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] |
Airbus A³ Vahana
The Airbus Vahana (Sanskrit: ''Vāhana'', or Vahanam literally means "vehicle") was an electric-powered eight-propeller VTOL personal air vehicle prototype financed by A³ (pronounced "A-cubed"), by Airbus and Airbus Urban Mobility. The Vahana project started in 2016 as one of the first projects at A³, the advanced projects and partnerships outpost of Airbus Group in Silicon Valley. Airbus "envision Vahana being used by everyday commuters as a cost-comparable replacement for short-range urban transportation like cars or trains". It was planned to be a part of urban air mobility. The project was finished in December 2019. Development The convertiplane aircraft design, funded by the European aircraft manufacturer Airbus, called Vahana (Sanskrit: "vehicle"), started in 2016. It was being developed at A³ (A-cubed), the expanded project and partnership outpost of Airbus in Silicon Valley. Airbus said "Our work on this demonstrator confirms our belief that fully autonomous veh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iron Bird (aviation)
An iron bird is a ground-based test device used for prototyping and integrating aircraft systems during the development of new aircraft designs. Aircraft systems are installed into the iron bird so their functions can be tested both individually and in correlation with other systems. Overview Iron birds are used for system integration, reliability testing, and shakedown testing of aircraft systems such as landing gear, avionics, hydraulics, and flight controls. The components may be arranged roughly in the same layout as they will be in the final aircraft design, but left accessible for ease of maintenance. Some iron birds also include a flight deck so that testing can include pilot inputs and simulated flight profiles, and can be used in pre-flight pilot training. Others are used for testing of propulsion systems. Iron birds can also be used after aircraft certification for troubleshooting ongoing issues and for testing of proposed modifications prior to fleet integration ...

Traffic Congestion
Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s. When traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream, this results in some congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads. As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is known as a traffic jam or (informally) a traffic snarl-up. Traffic congestion can lead to drivers becoming frustrated and engaging in road rage. Mathematically, traffic is modeled as a flow through a fixed point on the route, analogously to fluid dynamics. Causes Traffic congestion occurs when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donauwörth
Donauwörth () is a town and the capital of the Donau-Ries district in Swabia, Bavaria, Germany. It is said to have been founded by two fishermen where the rivers Danube (Donau) and Wörnitz meet. The city is part of the scenic route called "Romantische Straße" (Romantic Road). The city is situated between Munich and Nuremberg, 46 km north of Augsburg. History Donauwörth grew up in the course of the 11th and 12th centuries under the protection of the castle of Mangoldstein, became in the 13th century a seat of Duke Ludwig II of Bavaria, who, however, soon withdrew to Munich to escape from his wife, Duchess Maria of Brabant, whom he had there beheaded on an unfounded suspicion of infidelity. The town received the freedom of the Holy Roman Empire in 1308, and maintained its position in spite of the encroachments of Bavaria till 1607, when the interference of the Protestant inhabitants with the abbot of the Heilig-Kreuz called forth an imperial law authorizing the duke of Bav ...

Thales Group
Thales Group () is a French multinational company that designs, develops and manufactures electrical systems as well as devices and equipment for the aerospace, defence, transportation and security sectors. The company is headquartered in Paris' business district, La Défense, and its stock is listed on the Euronext Paris. Having been known as Thomson-CSF since its foundation in 1968, the company was rebranded ''Thales'' (named after the Greek philosopher Thales and pronounced , reflecting its pronunciation in French) in December 2000. A communication audit, launched in spring that year, highlighted Thomson-CSF's image deficit, particularly among the young French graduates it was seeking to recruit. The wish to liven up its image as well as the expansion of its business worldwide were cited among the reasons for the change. Thales is partially owned by the French State and operates in more than 56 countries. It had 80,000 employees and generated €18.4 billion in revenues in ...

European Organisation For Civil Aviation Equipment
The European Organisation for Civil Aviation Equipment (EUROCAE) deals exclusively with aviation standardisation, for both airborne and ground systems and equipment. It was created in 1963 in Lucerne, Switzerland by a decision of the European Civil Aviation Conference as a European forum focusing on electronic equipment for air transport. EUROCAE has now been operating for more than 50 years as a non-profit organisation whose membership comprises aviation stakeholders made up of regulators, manufacturers, services providers, users (such as airlines and airports) and academia. The membership is not limited to the European region. From the outset, EUROCAE has developed performance specifications and other documents exclusively dedicated to the aviation community. EUROCAE documents are widely referenced by the International Civil Aviation Organisation (ICAO) as Guidance Material and by the European Aviation Safety Agency (EASA) as means of compliance to European Technical Standard ...

Aircraft Noise Pollution
Aircraft noise pollution refers to noise produced by aircraft in flight that has been associated with several negative stress-mediated health effects, from sleep disorders to cardiovascular ones. Governments have enacted extensive controls that apply to aircraft designers, manufacturers, and operators, resulting in improved procedures and cuts in pollution. Sound production is divided into three categories: * Mechanical noise—rotation of the engine parts, most noticeable when fan blades reach supersonic speeds. * Aerodynamic noise—from the airflow around the surfaces of the aircraft, especially when flying low at high speeds. * Noise from aircraft systems—cockpit and cabin pressurization and conditioning systems, and Auxiliary Power units. Mechanisms of sound production Aircraft noise is noise pollution produced by an aircraft or its components, whether on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, duri ...
