Coax-P
The Coax-P is a contra-rotating propeller developed by NeuraJet of Senftenbach, Austria and Sun Flightcraft of Innsbruck, Austria for the Rotax 503 and Rotax 582 aircraft engines for use on ultralight aircraft.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 70. Pagefast Ltd, Lancaster UK, 2003. ISSN 1368-485X Design and development The Coax-P was designed by Hans Neudorfer of NeuraJet and Herbert Hofbauer of Sun Flightcraft. The propeller increases thrust by 15-20% over single propellers and reduces noise levels, especially low frequency noise, while eliminating torque effects. The propeller system was designed for ultralight trikes and powered parachutes. The latter are especially sensitive to torque effects and the propeller design addresses that issue. The design has two propellers, each with two composite, ground adjustable blades and uses a 3.7:1 gear box type reduction drive. The two propellers are powered by two meshing and ...

Archive
An archive is an accumulation of historical records or materials – in any medium – or the physical facility in which they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative, or social activities. They have been metaphorically defined as "the secretions of an organism", and are distinguished from documents that have been consciously written or created to communicate a particular message to posterity. In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paramotor
Paramotor is the generic name for the harness and propulsive portion of a powered paragliding, powered paraglider ("PPG"). There are two basic types of paramotors: foot launch and wheel launch. Foot launch models consist of a frame with harness, fuel tank, engine, and propeller. A hoop with protective netting primarily keeps lines out of the propeller. The unit is worn like a large backpack to which a Paraglider is attached through carabiners. Wheel launch units either come as complete units with their own motor and propeller, or as an add-on to a foot-launch paramotor. They usually have 3 (trike) or 4 (quad) wheels, with seats for one or two occupants. These are distinct from powered parachutes which are generally much heavier, more powerful, and have different steering. The term was first used by Englishman Mike Byrne in 1980 and popularized in France around 1986 when La Mouette began adapting power to the then-new paraglider wings. Power plants are almost exclusively small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chainsaw
A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, and harvesting of firewood. Chainsaws with specially designed bar-and-chain combinations have been developed as tools for use in chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete during construction developments. Chainsaws are sometimes used for cutting ice; for example, ice sculpture and winter swimming in Finland. History In surgery The origin of chain saws in surgery is debated. A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively. It was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is for use in non-certified aircraft operating in day visual flight rules. Production of the engine ended at the end of 2021. Development The Rotax 582 is based upon the earlier Rotax 532 engine design and was designed for ultralight aircraft.Raisner, William: ''LEAF catalog'', pages 6-105. Leading Edge Airfoils, 1995. The 582 increased the bore from the 532 engine's . This increased the displacement from to , an increase of 11%. The increased displacement had the effect of flattening out the 532's torque curve and allowed the 582 to produce useful power over a wider rpm range. Reliability over the 532 was also improved. The 582 features liquid-cooled cylinder heads and cylinders with a rotary intake valve. Cooling is via an externally mounted radiator. Lubrication is either by use ...
