp.113-114.''Flight' ...

Consolidated P2Y
The Consolidated P2Y was an American flying boat maritime patrol aircraft. The plane was a parasol monoplane with a fabric-covered wing and aluminum hull. Development Initially created to compete for a U.S. Navy contract dated February 28, 1928, the prototype Model 9, XPY-1, was designed by Captain Dick Richardson and Isaac M. 'Mac' Laddon. Beginning construction in March 1928, the aircraft was ready for its first flight by the end of the year. Lieutenant A. W. Gorton made the first flight out of Anacostia NAS, Washington, D.C.Donald 1997, p. 268. The production contract was opened to other bidders, and the Glenn L. Martin Company undercut them and was awarded the contract to construct the plane as the Martin P3M-1 and P3M-2. Three P3M-1s and six P3M-2s were built; one XP2M-1 was also built to a similar design, powered by three Wright Cyclone engines; following the removal of the third engine it was redesignated XP2M-2. The idea of a third engine on the XPY-1 had been stud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hall Aircraft
In architecture, a hall is a relatively large space enclosed by a roof and walls. In the Iron Age and early Middle Ages in northern Europe, a mead hall was where a lord and his retainers ate and also slept. Later in the Middle Ages, the great hall was the largest room in castles and large houses, and where the servants usually slept. As more complex house plans developed, the hall remained a large room for dancing and large feasts, often still with servants sleeping there. It was usually immediately inside the main door. In modern British houses, an entrance hall next to the front door remains an indispensable feature, even if it is essentially merely a corridor. Today, the (entrance) hall of a house is the space next to the front door or vestibule leading to the rooms directly and/or indirectly. Where the hall inside the front door of a house is elongated, it may be called a passage, corridor (from Spanish ''corredor'' used in El Escorial and 100 years later in Castle H ...

1930s United States Patrol Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 '' Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Flying Boats
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Short Sarafand
The Short S.14 Sarafand was a British biplane flying boat built by Short Brothers. It was planned as a general reconnaissance aircraft for military service. When it was built in 1932 it was the largest aeroplane in the United Kingdom. The Sarafand was first proposed by Oswald Short in 1928 as an enlarged development of the Singapore II, to provide transatlantic range capability. Short managed to persuade first his chief designer Arthur Gouge and then the Chief of the Air Staff, Sir Hugh Trenchard (later Viscount Trenchard) of the feasibility of such a large aircraft and Air Ministry specification R.6/28 was drawn up to define the project. It was conducted as a public/private joint venture, the Air Ministry funding it with £60,000 and Short Brothers providing the rest. The aircraft was originally designated the Short R6/28 before being named the Sarafand. Design The Sarafand was a six-engined biplane flying boat with equal span wings. Due to the high wing end loads, Gouge sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Singapore
The Short Singapore was a British multi-engined biplane flying boat built after the First World War. The design was developed into two four-engined versions: the prototype Singapore II and production Singapore III. The latter became the Royal Air Force's main long-range maritime patrol flying boat of the 1930s and saw service against the Japanese with the Royal New Zealand Air Force during the Second World War. Design and development The first prototype of the Short Singapore, also known as the Short S.5 ( military designation Singapore I), was a metal hull version of the wooden-hulled Short Cromarty. The biplane design included a single fin and rudder, and was originally powered by two Rolls-Royce Condor IIIA engines. Its maiden flight was made from Rochester on 17 August 1926, piloted by Short's Chief Test Pilot John Lankester Parker. The type did not enter production, but was used by Sir Alan Cobham for a survey flight around Africa. Registered ''G-EBUP'', it left Rochest ...

Boeing XPB
The Boeing XPB (company Model 50) was an American twin-engined biplane long-range patrol flying boat of the 1920s. A single example was built for the United States Navy. Design and development In September 1924, the Naval Aircraft Factory was tasked with designing a long-range twin-engined flying boat, capable of flying the 2,400 mi (3,860 km) between San Francisco and Hawaii. The initial design was carried out by Isaac Laddon, an employee of Consolidated Aircraft, and then passed to Boeing for detailed design and construction. The new flying boat, the Boeing Model 50, was a two-bay biplane of very streamlined design for flying boats of the time. The wings were of metal construction, with wooden wingtips and leading edges. The fuselage had a metal lower part, with the upper half made of laminated wooden frames with a wood veneer covering. Two 800 hp (600 kW) Packard 2A-2500 V12 engines driving four-bladed propellers were mounted in tandem between the win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Curtiss V-1570-54 Conqueror
The Curtiss V-1570 Conqueror was a 12-cylinder vee liquid-cooled aircraft engine. Representing a more powerful version of the Curtiss D-12, the engine entered production in 1926 and flew in numerous aircraft.Gunston 1989, p. 46. Design and development Designed in 1924 as a military successor to the Curtiss D-12, initially named the Conqueror, it was later given the military designation of V-1570 based on its displacement of 1,570 cubic inches (26 L). The engine featured open-ended cylinder liners (advanced technology for the period) and pressurized liquid cooling. Developments including the use of a supercharger gradually increased power output until reliability problems due to overheating and coolant leaks became apparent. Military funding for further development of the Conqueror was cut in 1932, efforts by Curtiss to market the engine for civil airliners failed and the line was dropped from production.
