Is it really that more expensive to fly an Il-76 than that of these other smaller planes?  I mean, how much cheaper?

You don't hear much about its big sister though - VK-1600. It was supposed to begin bench test trials late this year.

Wasn't that engine going to be used in the new Il-112 or Il-114 light aircraft?

Specialists of Plakart, a member of RUSNANO Group, in less than 5 months developed a wear-resistant coating for the feather ends of the blades of the PD-35 ultra-large thrust engine compressor, the Group's press service reported.

The new coating is planned to be used on promising wide-body aircraft - long-haul passenger and heavy transport aircraft, including the Russian-Chinese airliner CR929.

The creation of a new PD-35 aircraft engine is being implemented within the framework of the state program "Development of the Aviation Industry". It is based on breakthrough technologies, innovative solutions and new materials.

As part of the support for the implementation of a key project in the field of domestic civil aircraft construction, more than 44.6 billion rubles were allocated by order of the Chairman of the Government of the Russian Federation Mikhail Mishustin.

Plakart JSC is a portfolio company of RUSNANO JSC, established in 2010 to implement a project to create a network of innovative centers for the production of nanocoatings by methods of gas-thermal spraying and surfacing. Plakart performs work both in its own workshops located in the Moscow region, Perm, Tyumen, Nizhny Novgorod, and Naberezhnye Chelny, and at the site of installation and operation of equipment throughout Russia and the CIS.

S.P. Korolev came up with a coating to protect the structural elements of rocket and aircraft engines at extremely high temperatures. Refractory "armor" will prevent the destruction of the internal surfaces of nozzles and combustion chambers, turbine blades and other parts at a temperature of 1500 degrees Celsius.   "This will significantly increase the service life and reliability of rocket and aircraft engines, gas pumping and power generating installations, as well as microgas turbine engines used on unmanned aerial vehicles," explained the author of the project Mikhail Giorbelidze.   In structure, the coating resembles chain mail, consisting of layers of flat scales, which are specially located and fastened to each other. The thickness of all chain mail is less than half a millimeter. Inside the individual "scales" is a protective layer of material that does not allow aggressive components from the environment to penetrate to the engine parts.   After the aircraft engine works out 25 thousand hours (this is the operational life between repair work), specialists check the condition of the coating and the engine element. If necessary, the coating can be applied again and used for another 25 thousand hours. There can be two or three such cycles of use, so the savings, taking into account the cost of engine parts, are tens of millions.     After refining the technology, scientists will create prototypes of the coating for testing
