Rim Driven Fan Technology attaches the blades directly to the rim, creating a complete rotor, and moves the electro-mechanical elements to the periphery. The result is a system that is more efficient, quieter, simpler and cheaper??.
RDFs provides a boost in thrust, while the motor's rim distribution enhances torque and cooling efficiency. The lower RPMs and high solidity ratio blades lead to a quieter and more environmentally resilient system. The simplicity of the design also translates to reduced maintenance and certification demands, making RDFs highly scalable and versatile for various aerospace applications??.
Duxion's chairman and CEO, Rick Pilgrim, says that his company is now in the lead regarding the future of electric jet engines.
In 2022, St. John's, Newfoundland-based Duxion Motors Inc. announced that it has entered into a Memorandum of Understanding (MOU) with Dymond Aerospace Inc. to supply 200 patented eJet motors™ for use in Dymond's new fleet of 100 unmanned cargo aircraft.
Under the terms of the MOU, Duxion will supply 20 eJet motors™ per year for ten years starting in 2026 for a total purchase of $500 million CAD. Each eJet motor™ will be built using Duxion's patented technology incorporating a rim-driven motor which utilizes permanent magnet technology in a novel manner to deliver a world class thrust to weight ratio. The eJet motors™ for this application will be capable of producing 8,000+ lbs of thrust, similar to the thrust produced by the engines of 50-passenger CRJ100 aircraft. Each of Dymond's aircraft will be outfitted with two Duxion eJet motors™, powered by hydrogen fuel cells.
