Dewoitine D.26
The Dewoitine D.26 was a military trainer developed in Switzerland for the Swiss Air Force in parallel with the D.27 fighter. Design and development The D.26 airframe was similar to that of the D.27. Differences included: *The engine cowling was omitted on the D.26; *The D.26 radial engine was smaller and produced 340 hp power; Operational history 10 examples were built by Dewoitine for assembly by the Swiss factory K+W Thun in Switzerland. These were followed by an order for two more aircraft equipped with a slightly higher-powered version of the Wright 9Q engine that powered the initial batch, and one of the original D.26s was similarly re-engined. The original D.26s were used principally for training in gunnery and formation flying, while the more powerful aircraft were used for air-to-air combat training. To this end, they were equipped with gun cameras. The D.26 enjoyed a long service life, not being withdrawn until 1948. At this time, they were transferred to the ...

Wright Whirlwind
The Wright Whirlwind was a family of air-cooled radial aircraft engines built by Wright Aeronautical (originally an independent company, later a division of Curtiss-Wright). The family began with nine-cylinder engines, and later expanded to include five-cylinder and seven-cylinder varieties. Fourteen-cylinder twin-row versions were also developed, but these were not commercially produced. The Whirlwind series was succeeded by more powerful but still air-cooled radial aero engines, notably the Pratt & Whitney Wasp series and the Wright Cyclone series. Description The Whirlwind was a direct descendant of the Lawrance J-1, a nine-cylinder air-cooled radial built by the Lawrance Aero Engine Company for the U.S. Navy. Because the Navy was very enthusiastic about air-cooled radials, but was concerned that Lawrance could not produce enough engines for its needs, it forced Wright to purchase the Lawrance company in 1923 and build the J-1 itself. Wright's J-1 was the first engine in it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasol-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 planes. 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 a ...

Dewoitine Aircraft
Constructions Aéronautiques Émile Dewoitine was a French aircraft manufacturer established by Émile Dewoitine at Toulouse in October 1920. The company's initial products were a range of metal parasol-wing fighters which were largely ignored by the French Air Force but purchased in large quantities abroad and licence-built in Italy, Switzerland, and Czechoslovakia. The company was liquidated in January 1927, with the only remaining active programme (the D.27) being transferred to EKW in Switzerland. The company was re-established in Paris in March the following year as Société Aéronautique Française (Avions Dewoitine) or SAF. After briefly continuing D.27 production, the reconstituted firm produced a range of fighters that became a mainstay of the French airforce during the 1930s, the D.500 family. It also developed important civilian airliners, such as the D.333 and its derivative the D.338, designed for pioneering routes to French Indochina (Vietnam), and eventually Ho ...

Wright R-975 Whirlwind
The Wright R-975 Whirlwind was a series of nine-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of about and power ratings of . They were the largest members of the Wright Whirlwind engine family to be produced commercially, and they were also the most numerous. During World War II, Continental Motors built the R-975 under license as a powerplant for Allied tanks and other armored vehicles. Tens of thousands of engines were built for this purpose, dwarfing the R-975's usage in aircraft, where it was overshadowed by the similar Pratt & Whitney R-985. After the war, Continental continued to produce its own versions of the R-975 into the 1950s. Some of these produced as much as . The R-975 powered the American World War II M18 Hellcat tank destroyer which was claimed to have been the fastest tracked armored vehicle until the introduction of the turbine powered M1 Abrams in the 1980s.

Military Glider
Military gliders (an offshoot of common gliders) have been used by the militaries of various countries for carrying troops ( glider infantry) and heavy equipment to a combat zone, mainly during the Second World War. These engineless aircraft were towed into the air and most of the way to their target by military transport planes, e.g., C-47 Skytrain or Dakota, or bombers relegated to secondary activities, e.g., Short Stirling. Most military gliders do not soar, although there were attempts to build military sailplanes as well, such as the DFS 228. Once released from the tow craft near the front, they were to land on any convenient open terrain close to the target, hopefully with as little damage to the cargo and crew as possible as most landing zones (LZ) were far from ideal. The one-way nature of the missions meant that they were treated as semi-expendable leading to construction from common and inexpensive materials such as wood. Most nations seriously attempted to recover as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gun Camera
Gun cameras are cameras mounted on a gun, used to photograph or record from its perspective. They are typically used on the weapons of military aircraft and operate either when the gun is fired or at the operator's will. Gun cameras are used for training, analysis, or documentation purposes. History The use of gun cameras first became common for gunnery training in the 1920s, though examples were used during World War I by the British Royal Flying Corps. A special version of the Lewis gun, the Hythe Mark III, was manufactured as a camera gun for the Royal Flying Corps, used by trainees in lieu of actual Lewis guns during mock combat exercises. During World War II gun cameras were commonly used on operational aircraft to record kills of enemy aircraft. Many photographs and videos from gun cameras, including those filmed by USAAF flying ace Lieutenant Colonel Jack T. Bradley, survive to this day and are often used as stock footage. In 2017, a Zeiss nose-mounted gun camera u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Training
Flight training is a course of study used when learning to pilot an aircraft. The overall purpose of primary and intermediate flight training is the acquisition and honing of basic airmanship skills. Flight training can be conducted under a structured accredited syllabus with a flight instructor at a flight school or as private lessons with no syllabus with a flight instructor as long as all experience requirements for the desired pilot certificate/license are met. Typically flight training consists of a combination of two parts: * ''Flight Lessons'' given in the aircraft or in a certified Flight Training Device . * ''Ground School'' primarily given as a classroom lecture or lesson by a flight instructor where aeronautical theory is learned in preparation for the student's written, oral, and flight pilot certification/licensing examinations. Although there are various types of aircraft, many of the principles of piloting them have common techniques, especially those aircraf ...
