The American aerospace company Electra Aero completed its first test flight with the super-short runway of the manned prototype of the hybrid electric short takeoff and landing (eSTOL) aircraft EL-2 Goldfinch at Manassas Regional Airport in Virginia, as reported by Interesting Engineering on June 2. The prototype used in the test has 2 seats, while the final version is expected to have 9 seats.
The EL-2 Goldfinch is equipped with a unique hybrid electric propulsion system. Eight quiet electric motors powered by a large lithium battery allow the aircraft to take off and land entirely on electricity, minimizing noise in densely populated areas. An auxiliary generator enables the aircraft to conduct longer flights with a cruising speed of 320 km/h and a range of 800 km. This design not only reduces fuel consumption compared to traditional aircraft but also provides a quieter and more environmentally friendly flight experience.
One of the key innovations of the EL-2 Goldfinch is its patented lift technology. By directing airflow selectively through the wings, this technology allows the aircraft to take off and land on a super-short runway measuring only about 90 x 30 meters, equivalent to a football field.
In tests in Virginia, the aircraft took off in just 52m of runway and landed in 35m.
Thus, the EL-2 Goldfinch requires less than half the runway length needed for traditional aircraft. This breakthrough opens up new possibilities in aviation, allowing the aircraft to access challenging locations and small communities lacking traditional airport infrastructure. During the tests in Virginia, the aircraft took off using only 52m of runway and landed with 35m.
Electra focuses on reducing noise pollution. The electric motors and innovative design of the new aircraft produce very low noise levels, only about 75 decibels at a distance of over 90m, similar to the sound of a vacuum cleaner.
Electra believes that in the future, air travel will become more accessible and convenient for everyone. By utilizing super-short runways, the company’s aircraft could revolutionize regional air travel, connecting small communities, remote areas, and regions with underdeveloped transportation networks. This could lead to increased economic opportunities, enhanced connectivity, and improved quality of life for residents.
