Airflow and Electra Unveil eSTOL Designs
In early June, Electra.aero and Airflow.aero announced major news for their electric short takeoff and landing (eSTOL) designs. Airflow, based in the San Francisco Bay Area, announced that it will supply 50 eSTOL aircraft (shown) to Anchorage-based regional airline, Ravn Alaska. Airflow said this now takes its total order book to more than $200M for its 10-propeller, hybrid-electric eSTOL aircraft, with entry into service planned for 2025.
The Falls Church, Virginia-based Electra unveiled its eight-propeller hybrid-electric design. Its "blown lift" technology — where the electric motor-driven propellers blow air over the entire span of the wing and its flaps — allows energy-efficient takeoff and landings at speeds below 30 mph (48 km/h) while cruising at high-speeds of 200 mph (320 km/h). Electra announced in late June that it had received a Phase II Small Business Innovative Research (SBIR) contract award from Agility Prime to support the development of its ultra-short eSTOL technology.
