Two landmark occasions on the planet of electrical energy powered flight came about in California in current weeks. On October 29, a modified Robinson 44 (eR44) helicopter powered with a magniX magni250 electrical propulsion unit (EPU) flew from Jacqueline Cochran Regional Airport to Palm Springs Worldwide Airport, a 20-minute flight that marks the primary totally electrical helicopter flight between airfields.
Then, on November 18 at Camarillo Airport, Ampaire’s Eco Caravan, a nine-seat regional plane with a totally built-in hybrid-electric propulsion system, made its first flight—climbing to three,500 ft and flying for 33 minutes earlier than a protected touchdown.
The 2 new plane—a helicopter and a regional turboprop aircraft—illustrate the vary of potentialities out there with electrical flight.
All-electric helicopter developed for carbon-free human organ transportation
The modified eR44 is the fruit of a partnership by electric-propulsion flight developer magniX and Tier 1 Engineering, specialists within the design and growth of electrical plane. The magniX EPU was retrofitted into the helicopter along with a battery system developed by Tier 1 Engineering, in line with a magniX information launch.
The eR44 is designed to ship human and manufactured organs for transplant with zero carbon emissions on the level of use.
Tier 1 is creating the magniX-powered eR44 for Lung Biotechnology PBC, a subsidiary of United Therapeutics Company, a biotechnology firm devoted to addressing the extreme scarcity of transplantable organs within the US.
“Constructing from our first flight of the eR44 helicopter final June, the efficiently accomplished point-to-point flight takes us a step nearer to the sustainable transport of life-saving organs,” said Nuno Taborda, CEO of magniX. “magniX is happy to be a part of an initiative that may positively have an effect on these in want of pressing medical care. That is solely the beginning of the functions for electrical helicopters, which have a shiny future as low-cost, carbon-free, dependable alternate options to combustion engine fashions.”
Since December 2019, magniX has additionally offered the expertise to energy plenty of first flights, together with that of Harbour Air’s “eBeaver,” a Cessna “eCaravan” and, in September 2022, Eviation’s all-electric commuter plane, Alice.
Tier 1 Engineering is at the moment working with the FAA on the eR44 mission to acquire a Supplemental Sort Certificates (STC). Lung Biotechnology PBC plans to accumulate a fleet of sustainable plane to move transplant organs.

First hybrid-electric regional plane flight exhibits environmental advantages
The 33-minute first flight of the hybrid Eco-Caravan on November 18 was to make preliminary checks of the propulsion system. The craft took off from Camarillo Airport, then climbed to three,500 ft at full energy, combining energy from the combustion engine and electrical engine. Check pilot Elliot Seguin then throttled again to a cruise setting, decreasing load on each energy sources. He spent roughly 20 minutes testing varied energy settings whereas finding out temperatures and different readings earlier than making a descent and remaining method to Camarillo at a low energy setting. “The Eco Caravan propulsion system carried out simply as anticipated,” said Seguin. “It was easy and quiet. All temperature and energy output readings have been regular.”
The Eco Caravan upgrades the usual Cessna Grand Caravan with Ampaire’s built-in propulsion system of a compression ignition engine and an electrical engine. A battery pack in a physique fairing preserves passenger and cargo capability for the plane.
The Eco Caravan reduces gas consumption and emissions by as much as 70 %. Emissions are close to zero when utilizing sustainable aviation gas. Price of operation is lowered by 25 to 40 % relying on airline route construction. Price per out there seat mile is close to that of driving.
The hybrid-electric plane preserves the vary/payload functionality of the Grand Caravan, and actually can fly farther than the Grand Caravan with eight passengers. Most vary is past 1,000 miles. The Eco Caravan’s vary and cargo hauling functionality is in marked distinction to proposed all-electric, hydrogen-electric and even different hybrid-electric designs.
The Eco Caravan can recharge its batteries in flight or at charging stations on the bottom. As a result of charging infrastructure can be restricted for some years, the power to function unbiased of floor charging is vital for preserving the complete utility of the Eco Caravan.
The Eco Caravan’s propulsion expertise is scalable to bigger regional plane and in the end to single-aisle airliners: Ampaire expects it to be the primary electrified regional plane to enter business service, with certification anticipated in 2024. The corporate plans for it to be the primary in a sequence of bigger hybrid-electric plane that may lead a transition to sustainable aviation, in line with an organization information launch.
FAA approvals: The STC benefit
Like Tier 1 Engineering is with the eR44 helicopter, Ampaire is already working with the FAA to certify the Eco Caravan in 2024 beneath an STC—a supplemental sort certificates.
In each circumstances, the businesses are leveraging some great benefits of modifying plane which might be already FAA-certified for e-flight. The method of supplemental certification for simply the brand new propulsion system remains to be exacting however a lot much less time-consuming and costly that the method required of getting a wholly new plane licensed.
