    So he spells it out, no earlier than 2017 can they substitute helicopter engines from Ukraine.
    And that is assuming everything goes to plan.

    Fantastic news! UEC created "detonation" engines, which are superior to air breathing engines.

    1.) Detonating engines showed a 30-50% reduction in fuel consumption compared to air breathing engines.

    2.) Thrust is increased by 1.5 - 2x that over air breathing engines.

    3.) Detonating engine technology is incredibly flexible, and can be applied to drones, cruise missiles, rocket engines, subsonic and supersonic aircraft!

    UEC creates a new generation of engines for aircraft and missiles

    The developments will be used detonation technology



    United Engine Corporation (UEC) plans to soon begin building new aircraft and rocket engines, which will be used by the detonation technologies.

    Technology demonstrator detonation of subsonic and supersonic engines have already been created. In tests, they showed a 30-50% better specific fuel consumption and cravings compared to the air-breathing, reports RIA "Novosti", citing data from the corporation. The included APC experimental design bureau. AM Cradles proposed the concept of a family of detonation engines for various purposes, including drones and cruise missiles, combined propulsion aerospace aircraft engines and space-rocket systems.


    Detonation engines cover a wide range of speeds, which can be used to create hypersonic missile design which is actively conducted in Russia in recent years. To date, aircraft and rocket engines traditional schemes have practically exhausted the possibility of a significant improvement in their trailer-economic parameters. Therefore, in 2011 in Russia, work is underway to establish a pulse detonation propulsion. In 2013, the OKB. Cradles tested experienced reduced sample resonator pulsed detonation engine with two-stage combustion kerosinovozdushnoy mixture. In experiments performed repeatedly turning on and off of the new engine, as well as the regulation of traction. According to the design office, detonation engine thrust-planes will increase by 1.5-2 times.

    I wonder if this is related to the PAK-FA's engines not needing oxygen to start them up?

    I'm not too knowledgeable about detonation engines. They speak about being superior to air-breathing engines...are they saying they won't need air intakes?

    If that's the case than that should seriously improve a fighter aircraft's RCS, reduction of drag/aerodynamics, as well as increase the space for internal carriage bays for weapons on stealth aircraft, assuming if the air intakes could be discarded.

    Ah no, oxigen is always needed for any kind of combustion, explosion is basically very, very fast oxidation, like couple billion times hastened iron rusting, this is abit plastic explanation and not completelly true but i am trying to make a point here Very Happy They will need air intakes naturally, but not whole time coz there is no continum in fuel burning, but there are gaps between these "explosions" of a sort. I guess intakes will be changed, however they wont be removed.

    "Detonation engines would replace jet engines in airplanes and the gas turbines that run power plants and Navy ships. A set of rotating blades at the front of those engines compresses air, which is then mixed with fuel and combusted in a steady flame. That produces hot gases that do the work an engine is designed to do, whether it’s turning a propeller, propelling a jet, or spinning a generator to produce electricity.

    Improving the efficiency of conventional jet engines has involved finding ways to increase air compression. But the cost and complexity of that approach is making it harder to realize improvements. Detonation engines offer another way to achieve high pressures. In a detonation engine, fuel combustion generates a shock wave that raises pressures to levels 10 times those inside a conventional engine. “It’s like an explosion or a bomb,” says Kazhikathra Kailasanath, a researcher at the Naval Research Laboratory in Washington, DC. “If you burn something in an open flame, the pressure stays the same as the surrounding pressure. The big difference with a detonation engine is going from that to a confined type of combustion, where the pressure goes up and the combustion occurs more rapidly.”

    The most highly developed form of detonation engine, which has been in the works for many years, is the pulse detonation engine, the type GE is developing. Whereas combustion occurs continuously in a conventional jet engine, pulse detonation involves setting off a series of detonations—say, 60 to 100 per minute.

