On August 26, 2026, Edinburgh-based flight control manufacturer Aurora Avionics entered into a hardware supply contract with European launch developer Alpha Impulsion.
Under the agreement, Aurora Avionics will design, produce, and deliver an Engine Control Unit (ECU) and a Power Distribution Unit (PDU) for Alpha Impulsion’s autophage rocket engine.
Hardware Specifications and Autophage Propulsion Architecture
The avionics suite provides the core electronic control architecture for Alpha Impulsion’s autophage engine concept. Unlike traditional launch vehicles that carry inert structural tanks into orbit, autophage propulsion systems consume the rocket’s own body structure during flight, converting the vehicle frame into propellant to reduce structural deadweight and increase payload efficiency.
The electronic components supplied by Aurora Avionics perform critical operational functions:
- Engine Control Unit (ECU): Functions as the central command processor, interpreting sensor feedback and issuing real-time actuation commands to manage engine startup, throttling, and safety shutdowns.
- Power Distribution Unit (PDU): Regulates and distributes electrical power from onboard battery systems to thruster actuators, valves, and control sensors across operating phases.
Executive Perspectives
“This is exactly the kind of programme our technology has been designed to support – one where new thinking, advanced engineering and reliable control systems all have to work together,” said Myles Bax, Commercial Lead at Aurora Avionics. “Alpha Impulsion is taking a fundamentally different approach to rocket propulsion, with the potential to reduce complexity and cost while making better use of the vehicle itself. Our role is to give its engineers a dependable electronic backbone for the engine.”
“Developing a new propulsion system requires every part of the vehicle to perform reliably and work seamlessly with the wider engine architecture,” said Marius Celette, CEO of Alpha Impulsion. “The control and power systems are central to that process, and this partnership gives us access to flexible avionics technology that can support the engine as it moves through successive stages of development.”
“By creating avionics that can work across different programmes instead of starting again for every vehicle, we can help companies concentrate their time and investment on the technology that makes their mission unique,” said Oren Smith-Carpenter, CEO of Aurora Avionics. “That is particularly valuable for emerging launch and propulsion companies.”
Development Roadmap and Testing Timeline
Founded in 2022 with teams in France and Italy, Alpha Impulsion will integrate the ECU and PDU hardware into ground-test rigs for initial static fire evaluations. Aurora Avionics will build the units at its Edinburgh engineering facility, configuring the flight software and power distribution pathways to match the engine’s development and flight qualification schedule.
