Lockheed Big Dipper
The Lockheed Model 34 Big Dipper was an American two-seat monoplane, designed and built by Lockheed at Burbank for research into the company's potential entry into the civil lightplane and military light utility aircraft market. Only one was built, and following its loss in an accident the program was abandoned. Design and development Developed by John Thorp and based on his work on Lockheed's Little Dipper lightplane project,Francillon 1982, pp. 277 the Lockheed Model 34, named "Big Dipper", was intended as a prototype for a lightplane to sell on the postwar market - Lockheed hoping to sell the aircraft at a price of $1500 - and as a potential 'flying jeep' for the United States Army. It was a low-wing cantilever monoplane with a fixed tricycle landing gear and a conventional empennage; the cabin was enclosed, seating two in side-by-side positions. Unusually the Continental C100 piston engine was fitted in the center fuselage behind the cabin, driving a two-bladed pusher propell ...

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 ...

1940s United States Civil Utility Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Ryan Navion
The Ryan (originally North American) Navion is a single-engine, unpressurized, retractable gear, four-seat aircraft originally designed and built by North American Aviation in the 1940s. It was later built by Ryan Aeronautical Company and the Tubular Steel Corporation (TUSCO). The Navion was envisioned as an aircraft that would perfectly match the expected postwar boom in civilian aviation, since it was designed along the general lines of, and by the same company which produced the North American P-51 Mustang. Design and development The Navion was originally designed at the end of World War II by North American Aviation as the NA-143 (but produced under the NA-145 designation).Taylor, Michael, J.H., ed.

Globe Swift
The Globe GC-1 Swift, also known as the Globe/Temco Swift, is a light, two-seat sport monoplane from the post-World War II period. Design and development The Swift was designed by R.S. "Pop" Johnson in 1940, despite the fanciful story which has now entered into popular mythology surrounding the Swift's origin (that a Culver Cadet was obtained as a "template" aircraft). The design was financially secured by John Kennedy, president of the Globe Medicine Company, to be built by his new Globe Aircraft Company. World War II interrupted their plans, however, and the GC-1A Swift advertised as the "All Metal Swift" re-designed by K.H."Bud" Knox, received its type certificate on 7 May 1946. Two prototypes were built but essentially, the design remained the same as the type entered production. Globe built about 408 GC-1As. Later that year, the Swift received a more powerful engine of , making it the GC-1B. Globe, together with TEMCO, built 833 GC-1Bs in six months. Globe's producti ...

ERCO Ercoupe
The ERCO Ercoupe is an American low-wing monoplane aircraft that was first flown in 1937. It was originally manufactured by the Engineering and Research Corporation (ERCO) shortly before World War II; several other manufacturers continued its production after the war. The final model, the Mooney M-10, first flew in 1968 and the last model year was 1970. It was designed to be the safest fixed-wing aircraft that aerospace engineering could provide at the time, and the type continues to enjoy a faithful following. Design and development Fred Weick In 1931, aeronautical engineer Fred Weick was assistant chief of the aeronautics division of the National Advisory Committee for Aeronautics (NACA). In 1934 he asked permission to build an aircraft based on the 1931 Stout Skycar, using fabric instead of aluminum covering, and control modifications based on NACA research. Weick and a group of co-workers designed and assembled the experimental aircraft with a group of his colleagues wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas Cloudster II
The Douglas Cloudster II was an American prototype five-seat light aircraft of the late 1940s. It was of unusual layout, with two buried piston engines driving a single pusher propeller. Only a single example was built, which flew only twice, as it proved too expensive to be commercially viable. Design and development During the early 1940s, Douglas Aircraft Company developed a configuration for high-performance twin-engined aircraft, in which the engines were buried in the fuselage, driving propellers mounted behind a conventional tailplane, in order to reduce drag by eliminating drag inducing objects such as engines from the wing. This layout was first demonstrated in the Douglas XB-42 Mixmaster bomber, which first flew in 1944, showing a 30% reduction in drag compared with a conventional twin-engined layout, while eliminating handling problems due to asymmetric thrust when flying on one engine.Francillon 1979, pp. 372–377. Owing to the initial success of the XB-42, Dougla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 engi ...
