Lascurain Aura
The Lascurain Aura was a prototype of a regional aircraft designed and built for Mexican engineer Angel Lascurain. It was the largest aircraft designed and built in Mexico. Development Lascurain wanted to manufacture an aircraft designed for the regional airlines of some parts of Mexico that required connecting populations in very rugged geographical areas that had no access to any other type of transport than the aerial and the rugged terrain caused the airstrips to be very short for the American and European aircraft of those times. Lascurain determined that regional airlines required a twin-engine plane with fixed landing gear that was accessible (since foreign aircraft cost more than one million pesos and airlines could not pay for them), capable of landing at low speed on short runways. The aircraft had to have a high rate of climb to overcome the mountainous areas. In 1955 Ángel Lascurain went with the architect Juan Cortina Portilla, beginning the design of the aircr ...

Wright R-760
The Wright R-760 Whirlwind was a series of seven-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of 756 in³ (12.4 L) and power ratings of 225-350 hp (168-261 kW). Design and development Wright introduced the J-6 Whirlwind family in 1928 to replace the nine-cylinder R-790 series. The J-6 family included varieties with five, seven, and nine cylinders. The seven-cylinder version was originally known as the J-6 Whirlwind Seven, or J-6-7 for short. The U.S. government designated it as the R-760; Wright later adopted this and dropped the J-6 nomenclature. Like all the members of the J-6 Whirlwind family, the R-760 had larger cylinders than the R-790. The piston stroke of 5.5 in (14.0 cm) was unchanged, but the cylinder bore was expanded to 5.0 in (12.7 cm) from the R-790's bore of 4.5 in (11.4 cm). While the R-790 was naturally aspirated, the ...

Armstrong Siddeley Cheetah
The Armstrong Siddeley Cheetah is a seven-cylinder British air-cooled aircraft radial engine of 834 cu in (13.65 L) capacity introduced in 1935 and produced until 1948. Early variants of the Cheetah were initially known as the Lynx Major.Lumsden 2003, p.74. The Cheetah was used to power many British trainer aircraft during World War II including the Avro Anson and Airspeed Oxford. Design and development The Cheetah was developed from the earlier Lynx using the increased bore cylinders from the Armstrong Siddeley Panther but the engine retained the stroke of the Lynx. Initially only direct-drive variants were produced with later engines being made available with propeller reduction gear of various ratios. Superchargers were also available for later variants, both geared and directly driven by the crankshaft. The basic design of the Cheetah remained unchanged from its introduction in 1935 to the last examples built in 1948. It was the first engine of its type to be certified ...

Octane Rating
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress the fue ...

House Of Whitley
A house is a single-unit residential building. It may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems.Schoenauer, Norbert (2000). ''6,000 Years of Housing'' (rev. ed.) (New York: W.W. Norton & Company). Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arkansas Air Museum
The Arkansas Air & Military Museum is an aviation and military museum located at Drake Field in Fayetteville, Arkansas. It is the largest aviation museum in Arkansas. History The museum was originally established in 1986 as the Arkansas Air Museum. In 2012, it merged with the Ozark Military Museum housed next door into the Arkansas Air & Military Museum. In 2014, its board of directors noted that a decrease in visitors had resulted in the museum struggling to stay financially viable: that year, its monthly profits were roughly $5,000, compared to monthly expenses of around $7,000. Also in 2014, the museum only had one paid employee, with the remainder of its personnel consisting entirely of volunteers. According to board member Russell Smith, the museum's number of annual visitors shrunk from approximately 26,000 to 6,000 after the opening of Interstate 540 and Northwest Arkansas Regional Airport replaced Drake Field as the region's principal airport in 1998.

Waco CG-15
The Waco CG-15 was an American military glider, which was developed from the CG-4. Although outwardly similar to its predecessor and carrying the same number of passengers, a number of changes in the design, including shortened wings and a more streamlined nose enabled it to travel faster. 1,000 were ordered and 473 were delivered before production ceased. Two were transferred to the Navy for testing as the XLR2W-1. One unit was converted into an XPG-3 powered glider which used two Jacobs R-755-9 radial engines.

Waco Standard Cabin Series
The Waco Standard Cabin series is a range of American single-engine 4–5 seat fabric covered cabin biplanes produced by the Waco Aircraft Company beginning in 1931 with the QDC and continuing until 1942 when production ended for the VKS-7F.Brandley, 1981, p.76 They were used as light passenger and utility transports, navigational trainers, bushplanes and briefly as maritime reconnaissance aircraft during World War 2. Design All of the Waco Standard Cabins were powered by cowled radial engines and Waco tried to accommodate their customers preferences for many of the more common commercially available engines of the period, hence the profusion of designations, as the first letter indicates the engine installed. Individual models were each certified with various available engines but not all variations found customers. Fuselage structure was typical for the period, being welded chrome-moly tubing with light wood strips to fair the shape in and covered with fabric.Juptner, 1962, pp ...
