Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft Manufacturers Of The Czech Republic And Czechoslovakia
An 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 by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. 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, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Low-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 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 ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also ...

Conventional Landing Gear
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velešín
Velešín (; german: Weleschin) is a town in Český Krumlov District the South Bohemian Region of the Czech Republic. It has about 3,900 inhabitants. Administrative parts Villages of Bor, Chodeč, Holkov and Skřidla are administrative parts of Velešín. Geography Velešín is located about east of Český Krumlov and south of České Budějovice. It lies in the Gratzen Foothills. It is situated on the shore of the Římov Reservoir, built on the Malše river. History The first written mention of Velešín is from 1266, when the local castle was documented. The castle and the settlement were probably founded in the 13th century. From 1387 until 1611, Velešín was a property of the Rosenberg family. During this era, the village was promoted to a market town. The originally separate estate was merged with the Nové Hrady estate, and the importance of the castle declined. In the 1480s, the castle was abandoned, and gradually fell into disrepair.

UL-Jih Evolution
The UL-Jih Evolution is a conventionally laid out, two-seat, high-wing, single-engine ultralight, designed and built in the Czech Republic. Two variants were available in 2010. Design and development The first version of the Evolution, originally designed by Jaroslav Sedláĉek of the Czech company UL-Jih was marketed by WD Flugzeugleichtbau of Germany as the Dallach D.5 Evolution with series production starting in 2002. UL-Jih fabricated both this model and the earlier D.4 Fascination and claimed sole production and marketing rights to both when WD Flugzeugleichtbau ceased trading in 2005, though those rights are challenged by Swiss Light Aircraft AG who build their own versions. The Evolution is an all-composite aircraft, which uses the same cantilever wings, control surfaces and empennage as the Fascination but has a high-wing configuration, rather than the latter's low wing. The wing is of trapezoidal plan, with ailerons that have external balance trim tabs and sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The UL-Jih Fascination, also called the Fascination F100, is a conventionally laid out, two seat, low wing, single engine ultralight, designed and built in the Czech Republic. Two variants were offered in 2010.Tacke, Willi; Marino Boric; et al.: ''World Directory of Light Aviation 2015–16'', page 50. Flying Pages Europe SARL, 2015. Design and development The Fascination F100 is an advanced version of the ultralight/VLA airplane which was based on the all composite VLA layout of the Fascination (D4BK) by Wolfgang Dallach. During and after his collaboration with Wolfgang Dallach, Jaroslav Sedláĉek from UL-Jih in the Czech Republic made own contributions to the design which finally led to today's UL-Jih F-100. The Fascination was marketed by WD Flugzeugleichtbau of Germany as the Dallach D.4 Fascination. This was an aircraft of mixed construction, including wood, composites and steel components with fabric covering. It first flew in 1996. An all-composites version, the ...
