Ampaire announced a key exclusive supplier for the hybrid-electric propulsion system it is developing for its Eco Caravan aircraft, an upgrade to the current Cessna Grand Caravan. Ampaire will use a RED Aircraft AO3 series compression ignition engine rated to 550 hp (405 kW) in an integrated parallel configuration. The RED engine provides the base power and the Ampaire electrical system provides the peak power.
Under the terms of an MOU between the companies, the two will work to commercialize electrified propulsion aircraft, with Ampaire developing complete hybrid-electric propulsion systems and certifying them for various applications up to 800 hp, while RED Aircraft will develop, certify, and supply Jet A/SAF compatible engine subsystems to Ampaire.
The new propulsion system for the Eco Caravan offers substantial benefits to users and will be the first in a series of electrified fixed-wing aircraft that reduce aviation’s carbon footprint.
Ampaire conducted the first Eco Caravan hybrid powertrain ground runs in April 2022, with plans to fly the aircraft in the second half of the year. The company is working with the FAA to achieve supplemental type certificate (STC) approval by 2024.
The Eco Caravan will retain the payload capabilities of the Grand Caravan, carrying up to 11 passengers or 2,500 pounds of cargo. Range improves to 1,100 nautical miles.
“The modern, powerful and ultra-fuel-efficient RED engines have exactly the right characteristics for the Eco Caravan’s hybrid-electric propulsion system and for many other upgrades or all-new designs we may pursue,” said Ampaire CEO Kevin Noertker. “We are very pleased to take this first step in collaboration with a company that shares our goal to decarbonize aviation while reducing costs for aircraft operators and their passengers.”
“RED Aircraft sees enormous potential for hybrid-electric aircraft and believes the Eco Caravan is just the first step to bringing a new level of efficiency and vastly lower emissions to a large swath of aviation,” said Jürgen Schwarz, CEO. “We are thrilled to be pursuing these opportunities hand-in-hand with Ampaire.”
