VERTICALLY INTEGRATED
Mission-led propulsion for unmanned systems
Aurora develops compact propulsion systems around the mission—not around the manufacturing process. Our micro gas turbine family is engineered for unmanned platforms requiring a practical balance of thrust, size, weight, fuel compatibility and integration flexibility.
By combining simulation utilising the tools of generative design, CFD, FEA and others, alongside taking a systems engineering approach with digital workflow threads, into printing and manufacturing methods, the design, production and validation of engine builds into an integrated workflow. From that point we can iterate rapidly and retain close control over critical design and manufacturing decisions.

Future Engine Developments
Optimisation and commercialisation of the AU2 and AU4 turbojet engines.
Engine well-suited for high-speed and long-range reconnaissance, long-range precision strike, and tactical UAVs and drones.
Incorporation of the AU-4 as the gas generator to increase thrust output.
Investigate cost-reduction methods, such as direct drive which permits the removal of the gearbox for one-way systems.
Continued development and scalability of the micro turbofan engine to optimise performance for platform integration.
Extremely high thrust-to-weight ratio and relatively low cost make the engines well-suited for small drones and one-way effectors.
