Árnason JFP-2S-8
The Árnason JFP-2S-8 was a 1990s Icelandic experimental aircraft that utilised jet flap technology. It did not fly. Design and development Kristján Árnason was an aircraft engineer who designed and built the JFP-2S-8 to incorporate a 'jet flap propulsion' system he had devised and for which he had been granted a WIPO patent. The aeroplane was a high-wing monoplane, of canard configuration. Two intakes, positioned midway along the fuselage, fed air to two high-pressure turbines, powered by a pair of two-stroke engines. The compressed air was then expelled out over full-span flaps that formed the trailing edges of both the forewing and the main wing. The aeroplane featured a fully faired fuselage, an enclosed cockpit, a central tailfin, and a fixed tricycle undercarriage. Design commenced in 1975, construction started circa 1987 and was completed in 1996. Both the aircraft's model name and its registration of TP-JFP reference its 'jet flap propulsion' system.

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Ball-Bartoe Jetwing
__NOTOC__ The Ball-Bartoe JW-1 Jetwing was a US research aircraft flown in the 1970s to investigate blown wing technology. Design and development The Jetwing was a small, mid-wing design powered by a turbofan and fitted with tail-wheel undercarriage. The upper surface of the swept wings incorporated a slot along 70% span, through which air from the engine's fan stage could be discharged. Mounted above this slot was a small secondary airfoil called an "augmentor", intended to direct the discharged airflow over the wing. With this arrangement, it was found that the aircraft remained controllable at airspeeds as low as . The US Navy considered developing the Jetwing for use on short aircraft carriers. A new series of test flights were then carried out. Despite its top speed of 350 mph, the Navy was able to land the Jetwing in a mere 300 feet. Ultimately, the Navy discontinued blown-wing research in favor of vectored thrust technology.https://airfactsjournal.com/2021/02/from-j ...

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 ...

Canard Aircraft
In aeronautics, a canard is a wing configuration in which a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft or a weapon. The term "canard" may be used to describe the aircraft itself, the wing configuration, or the foreplane.Clancy, L. J. (1975). ''Aerodynamics'', Pitman (UK), Halsted (US), 1975. Pages 292-3.. Canard wings are also extensively used in guided missiles and smart bombs. The term "canard" arose from the appearance of the Santos-Dumont 14-bis of 1906, which was said to be reminiscent of a duck (''canard'' in French) with its neck stretched out in flight. Despite the use of a canard surface on the first powered aeroplane, the Wright Flyer of 1903, canard designs were not built in quantity until the appearance of the Saab Viggen jet fighter in 1967. The aerodynamics of the canard configuration are complex and require careful analysis. Rather than use the conventional tailplane configuration found on most aircraft, an aircraf ...

Aircraft With Fixed Tricycle Landing Gear
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windstar YF-80
The Windstar YF-80 is an American single-seat homebuilt replica of the Lockheed F-80. Design and development The YF-80 is a two-thirds scale replica of a Lockheed F-80 or T-33. The aircraft is a composite-construction, single-engine, low-wing design, with retractable tricycle landing gear. The tip tanks are removable for aerobatic flight. The aircraft is powered by a Chevy 350 V-8 turbocharged engine driving a turbine thrust section. The thrust section is driven by belts with high gear ratios to drive the turbine closer to the rotational speed it was originally designed for. The aircraft project was intended to showcase the Davis engine technology, with a static prototype displayed in 1977. Burt Rutan was approached to build the composite fuselage, but the US$240,000 cost estimate was declined. Davis attempted to produce a production prototype fuselage for US$80,000. By 1987, the project was not complete, resulting in a court case between investors. The prototype was re-engined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunting H
Hunting is the Human activity, human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products (fur/hide (skin), hide, bone/tusks, horn (anatomy), horn/antler, etc.), for recreation/taxidermy (see trophy hunting), although it may also be done for resourceful reasons such as removing predators dangerous to humans or domestic animals (e.g. wolf hunting), to pest control, eliminate pest (organism), pests and nuisance animals that damage crops/livestock/poultry or zoonosis, spread diseases (see varmint hunting, varminting), for trade/tourism (see safari), or for conservation biology, ecological conservation against overpopulation and invasive species (commonly called a culling#Wildlife, cull). Recreationally hunted species are generally referred to as the ''game (food), game'', and are usually mammals and birds. A person participating in a hunt is a ...
