The Eviation Alice is an electric aircraft that is being developed as a commercial passenger aircraft. The manufacturer is the Israeli company Eviation Aircraft .
development
Alice is developed as a feeder plane. The aircraft is supposed to carry 9 passengers over a distance of up to 1000 kilometers. The performance parameters are thus significantly higher than those of other electric aircraft that have been presented so far. Commercial use is scheduled to begin in 2022. The first user is said to be the US company Cape Air . The manufacturer estimates the operating costs to be a fifth of those for conventional aircraft. Its use is primarily intended for commuters, as short flight routes are particularly criticized for ecological reasons.
The aircraft was presented to the public for the first time at the 2019 Paris Air Show. The first flight was originally scheduled to take place in the US in 2019, but has been postponed to 2020. On January 22, 2020, a fire in the aircraft's electrical system occurred during a ground test at Prescott Airport, Arizona . As the fire brigade observed the test, the fire was quickly extinguished. Nevertheless, the aircraft was severely damaged. In 2020 another two prototypes are to be delivered to the USA.
The unit price is said to be 4 million USD.
construction
The aircraft is designed as a low- wing aircraft with a V-tail . The teardrop-shaped hull is made of carbon fiber reinforced plastic and provides some of the buoyancy. The retractable landing gear consists of the two single-wheel main landing gear under the wings and a tail wheel. The three 260 kW electric motors from Siemens and Magnix are attached to the wing tips and the end of the fuselage and each drive adjustable pusher propellers. The aircraft is equipped with a pressurized cabin . The lithium-ion battery has a capacity of 900 kWh. Its mass is 3700 kg, which is approx. 60% of the maximum take-off mass. If one of the motors at the wing tips should fail, the electronics supplied by Honeywell would also turn down the opposite motor, thereby greatly increasing the output of the tail motor. The aircraft should remain airworthy even with the tail rotor alone. Alice is according to According to the manufacturer, the first aircraft with an electronic flight control, which is designed from the beginning on an electric drive. The motors are cooled by cooling plates embedded in the outer skin and the casing of the motors at the tips of the wings. The aircraft has two fuselage sockets. With half an hour of charging time, one hour of flight time should be possible.
