Tier 1 Engineering conducted the first flight of an all-electric Robinson R44 using the MagniX electric propulsion unit (EPU). The three-minute flight took place June 4 at the Los Alamitos Army Airfield in Southern California. Tier 1 integrated its battery system and the MagniX EPU on the helicopter, which is being developed for Lung Biotechnology PBC, a biotech company that is focused on alleviating the shortage of transplantable human organs.
"This historic flight, of an all-electric helicopter with a certifiable electric engine, was an important step towards obtaining aircraft certification. We are excited to expand the flight tests to greater distances and demonstrate safe, reliable all-electric flight," said Tier 1 president Glen Dromgoole. Tier 1 is working with the Los Angeles FAA Aircraft Certification Office (ACO) on the “e-R44” project to obtain a supplemental type certificate for the conversion program. Lung Biotechnology PBC plans to acquire a fleet of the aircraft to fly transplant organs.
