Solair I and Solair II are two German-designed electric aircraft.
The human piloted Solair I was developed from 1980 by Günther Rochelt - developer of the Musculair human-powered aircraft series - based on a Hans Farner canard design. [1] [2] It employed 2499 wing-mounted solar cells giving an output of between 1.8 kilowatts (kW), equivalent to approximately 2.4 horsepower (hp), and 2.2 kW (3.0 hp). The aircraft first flew at Unterwössen, Germany on 21 August 1983. [1] It flew for 5 hours and 41 minutes, "mostly on solar energy and also thermals". [1] The aircraft is now displayed at the German Museum in Munich. [2] The newly developed piloted Solair II made its first flight in May 1998 and further test flights that summer but the propulsion system overheated too fast. [2] Development stopped when Günther Rochelt suddenly died in September 1998.
The Solair II project began in 1996, and aimed to develop a higher-powered successor aircraft. Modelled on glider construction, the aircraft has a V-tail tail, and fin headed on each propeller for propulsion. The aircraft was manufactured in half-shells sandwich construction with honeycomb cores. With charged batteries, it required an input of 755 W power for the straight flight.
A motor glider is a fixed-wing aircraft that can be flown with or without engine power. The FAI Gliding Commission Sporting Code definition is: a fixed-wing aerodyne equipped with a means of propulsion (MoP), capable of sustained soaring flight without thrust from the means of propulsion.
The Sikorsky Cypher and Cypher II are types of unmanned aerial vehicles developed by Sikorsky Aircraft. They are vertical takeoff and landing aircraft which use two opposing rotors enclosed in a circular shroud for propulsion.
A solar vehicle or solar electric vehicle is an electric vehicle powered completely or significantly by direct solar energy. Usually, photovoltaic (PV) cells contained in solar panels convert the sun's energy directly into electric energy.
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.
The Solar Challenger was a solar-powered electric aircraft designed by Paul MacCready's AeroVironment. The aircraft was designed as an improvement on the Gossamer Penguin, which in turn was a solar-powered variant of the human-powered Gossamer Albatross. It was powered entirely by the photovoltaic cells on its wing and stabilizer, without even reserve batteries, and was the first such craft capable of long-distance flight. In 1981, it successfully completed a 163-mile (262 km) demonstration flight from France to England.
The Zephyr is a series of high-altitude platform station aircraft produced by Airbus. They were designed originally by QinetiQ, a commercial offshoot of the UK Ministry of Defence. In July 2010, the Zephyr 7 flew during 14 days. In March 2013, the project was sold to Airbus Defence and Space. In the summer of 2022, the Zephyr 8/S flew during 64 days.
The AstroFlight Sunrise was an uncrewed experimental electric aircraft technology demonstrator and the first aircraft to fly on solar power.
The Pipistrel Taurus is a Slovenian self-launched two-seat microlight glider designed and built by Pipistrel.
SHARP, short for Stationary High Altitude Relay Platform, was an experimental aircraft using beam-powered propulsion designed by the Communications Research Centre Canada (CRC) and built by the University of Toronto Institute for Aerospace Studies (UTIAS) during the 1980s. SHARP used microwaves to provide energy from a ground station that powered electric motors spinning propellers to keep the aircraft aloft. The power was also used for the onboard electronics. SHARP could remain aloft indefinitely, and was intended to be used as a sort of low-altitude communications satellite for smaller geographical areas.
Eric Raymond is an American Certified Flight Instructor, Glider (sailplane) pilot, hang gliding pilot and designer of solar-powered airplanes.
The Solar-Powered Aircraft Developments Solar One is a British mid-wing, experimental, manned solar-powered aircraft that was designed by David Williams and produced by Solar-Powered Aircraft Developments under the direction of Freddie To. On 13 June 1979 it became one of the first solar-powered aircraft to fly, after the unmanned AstroFlight Sunrise and the manned Mauro Solar Riser, and the first successful British solar-powered aircraft.
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 4+1⁄2 years earlier.
The e-Genius is a crewed electric airplane, which was developed by the Institute of Aircraft Design at the University of Stuttgart and first flew in May 2011.
The Yuneec EViva is a Chinese low-wing, two-seat motor glider that was designed by Martin Wezel is now under development by Yuneec International of Kunshan, Jiangsu.
Musculair 1 and Musculair 2 are two human-powered aircraft designed and built by German academic and engineer Günther Rochelt.
The Sunseeker Duo is a twin seat all-electric solar-recharged powered aircraft. Designed by Eric Scott Raymond, the plane can take off and achieve enough height for the motor to be switched off and follow thermals like a glider (sailplane), allowing the batteries to be recharged through the solar cells on the wings. Still in testing phase, the company, Solar Flight, does not provide information on the range.
The NASA X-57 Maxwell was an experimental aircraft being developed by NASA, intended to demonstrate technology to reduce fuel use, emissions, and noise. The first flight of the X-57 was scheduled to take place in 2023, but the program was cancelled due to problems with the propulsion system.
SolarStratos is an aeronautical project aimed at flying a solar-powered airplane for the first time to the stratosphere. The SolarStratos airplane is equipped with solar cells but is not able to fly directly on solar power, thus is accurately described as a battery powered electric airplane that is equipped with solar cells; it is planned to be the first crewed solar-equipped aircraft to enter the stratosphere.
The Airbus CityAirbus is a multinational project by Airbus Helicopters to produce an electrically powered VTOL personal air vehicle demonstrator. It is intended for the air taxi role, to avoid ground traffic congestion.
Günter Rochelt was the designer and builder of Solair I, a 16 m wingspan solar airplane ... 21st of August 1983 he flew in Solair I, mostly on solar energy and also thermals, during 5 hours 41 minutes.
