CTA Convertiplano
The Convertiplano is a cancelled Brazilian convertiplane project. It is based on the earlier Focke-Achgelis Fa 269. Henrich Focke revived the design in the early 1950s on behalf of Brazil's Centro Técnico Aeroespacial (CTA), at the time the air force's technical center, who had contracted him to develop a convertiplane. The Convertiplano was built using the fuselage and wings of a Supermarine Spitfire Mk.XIV, serial RM874, acquired by the Brazilian Air Attaché's office in Brazil. Britain refused to supply the Armstrong Siddeley Double Mamba engine originally selected and the design was altered to accept a mid-mounted Wright R-3350 Duplex-Cyclone The Wright R-3350 Duplex-Cyclone is an American twin-row, supercharged, air-cooled, radial aircraft engine with 18 cylinders displacing nearly .

Lockheed Constellation
The Lockheed Constellation ("Connie") is a propeller-driven, four-engined airliner built by Lockheed Corporation starting in 1943. The Constellation series was the first pressurized-cabin civil airliner series to go into widespread use. Its pressurized cabin enabled commercial passengers to fly well above most bad weather for the first time, thus significantly improving the general safety and ease of air travel. Several different models of the Constellation series were produced, although they all featured the distinctive triple-tail and dolphin-shaped fuselage. Most were powered by four 18-cylinder Wright R-3350 Duplex-Cyclones. In total, 856 were produced between 1943 and 1958 at Lockheed's plant in Burbank, California, and used as both a civil airliner and as a military and civilian cargo transport. Among their famous uses was during the Berlin and the Biafran airlifts. Three served as the presidential aircraft for Dwight D. Eisenhower, one of which is featured at the Nat ...

Mid-engined Aircraft
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive com ...

Aircraft Manufactured In Brazil
An 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 by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. 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, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air bal ...

Tiltrotor Aircraft
A tiltrotor is an aircraft which generates lift and propulsion by way of one or more powered rotors (sometimes called ''proprotors'') mounted on rotating shafts or nacelles usually at the ends of a fixed wing. Almost all tiltrotors use a transverse rotor design, with a few exceptions that use other multirotor layouts. Tiltrotor design combines the VTOL capability of a helicopter with the speed and range of a conventional fixed-wing aircraft. For vertical flight, the rotors are angled so the plane of rotation is horizontal, generating lift the way a normal helicopter rotor does. As the aircraft gains speed, the rotors are progressively tilted forward, with the plane of rotation eventually becoming vertical. In this mode the rotors provide thrust as a propeller, and the airfoil of the fixed wings takes over providing the lift via the forward motion of the entire aircraft. Since the rotors can be configured to be more efficient for propulsion (e.g. with root-tip twi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1950s Brazilian Experimental Aircraft
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Focke-Achgelis Aircraft
Focke-Achgelis & Co. G.m.b.H. was a German helicopter company founded in 1937 by Henrich Focke and Gerd Achgelis. History Henrich Focke was ousted in 1936 from the Focke-Wulf company, which he had cofounded in 1924, due to shareholder pressure. There is reason to believe that Focke's removal was to allow Focke-Wulf's manufacturing capacity to be used to produce Bf 109 aircraft. The company was taken over by AEG, but soon after this the Air Ministry, which had been impressed by the Focke-Wulf Fw 61 helicopter, suggested that Focke establish a new company dedicated to helicopter development, and issued him with a requirement for an improved design, capable of carrying a payload. Focke established the Focke-Achgelis company at Hoykenkamp, Germany, on 27 April 1937, in partnership with pilot Gerd Achgelis, and began development work at Delmenhorst in 1938.

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 ...

Henrich Focke
Henrich Focke (8 October 1890 – 25 February 1979) was a German aviation pioneer from Bremen and also a co-founder of the Focke-Wulf company. He is best known as the inventor of the Fw 61, the first successful German helicopter. Biography Early life Henrich Focke was born in Bremen on 8 October 1890, Focke studied at Leibniz University Hannover, where he became friends with Georg Wulf in 1911. In 1914, he and Wulf both reported for military service and Focke was deferred due to heart problems, but was eventually drafted into an infantry regiment. After serving on the Eastern front, he was transferred to the Imperial German Army Air Service. Focke graduated in 1920 as Dipl-Ing with distinction. His first job was with the Francke Company of Bremen as a designer of water-gas systems. Focke-Wulf and Focke-Achgelis In 1923, with Wulf and Dr. Werner Naumann, Focke co-founded Focke-Wulf-Flugzeugbau GmbH. In 1927 Wulf died while test flying the Focke-Wulf F 19 canard mon ...

Wright R-3350 Duplex-Cyclone
The Wright R-3350 Duplex-Cyclone is an American twin-row, supercharged, air-cooled, radial aircraft engine with 18 cylinders displacing nearly . Power ranged from 2,200 to over 3,700 hp (1,640 to 2,760 kW), depending on the model. Developed before World War II, the R-3350's design required a long time to mature before finally being used to power the Boeing B-29 Superfortress. After the war, the engine had matured sufficiently to become a major civilian airliner design, notably in its turbo-compound forms, and was used in the Lockheed L-1049 Super Constellation airliners into the 1990s. The engine is commonly used on Hawker Sea Fury and Grumman F8F Bearcat Unlimited Class Racers at the Reno Air Races. Its main rival was the , Pratt & Whitney R-4360 Wasp Major, first run some seven years after the Duplex-Cyclone's beginnings. Design and development In 1927, Wright Aeronautical introduced its famous "Cyclone" engine, which powered a number of designs in the 1930s. ...
