A seaplane is a powered fixed-wing aircraft capable of taking off and landing alighting on water. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft , or amphibians. Seaplanes were sometimes called hydroplanes , [2] but currently this term applies instead to motor-powered watercraft that use the technique of hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war.
In the 21st century, seaplanes maintain a few niche uses, such as for dropping water on forest fires, air transport around archipelagos, and access to undeveloped or roadless areas, some of which have numerous lakes. The term "seaplane" is used by some instead of "floatplane".
This is the standard British usage. An amphibious aircraft can take off and land both on conventional runways and water. A true seaplane can only take off and land on water. There are amphibious flying boats and amphibious floatplanes, as well as some hybrid designs, e. Examples in between include the Dornier Seastar flying-boat type, seat, utility amphibian and the Canadair CL amphibious water-bomber. On 6 June , Gabriel Voisin took off and landed on the River Seine with a towed kite glider on floats.
The first of his unpowered flights was yards m. Other pioneers also attempted to attach floats to aircraft in Britain, Australia, France and the United States. On 28 March , Frenchman Henri Fabre flew the first successful powered seaplane, the Gnome Omega -powered hydravion , a trimaran floatplane. The first hydro-aeroplane competition was held in Monaco in March , featuring aircraft using floats from Fabre, Curtiss, Tellier and Farman. This led to the first scheduled seaplane passenger services, at Aix-les-Bains , using a five-seat Sanchez-Besa from 1 August On May 10, Glenn L.
Martin flew a homemade seaplane in California , setting records for distance and time. Its first successful flight was on 13 April Combining floats with wheels, he made the first amphibian flights in February and was awarded the first Collier Trophy for US flight achievement.
From , his experiments with a hulled seaplane resulted in the Model E and Model F , which he called "flying-boats". In Britain, Captain Edward Wakefield and Oscar Gnosspelius began to explore the feasibility of flight from water in They decided to make use of Windermere in the Lake District , England's largest lake. The latter's first attempts to fly attracted large crowds, though the aircraft failed to take off and required a re-design of the floats incorporating features of Borwick's successful speed-boat hulls.
Meanwhile, Wakefield ordered a floatplane similar to the design of the Fabre Hydravion. By November , both Gnosspelius and Wakefield had aircraft capable of flight from water and awaited suitable weather conditions. Gnosspelius's flight was short-lived, as the aircraft crashed into the lake.
Wakefield's pilot, however, taking advantage of a light northerly wind, successfully took off and flew at a height of 50 feet 15 m to Ferry Nab, where he made a wide turn and returned for a perfect landing on the lake's surface. A seaplane was used during the Balkan Wars in , when a Greek "Astra Hydravion" did a reconnaissance of the Turkish fleet and dropped four bombs.
American businessman Rodman Wanamaker became determined that the prize should go to an American aircraft and commissioned the Curtiss Aeroplane and Motor Company to design and build an aircraft capable of making the flight. Curtiss's development of the Flying Fish flying boat in brought him into contact with John Cyril Porte , a retired Royal Navy Lieutenant, aircraft designer and test pilot who was to become an influential British aviation pioneer.
Recognising that many of the early accidents were attributable to a poor understanding of handling while in contact with the water, the pair's efforts went into developing practical hull designs to make the transatlantic crossing possible.
Benoist , initiate the start of the first heavier-than-air airline service anywhere in the world, and the first airline service of any kind at all in the United States. At the same time, the British boat-building firm J. Samuel White of Cowes on the Isle of Wight set up a new aircraft division and produced a flying boat in the United Kingdom.
This was displayed at the London Air Show at Olympia in Saunders boatyard of East Cowes and the Sopwith Aviation Company produced the "Bat Boat", an aircraft with a consuta laminated hull that could operate from land or on water, which today is called an amphibious aircraft. Navy, which rapidly resulted in the America , designed under Porte's supervision following his study and rearrangement of the flight plan; the aircraft was a conventional biplane design with two-bay, unstaggered wings of unequal span with two pusher inline engines mounted side-by-side above the fuselage in the interplane gap.
Wingtip pontoons were attached directly below the lower wings near their tips. The design later developed into the Model H resembled Curtiss's earlier flying boats but was built considerably larger so it could carry enough fuel to cover 1, mi 1, km.
The three crew members were accommodated in a fully enclosed cabin. Trials of the America began 23 June with Porte also as Chief Test Pilot; testing soon revealed serious shortcomings in the design; it was under-powered, so the engines were replaced with more powerful tractor engines. There was also a tendency for the nose of the aircraft to try to submerge as engine power increased while taxiing on water. In order to counteract this effect, Curtiss fitted fins to the sides of the bow to add hydrodynamic lift, but soon replaced these with sponsons , a type of underwater pontoon mounted in pairs on either side of a hull.
These sponsons or their engineering equivalents and the flared, notched hull would remain a prominent feature of flying-boat hull design in the decades to follow. With the problem resolved, preparations for the crossing resumed.
