Widerøe Polar
The Widerøe C.5 Polar, sometimes known as the Honningstad C.5 Polar, was a Norwegian general-purpose land or floatplane built by Widerøes Flyveselskap. Design and development The Norwegian airline Widerøe decided in the late 1940s to design and build a general-purpose aircraft for its own use. Built in the airline's workshops, the Widerøe C.5 Polar was a braced high-wing monoplane which could be operated on floats, skis, or wheels. It had an enclosed cabin for a pilot and up to five passengers, and the passenger seats were removable to enable the aircraft to be used for freight or as an air ambulance. The first C.5 Polar was built and flown in 1948. Operational history A small number of aircraft entered service with the Widerøes Flyveselskap airline.

Birger Hønningstad
Birger Hønningstad (17 September 1904 – 2 April 1976) was a Norwegians, Norwegian engineer and Aerospace engineering, aircraft designer. Biography Hønningstad was born in Ås, Akershus, Norway. He was the son of Amund Bertelsen Hønningstad (1875-1944) and Grethe Olsen Sagesund (1874-1953).He attended the Norwegian Institute of Technology in Trondheim with continued studies at the University of Detroit, graduating in 1931. In 1933, Hønningstad started his own engineering company in Oslo. From 1937, he was also a theoretical teacher at Viggo Widerøe, Viggo Widerøe Airline School at Bogstad. Hønningstad constructed several airplanes, first in his own engineering firm, Birger Hønningstad & Co, and after World War II at Norsk Flyindustri, where he was director and chairman. Hønningstad's initiative, together with shipowner Ole Bergesen (1891), Ole Bergesen, resulted in the establishment of an airport in the Stavanger area of Norway.

1948 In Aviation
This is a list of aviation-related events from 1948: Events * Publication of Nevil Shute's novel '' No Highway'' set in the world of research into aviation safety. * The United States Air Force has 20,800 aircraft, about half of them combat aircraft, down from 68,400 aircraft at the end of World War II in 1945. U.S. Air Force personnel strength stands at 387,000. * The United States inventory of atomic bombs reaches 50 weapons during the year. Each requires two days to assemble for use, and by mid-1948 the United States has only two bomb assembly teams. * Faced with deep disagreement within the United States Armed Forces over their appropriate roles in national defense, United States Secretary of Defense James V. Forrestal orders Chief of Staff of the United States Army General Omar N. Bradley, Chief of Naval Operations Louis E. Denfield, and Chief of Staff of the United States Air Force General Carl A. Spaatz to meet at Key West, Florida, in March and at Newport, Rhode Is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pratt & Whitney R-985
The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial engine, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a Engine displacement, displacement of ; initial versions produced , while the most widely used versions produce . Wasp Juniors have powered numerous smaller civil and military aircraft, including small transports, utility aircraft, trainers, agricultural aircraft, and helicopters. Over 39,000 engines were built, and many are still in service today. Design and development Pratt & Whitney developed the R-985 Wasp Junior as a smaller version of the Pratt & Whitney R-1340, R-1340 Wasp to compete in the market for medium-sized aircraft engines. Like its larger brother, the Wasp Junior was an air-cooled, nine-cylinder radial, with its power boosted by a gear-driven single-speed centrifugal type supercharger. Its cylinders were smaller, however, with a Bore (engine), bore an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

1940s Norwegian Civil Utility 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.

Floatplanes
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call floatplanes "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, has greatly reduced the number of flying boats being built. However, many modern civilian aircraft have floatplane variants, most offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found their niche as one type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
