ZEROe Airbus, taking a new direction, announced that they are, “Exploring game-changing concept aircraft – known as ZEROe – powered by hydrogen, a disruptive zero-emission technology with the potential to reduce aircraft emissions by up to 50%.” Two seem to be evolutionary, employing a different fuel and powertrain within fairly conventional airframes.  The third, a blended-wing body (BWB) structure, emulates Boeing’s and NASA’s BWB.  All three, though, employ hydrogen to meet the planet’s need to reduce or eliminate carbon dioxide and other emissions.  All three use hydrogen hybrid power systems. The International Civil Aviation Organization (ICAO) in a 2019 report looked at the different electric and hybrid systems available.  The organization included a factor examined before in this blog.  “The …

What Has One Engine, Six Motors and Seven Propellers?

EcoPulse™, a collaboration by Airbus, Daher, and Safran is a fixed-wing distributed hybrid propulsion aircraft whose power system emulates many of the Urban Air Mobility vehicles that use an electric Vertical Take Off and Landing configuration.  Safran, notable for its gas turbines, will supply the propulsion system (excluding batteries).  The system consists of a turbogenerator (combined turbine and power generator), an electric power management system, and integrated electric thrusters (or e-Propellers) including electric motors and propellers faired neatly into the wings. EcoPulse partners claim the six small electric motors spread along the leading edge, while providing propulsion thrust, lead to a reduction of wing surface area – much of the wing gaining lift from the blown areas, lowered wingtip marginal …
