Beechcraft XT-36
The Beechcraft XT-36 (company designation Model 46, intended production designation T-36A) was an American twin-engine trainer-transport aircraft project of the early 1950s by the Beech Aircraft Company. The project was initiated by the United States Air Force on an expedited basis to address expected wartime aircrew training needs, but changing requirements led to delays, design difficulties, and spiraling development costs. The aircraft was ultimately deemed unnecessary and canceled before the prototypes flew. Design and development The project was started in 1951 with the rising demand for new aircrew due to the Korean War. The XT-36 was intended for use in both trainer and transport roles, but the United States Air Force (USAF) initiated the project primarily to address an anticipated shortage of North American TB-25 trainers. The USAF wanted to eventually use turboprop power but no suitable engine could be identified when the requests for proposals were issued; the direct ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister 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'' 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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Pressurized Cabin
Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for passengers and crew flying at high altitudes. For aircraft, this air is usually bled off from the gas turbine engines at the compressor stage, and for spacecraft, it is carried in high-pressure, often cryogenic, tanks. The air is cooled, humidified, and mixed with recirculated air if necessary before it is distributed to the cabin by one or more environmental control systems. The cabin pressure is regulated by the outflow valve. While the first experimental pressurization systems saw use during the 1920s and 1930s, it was not until 1940 that a commercial aircraft would enter service with a pressurized cabin, when the Boeing 307 Stratoliner joined the Transcontinental & Western Air and Pan American Airways fleets. The practice would become widespread a decade later, particularly with the introduction of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadair Aircraft
Canadair Ltd. was a civil and military aircraft manufacturer in Canada. In 1986, its assets were acquired by Bombardier Aerospace, the aviation division of Canadian transport conglomerate Bombardier Inc. Canadair's origins lie in the establishment of a factory for Canadian Vickers in the Saint-Laurent borough of Montreal, at Cartierville Airport. It was created as a separate entity by the government of Canada on 11 November, 1944. Throughout much of its existence, it was a subsidiary of various other aircraft manufacturers prior to being nationalized by the Canadian government in 1976. For a decade, the company operated as a federally-owned Crown Corporation. In 1986, Canadair was privatized via its sale to Bombardier, after which it became a core element of the firm's aerospace division. The company's former principal manufacturing facility, ''Canadair Plant One'', remains intact to the present day, although Cartierville Airport itself has been closed and since undergone r ...

T-29 Flying Classroom
The Convair C-131 Samaritan is an American twin-engined military transport produced from 1954 to 1956 by Convair. It is the military version of the Convair CV-240 family of airliners.Gradidge 1997, p. 20–21. Design and development The design began life in a production requirement by American Airlines for a pressurized airliner to replace the Douglas DC-3. Convair's original design had two engines and 40 seats, and thus it was designated the ''CV-240''. The first CV-240 flew on March 16, 1947, and production aircraft were first delivered to American on February 28, 1948. Seventy-five were delivered to American, with another fifty going to Western Airlines, Continental Airlines, Pan American Airways, KLM, Sabena, Swissair and Trans Australia Airlines. Operational history The CV-240/340/440 series was used by the United States Air Force (USAF) for medical evacuation and VIP transport and was designated as C-131 Samaritan.

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized 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 around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...
