WDLA UK, Lancaster UK, 2011. Tacke, Willi; Marino Boric; et al: ''World Directory of Light Aviation 2015-16'', page 231. Flying Pages Europe SARL, 2015. The company was founded in 2008 as Enstroj, to produce the Emrax line of engines, but the company name was later changed to Emrax. Initially located in Radomlje, the company was relocated to Kamnik. The company is organized as a ''družba z omejeno odgovornostjo'', a Slovenian private Limited Liability Company. History Sušnik conducted the first electric-powered aircraft flight in Slovenia and the third worldwide in 2005, but experienced an engine failure due to the design limitations of the commercial motor he used.

Electric Aircraft
An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines. Crewed flights in an electrically powered airship go back to the 19th century, and to 1917 for a tethered helicopter. Electrically powered model aircraft have been flown at least since the 1970s, preceding the small unmanned aerial vehicles (UAV) or drones used today. Small UAS could be used for parcel deliveries, and larger ones for long-endurance applications: aerial imagery, surveillance, telecommunications. The first crewed free flight by an electrically powered aeroplane, the MB-E1, was made in 1973, and most crewed electric aircraft today are still only experimental prototypes. Between 2015 and 2016, Solar Impulse 2 completed a circ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Kamnik
Kamnik (; german: Stein''Leksikon občin kraljestev in dežel zastopanih v državnem zboru,'' vol. 6: ''Kranjsko''. 1906. Vienna: C. Kr. Dvorna in Državna Tiskarna, pp. 26–27. or ''Stein in Oberkrain'') is a town in northern Slovenia. It is the central settlement of the Municipality of Kamnik. It encompasses a large part of the Kamnik Alps and the surrounding area. The town of Kamnik has three castles as well as many examples of historical architecture. History The name Kamnik was first mentioned in the 11th century. The first time it was mentioned as a town was in 1229, when it was an important trading post on the road between Ljubljana and Celje. This makes the town one of the oldest in Slovenia. In the Middle Ages, Kamnik had its own mint and some aristocratic families among its residents. The town was among the most influential centers of power for the Bavarian counts of Andechs in the region of Carniola at the time. The only remnant of the Bavarian nobility are the tw ...

Slovenia
Slovenia ( ; sl, Slovenija ), officially the Republic of Slovenia (Slovene: , abbr.: ''RS''), is a country in Central Europe. It is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the southeast, and the Adriatic Sea to the southwest. Slovenia is mostly mountainous and forested, covers , and has a population of 2.1 million (2,108,708 people). Slovenes constitute over 80% of the country's population. Slovene, a South Slavic language, is the official language. Slovenia has a predominantly temperate continental climate, with the exception of the Slovene Littoral and the Julian Alps. A sub-mediterranean climate reaches to the northern extensions of the Dinaric Alps that traverse the country in a northwest–southeast direction. The Julian Alps in the northwest have an alpine climate. Toward the northeastern Pannonian Basin, a continental climate is more pronounced. Ljubljana, the capital and largest city of Slovenia, is geogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Re ...

Electric Motor
An electric motor is an Electric machine, electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a Electromagnetic coil, wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be Brushed motor, brushed or Brushless motor, brushless, single-phase, Two-phase electric power, two-p ...

Light Aircraft
A light aircraft is an aircraft that has a maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308. Aviation Supplies & Academics, 1997. Light aircraft are used as utility aircraft commercially for passenger and freight transport, sightseeing, photography, and other roles, as well as personal use. Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft B200 Super King Air. Uses Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flight instruction. The majority of personal aircraft are light aircraft, the most popular in history being the Cessna 172, and most popular in modern history being the Cirrus SR22 and Robinson R44.
