Zunum Aero, a pioneer in electric aviation, is taking a critical step towards realizing the delivery of an economical, efficient hybrid-to-electric aircraft by the early 2020s.
The new Zunum aircraft will deliver breakthrough operating costs of 8 cents per available seat mile or $250 per hour for the aircraft, which is 60-80 percent lower than comparable conventional aircraft of comparable size. The ZA10 aircraft is designed to cruise and land on turbo-generator power alone, offering full redundancy.
Zunum Aero selected aerospace expert Safran Helicopter Engines for its hybrid-to-electric commercial aircraft, which will be available in the early 2020s. Safran Helicopter Engines will provide a new generation engine turbine to drive the Zunum ZA10’s electrical generator. This turbo-generator will power this 12-seat, hybrid-to-electric 700-mile commercial aircraft, driving extraordinarily low operating costs, offering unprecedented door-to-door travel times that are 2 to 4 times faster than today. Zunum expects to light up thirty thousand airports around the world with frequent and affordable air service.
The Zunum aircraft under development, internally dubbed the ZA10, is the first in the company’s family of regional, hybrid-to-electric aircraft. It will be powered by dual power sources: propulsion batteries, and a Safran turboshaft from the 1,700 to 2,000 shaft horsepower (shp) Ardiden range.
This new model, the Ardiden 3Z, will be used as a hybrid power source achieving demanding cost, efficiency and uptime requirements. It will be coupled with an electric generator, and the integrated turbo-generator will deliver 500kW of electric power to supplement the battery packs on key stages of flight and over long ranges. Upgrades such as advanced materials and integrated lifecycle management for hybrid service will dramatically reduce operating costs of the engine by extending the life of critical components.
“The Zunum ZA10 aircraft will bring breakthrough performance to regional aviation, paving the way to fast, electrified, affordable high-speed air services to communities everywhere,” said Matt Knapp, co-founder and CTO of Zunum Aero.
