What Advanced Innovative Engineering does

Advanced Innovative Engineering (UK) Ltd (AIE), founded in 2012 and headquartered in Lichfield, United Kingdom, designs and manufactures Wankel-type rotary engines and proprietary cooling systems for aerospace, automotive, marine, and power generation applications. The company sells five core engine models ranging from 5 BHP (40ACS) to 120 BHP (650S), all built on patented SPARCS (Self-Pressurising-Air Rotor Cooling System) or Compact SPARCS liquid-cooled technology, with the CREEV exhaust expander module offered as an add-on for range-extender applications. AIE's engines support multi-fuel operation across gasoline, AVGAS, JP5, JP8, Jet-A1, kerosene, diesel, natural gas, and hydrogen without hardware modifications, and are designed for high power density (e.g., 40 BHP from a 22 lb core) and 500+ hour time-between-overhaul service intervals.

AIE operates a B2B enterprise sales model, engaging directly with defense contractors, UAV integrators (Textron, IAI, Leonardo, Schiebel), aerospace primes, automotive OEMs (Westfield Sports Cars, and via Mahle Powertrain partnership), and government research bodies (U.S. Army DEVCOM ARL, UK MoD Watchkeeper programme). Revenue is generated through custom engine sales (hardware), engineering and development services (professional services from concept through testing at its single Lichfield facility), and collaborative R&D partnership funding (e.g., EPSRC Prosperity Partnerships, Horizon 2020). Pricing is quote-based and not publicly disclosed. The company holds AS9100D, EN 9100:2018, and ISO 9001:2015 certifications, is a member of the Midlands Aerospace Alliance and Make UK Defence, and reports cumulative operational track records of millions of flight hours across UAV platforms. Recent strategic emphasis is on heavy-fuel engine development for tactical UAS (225ACS Gen 5) and hydrogen combustion propulsion for hard-to-electrify transport sectors.

Core offering

Advanced Innovative Engineering (AIE) designs, develops, and manufactures compact Wankel-type rotary engines ranging from 5 BHP to 120 BHP for UAV/aerospace propulsion, automotive hybrid range-extender, and marine applications. The company leverages its patented SPARCS and Compact SPARCS closed-loop rotor cooling systems to deliver multi-fuel (gasoline, AVGAS, JP-5, JP-8, Jet-A1, diesel, hydrogen) engines with high power-to-weight ratios. AIE also provides full custom engineering services — consultation, conceptualization, prototyping, design, testing, and low-volume manufacturing — from its single Lichfield, UK facility.

Product overview

Advanced Innovative Engineering (AIE) designs and manufactures Wankel rotary engines for UAV propulsion, automotive hybrid applications, and marine use. The product portfolio centers on five engine models (40ACS, 80S, 225CS, 225CS-018, and 650S) ranging from 5 BHP to 120 BHP, all featuring AIE's proprietary SPARCS or Compact SPARCS cooling technology. Supporting these core engines are technology modules including the SPARCS air-cooled rotor cooling system, Compact SPARCS liquid-cooled variant, and CREEV exhaust expander for energy recovery. The engines are designed for multi-fuel operation (gasoline, AVGAS, JP-8, Jet-A1) and target markets including aerospace (UAV/RPAS), automotive (hybrid range extenders), and marine propulsion.
