The U.S. Air Force has partnered with Electra-Aero to design and build an ultra-short take-off and landing (Ultra STOL) hybrid aircraft. This bird looks like a classic airplane with wingspan 14.6
Meters and is capable of carrying 7 passengers with one pilot. Eight electric rotors provide forward force and, in addition, supply air along the entire length of the wing and vents across the wing to provide the additional upward force needed to hold the aircraft in the air. This force helps the aircraft to take off at speeds of up to 48 km / h, and these 8 electric rotors allow the aircraft to land and take off in short runways up to 45 meters in length. The advantage of this method of lifting compared to vertical aircraft lift (eVTOL) is its efficiency and effectiveness, because traditional lift with the help of upward force under the wings of the plane (Lift) consumes less energy than the vertical lift (eVTOL) method. So the Electra, which is capable of traveling 804 km, can travel longer distances per flight. The Electra test engine has a power of 200 hp and the aircraft will be used for urban and regional short-haul flight activities, demonstration flying operations, medium-distance freight transport, and ambulance and emergency services to transport patients. .
Eviation has unveiled a production version of its Alice electric aircraft and hopes to make its first test flight this year. The company, like other electric aircraft manufacturers, hopes to serve passengers and cargo with batteries and electric propulsion over distances of 500 to 1,000 kilometers, without producing carbon dioxide emissions. In the early version of 2019, this electric aircraft was equipped with three 260 kW electric motors, one of which is located at the end of the aircraft and the other two engines are mounted on small 7-shaped rear wings of the aircraft, which the engines accelerate to the surrounding air. The fuselage provides forward propulsion and, by sending air under its wings, provides upward force for the aircraft to remain in the sky. In the production version of the aircraft in the rear tail, the 7-shaped wings of the aircraft have been turned into solid wings and an electric motor has been completely removed, and instead of three 260 kW MagniX electric motors, it has replaced two powerful 640 kW electric motors from this company. Which are installed on both sides of the fuselage. Its maximum speed is 407 kilometers per hour. The aircraft is capable of carrying 1130 kg of cargo and has enough space for 9 passengers and 2 crew.
