Stipa-Caproni
The Stipa-Caproni, also known as the Caproni Stipa, was an experimental Italian aircraft designed in 1932 by Luigi Stipa (1900–1992) and built by Caproni. It featured a hollow, barrel-shaped fuselage with the engine and propeller completely enclosed by the fuselage—in essence, the whole fuselage was a single ducted fan. Although the ''Regia Aeronautica'' (Italian Royal Air Force) was not interested in pursuing development of the Stipa-Caproni, its design influenced the development of jet propulsion. Stipa's design Stipa’s basic idea, which he called the " intubed propeller", was to mount the engine and propeller inside a fuselage that itself formed a tapered duct, or venturi tube, and compressed the propeller's airflow and the engine exhaust before it exited the duct at the trailing edge of the aircraft, essentially applying Bernoulli's principle of fluid movements to make the aircraft's propeller more efficient. This is a similar principle as is used in turbofan engines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Luigi Stipa
Luigi Stipa (30 November 1900 – 9 January 1992) was an Italian aeronautical, hydraulic, and civil engineer and aircraft designer who invented the "intubed propeller" for aircraft, a concept that some aviation historians view as the predecessor of the turbofan engine. Early life and career Stipa was born in Appignano del Tronto, Italy in 30 November 1900. He left school to serve in the Italian Army's Bersaglieri Corps during World War I. After the war, he earned academic degrees in aeronautical engineering, hydraulic engineering and civil engineering. He went to work for the Italian Air Ministry, where he rose to the position of general inspector of the Engineering Division of the ''Regia Aeronautica'' (Italian Royal Air Force). Intubed propeller In the 1920s, Stipa applied his study of hydraulic engineering to develop a theory of how to make aircraft more efficient as they traveled through the air.

Caproni
Caproni, also known as ''Società de Agostini e Caproni'' and ''Società Caproni e Comitti'', was an Italian aircraft manufacturer. Its main base of operations was at Taliedo, near Linate Airport, on the outskirts of Milan. Founded by Giovanni Battista "Gianni" Caproni during 1908, the company produced several successful heavy bombers during the First World War. Following the acquisition of several other aviation firms throughout the interwar period, Caproni transformed into a sizable aviation-orientated syndicate, the ''Società Italiana Caproni, Milano''. The majority of its aircraft were bombers and transport aircraft. It played a pioneering role in the development of the Caproni Campini N.1, an experimental aircraft powered by a thermo-jet. It provided large numbers of combat aircraft for the Axis during the Second World War. The firm did not prosper in the postwar era, the Società Italiana Caproni collapsing during 1950.

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

De Havilland Gipsy III
The de Havilland Gipsy is a British air-cooled four-cylinder in-line aircraft engine designed by Frank Halford in 1927 to replace the ADC Cirrus in the de Havilland DH.60 Moth light biplane. Initially developed as an upright 5 litre (300 cubic inch) capacity engine, later versions were designed to run inverted with increased capacity and power. The Gipsy went on to become one of the most popular sport aircraft engines of the inter-war period and was the engine of choice for various other light aircraft, trainers, liaison aircraft and air taxis, British as well as foreign, until long past World War II. Apart from helping to establish the de Havilland Aircraft Company as a manufacturer of light aircraft, it also established the company as an engine manufacturer in its own right. Gipsy engines remain in service powering vintage light aircraft. Design and development Just like the ADC Cirrus, the Gipsy was born as a collaboration between aircraft manufacturer Geoffre ...

Nacelle
A nacelle ( ) is a "streamlined body, sized according to what it contains", such as an engine, fuel, or equipment on an aircraft. When attached by a pylon entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine. In some cases—for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning—an aircraft cockpit may also be housed in a nacelle, rather than in a conventional fuselage. Etymology Like many aviation terms, the word comes from French, in this case from a word for a small boat. Development The development of the Arado Ar 234, merging the four nacelles into two The Arado Ar 234 was one of the first operational jet aircraft with engines mounted in nacelles. During its development, the four jet engines were merged from having four distinct nacelles, all of which contained their own landing gear wheel, to two nacelles with two engi ...

Leesburg, Virginia
Leesburg is a town in the state of Virginia, and the county seat of Loudoun County. Settlement in the area began around 1740, which is named for the Lee family, early leaders of the town and ancestors of Robert E. Lee. Located in the far northeast of the state, in the War of 1812 it was a refuge for important federal documents evacuated from Washington, DC, and in the Civil War, it changed hands several times. Leesburg is west-northwest of Washington, D.C., along the base of Catoctin Mountain and close to the Potomac River. The town is the northwestern terminus of the Dulles Greenway, a private toll road that connects to the Dulles Toll Road at Washington Dulles International Airport. Its population was 48,250 as of the 2020 Census and an estimated 48,908 in 2021. It is Virginia's largest incorporated town within a county (rather than being an independent city). Leesburg, like much of Loudoun County, has undergone considerable growth and development over the last 30 years, tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
