When designing a new family of engines, it is important to confirm technologies and structural solutions first on a single cylinder / compartment, this is the most rational way. DDA - 40 is the first prototype technology presenter. The engine also runs on aviation kerosene and diesel fuel, has a high power density at the level of modern gasoline engines, low fuel consumption at the level of modern diesel engines and high reliability. This particular combination of features is critical for the modern aircraft piston engine.
