About

Advanced Innovative Engineering UK Ltd is a defense subsystem manufacturer based in Lichfield, United Kingdom working in unmanned systems.

Advanced Innovative Engineering (AIE) is a UK company based in Lichfield that develops, designs, manufactures and tests Wankel rotary engines for aerospace, UAV, marine and automotive applications. Its products include air-cooled and liquid-cooled engines in the 5 to 120 BHP range, using its patented Compact SPARCS cooling technology, which uses pressurised combustion blow-by gases to cool the rotor and engine core. AIE's engines are marketed for UAV and UAS propulsion, including heavy-fuel and multi-fuel operation (e.g. JP-8, JP-5, Jet-A1). The company has worked under a contract with the U.S. Army DEVCOM Army Research Laboratory on a UAS propulsion system and has conducted flight testing with the U.S. Air Force Research Laboratory. AIE operates an AS9100D-certified quality management system at its single UK facility, offering consultancy, design, prototyping, development, testing and manufacture in-house. It also participates in research with Brunel University London and Mahle Powertrain on biofuel and hydrogen rotary engines, funded partly under the EPSRC Prosperity Partnerships programme. The company is a member of the Midlands Aerospace Alliance.
