Galeão 8 FG Guanabara
The Galeão 8 FG Guanabara, was a Brazilian low-wing, single-engined experimental airplane intend to be an executive aircraft to the Brazilian Air Force.Taylor 1965, p. 12Pereira 1997, p. 171 Design and development The Guanabara was based on the Fokker S.12 training aircraft, then manufactured at Fokker's factory in Brazil. It was proposed by technicians from the Ministry of Aeronautics. The main differences were the little retractable landing gear, newly designed canopy cabin, and additional fuel tanks at the wingtips.Taylor 1965, p. 12 The prototype was ready in April 1965, and flight testing began shortly thereafter. It proved to be very interesting, but problems included the limited passenger capacity and the complicated forward-proof contraction mechanism. This problem made engine maintenance more complicated. The prototype was abandoned, and sent to São José dos Campos, and stored at Department of Aerospace Science and Technology The Brazilian Department of Science and ...

Wing Root
The wing root is the part of the wing on a fixed-wing aircraft or winged-spaceship that is closest to the fuselage,Peppler, I.L.: ''From The Ground Up'', page 9. Aviation Publishers Co. Limited, Ottawa Ontario, Twenty Seventh Revised Edition, 1996. and is the junction of the wing with the fuselage (not with a nacelle or any other body). The term is also used for the junction of the wing with the opposite wing, ie on the fuselage centerline, as with the upper wing of a biplane. The opposite end of a wing from the wing root is the wing tip. The aerodynamic properties of the overall aircraft can be greatly impacted by the shaping and other design choices of the wing root. During both normal flight and landings, the wing root of an aircraft would be typically subjected to the highest bending forces through the aircraft. As a means of reducing interference drag between the wing and the fuselage, the use of fairings (often referred to as "wing fillets") became commonplace during th ...

Jane's All The World's Aircraft
''Jane's All the World's Aircraft'' (now stylized Janes) is an aviation annual publication founded by John Frederick Thomas Jane in 1909. Long issued by Sampson Low, Marston in Britain (with various publishers in the U.S.), it has been published by Janes Information Services since 1989/90. The first volume's title referred to "airships" while all since have referenced "aircraft". After World War I, the format of the book shifted from an oblong ("landscape") format to the present "portrait" orientation. With the 1993/94 edition, the book was divided into two volumes that continue to appear annually. The main volume focuses on aircraft in production while the second book describes older aircraft and upgrades, both military and civil. While 2009 was the centennial year of ''Jane's All the World's Aircraft'', 2013 marked the 100th edition—the disparity due to disruptions (chiefly with volumes covering two years) during the two World Wars. Starting in 1969, Arco (New York) issued the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Niess 2-100
__NOTOC__ The Niess 2-100, was a civilian two-seat high-wing sport aircraft built in Brazil during 1952. Design and development It was developed and manufactured by Marc Niess, a Brazilian aeronautical engineer, while the certification tests for the Niess 1-80 were still underway. With a similar fuselage to its predecessor, it was distinguished by its tricycle landing gear and its negative-glare wings with forward-facing tips, which gave it advantages over stall. After some tests at the Parque Aeronáutico de São Paulo, some stability problems were noted, which were solved by increasing the rudder's vertical surface. Operational history The first prototype was sent to the Department of Aerospace Science and Technology in São José dos Campos, where it underwent further tests with pilots from the Brazilian Air Force, where it was approved. The National Civil Aviation Agency of Brazil bought two airplanes, including the prototype. The first ( PT-GLI) was deactivated after flyin ...

Weber W-151
__NOTOC__ The Weber W-151 was a light aircraft built by the Brazilian manufacturer Campanhia Nacional de Aviões. Development Willibald Weber began work on the W-151 in 1962, which flew for the first time in November 1962. The original plan was to build three prototypes. Although the aircraft was superior compared to the Cessna aircraft, series production was not started for cost reasons. The W-151 was a strutted shoulder-wing aircraft with conventional tailplane and non-retractable nose wheel landing gear Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Marti .... The aircraft was powered by a Continental IO-520C with 210 kW and was made entirely of metal. The enclosed cabin for up to six people could be entered through a door on the left side.

Neiva Universal
The Neiva N621 Universal is a Brazilian propeller-driven basic trainer and ground attack aircraft manufactured by Indústria Aeronáutica Neiva. It is a cantilever, low-wing monoplane of all-metal construction, with retractable undercarriage and side-by-side seating. Design and development The Universal was designed in 1963 as a new primary trainer for the Brazilian Air Force, as a replacement for the T-6 Texan and Fokker S-11/S-12 types then in use. The prototype (Registration PP-ZTW) first flew on 29 April 1966. The Brazilian Air Force ordered 150 aircraft as the T-25 Universal, and increased this order in 1978 by an additional 28 aircraft. A further developed version (designated the YT-25B Universal II) first flew on 22 October 1978 but was not put into production. The Universal was also adopted as a counter-insurgency aircraft. It was later replaced by the Tucano in both the advanced training and attack roles, but it is still used as a primary and basic trainer at the ...

Neiva Regente
Neiva Regente is a Brazilian propeller-driven four-seat light utility aircraft manufactured by Indústria Aeronáutica Neiva. History The design was started in 1959 for a four-seat cabin monoplane aircraft with a high wing and fixed undercarriage. The prototype, designated the Neiva Regente 360C, was first flown on 7 September 1961 with a 145 hp (108 kW) Continental O-300 piston engine. The type was ordered into production by the Brazilian Air Force with a more powerful 180 hp (134 kW) Lycoming O-360-A1D engine. Eighty aircraft were built originally designated the U-42 (later changed to C-42) for the utility role. First delivery occurred in February 1975.Mondey, David ''Encyclopedia of The World's Commercial and Private Aircraft'' Crescent Books, New York (1981) p. 205 Neiva developed a three-seat Air Observation Post version for the Air Force, designated the Regente 420L.

Variable-pitch
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. A controllable pitch propeller (CPP) can be efficient for the full range of rotational speeds and load conditions, since its pitch will be varied to absorb the maximum power that the engine is capable of producing. When fully loaded, a vessel will need more propulsion power than when empty. By varying the propeller blades to the optimal pitch, higher efficiency can be obtained, thus saving fuel. A vessel with a VPP can accelerate faster from a standstill and can decelerate much more effectively, making stopping quicker and safer. A CPP can also improve vessel maneuverability by directing a stronger flow of water onto the ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hartzell Propeller
Hartzell Propeller is an American manufacturer that was founded in 1917 by Robert N. Hartzell as the Hartzell Walnut Propeller Company. It produces composite and aluminum propellers for certified, homebuilt, and ultralight aircraft. The company is headquartered in Piqua, Ohio.Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook'', page 84. BAI Communications. Hartzell also produces spinners, governors, ice protection systems, and other propeller controls. History Robert Hartzell grew up in the village of Oakwood, Ohio, just a block from Hawthorn Hill, where Orville Wright lived. From the 1890s until the late 1910s, Hartzell's father and grandfather operated a sawmill and lumber supply company in Greenville, Ohio (later moved to Piqua, Ohio) that also manufactured items such as wagons and gun stocks for World War I. On the side, Robert owned a small airplane and did maintenance on it as a young man. In 1917, Orville Wright suggested that Hartzell use his walnut ...

Air-cooled
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a h ...

Flat Engine
A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber. The most common configuration of flat engines is the boxer engine configuration, in which the pistons of each opposed pair of cylinders move inwards and outwards at the same time. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks; in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in cars than straight engines (for engines with less than six cylinders) and V engines (for engin ...
