Solar Riser
The Mauro Solar Riser is an American biplane ultralight electric aircraft that was the first crewed aircraft to fly on solar power. It was also only the second solar-powered aircraft to fly, after the uncrewed AstroFlight Sunrise, which had first flown years earlier. Design and development The president of Ultralight Flying Machines, Larry Mauro, created the Solar Riser by converting a stock UFM Easy Riser hang glider to solar power. Normally foot-launched, the Solar Riser had wheeled landing gear added. Power is supplied by a Bosch electric starter motor of connected to a 30 volt DC Nickel-cadmium battery pack taken from a Hughes 500 helicopter, powering a propeller through a reduction drive made from a timing belt and two pulleys. The battery was charged by a series of photovoltaic solar panels mounted in the top wing that provided 350 Watts of power. The solar cells were not sufficient to provide all power in flight, so all flights were made by recharging the battery ... [...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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Biplanes
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 o ...

Photovoltaics
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation generates no pollution and no greenhouse gas emissions, it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required in PV system m ...

Solar-powered 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 circu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft First Flown In 1979
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 ball ...

1970s United States Experimental Aircraft
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon).

EAA AirVenture Oshkosh
EAA AirVenture Oshkosh (formerly the EAA Annual Convention and Fly-In), or just Oshkosh, is an annual air show and gathering of aviation enthusiasts held each summer at Wittman Regional Airport and adjacent Pioneer Airport in Oshkosh, Wisconsin, United States. The southern part of the show grounds, as well as Camp Scholler, are located in the town of Nekimi and a base for seaplanes on Lake Winnebago is in Black Wolf. The airshow is arranged by the Experimental Aircraft Association (EAA), an international general aviation organization based in Oshkosh, and is the largest of its kind in the world. The show lasts a week, usually beginning on the Monday of the last full week in July. During the gathering, the airport's control tower, frequency 118.5, is the busiest in the world. History EAA was founded in Hales Corners, Wisconsin in 1953 by aircraft designer and military aviator veteran Paul Poberezny, who originally started the organization in the basement of his home for bui ...

Rubidoux, California
Rubidoux ( ) was a census-designated place and unincorporated community in Riverside County, California, until July 1, 2011, when it became a neighborhood of the newly formed city of Jurupa Valley. The city is located within Southern California's Inland Empire region, which is part of the Greater Los Angeles Area. Along with the rest of Jurupa Valley, Rubidoux has transformed from a rural area of quarries and dairy farms, in mid to late 20th century, to a suburb of the two larger regions. As of the 2010 census, the population was 34,280, up from 29,180 at the 2000 census.
