Ampaire, a developer of hybrid electric aircraft propulsion, has teamed with Ikhana Aircraft Services to explore modifying Twin Otter airframes to fly with that technology. California-based Ikhana is known for engineering modifications for Twin Otters, including having received an FAA supplemental type certificate for its DHC-6-300HG with a maximum gross weight increase to 14,000 pounds, from 12,500 pounds.
The two companies have launched a NASA-funded study to explore the “electrification“ of the Twin Otter. Under NASA’s Electric Aircraft Propulsion program, the two companies will evaluate various options and produce plans to assess the cost, schedule and risk mitigation for the planned development. The partners’ goal is to be able to put a hybrid-electric version of Ikhana’s 19-seat RWMI DHC-6 300HG Twin Otter. The 1,500 hp/1 MW power specifications of the current aircraft’s Pratt & Whitney Canada PT6 engines meet the criteria for the NASA program.
