In 2010, this company presented a new aeronautical Diesel engine, which has already been successfully tested in flight. It is a V12 and is known by the reference RED A03.

“RED A03”

-This engine is water cooled, and it has the 'common rail' system for fuel injection that is used in car engines.

-It has reducing gear and gives 500 CV at 3,900 crankshaft rpm.

From Appendix 9: This is Rakhlin Engine Development. In addition to the V12 -AO3- which is already discussed in the main text, this engine has been improved and now there is also the V6 version with reference AO5.

"The AO5, shorter, V-6"

-Both engines run on Diesel to use Jet-A1. The AO5 gives 212 hp (300 kW) while the AO3, V-12 gives 368 hp (500 kW).

From Appendix 11: This company was founded as Raikhlin Engine Development (RED) in 1995. In 2008 RED Aircraft GmbH is launched. Under this name they started to build the AO3 engines.

-On their website the AO5 is not mentioned. But on other sites on the internet it is. Probably it remained a prototype or was not officially taken into production.

-For the AO3 there are several versions.
