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 US$170,000.
The engine received type approval from the European 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. The RED A03 is presented by the ILA Berlin Air Show as an application in the aerobatic sector and for defence and security.
The engine is proposed for the Hybrid Air Vehicles HAV 304/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. The same month, a prototype Otto Celera 500L powered by a RED A03 engine was flown using Sustainable Aviation Fuel. 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, retaining the Grand Caravan payload capabilities with range improved to 1,100 nmi (2,000 km); supplemental type certificate (STC) is targeted for 2024.
As of March 2023, there were reliable reports of flight testing on a DHC-2 Beaver.
Design
It has twin double overhead camshafts. A marine version was planned for 522 kW/700 hp at 3,900 rpm. The cylinder banks' angle is 80 degrees. The RED A03-200 series is a derivative developed for very high-altitude operation up to 15 km (49,000 ft), with a maximum rating of 460 hp (340 kW) at FL250.
