Saunders A.14
The Saunders A.14 was a test aircraft for Saunders' new metal hull construction method, being a Supermarine Southampton fitted with the Saunders' fuselage. The methods tested worked well enough to be used in SARO flying boat production from 1928 to 1938. Development After the disappointing failure of the Valkyrie to gain orders, it was evident that Saunders' traditional wooden hulled flying boats were out of date. The Saunders A.14, sometimes known as the "Metal Hull", was a one-off aircraft to test Saunders' innovative metal hull design. This hull construction was used on all the Saunders and Saunders-Roe flying boats designed up to about 1935: the A.7, Cutty Sark, Cloud, Windhover and London. To avoid the effort of designing a complete aircraft to test their new hull design Saunders were awarded a joint contract with Supermarine to fit a standard Supermarine Southampton Mk. II with a Saunders hull. Thus, exactly as the Southampton, the A.14 was a large twin engined, tri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease.

Alclad
Alclad is a corrosion-resistant aluminium sheet formed from high-purity aluminium surface layers metallurgically bonded (rolled onto) to high-strength aluminium alloy core material. It has a melting point of about 500 degrees celsius, or 932 degrees Fahrenheit. Alclad is a trademark of Alcoa but the term is also used generically. Since the late 1920s, Alclad has been produced as an aviation-grade material, being first used by the sector in the construction of the ZMC-2 airship. The material has significantly more resistance to corrosion than most aluminium-based alloys, for only a modest increase in weight, making Alclad attractive for building various elements of aircraft, such as the fuselage, structural members, skin, and cowling. Accordingly, it became a relatively popular material for aircraft manufacturing. Details The material was described in NACA-TN-259 of August 1927, as "a new corrosion resistant aluminium product which is markedly superior to the present strong alloys ...

Aircraft First Flown In 1928
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

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] |

Vickers Valentia
The Vickers Valentia was a 1920s British flying boat designed during the First World War. History Three Valentia prototypes were built by the Vickers Company at their Barrow works (Walney Island perhaps), having been ordered in May 1918 as a potential replacement for the Felixstowe F.5. The hull was built by S.E.Saunders works at Cowes. The first of the three (Serial Number N124) first flew on 5 March 1921, when Stanley Cockerell began test-flying it over the Solent. N124 was damaged on landing in June 1921 and was dismantled, the second N125 forced landed on its delivery flight on 15 March 1922Wixey, Ken, "''Flying Boats of the RAF: 1920s 'One-offs' ''", FlyPast No. 106, Stamford, Lincs., U.K., May 1990, page 68. The third flying boat N126 was delivered in 1923 and used for trials until it was withdrawn from use in November 1924. The name was later re-used for a transport aircraft, the Vickers Type 264 Valentia The Vickers Valentia (company designation Type 264) was a ...

Saro Severn
The Saunders Severn was a three-engined biplane flying boat intended for maritime patrol duties. It performed well but was fragile and unreliable. Only one was built. Design and development The Saunders A.7 Severn was the last flying boat designed by S.E. Saunders Ltd before the takeover by A.V. Roe and John Lord late in 1928 that produced the Saunders-Roe, or "Saro", company. Its first flight was two years after this change of ownership and it has been alternatively referred to as the Saunders/Saro Severn, the Saunders-Roe A7 and the Saro A7. It was designed to Air Ministry specification R.4/27 for a maritime patrol aircraft. It was the second Saunders aircraft to use their patented "corrugated" structure for the hull, first trialled on the Saunders A.14, in which longitudinal external corrugations in the skin replaced internal riveted stringers. Full trials of the A.14, revealing both the strengths and weaknesses of this technique were not made until after the Severn h ...

Napier Lion
The Napier Lion is a 12-cylinder, petrol-fueled 'broad arrow' W12 configuration aircraft engine built by D. Napier & Son from 1917 until the 1930s. A number of advanced features made it the most powerful engine of its day and kept it in production long after other contemporary designs had been superseded. It is particularly well known for its use in a number of racing designs, for aircraft, boats and cars. Design and development Early in the First World War, Napier were contracted to build aero engines to designs from other companies, initially a Royal Aircraft Factory model and then Sunbeams. Both engines proved to be unreliable and in 1916 Napier decided to design an engine with high power, light weight and low frontal area. Napier's engineers laid out the engine with its 12 cylinders in what they called a "broad arrow"—three banks of four cylinders sharing a common crankcase. This suggested the design's first name, the Triple-Four. The configuration is also known as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Aircraft Experimental Establishment
The Marine Aircraft Experimental Establishment (MAEE) was a British military research and test organisation. It was originally formed as the Marine Aircraft Experimental Station in October 1918 at RAF Isle of Grain, a former Royal Naval Air Service seaplane base, to design, test and evaluate seaplanes, flying boats and other aircraft with a naval connection. It was renamed as the Marine and Armament Experimental Establishment on 16 March 1920 to recognise that weapons and other equipment were evaluated as well as complete aircraft. It was renamed again on 1 March 1924 as the Marine Aircraft Experimental Establishment. Relocations On 16 June 1924 the Establishment moved to the site of the former Seaplane Experimental Station seaplane base at Felixstowe. It carried out research and development work on water-based aircraft for service needs and also on their equipment and on air-sea rescue apparatus. The Establishment's work grew during its early years and by 1930 it was carrying o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duralumin
Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a trade name for one of the earliest types of age-hardenable aluminium alloys. The term is a combination of '' Dürener'' and ''aluminium''. Its use as a trade name is obsolete. Today the term mainly refers to aluminium–copper alloys, designated as the 2000 series by the international alloy designation system (IADS), as with 2014 and 2024 alloys used in airframe fabrication. History Duralumin was developed by the German metallurgist Alfred Wilm at Dürener Metallwerke AG. In 1903, Wilm discovered that after quenching, an aluminium alloy containing 4% copper would harden when left at room temperature for several days. Further improvements led to the introduction of duralumin in 1909. The name is mainly used in pop-science to describe all Al-Cu alloys system, or '2000' series, as designated through the international alloy designation system originally created in 1970 by the Aluminum A ...
