The RED A03 is a V12 four-stroke aircraft diesel engine designed and built by RED Aircraft GmbH of Adenau, Germany.
Development
In 2012, its unit cost was {{USD|170,000}}.{{cite news |url= https://www.avweb.com/news/500-horsepower-v-12-turbo-diesel-engine-from-germany/ |title= 500 Horsepower V-12 Turbo Diesel Engine From Germany | first = Russ | last = Niles |date= July 29, 2012 |work= AV web}}
The engine received type approval from the European Union Aviation Safety Agency in December 2014 for use in any CS-23 aircraft in both normal and utility categories. It powered the Yakovlev Yak-152 trainer on its 29 September 2016 first flight.{{cite news |url= https://www.flightglobal.com/first-flight-for-yak-152-trainer/121900.article/ |title= First flight for Yak-152 trainer |date= 5 Oct 2016 | first = Dominic | last = Perry |work= Flight Global}} The RED A03 is presented by the ILA Berlin Air Show in 2020 as an application in the aerobatic sector and for defence and security.{{cite web |url=https://50skyshades.com/news/events-festivals/ila-berlin-2020-goes-digital-with-red-aircraft/|publisher= ILA Berlin Air Show |title= ILA Berlin 2020 goes digital with RED Aircraft |access-date= 2025-04-30}}
The engine is proposed for the Hybrid Air Vehicles Airlander 10, a British hybrid airship design, powered by four engines and can be operated with two. In November 2021, an Air Tractor AT-301 made a first flight retrofitted with a RED A03 engine.{{cite press release |url= https://www.aviationpros.com/aircraft/business-general-aviation/press-release/21247807/red-aircraft-maiden-flight-of-retrofit-air-tractor-301-with-red-a03-piston-engine/ |title=Maiden Flight of Retrofit Air Tractor 301 with RED A03 Piston Engine |date= 23 November 2021 |publisher= AviationPros }} The same month, a prototype Otto Celera 500L powered by a RED A03 engine was flown using Sustainable Aviation Fuel.{{cite press release |url=https://www.asdnews.com/news/aerospace/2021/12/16/red-a03-sustainable-aviation-fuel-tests-celera-500l-otto-aviation/ |title= RED A03 Sustainable Aviation Fuel Tests For Celera 500L by Otto Aviation |date= 16 December 2021 |publisher= ASDNews }} On 18 November 2022, Ampaire flew its Eco-Caravan maiden flight: the hybrid electric aircraft uses a RED A03 engine to reduce fuel consumption by 70% on shorter trips to 50% on longer ones. Useful load decreased by 800 lbs, while range improved from {{cvt|1,070|nmi|km}} nm to {{cvt|1,100|nmi|km}}; supplemental type certificate (STC) is targeted for 2024.{{cite press release |url= https://red-aircraft.de/ampaired-had-the-maiden-flight-with-the-red-a03-powered-eco-caravan/ |title= ECO-Caravan maiden flight |date= Nov 18, 2022 |publisher= RED Aircraft}}
