Jurca MJ-54 Silas
The Jurca MJ-54 Silas is a two-seat light touring cargo aircraft designed by Marcel Jurca to enable a small car to be transported along with the pilot and passenger. Origins The aircraft came from an idea by Arthur-Joseph Torossian in 1992, who wanted a touring aircraft which could carry a very small vehicle, such as the Aixam Microcar, for use at remote airfields, and which could also be used as sleeping accommodation with the car removed. The car could also act as an aircraft tug at airports. He envisioned it as a combination of a Max Holste Broussard and a Transall C.160. He saw many other uses for the aircraft, including as an air ambulance, carrier for four parachutists, disabled persons carrier, or freighter. Torossian envisaged a market for 1000 aircraft, and during the development of the prototype was looking for a company to mass-produce it. In 2000 he was awarded the French Union of Inventors' prize for the best invention. Development The well-known designer of wooden h ...

Cockpit
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a Pilot in command, pilot controls the aircraft. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11 attacks, September 11, 2001 attacks, all major airlines Airport_security_repercussions_due_to_the_September_11_attacks#Improved_security_on_aircraft, fortified their cockpits against access by aircraft hijacking, hijackers. Etymology The word cockpit seems to have been cockpit (sailing), used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore.

Lycoming Engines
Lycoming Engines is a major American manufacturer of aircraft engines. With a factory in Williamsport, Pennsylvania, Lycoming produces a line of horizontally opposed, air-cooled, four, six and eight-cylinder engines including the only FAA-certified aerobatic and helicopter piston engines on the market. The company has built more than 325,000 piston aircraft engines and powers more than half the world's general aviation fleet, both rotary and fixed wing. Lycoming is an operating division of Avco Corporation, itself a subsidiary of Textron. History Sewing machines, bicycles and fashion Lycoming dates its founding to 1845 by " Madame Ellen Curtis Demorest". However, the early history of the company (especially prior to 1860) is unclear; biographer Ishbel Ross notes that the marriage of Ellen Louise Curtis to William Jennings Demorest took place in 1858, somewhat later than the purported date of establishment of the company. A few years later in New York, between c. 1860 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricycle Undercarriage
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172.

Tailplane
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In t ...

Centre Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a dis ...

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gull-wing Doors
In the automotive industry, a gull-wing door, also known as a falcon-wing door or an up-door, is a car door that is hinged at the roof rather than the side, as pioneered by Mercedes-Benz 300 SL, first as a race car in 1952 ( W194), and then as a production sports car in 1954. Opening upwards, the doors evoke the image of a seagull's wings. In French, they are (butterfly doors). The papillon door was designed by Jean Bugatti for the 1939 Type 64, 14 years before Mercedes-Benz produced its similar, famous 300 SL gullwing door. The papillon door is a precursor to the gullwing door, and is slightly different in its architecture, but is often overlooked when discussing gull-wing design. Conventional car doors are typically hinged at the front-facing edge of the door, with the door swinging outward horizontally. Apart from the Mercedes-Benz 300 SL of the mid-1950s, Mercedes-Benz SLS and the experimental Mercedes-Benz C111 of the early 1970s, the best-known examples of road-ca ...

Marcel Jurca
Marcel Jurca, (1921 – 19 October 2001) was a prolific designer of homebuilt aircraft in France. He is most well known for his Tempête and Sirocco designs. Early life Born in Romania, Jurca was impressed by the PZL fighters which often flew over him. He learned to fly in a Grunau 9 primary glider while studying engineering. Having joined the Royal Romanian Air Force in 1940, he flew the Henschel Hs 129 in 1943-1944. He moved to France in 1948. After a period as a volunteer flying instructor on the Stampe et Vertongen SV.4, he worked in industry, including 15 years as a commercial director, and retired in 1983. He was naturalised French in 1965. Aircraft design On moving to France, he missed having an aircraft to fly, so he created his own. His first attempt at aircraft design was the MJ-1, which he considered unsatisfactory. He then built a Jodel D-112 with the help of the Aéro-Club de Courbevoie at Saint-Cyr-l'École. It flew in 1954. Then, inspired by the Piel CP-4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoplane
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 planes. 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 a ...
