Prototype EL-2 Goldfinch Completes Successful Flight Test
Electra Aero, a United States-based aerospace company, has successfully completed its first flight test of the manned hybrid electric short takeoff and landing (eSTOL) aircraft prototype, the EL-2 Goldfinch, at Manassas Regional Airport in Virginia.
Advanced Hybrid Electric Propulsion System
The EL-2 Goldfinch prototype is powered by a unique hybrid electric propulsion system. Eight quiet electric motors, powered by a large lithium battery pack, enable the aircraft to take off and land purely on electric power, minimizing noise pollution in populated areas. A range-extending generator allows the aircraft to fly longer distances at a cruising speed of 320 kph and a range of 800 km. This design not only reduces fuel consumption compared to conventional aircraft but also provides a quieter and more environmentally friendly flying experience.
Patented Lift Technology
One of the key innovations of the EL-2 Goldfinch is its patented lift technology. By selectively directing airflows over the wings, this technology allows the aircraft to take off and land on ultra-short runways of approximately 90 x 30 meters, comparable to the size of a football field.
Ultra-Short Takeoff and Landing Capabilities
During the Virginia test flight, the aircraft took off using only 52 meters of runway and landed in 35 meters. This represents less than half the runway length required by traditional aircraft. This breakthrough opens up new possibilities in aviation, enabling access to challenging locations and smaller communities that lack traditional airport infrastructure.
Reduced Noise Pollution
Electra emphasizes noise pollution reduction. The aircraft's electric motors and innovative design result in ultra-low noise levels of around 75 decibels at a distance of over 90 meters, similar to the sound of a vacuum cleaner.
Enhanced Air Travel Accessibility
Electra envisions a future where air travel becomes more accessible and convenient for everyone. By utilizing ultra-short runways, the company's aircraft could revolutionize regional air mobility, connecting smaller 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.
