Meet VoltAero’s Cassio, a unique general aviation airplane with a distributed hybrid-electric propulsion system, that is taking electric aircraft to a new level. Cassio uses a combination of electric motors and an internal combustion engine in a “push-pull” configuration.The VoltAero Cassio is a family of hybrid electric aircraft being developed by startup company VoltAero.
The company plans to produce three configurations of the Cassio aircraft: the four-place Cassio 330, the six-place Cassio 480, and the ten-place Cassio 600.The Cassio will be powered by two 60 kW (80 hp) electric motors driving tractor propellers on the wing and a 170 kW (230 hp) piston engine and 150 kW (200 hp) motor driving a pusher propeller in the aft fuselage.
The combination of fuel and batteries will give it a 1,200 km (650 nmi) range with nine people aboard. It should fly up to 200 km as a pure electric aircraft, 200–600 km (110–320 nmi) as a battery-assisted mild hybrid and over 600 km using more its combustion engine. Its cruise speed should be 200 kn (370 km/h) cruise its endurance 3.5 h, which could be extended to 5 h. The production four-seater targets a 1,800 ft (550 m) field capability within a 2.5 t (5,500 lb) MTOW.
Lower noise should be allowed by the electric taxiing and take off, before hybrid power above 1,200 ft (370 m). Fuel consumption could be reduced by up to 20%, with hybrid cruise until the batteries have discharged to a 20% energy level, before recharging them with the thermal engine.//VoltAero
