Safe, efficient and eco-friendly: these are the keywords for VoltAero’s aircraft design – bringing a distributed hybrid-electric power system with electric motors and an internal combustion engine into a “push-pull” propulsion configuration that delivers a total power output of 440 kilowatts.
VoltAero’s “pull” is provided by two forward-facing 60-kilowatt electric motors on the wings with multi-blade propellers. These motors are used in nearly-silent takeoffs and landings for eco-efficient and neighbor-friendly operations at airports.
The “push” comes from a 170-kilowatt internal combustion engine that drives a multi-blade “pusher” propeller during cruise flight. This engine also is used to charge the on-board batteries for the aircraft’s electric motors.
Installed along with the internal combustion engine is a 150-kilowatt electric motor, which together create VoltAero’s aft-fuselage power module. The power module provides an added safety function, offering an immediate auto-start capability with its electric motor to drive the “pusher” propeller if the forward-facing “puller” electric motors encounter a problem during critical moments of flight, particularly the takeoff.
