According to technical characteristics, namely: the transportation of oversized cargo weighing up to 250 tons – Mriya and up to 150 tons – Ruslan, these aircrafts are now unsurpassed in the world.
A new engine modification series 3M with FADEC control system, improved acoustic performance and low emission level of harmful substances in order to ensure prospective ICAO standards, was developed by cooperative labor of Ivchenko-Progress SE, which is the developer, and Motor Sich JSC – D-18T engine manufacturer.
