Swedish electric aeroplane maker Heart Aerospace has teamed up with BAE Systems to develop the battery system for its ES-30 regional electric aircraft.
The battery will be incorporated into an electric conventional takeoff and landing (eCTOL) aircraft.
This is said to support its zero emissions and low noise operations.
BAE Systems Controls and Avionics Solutions vice-president and general manager Ehtisham Siddiqui said: “Our industry-leading solution builds on decades of expertise delivering technologies and systems needed to progress sustainable transportation.
“We are delighted to collaborate with Heart Aerospace on the innovative battery system for its electric aircraft.”
Heart Aerospace’s ES-30 aircraft is equipped with four electric motors, and has the capacity to carry 30 passengers on board with an all-electric range of 200km and extended reserve hybrid range of 400km.
It can fly up to 800km carrying 25 passengers.
The ES-30 battery upgrade roadmap allows for increased usable energy at the same weight, leading to longer flight durations and expanded route options.
Work on the programme will be carried out at BAE Systems’ facility in Endicott, New York.
Heart Aerospace chief operating officer Sofia Graflund said: “BAE Systems’ extensive experience in developing batteries for heavy-duty ground applications, and their experience in developing safety critical control systems for aerospace, make them an ideal partner in this important next step for the ES-30 and for the aviation industry.
“We look forward to decarbonising air travel together.”
