Development
editIn 2012, its unit cost was US$170,000.[2] 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.[1] It powered the Yakovlev Yak-152 trainer on its 29 September 2016 first flight.[3] The RED A03 is presented by the ILA Berlin Air Show as an application in the aerobatic sector and for defence and security.[4]
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.[5] In November 2021, an Air Tractor AT-301 made a first flight retrofitted with a RED A03 engine.[6] The same month, a prototype Otto Celera 500L powered by a RED A03 engine was flown using Sustainable Aviation Fuel.[7] 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.[8]
As of March 2023, there were reliable reports of flight testing on a DHC-2 Beaver.[9][better source needed]
Design
editIt has twin double overhead camshafts. A marine version was planned for 522 kW/700 hp at 3,900 rpm.[10] The cylinder banks' angle is 80 degrees.[11] 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.[12]
