History of solar aviation

Polaris solar PV net news: Sun power may not be the world’s first solar-powered aircraft, but it’s definitely one of the most ambitious airplane. After all, overload at night by solar-powered aircraft has never been achieved before flight.

In the 1970 of the 20th century, appearing on the market that can afford solar panels, solar energy is also the beginning of the history of aviation. Starting from model aircraft, until in the 1980 of the 20th century, appeared in the world’s first manned solar planes.

History of solar aviation

In the United States, by Paul ˙ McGrady (PaulMacCready) led the team designing the aircraft “phantom Penguin” (theGossamerPenguin), and for the rest of the “Sun challenger” (theSolarChallenger) has paved the way. “Sun challenger” maximum power of 2.5 kilowatts, in 1981, successfully flew over the English channel. It proceed from the voyage of several hundreds of kilometers, could fly for hours at a time. Meanwhile, Europe’s Gunter ˙ Rochelt (PaulMacCready) also achieved its “sunshine 1th” (theSolarChallenger), the first flight of the aircraft. Its 2,500 on photovoltaic cells, can create a total power of 2.2 kW.

In 1990, the American Eric ˙ Raymond drive “Sunseeker”, solar-powered aircraft, 21 flying over United States territories, totaling 121 hours flight time, before and after nearly 2 months. Longest flying distance of 400 km. “Chasing the Sun” is a solar-powered glider the wing angle of 30 degrees, net weight of 89 kilograms, equipped with amorphous silicon solar cells.

In the mid 1990 of the 20th century, and few plane turned out, join the beierlinge contest (the’Berblinger’competition). The goal of this competition is, the aircraft can climb under battery power to a height of 450 meters above sea level, and at least 500 Watts/square meter solar power supplies maintain level flight, equivalent to the tropical midday sun can provide energy.

The race was founded in 1996 by Germany Stuttgart University (StuttgartUniversity) Walter ˙ Professor nicimanen (Voit-Nitschmann) led the team won. They used a plane named Icarus 2nd, a wingspan of 25-meter-wide fuselage with 26 square meters of solar panels.

Also worth mentioning are for United States aviation environment company (AeroVironment) making the Helios aircraft, although it cannot be loaded, but its status is still to be reckoned with. It can realize remote control aircraft plane has a wingspan of more than 70 metres, and in 2001 hit a record climbing height of nearly 30,000 meters above sea level. But two years later, it hit air during the flight, crashed in the Pacific Ocean.

In 2005, the United States ACPropulsion founder Alan ˙ expedition (AlanCocconi) manipulation a wingspan 5 m wide, unmanned aircraft, relying on solar-powered flight for 48 hours in a row. As the aircraft was carrying solar panels can collect and store energy, this vehicle’s first complete night flight,

July 9, 2010 to 23rd QuinetiQ’s Zephyr drone realizes up to 336 hours and 22 minutes of nonstop flight, the plane weighs 27 kilograms, a wingspan of 12 meters, altitude of 21562 meters above sea level.
