D'Yves Yvasion 2000
The D'Yves Yvasion 2000 ( en, Evasion) is a family of French paramotors that was designed by Yves Hélary and produced by D'Yves Air Pub of La Chapelle-en-Vexin for powered paragliding. Now out of production, when it was available the aircraft was supplied complete and ready-to-fly.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 66. Pagefast Ltd, Lancaster UK, 2003. ISSN 1368-485X Design and development The Yvasion 2000 series was designed to comply with the US FAR 103 Ultralight Vehicles rules as well as European regulations. It features a paraglider-style wing, single-place accommodation and a single engine in pusher configuration with a reduction drive and a two-bladed wooden propeller. The individual models differ by the installed powerplant. As is the case with all paramotors, take-off and landing is accomplished by foot. Inflight steering is accomplished via handles that actuate the canopy brakes, creating roll and yaw. Varia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fly 130
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2000s French Ultralight Aircraft
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the complica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. 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 In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or Scavenging (automotive), scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scotland, Scottish engineer Dugald Clerk, who pa ...

Solo 210
The Hirth F-36 is a single-cylinder, two-stroke, carburetted aircraft engine designed for use on ultralight aircraft, especially powered paragliders and ultralight trikes. It is noted for its extremely small equipped weight of including exhaust system, reduction drive and carburetor. It is manufactured by Hirth of Germany. The F-36 was formerly known as the Solo 210, before the design was purchased by Hirth. Development The engine uses free air cooling, single capacitor discharge ignition, with a single integral pump-type carburetor. The cylinder walls are electrochemically coated with Nikasil. Standard starting is recoil start Rope start (also called pull start or ''rewind start'') is a method of starting an internal combustion engine, usually on small machines, such as lawn mowers, chainsaws, ultralight aircraft, small outboard motors and portable engine-generators.

JPX D330
The JPX D-320 and D330 are a family of French twin-cylinder, horizontally opposed, two-stroke aircraft engines.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page G-4 Cybair Limited Publishing, 2001. The engine was introduced specifically for the powered paraglider market, as part of the company's comeback efforts following going out of business in the early 1990s. Production of the engine had ended by 2012. Design and development The engine has two cylinders in a horizontally opposed configuration, with cooling fins on the cylinders. The single ignition system uses capacitor discharge ignition. Fuel is metered by a single Tillotson carburetor. Starting is only by electric start, without recoil start as an option. The D-320 has a redline rpm of 6600 and uses a belt reduction drive of 2.38:1. Its weight of just gives the engine a high power-to-weight ratio.

Reduction Drive
A reduction drive is a mechanical device to shift rotational speed. A planetary reduction drive is a small scale version using ball bearings in an epicyclic arrangement instead of toothed gears. Reduction drives are used in engines of all kinds to increase the amount of torque per revolution of a shaft: the gearbox of any car is a ubiquitous example of a reduction drive. Common household uses are washing machines, food blenders and window-winders. Reduction drives are also used to decrease the rotational speed of an input shaft to an appropriate output speed. Reduction drives can be a gear train design or belt driven. Planetary reduction drives are typically attached between the shaft of the variable capacitor and the tuning knob of any radio, to allow fine adjustments of the tuning capacitor with smooth movements of the knob. Planetary drives are used in this situation to avoid "backlash", which makes tuning easier. If the capacitor drive has backlash, when one attempts to tune i ...
