A&M EDM UAS propulsion system - News release

A&M EDM, precision engineering specialists in the West Midlands are proud to announce the successful commissioning of a proprietary commercial UAS (unmanned aerial system) propulsion system by a non-European client.

A&M manufactured a mock unmanned aerial vehicle fuselage to complete a verification installation of the system. The system travelled thousands of miles in secure packaging to reach the commercial customer and successfully started first time.

This system is uniquely able to deliver up to 3kw of electrical power running on kerosene whilst providing thrust with its low weight, low vibration operation. The architecture provides a bridge between traditional UAS propulsion systems and recent aerospace developments in high electrification, such as vertical take-off and landing, hybridization or range extending systems.

A&M have experience manufacturing rotary engines for a range of customers including projects funded by the National Aerospace Technology Exploitation (NATEP) programme. Over the past five years A&M have developed an in-house R&D project to design, develop and manufacture a complete propulsion system with technical partner TechTeam Developments LLP. As part of the R&D, A&M invested in a bespoke, soundproof engine testing unit, complete with a £40,000 dynometer.

A&M’s system was developed from concept and prototype sales were delivered to the international customer in early 2021. The system generates a total of 10kw has high power density, runs on heavy fuel and is capable of delivering 3kw of electrical power.

Mark Wingfield, Managing Director of A&M said, "We harnessed our engineering design and manufacturing capabilities to create a flexible propulsion system with unique functionality. It is robust, lightweight, compact, multi-fuel operational and very dependable with almost turbine levels of vibration for a wide range of applications.”
