Dornier Do 212
The Dornier Do 212 was a four-seat experimental amphibian flying boat built by the Swiss subsidiary of Dornier, in Altenrhein on Lake Constance. Design was initiated in 1938 by the German and Swiss branches, the latter being responsible for the actual construction of the prototype. The Do 212 was an all-metal cantilever monoplane with fixed wingtip floats and a 343 kW (460 hp) Hirth HM 512-B-0 12-cylinder air-cooled engine which, mounted aft of the cabin, was buried in the fuselage The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section.

Flying Boat
A flying boat is a type of seaplane with a hull, allowing it to land on water. It differs from a floatplane in having a fuselage that is purpose-designed for flotation, while floatplanes rely on fuselage-mounted floats for buoyancy. Though a flying boat’s fuselage provides buoyancy, it may also utilize under-wing floats or wing-like hull projections (called sponsons) for additional stability. 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 20th century, exceeded in size only by bombers developed during the Second World War. Their advantage lay in using water instead of expensive land-based runways, making them the basis for international airlines in the interwar period. They were also commonly used as maritime patrol aircraft and air-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuselage
The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds Aircrew, crew, passengers, or cargo. In single-engine aircraft, it will usually contain an Aircraft engine, engine as well, although in some amphibious aircraft the single engine is mounted on a hardpoint, pylon attached to the fuselage, which in turn is used as a floating Hull (watercraft), hull. The fuselage also serves to position the Flight control surfaces, control and Stabilizer (aeronautics), stabilization surfaces in specific relationships to Wing, lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welding, welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight strin ...

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple wings. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower an ...

Mid-engined Aircraft
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive comp ...

1940s German Experimental Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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. Events By place Roman Empire * Decimus Clodius Septimius Albinus Caesar became a Roman Consul. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Escher-Wyss
Escher Wyss & Cie., also known as Escher Wyss AG, was a Swiss industrial company focused on engineering and turbine construction. Its headquarters were in the Zürich quarter of Escher Wyss, which takes its name from the company. History The company was founded, as Escher Wyss & Cie., in 1805 by Hans Caspar Escher and Salomon von Wyss. After having originally started the company as a textile spinning business, the two expanded their enterprise to include a machine shop that manufactured textile machinery, water wheels, water turbines, power transmission equipment, and starting in 1835, ships, including boilers and steam engines. After 1860, under the direction of Hans Zoelly, the company concentrated on hydraulic systems, steam engines and cooling systems. Between 1904 and 1929 steam turbines were produced for thermal power plants, ships and locomotives. The company also manufactured hydraulic systems for hydroelectric plants. Around this time it provided equipment for Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hirth HM 512B-0
The Hirth HM 512 was a 12-cylinder development of the earlier, 6-cylinder HM 506, produced in the late 1930s. Both were supercharged, inverted V, air-cooled engines. Design and development The HM 512 shared the same bore and stroke (105 mm × 115 mm) and 6:1 compression ratio with the rest of the HM500 series air-cooled engines. Other shared features were Hirth's use of roller bearings in the crankshaft and at both ends of connecting rods. The crankshaft was of typical Hirth multipart design, the 12-cylinders requiring 7 roller bearings. Like the HM 508, the drive was geared down by 1:1.5. Variants ;HM 512A:Initial version; take off power 400 hp (300 kW), continuous 360 hp (270 kW) ;HM 512B:Take off power 450 hp (335 kW), continuous 360 hp (270 kW) Applications * Dornier Do 212 The Dornier Do 212 was a four-seat experimental amphibian flying boat built by the Swiss subsidiary of Dornier, in Altenrhein on Lake Constance.

Dornier Do 24
The Dornier Do 24 is a 1930s German three-engine flying boat designed by the Dornier Flugzeugwerke for maritime patrol and search and rescue. A total of 279 were built among several factories from 1937 to 1945. Design and development The Dornier Do 24 was designed to meet a Royal Netherlands Navy requirement for a replacement of the Dornier Do J, Dornier Wals being used by its Netherlands Naval Aviation Service, Naval Aviation Service in the Dutch East Indies, with the Netherlands government signing a contract for six Dornier Do 24s on 3 August 1936. Two more prototypes were built for the German navy to be evaluated against the Blohm & Voss BV 138.Green and Swanborough ''Air Enthusiast'' April–July 1983, pp. 9–10. The Do 24 was an all-metal Parasol wing, parasol monoplane with a broad-beamed Hull (watercraft), hull and stabilising sponsons. Twin tails were mounted on the upswept rear of the hull, while three wing-mounted tractor configuration engines powered the aircraft. F ...

Aircraft Cabin
An aircraft cabin is the section of an aircraft in which passengers travel. Most modern commercial aircraft are pressurized, as cruising altitudes are high enough such that the surrounding atmosphere is too thin for passengers and crew to breathe. In commercial air travel, particularly in airliners, cabins may be divided into several parts. These can include travel class sections in medium and large aircraft, areas for flight attendants, the galley, and storage for in-flight service. Seats are mostly arranged in rows and aisles. The higher the travel class, the more space is provided. Cabins of the different travel classes are often divided by curtains, sometimes called class dividers. Passengers are not usually allowed to visit higher travel class cabins in commercial flights. Some aircraft cabins contain passenger entertainment systems. Short and medium haul cabins tend to have no or shared screens whereas long and ultra-long haul flights often contain personal screens. E ...
