Lange Antares 20E
The Antares is a glider built by Lange Aviation produced with three different wingspans, 18, 20 and 23 meters. The 20 and 23 meter variants can be equipped with a 42-kW electric motor and SAFT VL 41M lithium-ion batteries. The EM 42 is a fixed-shaft brushless DC electric motor (see Lange EA 42) running at 190-288 V, and drawing up to 160 A, the 42 kW motor can deliver up to 216 N.m of torque over a speed range of 160-1600 RPM with a total efficiency of 90%. Maximum continuous power is 38.5 kW, the motor weighs 29 kg, and the weight of power electronics is 10 kg. The motor turns a two-blade fixed-pitch propeller, LF-P42, constructed of composite materials, having a diameter of two meters. The battery system consists of two battery packs positioned in the leading edges of both inner wings (72 cells divided into 24 modules containing 3 cells each). The battery life is expected to be 3000 cycles or 20 years. The capacity of the battery is 41 Ah (specific energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Mid-engined Aircraft
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive com ...

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] |
Mid-wing Aircraft
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 ...

Motor Gliders
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which he ...

2000s German Sailplanes
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the complica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schempp-Hirth Quintus
The Schempp-Hirth Quintus is a single-seat 23 metre FAI Open Class, Open-Class glider (sailplane), glider built by Schempp-Hirth Development The Quintus and the Lange Antares 23E were developed in a joint venture between Lange Aviation GmbH and Schempp-Hirth. The two aircraft share a common wing design and the companies have agreed to coordinate marketing. The 18m inner section of the wing was developed by Lange with the assistance of Professor Loek Boermans of the Delft University of Technology. The outer sections have Maughmer winglets. The wings' moulds have also been used for the Lange Antares H3 experimental fuel-cell aircraft. The biggest differences between Antares 23 E and Quintus are the fuselages and the propulsion units. Lange Aviation have installed an electric system whereas the Quintus has a SOLO 2625-02i combustion engine. At 58 kg/m2 the Quintus has a wing-loading 20% higher than its predecessors and its high aspect ratio will give good climb rates in therma ...
