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. 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 publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 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 ''Forbes'' survey of closely held U.S. businesses sold a trillion dollars' worth of goods and service ...

Aircraft Manufacturers Of Bulgaria
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-a ...

Side-by-side Configuration
Tandem, or in tandem, is an arrangement in which a team of machines, animals or people are lined up one behind another, all facing in the same direction. The original use of the term in English was in ''tandem harness'', which is used for two or more draft horses, or other draft animals, harnessed in a single line one behind another, as opposed to a pair, harnessed side by side, or a team of several pairs. The tandem harness allows additional animals to provide pulling power for a vehicle designed for a single animal. The English word ''tandem'' derives from the Latin adverb , meaning ''at length'' or ''finally''. It is a word play, using the Latin phrase (referring to time, not position) for English "at length, lengthwise". Tandem bicycles are named for their tandem seating, a more common arrangement than side-by-side " sociable" seating. ''Tandem'' can also be used more generally to refer to any group of persons or objects working together, not necessarily in line. Automo ...

Niki Kallithea
The Niki Kallithea (the best view) is a Bulgarian autogyro designed and produced by Niki Rotor Aviation of Pravets, introduced in 2011. The aircraft is supplied complete and ready-to-fly.Tacke, Willi; Marino Boric; et al: ''World Directory of Light Aviation 2015-16'', page 196. Flying Pages Europe SARL, 2015. Design and development The Kallithea is a development of the 2009 Niki Lightning, differing mainly in its use of a conventional two-tube tail boom that passes under the pusher propeller instead of mounting the tail boom through the propeller hub. The Kallithea features a single main rotor, a two-seats-in tandem enclosed cockpit with fold-up doors, tricycle landing gear and a four-cylinder, liquid and air-cooled, four stroke Rotax 912 or six-cylinder, liquid cooled side-valve four-stroke flat six 4-litre gasoline D-Motor LF39 aircraft engine in pusher configuration.

It was introduced in 2009 Design and development The Lightning's cockpit pod accommodates a pilot and passenger in tandem. The main rotor is two-bladed, with a pre-rotator. Unconventionally the tail boom is mounted though the centre of the propeller shaft.Tacke, Willi; Marino Boric; et al: ''World Directory of Light Aviation 2015-16'', page 196. Flying Pages Europe SARL, 2015. The boom may be unbolted and removed to aid access to the engine and prop. There is a choice of two very compact D-Motor engines (both liquid-cooled horizontally-opposed A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft.
