DENIS FERRANTI METERS LIMITED

Their core work

Denis Ferranti Meters Limited is a specialist UK engineering SME focused on the design and development of high-speed electrical machines — generators and motors — for aerospace and transport electrification. Their work spans the full design chain: electromagnetic architecture, thermal management, power electronics integration, and mechanical coupling systems. In practice, they build and prototype advanced HVDC generators and electromechanical actuators that enable hybrid and electric propulsion in aircraft. Both their H2020 projects were executed under the Clean Sky 2 Joint Technology Initiative, targeting the electrification of large passenger aircraft.

What they specialise in

How they've shifted over time

In their early H2020 work (HVDCGEN, 2017), the company was focused on foundational machine design — electromagnetic modelling, torque-speed characteristics, power electronics, prototype building, and thermal testing of a new generator concept. By their second project (MDD, 2018), the emphasis had shifted from the machine itself toward its integration into a broader aircraft system: how to mechanically decouple it via a clutch, how to prevent fault propagation, and how to manage reliability at the system level. This is a classic maturation arc from component design toward system integration and resilience engineering.

Denis Ferranti appears to be moving up the value chain from standalone machine design toward system-level integration expertise, which positions them well for roles as a subsystem supplier or specialist integrator in future hybrid-electric propulsion consortia.

How they like to work

Denis Ferranti coordinated both of their H2020 projects, meaning they drove the technical agenda and managed project delivery rather than playing a supporting role. The available data shows no recorded consortium partners, which suggests these may have been single-beneficiary SME instrument grants under Clean Sky 2 topic calls — a format common for specialist component developers responding to a defined aircraft OEM requirement. This tells potential partners that the company is comfortable leading technically but may have limited experience managing multi-partner consortia.

The available data records no consortium partners or collaborating countries, which likely reflects the single-beneficiary nature of their Clean Sky 2 grants rather than genuine isolation. Their work is tightly coupled to the Clean Sky 2 programme and its Large Passenger Aircraft platform, meaning their real network runs through Airbus and its tier-1 ecosystem rather than traditional academic or multi-SME consortia.

What sets them apart

Denis Ferranti occupies a narrow but high-value niche: they are one of very few UK SMEs with demonstrated capability to design, prototype, and test high-speed HVDC electrical machines specifically qualified for aerospace use under a major EU aviation JTI. Their combination of electromagnetic design, thermal engineering, and mechanical integration in a single small company makes them unusually self-contained for a firm of their size. For consortia building proposals around aircraft electrification, hybrid propulsion, or aerospace power systems, they bring specialist depth that most generalist engineering firms cannot replicate.

Highlights from their portfolio

• HVDCGEN
  A multi-year (2017–2022) coordinator-led project to develop a high-speed high-voltage DC generator/motor for aircraft, representing the company's core technology platform and their largest investment of EU-funded effort.
• MDD
  The highest-funded of the two projects (EUR 1,069,675) and the more commercially applied one, targeting a specific Clean Sky 2 call for a mechanical drive disconnect — a component with direct aircraft certification implications.
