The Pentagon believes that it understands the importance of creating an adaptive engine for the 6 generation fighter

The US Air Force will be ready to test the "adaptive engine" in 2016 year, if Congress approves the allocation of 1 billion for this program in 2015 year, according to February 28 flightglobal.com.


On February 24, US Secretary of Defense Chak Hagel announced that these investments could be directed to rival companies General Electric, Rolls-Royce and Pratt & Whitney. General Electric is said to have been designing such an engine for the past six years. TRDDF with an adaptive cycle of work (DIC - engine with a variable cycle - approx. "Military Parity") is designed to equip sixth generation fighters and consumes 25% less fuel.

Pratt & Whitney stated that the Pentagon understands how important the DITS program is, and is willing to work on it as part of a sixth generation fighter. Work has already begun.

In 2006, GE and Rolls-Royce North America won a contract from the Air Force Research Laboratory (AFRL) to develop a new generation engine under the ADVENT (adaptive versatile engine technology) program. Pratt & Whitney also submitted its proposal at that time, but was left out of the competition.

General Electric began preliminary testing of its “three-stream engine” in November 2013, with full-scale ground testing due later this year. The engine will be 25% more economical and have 5-10% more thrust than the F136, which was developed by the GE / Rolls-Royce group for the F-35 fighter (this engine lost the competition to the Pratt & Whitney F135 turbojet engine. - approx. “VP ").

Last September, Pratt & Wittney also developed an inlet fan test bench that will be used to create a full-scale engine. The company said that last year, the F-135 fighter jets produced the hottest working gas temperatures ever recorded in a turbojet engine in the F35 powerplant. Increasing the operating temperature allows for greater traction and engine performance. The company has reworked high-pressure turbine blades, which are capable of operating at very high temperatures, the blades themselves are covered with "insulating material."

But General Electric said that working on the ADVENT program gave her a six-year head start over a competitor. The engine has a ceramic low-pressure composite matrix composite components that can withstand higher temperatures than those achieved in previous generation engines, the company said.

        Come on, comrade.
        Do not take too close.
        The photo from the article inspired me:

        A little bit more and a new technological age will come in the mattress.
        The blades themselves are covered with “heat insulating material”
        And then, I cried.
        There was also a film about a boy flying on his own gases.

        No need to get annoyed at the pentagon, just read the article again - it only made me happy -
        Pentagon thinks she understands the importance of creating an adaptive engine for a 6th generation fighter - that is, in fact, the Pentagon does not understand anything laughing

          The meaning of the 6 generation in this case (in the article), a company that loses the tender for the supply of engines, is a burning desire to present its engine, certainly the 6 generation. fellow

        It would be better if the work dragged on indefinitely, and ate as much money as possible, then the program would either be closed or postponed for a later date !!!

      I'm interested in something else. If the f35 has the most high-torque engine in the world, why does it barely overcome the sound barrier?

        Overcomes the sound barrier without difficulty. And the problem is that he is alone.
        In general, just look at the engine thrust PAK FA and F35
        8800 kgf vs 12700 kgf. But since ours has two of them.
        17600 kgf against 12700 kgf. These are the pies.
        At the expense of weight here you can write an entire article.

                Let me give you a post on how it all began to begin.
                The F-35 has a more powerful engine, but the PAK FA and F-22 have two engines, which, despite the weight, gives a great thrust ratio, which makes cruising over sound.

    Such an engine was on La-5 and on Mi-4 helicopters, the engine is good, it flew on this in 1966, but I wonder if we will have DICs or not in development?

      There is hope that domestic engine builders do not stand still. But as far as I understand the creation of the DIC is most likely a distant future. What can be discussed will appear no earlier than in ten years, not to mention serial engines. On the other hand, the fact that GE has been dealing with this topic for six years suggests that they have a clear advantage in time.

          Of course I remember. But what does the news about the development of a new generation engine have to do with the F-35? They put Pratt & Whitney F135 on it, General Electric whose F136 lost took over the ADVENT project and there are certain successes. Or are you trying to say that ADVENT was for the F-35?

      It seems that they began to develop a pulsating RD of a new generation. They promise TTX in general from the realm of fiction.

      around this periodically all the time stamped ...
      The idea of ​​combining turbojet engine + ramjet engine has always been present. Twisted the topic, calculated, estimated ... and discarded as untimely. For example, in relation to the combined SU for the MiG-25 or KR type Granite. I even remember the theme of the "Gnome" ICBM combining RTT + ramjet, the prototype of TEMP-2S / Pioneer / Poplar ...
      There were ideas for space too - we take off on a turbojet engine, go on a ramjet-scramjet engine, then a clean liquid propellant rocket engine ... O5, even because of its exoticism, and mainly difficulties, it was not realized, either with us or with a foreign one (Zenger, all kinds of hotols).

      And so-and-so, at the stages of preliminary projects, settlement - done ... m. and in metal it is partially aggregate-element. But, in relation to realities - no ...
      The reasons are the same - the complexity of the systems for practical use, unsatisfactory performance than individual solutions: turbojet engine separately, ramjet separately.
      From my memory I remember the most advanced NIR-OKR for high-altitude flights and space: a three-four-component taxiway using air, a stored oxidizer and two types of fuel ...

    As I understand it, the fourth generation has not all said yet, the fifth is only being born, and much more has not been created and tested for it, but here the people are creating the sixth right away, in a hurry to cut the budget.
    You can only wish to start immediately and lay the seventh generation!

    For Americans, the funding of ROC under the 5th generation is over, now they need to knock out money under the 6th. One of our teachers at the VKO Academy once said very well: "Soviet 17 dB, this is more than 20 dB in for systems developed in the early 90s and much more than even 25 dB declared in modern Russian developments." After all, the more we promote, the more money will be allocated, therefore, the test methods are adjusted.

    This suggests that Tan has a big problem not with money, but with educated personnel !!!
    Education has done its job, the defense scribe comes slowly !!!!
    Even the abalous attraction of foreign personnel does not solve the problem — less and less scientists are coming to them. They prefer to go to China and India even more. And ours are already not really eager to go there!
    It's like with the F-35 ihnim. If you understand the essence of the problems covered by the ovs, then they just have "children's problems" climb out !!! Which speaks of the low culture of design, and this, in turn, hints at a mediocre level of engineering personnel !!!
    So let them understand further ... I am only for))))

      There is no need to rush in such matters. The USA as pioneers trample the road, it’s cheaper to go after bypassing the pits into which they regularly stumble.
