AEMTA is a collaboration aimed at building the UK’s capability in supplying the aerospace industry with electric machines over the next few decades. Headed by leading aerospace supplier Safran, the project brings together the potential supply chain with Newcastle University’s Electric Power (EP) Research Group.
EP is internationally recognised as being able to design and deliver innovative electrical machines for use across the aerospace, automotive, renewable and white goods sectors. The project has set demanding specifications for class leading performance for which EP has delivered feasible designs. Newcastle’s workshop are currently assembling a bespoke machine as part of the high performance work stream, the likes of which have not been demonstrated anywhere in the world.
Newcastle’s project lead Dr Nick Baker adds that “This type of collaborative project combines Safran’s market knowledge with Newcastle’s unique research excellence to deliver class leading machine performance. Most commentators are expecting a growth in the electrification of the aerospace industry and AEMTA joins the market pull with the ‘technology push’ of research coming out of Newcastle”

This work package investigates the design, development and construction of a high torque density electric motor. This motor will provide a potential fuel mass saving of 396 kg per flight in a medium sized, twin engine, passenger aircraft, equating to a saving of approximately 158 tonnes of CO2 annually. However, this benefit is sensitive to the mass of the proposed motor: too heavy and the fuel burn during the flight cycle will negate any potential savings made, too little active material and the machine will saturate early, which will limit torque production. Moreover, a low mass solution will be thermally challenged. Therefore, it is necessary to conduct and in-depth design study around the key areas of torque density and thermal performance before producing a prototype machine.
