Allenbaugh Grey Ghost
The Grey Ghost was a high-speed experimental monoplane built by Ed Allenbaugh, and intended to compete in the 1948 Goodyear Trophy. Design and development The Grey Ghost was a shoulder-wing single-engine pusher monoplane, designed by Paul Schaupp and constructed by Ed Allenbaugh. It was notable for its small frontal area, with the fuselage measuring just wide and deep. The wings were cantilevered and had a tapered planform, with no dihedral. The pilot, positioned ahead of the wing, lay in an almost fully supine position. A centrally located Continental C85 engine powered, via an extension-shaft, a two-bladed fixed-pitch propeller that was positioned just aft of the empennage. The aircraft had a conventional tailplane, but an inverted tailfin that ensured that the propeller had sufficient ground clearance. It was equipped with a conventional fixed undercarriage. The aircraft was painted white, with the race number 66 and the registration mark N23C being painted in red. Op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoulder-wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple wings. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower an ...

Lesher Teal
The Lesher Teal is a home built experimental aircraft that at one point held seven Federation Aeronautique Internationale (FAI) class is C-l.a records for speed and distance. Design and development The Teal was designed to beat the Federation Aeronautique Internationale (FAI) class is C-l.a records for speed and distance. Construction started in 1962. The aircraft was configured as an all-aluminum single-place aircraft with retractable landing gear, powered by a 100 hp Continental O-200 engine driving a 64-inch Hartzell ground-adjustable propeller. By 28 April 1965, the airframe was complete. On that day, Lesher made the aircraft's first flight at Willow Run Airport. That August, he flew Teal to the 1965 EAA Fly-In in Rockford, Illinois, where he won an award from the EAA for his achievements. Operational history After two years of testing the Teal, Lesher flew the aircraft, on 22 May 1967, to a new 500 km closed-course Class C1a speed record of 181.55 mph. ...

Pusher Aircraft
In aeronautical and naval engineering, pusher configuration is the term used to describe a drivetrain of Aircraft, air- or watercraft with propulsion device(s) after the engine(s). This is in contrast to the more conventional tractor configuration, which places them in front. Though the term is most commonly applied to aircraft, its most ubiquitous propeller example is a common outboard motor for a small boat. “Pusher configuration” describes the specific (propeller or ducted fan) thrust device attached to a craft, either aerostat, aerostats (airship) or Heavier-than-air aircraft, aerodynes (aircraft, Ground effect vehicle, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboat, airboats, and propeller-driven snowmobiles. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplanes) were "pushers", including the Wright Flye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft With Fixed Conventional Landing Gear
An aircraft ( 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 the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." 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, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1940s United States Experimental Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday 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 * Decimus Clodius Septimius Albinus Caesar became a Roman Consul. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

PAR Special
The PAR Special was a high-speed experimental monoplane built by a consortium of aviation engineers, and competed in air races in the early 1950s. Design and development The Special was a project of four St. Louis-based McDonnell Aircraft employees; Arthur Beckington, George Owl, Errol Painter, and Robert Short. They formed a partnership called Parks Alumni Racebuilders, or PAR, named as a tribute to the Parks Air College that all four had graduated from. The Special was a shoulder-wing single-engine pusher monoplane, of wood and metal construction. It incorporated a variable-incidence wing, with a jackscrew A jackscrew, or screw jack, is a type of jack that is operated by turning a leadscrew. It is commonly used to lift moderate and heavy weights, such as vehicles; to raise and lower the horizontal stabilizers of aircraft; and as adjustable suppor ... mechanism allowing the wing to be adjusted in flight, with the angle of incidence covering the range from 0.5 through ...

Lesher Nomad
The Lesher Nomad is an innovative two-place homebuilt aircraft. Design and development Designer Edgar J Lesher had previously worked at Stinson Aircraft Company in Wayne, Michigan on the Stinson 106 Skycoach. The Skycoach was a four-place aircraft with a pusher propeller, a configuration which captured Lesher's imagination. In August 1958, he attended one of the early Experimental Aircraft Association Fly-Ins. The homebuilt aircraft he saw there inspired him to design one himself. Remembering the Skycoach, he began the design of an all-aluminum two-place, side-by-side, pusher propeller aircraft. Construction began in February 1959. In October 1961, after 5,000 hours of construction, he first flew his aircraft, the Lesher Nomad (N1066Z) at Willow Run Airport in Ypsilanti, Michigan. A novel design feature was his use of a Dodge Flexidyne Coupling in the drive train to dampen torsional vibrations. The aircraft was powered by a 100 hp Continental O-200 engine driving a 7 ...

Flat-four
A flat-four engine, also known as a horizontally opposed-four engine or boxer engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than a straight-four engine. There is a minor, secondary unbalanced rotational torque pulse in the plane of the pistons, when a piston pair at one end of the engine is at TDC and the other pair at BDC. The TDC pair creates a torque greater than the BDC pair, so the net unbalanced torque pulse is the difference. The difference in TDC vs BDC inertial forces is explained in the Engine balance section. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