While the craft was found to handle "heavily" on takeoff, and required rather longer take-off distances than expected, the full moon on 5 August was selected for the trans-Atlantic flight; Porte was to pilot the America with George Hallett as co-pilot and mechanic.
Curtiss and Porte's plans were interrupted by the outbreak of World War I. Appointed Squadron Commander of Royal Navy Air Station Hendon , he soon convinced the Admiralty of the potential of flying boats and was put in charge of the naval air station at Felixstowe in Porte persuaded the Admiralty to commandeer and later, purchase the America and a sister craft from Curtiss. This was followed by an order for 12 more similar aircraft, one Model H-2 and the remaining as Model H-4 's.
Four examples of the latter were assembled in the UK by Saunders. All of these were similar to the design of the America and, indeed, were all referred to as America s in Royal Navy service. The engines, however, were changed from the under-powered hp Curtiss engines to hp Rolls-Royce Falcon engines.
The initial batch was followed by an order for 50 more totalling 64 Americas overall during the war. The Curtiss H-4s were soon found to have a number of problems; they were underpowered, their hulls were too weak for sustained operations, and they had poor handling characteristics when afloat or taking off.
At Felixstowe, Porte made advances in flying-boat design and developed a practical hull design with the distinctive "Felixstowe notch". Porte modified an H-4 with a new hull whose improved hydrodynamic qualities made taxiing, take-off and landing much more practical and called it the Felixstowe F.
Porte's innovation of the "Felixstowe notch" enabled the craft to overcome suction from the water more quickly and break free for flight much more easily. This made operating the craft far safer and more reliable. The "notch" breakthrough would soon after evolve into a "step", with the rear section of the lower hull sharply recessed above the forward lower hull section, and that characteristic became a feature of both flying-boat hulls and seaplane floats.
The resulting aircraft would be large enough to carry sufficient fuel to fly long distances and could berth alongside ships to take on more fuel.
Porte then designed a similar hull for the larger Curtiss H flying boat which, while larger and more capable than the H-4s, shared failings of a weak hull and poor water handling. The combination of the new Porte-designed hull, this time fitted with two steps, with the wings of the H and a new tail, and powered by two Rolls-Royce Eagle engines, was named the Felixstowe F.
It was used as the basis for all future designs. Another seventy were built, and these were followed by two F. In February , the first prototype of the Felixstowe F. It was larger and heavier than the F. Approximately Felixstowe F. The Felixstowe F. The prototype showed superior qualities to its predecessors but, to ease production, the production version was modified to make extensive use of components from the F.
In , they were towed on lighters towards the northern German ports to extend their range; on 4 June , this resulted in three F. Curtiss, among others, also built the Felixstowe F. In Italy, several seaplanes were developed, starting with the L series and progressing with the M series.
The Macchi M. Two hundred forty-four were built in total. The German aircraft manufacturing company Hansa-Brandenburg built flying boats starting with the model Hansa-Brandenburg GW in , and had a degree of military success with their Hansa-Brandenburg W.
The Austro-Hungarian firm Lohner-Werke began building flying boats, starting with the Lohner E in and the later influential Lohner L version. In September , British company Supermarine started operating the first flying-boat service in the world, from Woolston to Le Havre in France , but it was short-lived. Of the four that made the attempt, only one completed the flight.
In , the first successful commercial flying-boat service was introduced, with flights to and from the Channel Islands. The British aviation industry was experiencing rapid growth. The Government decided that nationalization was necessary and ordered five aviation companies to merge to form the state-owned Imperial Airways of London IAL.
IAL became the international flag-carrying British airline, providing flying-boat passenger and mail-transport links between Britain and South Africa using aircraft such as the Short S. The flight was considered proof that flying boats had evolved to become a reliable means of long-distance transport. In the s, flying boats made it possible to have regular air transport between the U. Foynes , Ireland and Botwood , Newfoundland and Labrador were the termini for many early transatlantic flights.
In areas where there were no airfields for land-based aircraft, flying boats could stop at small island, river, lake or coastal stations to refuel and resupply. The Pan Am Boeing "Clipper" planes brought exotic destinations like the Far East within reach of air travelers and came to represent the romance of flight. In that year, government tenders on both sides of the world invited applications to run new passenger and mail services between the ends of the Empire, and Qantas and IAL were successful with a joint bid.
A company under combined ownership was then formed, Qantas Empire Airways. The new ten-day service between Rose Bay, New South Wales , near Sydney and Southampton was such a success with letter writers that before long, the volume of mail was exceeding aircraft storage space. A solution to the problem was found by the British government, who in , had requested aviation manufacturer Short Brothers to design a big new long-range monoplane for use by IAL.
Partner Qantas agreed to the initiative and undertook to purchase six of the new Short S23 C class, or Empire , flying boats.
Delivering the mail as quickly as possible generated a lot of competition and some innovative designs. One variant of the Short Empire flying boats was the strange-looking Maia and Mercury. It was a four-engined floatplane "Mercury" the winged messenger fixed on top of "Maia", a heavily modified Short Empire flying boat.
This allowed the Mercury to carry sufficient fuel for a direct trans-Atlantic flight with the mail.
