Lycoming O-435
The Lycoming O-435 is an American six-cylinder, horizontally opposed fixed-wing aircraft and helicopter engine made by Lycoming Engines. The engine is a six-cylinder version of the four-cylinder Lycoming O-290. Design and development The powerplant is a horizontally opposed Lycoming six-cylinder design. It is a direct-drive or geared, air-cooled, and normally aspirated engine. The cylinders have steel barrels with aluminum heads, and the valves are operated by hydraulic lifters. The crankshaft is supported in an aluminum-alloy split case by four main bearings and one ball-thrust bearing, and lubricating oil is supplied from a 12 quart wet sump. The camshaft rides in journals that do not employ bearing inserts. The accessory housing supports two magnetos, a starter, a generator, and a dual tach drive. A spare mounting pad is included for a vacuum pump. Variants All engines have an additional prefix preceding the ''435'' to indicate the specific configuration of the engine. Ther ...

Ignition Magneto
An ignition magneto, or high-tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. The older term ''tension'' means ''voltage''. The use of ignition magnetos is now confined mainly to engines where there is no other available electrical supply, for example in lawnmowers and chainsaws. It is also widely used in aviation piston engines even though an electrical supply is usually available. In this case, the magneto's self-powered operation is considered to offer increased reliability; in theory, the magneto should continue operation as long as the engine is turning. History Firing the gap of a spark plug, particularly in the combustion chamber of a high-compression engine, requires a greater voltage (or ''higher tension'') than can be achieved by a simple magneto. The ''high-tension magneto'' combines an alternating current magneto generator a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fokker F
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912. World War I Fokker capitalized o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fleetwings BQ-2
The Fleetwings BQ-2 was an early expendable unmanned aerial vehicle — referred to at the time as an " assault drone" — developed by Fleetwings during the Second World War for use by the United States Army Air Forces. Only a single example of the type was built; the aircraft was deemed too expensive for service and was cancelled after a brief flight testing career. Development Development of the BQ-2 began on July 10, 1942, under a program for the development of "aerial torpedoes" – unmanned flying bombs – that had been instigated in March of that year. Fleetwings was contracted to build a single XBQ-2 assault drone,Werrell 1985, p.30. powered by two Lycoming XO-435 horizontally opposed piston engines, and fitted with a fixed landing gear in tricycle configuration; the landing gear was jettisonable for better aerodynamics. The BQ-2 was optionally piloted; a single-seat cockpit was installed for ferry and training flights; a fairing would replace the cockpit canopy on op ...

D'Apuzzo Senior Aero Sport
__NOTOC__ The Parsons-Jocelyn PJ-260 was an aerobatic biplane aircraft built in the United States to participate in the 1962 World Aerobatic Championships in Budapest. It served as the prototype for a family of closely related aircraft produced under designer Nick D'Apuzzo's name as the D-260 and D-295 Senior Aero Sport', D-200 Junior Aero Sport and the D-201 Sportwing which were marketed for homebuilding. The original PJ-260 was named for the pilots who commissioned the aircraft and hoped to compete with it, Lindsey Parsons and Rod Jocelyn. The PJ-260 and its derivatives were conventional short-coupled biplanes with fixed tailwheel undercarriage. The single-bay, equal-span wings (unequal-span on D-295) were staggered and braced with N-struts, and the outer panels of the upper wing were swept back. The fuselage construction was of fabric over a steel-tube framework, and the wings were of fabric-covered wooden spars and metal ribs. Variants ;PJ-260 ;D-295 Senior Aero Sport: A ...

Bellanca Cruisemaster
The Bellanca 14-13 Cruisair Senior and its successors were a family of light aircraft that were manufactured in the United States by AviaBellanca Aircraft after World War II. They were a follow-up to the prewar Bellanca 14-7 and its derivatives. Design and development The 14-13 retained the Bellanca 14-7's basic design, but featured a redesigned fuselage structure which included an enlarged cabin, a horizontally opposed Franklin 6A4-335-B3 engine in place of the earlier models' various 70 hp to 120 hp engines, and an oval vertical endplate on each horizontal stabiliser. This latter feature gained the type the affectionate nickname "cardboard Constellation", because the arrangement was similar to the contemporary Lockheed Constellation airliner. ''1978 Aircraft Directory'' 1977, p. 20. Taking its numbering convention from the Bellanca tradition of identifying the series from the wing area in square feet, dropping the final digit, while the second number was the aircraft's ...

Bell H-13 Sioux
The Bell H-13 Sioux is an American single-engine light helicopter built by Bell Helicopter and manufactured by Westland Aircraft under license for the British military as the Sioux AH.1 and HT.2. Development In 1947, the United States Army Air Forces (later the United States Air Force) ordered the improved Bell Model 47A. Most were designated ''YR-13'' and three winterized versions were designated ''YR-13A''. The United States Army first ordered Bell 47s in 1948 under the designation ''H-13''. These would later receive the name ''Sioux''. Initially, the United States Navy procured several Bell 47s, designated ''HTL-1'', between 1947 and 1958. The United States Coast Guard evaluated this model, and procured two HTL-1s for multi-mission support in the New York Harbor. The most common U.S. Navy version of the 47 was designated the ''HTL-4'', and dispenses with the fabric covering on the tail boom. The U.S. Coast Guard procured three ''HTL-5''s in 1952 (similar to the HTL-4 but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AISA I-115
The AISA I-115 is a low-wing single-engined military primary trainer with tandem seating, which went into service with the Spanish Air Force in 1956. After retirement in 1976 many were sold to civil operators. Development The AISA I-115 was a military development of the single-engined civil side-by-side seat I-11 which first flew in 1951. This aircraft was designed by Iberavia but built by AISA; later, Iberavia were taken over by AISA. The I-115 inherited the tail wheel undercarriage of the production version of the I-11, the I-11B, but was a longer machine because the Spanish Air Force wanted tandem seating for its trainers, had a slightly greater span and was considerably heavier. These changes called for more power, so the I-115 used a 112 kW (150 hp) ENMA Tigre inverted in-line engine. Like the I-11 the I-115 had an all wood structure and most surfaces were plywood covered apart from fabric covered ailerons and flaps. The low, tapered, straight edged and squar ...

Aero Commander 500
The Aero Commander 500 family is a series of light-twin piston-engined and turboprop aircraft originally built by the Aero Design and Engineering Company in the late 1940s, renamed the Aero Commander company in 1950, and a division of Rockwell International from 1965. The initial production version was the 200-mph, seven-seat Aero Commander 520. An improved version, the 500S, manufactured after 1967, is known as the Shrike Commander. Larger variants are known by numerous model names and designations, ranging up to the 330-mph, 11-seat Model 695B/Jetprop 1000B turboprop. Design and development The idea for the Commander light business twin was conceived by Ted Smith, a project engineer at the Douglas Aircraft Company. Working part-time after hours throughout 1944, a group of A-20 engineers formed the Aero Design and Engineering Company to design and build the proposed aircraft with a layout similar to their A-20 bomber. Originally, the new company was going to build three pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
