Spartan Aircraft Company
The Spartan Aircraft Company was an American aircraft manufacturing company, headquartered on Sheridan Avenue near the Tulsa Municipal Airport in Tulsa, Oklahoma. Previously known as Mid-Continent Aircraft Company, the company had been reorganized under the Spartan name in 1928 by oil baron William G. Skelly—and operated until 1961, manufacturing aircraft, aircraft components, and Travel trailer, recreational vehicle trailers. The company was known for the luxurious Spartan Executive aircraft produced in the late 1930s and early 1940s. J. Paul Getty acquired the company from Skelly in 1935. After World War II, Getty ended aircraft production and converted the company to manufacturing trailers under the Spartan Manor brand—subsequently ending all production in 1961.Tolman, Keith.

Flight School
Flight training is a course of study used when learning to aviator, pilot an aircraft. The overall purpose of primary and intermediate flight training is the acquisition and honing of basic airmanship skills. Flight training can be conducted under a structured accredited syllabus with a flight instructor at a flight school or as private lessons with no syllabus with a flight instructor as long as all experience requirements for the desired pilot certificate/license are met. Typically flight training consists of a combination of two parts: * ''Flight Lessons'' given in the aircraft or in a certified Flight simulator#Types of flight training devices in service, Flight Training Device. * ''Ground School'' primarily given as a classroom lecture or lesson by a flight instructor where aeronautical theory is learned in preparation for the student's written, oral, and flight pilot certification/licensing examinations. Although there are various types of aircraft, many of the principle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Ceiling
With respect to aircraft performance, a ceiling is the maximum density altitude an aircraft can reach under a set of conditions, as determined by its flight envelope. Service ceiling Service ceiling is the density altitude at which the rate of climb drops below a prescribed value. The service ceiling is the maximum altitude of an aircraft during normal operations. Specifically, it is the density altitude at which flying in a clean configuration, at the best rate of climb airspeed for that altitude and with all engines operating and producing maximum continuous power, will produce a given rate of climb. A typical value might be climb, or on the order of climb for jet aircraft. The one-engine inoperative (OEI) service ceiling of a twin-engine, fixed-wing aircraft is the density altitude at which flying in a clean configuration, at the best rate of climb airspeed for that altitude with one engine producing maximum continuous power and the other engine shut down (and if it has ...

Aerodynamic
Aerodynamics () is the study of the motion of atmosphere of Earth, air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier-than-air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer si ...

Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of whi ...

Pratt & Whitney Wasp Jr
The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a displacement of ; initial versions produced , while the most widely used versions produce . Wasp Juniors have powered numerous smaller civil and military aircraft, including small transports, utility aircraft, trainers, agricultural aircraft, and helicopters. Over 39,000 engines were built, and many are still in service today. Design and development Pratt & Whitney developed the R-985 Wasp Junior as a smaller version of the R-1340 Wasp to compete in the market for medium-sized aircraft engines. Like its larger brother, the Wasp Junior was an air-cooled, nine-cylinder radial, with its power boosted by a gear-driven single-speed centrifugal type supercharger. Its cylinders were smaller, however, with a bore and stroke of , giving a 27% lesser total displacement. The Wasp Junior use ...

Spartan Executive 7 (NC17633) Arrives RIAT Fairford 10thJuly2014 Arp
Sparta was a prominent city-state in Laconia in ancient Greece. In antiquity, the city-state was known as Lacedaemon (), while the name Sparta referred to its main settlement in the Evrotas Valley, valley of Evrotas (river), Evrotas river in Laconia, in southeastern Peloponnese. Around 650 BC, it rose to become the dominant military land-power in ancient Greece. Sparta was recognized as the leading force of the unified Greek military during the Greco-Persian Wars, in rivalry with the rising naval power of Classical Athens, Athens. Sparta was the principal enemy of History of Athens, Athens during the Peloponnesian War (431–404 BC), from which it emerged victorious after the Battle of Aegospotami. The decisive Battle of Leuctra against Thebes, Greece, Thebes in 371 BC ended the Spartan hegemony, although the city-state maintained its Independence, political independence until its forced integration into the Achaean League in 192 BC. The city nevertheless recovered m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spartan C2-165
The Spartan C2 is a light aircraft produced in the United States in the early 1930s as a low-cost sport machine that would sell during the Great Depression. Design and development The C2 is a conventional, low-wing monoplane design with two seats side-by-side in an open cockpit.''The Illustrated Encyclopedia of Aircraft'', p.2955Taylor 1989, p.835 The wing was braced with struts and wires and it carried the main units of the divided fixed undercarriage. Power was supplied by a small radial engine mounted tractor-fashion in the nose, which drove a two-bladed propeller. Spartan introduced the C2 in 1931 with a 55-hp engine, and sold 16 examples before ongoing economic circumstances brought production to a halt. Spartan then built 2 examples with 165-hp engines to use in their own flying school. These latter aircraft were fitted with hoods that could be closed over the cockpit for training pilots in instrument flying."C2-60, -165", ''Aerofiles''"Spartan's Aircraft Manufacturing Hist ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market. Development history * 1903: Manly-Balzer engine sets standards for later radial engines. * 1910: Coandă-1910, an unsuccessful ducted fan aircraft exhibited at Paris Aero Salon, powered by a piston engine. The aircraft never flew, but a patent was filed for routing exhaust gases into the duct to augment thrust. * 1914: Auguste Rateau suggests using exhaust-powered compressor – a turbocharger – to improve high-altitude performance; not accepted after the ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about , and the metric horsepower as in "cv" or "PS" which is approximately . The electric horsepower "hpE" is exactly , while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other power-generating machinery such as piston engines, turbines, and electric motors. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power.
