A fabricante de aeronaves Bye Aerospace está desenvolvendo um avião turboélice de 8 lugares totalmente elétrico. O projeto, eFlyer 800, inclui diversas apliações tecnológicas para seu desenvolvimento e é o primeiro avião com tecnologia de propulsão totalmente elétrica, que atinge desempenho e segurança sem a utilização de CO2, além de custos operacionais baixos.
Bye Aerospace has revealed it is developing an eight-seat all-electric twin turboprop class airplane, the eFlyer 800.
Performance estimates for the eFlyer 800 include up to 320 knot cruise speed, 35,000 feet ceiling, and 500 nm range with 45-minute IFR reserves at normal cruise speed of 280 knots, according to company officials.
The new airplane will feature two wing-mounted electric motors, each with dual redundant motor windings, quad-redundant battery packs, and a full airplane parachute.
Potential features include an emergency auto-landing system, intelligent algorithm ensuring envelope protection, terrain avoidance and routing for emergency auto-land, and also an option for supplemental power solar cells and in-wheel electric taxi, company officials said.
The airplane’s 8-seat configuration consists of up to seven passengers and one or two pilots.
The eFlyer 800 will have only one-fifth the operating costs of traditional twin turboprops and is geared for the air-taxi, air-cargo, regional, and charter aircraft markets, Bye Aerospace officials add.
“The eFlyer 800 is the first all-electric propulsion technology airplane that achieves twin-turboprop performance and safety with no CO2 and extremely low operating costs,” said George E. Bye, CEO. “This type of remarkable economy and performance is made possible by the electric propulsion system and advanced battery cell technology that results in significantly higher energy densities.”
Bye Aerospace and Safran are assessing the most efficient electric powertrain for the eFlyer 800, Bye noted.
“Safran product lines with the ENGINeUS motors, rated from 50kW to 500kW/1MW and GENeUSGRID systems, perfectly fit with the Bye Aerospace portfolio of e-aircraft,” said Hervé Blanc, executive vice president and general manager power with Safran Electrical & Power. “Building upon our successful cooperation on eFlyer2 and eFlyer4, we are very proud to bring our best expertise to support Bye Aerospace in the design of the new eFlyer 800.”
Bye Aerospace is in the process of obtaining FAA Part-23 certification for the eFlyer 2 for the professional flight training mission and the four-seat eFlyer 4 for air taxi, cargo, and advanced training.