    The Naval Research Laboratory has another idea. It involves the use of a specially designed doughnut-like combustion chamber. One explosion is set off with a spark in one part of the chamber. As the shock wave propagates out from that explosion, the researchers keep it going by feeding in a precise mixture of fuel and air ahead of it. A handful of research groups have tested small versions of the engine that burn hydrogen. And the Navy researchers recently published a paper that shows the idea can work with hydrocarbon fuels like the ones that would be used in a ship, at least in detailed computer simulations. An advantage of this approach is that it produces a constant stream of hot gases, which more closely resembles what’s seen in a conventional jet engine. It’s also simpler, in that there’s no need to engineer a system to create detonations at a high rate."

    I suspect these engines are of a new type.

    The traditional pulse detonation engine is rather old... in fact it is as old as the V1 cruise missile.

    Very simply its engine looks like a ramjet... it is a hollow tube with an open front and rear end for air to flow through. A PD engine however has louvers like a venetian blind over the front air intake. To start the engine fuel goes into the main tube and is detonated... the blast blows the blinds to the front closed so the now contained explosion is directed out the rear of the tube providing a small push forward. When the pressure drops the front venetian blinds open and air is sucked in... fuel is added and detonated blowing the blinds shut and creating another push forward.

    On the real engine the detonation speed will result in hundreds of pulses per second providing quite a bit of thrust.

    the engine is very simple.

    The problem is that I don't think that is what they are talking about.

    During testing with rocket motors it was found that the initial ignition resulted in a significantly higher  power thrust than when the motor stabilised and ran normally.

    What I think they are talking about is changing the way the jet engine is fuelled so rather than smooth continuous burning of fuel in the combustion chamber, they are flicking the fuel on and off so instead of burning it is detonating generating more thrust.

    I'm not too knowledgeable about detonation engines. They speak about being superior to air-breathing engines...are they saying they won't need air intakes?

    they could as easily pump fuel and oxygen into the engine to get controlled detonations without an intake, but it would be much cheaper and much more efficient scooping air up as the aircraft flys along.

    Of course if you make a pulse detonation scramjet engine that can accelerate to orbital speed once you leave the atmosphere the intake could be closed and onboard oxygen could be used to power the engine as a pulse detonation rocket engine outside the atmosphere too...

    Russia to complete import substitution program for helicopter engines by 2019
    Russian Aviaton » Tuesday April 25, 2017 18:53 MSK

    The United Engine-Making Corporation, part of Russia’s state hi-tech conglomerate Rostec, plans to produce 130 VK-2500 helicopter engines this year and complete its import substitution program in 2019, Corporation CEO Alexander Artyukhov said on Tuesday.

    "This year, we have a plan of 130 [VK-2500 engines] and by 2019 we’ll fully substitute helicopter engines from Ukraine," the chief executive reported to Russian President Vladimir Putin.

    The domestically-produced engine is much more reliable in operation and features digital control technology, the chief executive said.

    The VK-2500 turboshaft engine is designed for the upgrade of medium-class Mil Mi-8MT/Mi-17, Mi-24, Mi-14, Kamov Ka-32, Ka-50 and Mi-28 helicopters. Developed in 2001, it is 15-20% more powerful than the baseline TV3-117VMA engine. It features a new digital system of automated regulation and control and has an extended service life. In 2000-2001, the engine completed certification and state bench tests.

    The engines were serial-produced at Ukraine’s Motor Sich Enterprise. Their supplies were terminated after Russia and Ukraine severed their military and technical cooperation.

    MOSCOW, December 27. /TASS/. Russia’s defense and industrial sector has produced 1,200 engines in 2017, including 930 aircraft motors, Vice-Premier Dmitry Rogozin said in an interview with Rossiya-24 TV Channel on Wednesday.

    "We have produced 1,200 engines this year, including 930 for aviation. These are enormous figures," the vice-premier said.

    Russia’s latest PD-14 engine is undergoing trials in a flying laboratory, Rogozin said.

    "We are actually beginning to count from which plane the MC-21 airliner will fly using the Russian engine," the vice-premier said.

    The Russian vice-premier also mentioned the TV7-117ST engine for the Ilyushin Il-114 airliner.

    According to Rogozin, this engine has already been mounted on the Il-114.
