Flying Boat
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 the 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airline
An airline is a company that provides air transport services for traveling passengers and freight. Airlines use aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or charter operators. The first airline was the German airship company DELAG, founded on November 16, 1909. The four oldest non-airship airlines that still exist are the Netherlands' KLM (1919), Colombia's Avianca (1919), Australia's Qantas (1920) and the Czech Republic's Czech Airlines (1923). Airline ownership has seen a shift from mostly personal ownership until the 1930s to government-ownership of major airlines from the 1940s to 1980s and back to large-scale privatization following the mid-1980s. Since the 1980s, there has al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Kress
Wilhelm Kress (29 July 1836 in Saint Petersburg – 24 February 1913 in Vienna) Born of German (Bavarian) parents in St. Petersburg in 1836. Moved to Vienna in 1873, where his self-propelled flying models attracted much attention. He became a naturalized Austrian. Life Kress came to Vienna in 1873, where he developed the first modern delta-flying hang glider in 1877. This hang-glider was a major achievement for the time, when many engineers still struggled with the development of "heavier-than-air" non-powered aircraft. He also displayed rubber band powered flying models called the 'Aeroveloce' in 1877 and 1880. During the turn of the century he was one of the world-wide contestants for the creation of a break-through powered airplane. In 1900 he developed the control stick for aircraft, but did not apply for a patent (instead, a patent was awarded to the French aviator, Robert Esnault-Pelterie who applied for it in 1907). Kress' aircraft, the Drachenflieger, was constructe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alphonse Pénaud
Alphonse Pénaud (31 May 1850 – 22 October 1880), was a 19th-century French pioneer of aviation design and engineering. He was the originator of the use of twisted rubber to power model aircraft, and his 1871 model airplane, which he called the ''Planophore'', was the first aerodynamically stable flying model. He went on to design a full-sized aircraft with many advanced features, but was unable to get any support for the project, and eventually committed suicide in 1880, aged 30. Biography Pénaud was born in Paris into a naval family, his father Charles Pénaud being an admiral in the French Navy. Because of a hip disease he walked with the aid of crutches and so was unable to attend the Naval School. At 20, he began studying aviation and joined the newly-founded ''Société Aéronautique de France''. He became vice-president of the Society in 1876 and participated in the publication of the journal ''L'Aéronaute''. In 1870, Pénaud made the first of a series of succe ...

Martin JRM Mars
The Martin JRM Mars is a large, four-engined cargo transport flying boat designed and built by the Martin Company for the United States Navy during World War II. It was the largest Allied flying boat to enter production, although only seven were built. The United States Navy contracted the development of the XPB2M-1 Mars in 1938 as a long-range ocean patrol flying boat, which later entered production as the JRM Mars long-range transport. Four of the surviving aircraft were later converted for civilian use to firefighting water bombers. Two of the aircraft still remain based at Sproat Lake just outside of Port Alberni, British Columbia, although neither is operational. Design and development The Glenn L.

Shin Meiwa US-1A
The Shin Meiwa PS-1 and US-1A is a large STOL aircraft designed for anti-submarine warfare (ASW) and air-sea rescue (SAR) work respectively by Japanese aircraft manufacturer Shin Meiwa. The PS-1 anti-submarine warfare (ASW) variant is a flying boat which carried its own beaching gear on board, while the search-and-rescue (SAR) orientated US-1A is a true amphibian. Development of the PS-1 has its origins in flying boat research performed by the Shin Meiwa during the 1950s. The company, believing that their design was capable of regular use upon the open sea, petitioned the Japanese military to acquire the type as a maritime patrol aircraft (MPA). Following the demonstration of a converted Grumman HU-16 Albatross testbed aircraft, referred to as the UF-XS, the Japan Maritime Self-Defense Force (JMSDF) awarded Shin Meiwa a contract in 1966 to further develop its design via two further prototypes, which were designated PS-X. During 1969, the JMSDF placed the first order for an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Atlantic (1940)
The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943. The Battle of the Atlantic pitted U-boats and other warships of the German '' Kriegsmarine'' (Navy) and aircraft of the '' Luftwaffe'' (Air Force) against the Royal Navy, Royal Canadian Navy, United States Navy, and Allied merchant shipping. Convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces. These forces were aided by ships and aircraft of the United States beginning September 13, 1941. Carney, Robert B., Admiral, USN. "Comment and ...

Asiatic-Pacific Theater
The Asiatic-Pacific Theater was the theater of operations of U.S. forces during World War II in the Pacific War during 1941–1945. From mid-1942 until the end of the war in 1945, two U.S. operational commands were in the Pacific. The Pacific Ocean Areas (POA), divided into the Central Pacific Area, the North Pacific Area and the South Pacific Area, were commanded by Fleet Admiral Chester W. Nimitz, Commander-in-Chief Pacific Ocean Areas. The South West Pacific Area (SWPA) was commanded by General of the Army Douglas MacArthur, Supreme Allied Commander South West Pacific Area. During 1945, the United States added the United States Strategic Air Forces in the Pacific, commanded by General Carl A. Spaatz. Because of the complementary roles of the United States Army and the United States Navy in conducting war, the Pacific Theater had no single Allied or U.S. commander (comparable to General of the Army Dwight D. Eisenhower in the European Theater of Operations). No actual c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Sunderland
The Short S.25 Sunderland is a British flying boat patrol bomber, developed and constructed by Short Brothers for the Royal Air Force (RAF). The aircraft took its service name from the town (latterly, city) and port of Sunderland in North East England. Developed in parallel with the civilian S.23 ''Empire'' flying boat, the flagship of Imperial Airways, the Sunderland was developed specifically to conform to the requirements of British Air Ministry Specification R.2/33 for a long-range patrol/reconnaissance flying boat to serve with the Royal Air Force (RAF). As designed, it served as a successor to the earlier Short Sarafand flying boat. Sharing several similarities with the S.23, it featured a more advanced aerodynamic hull and was outfitted with various offensive and defensive armaments, including machine gun turrets, bombs, aerial mines, and depth charges. The Sunderland was powered by four Bristol Pegasus XVIII radial engines and was outfitted with various detec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
