Electra Aero has found worldwide interest in its electric ultra-short take-off and landing airplane, an eight-motor craft capable of taking off and landing across most jet-size runways. Producing such an aircraft takes great design, appropriately-designed landing sites, a well-integrated infrastructure, and financial backing for the total package. Electra Aero for the Design Powered by a hybrid generator driving four electric motors, Electra Aero’s aircraft uses “blown lift” to take off over very short distances – less than 150 feet, according to the company. Ben Marchionna, director of technology and innovation at Electra Aero, explains, “eVTOLs use electric propulsion to take off and land vertically – many of these concepts then transition from vertical flight to forward flight with a wing providing the lift once in cruise… Vertical flight requires significantly more power, resulting in an enormous payload, range, and cost penalty. eSTOLs use electric propulsion and an aerodynamic technique called blown lift to takeoff over distances as short as 100 …

eCSTOL: Longer Range Commutes on Less Power

Competition is growing in the electric Vertical Take Off and Landing market, with 407 potential builders listed in eVTOL News.  Vertical flight takes power, though, and with available batteries limiting range, most such vehicles can make only short hops.  Alternatives that allow speedier, longer flights, in the form of electric Conventional Short Take Off and Landing (eCSTOL) aircraft are in development. Such craft offer the benefit of requiring less power for takeoffs and climbs, being more aeronautically-based than power-based.  Airflow, for instance, claims operating costs for their eCTSOL craft is one-third that of an eVTOL or helicopter. We will look at three eCSTOL craft that seem to making headway at this time.  The infrastructure (in two cases below) to support their flight may already exist. Airflow Curt Epstein, writing in Future Flight, under the headline, “Infrastructure Needs for eSTOL and eVTOL Aircraft May be Closer than Imagined,” notes the “intense study” being undertaken.  Speaking at the Vertical Flight Society’s  Electric …
