The speed of the Russian perspective helicopter will exceed 400 km / h

73
A promising combat helicopter in June will make the first flight at speeds up to 450 km / h, reports RIA News a message from Andrei Shibitov, deputy general director of the Russian Helicopters association.




“The works are not suspended, they are in full swing. We decided to divide this program into two parts, the first - the research. The flying laboratory has already made the first flight, now it is already preparing to make a flight at that speed which is planned according to the program ”,
explained Shibitov.

He noted that "today the maximum speed of modern helicopters is approximately 300 kilometers per hour."

The holding plans to "exceed this figure by almost 50 percent," the deputy head said.

He clarified that “the technical assignment and design of the high-speed helicopter project is to be determined by the Ministry of Defense of Russia”.

      Faster than a helicopter - faster than rescue or evacuation operations.
      Not a superfluous development.

            A tiltrotor can perform helicopter functions only in terms of take-off / landing.
            As a transporter, he is not bad, but as a combat helicopter, it is almost completely useless.

              /// If some "all tired" had not destroyed the USSR in their time and did not try to destroy all defense industries together with specialists, then there would be well-developed combat vehicles. And so people worked under the constant pressure of dismissal and the threat of closing their enterprises, and actually at their own expense, so you would not have thrown unnecessary liberal hysterics here. Moreover, the armament already has a pretty good combat vehicle Ka-52. And if we still modernize and adopt its "Shock" predecessor K-50, then until the appearance of new promising models in the ranks, this niche will be reliably closed.

      Mi-28. His sore spot is the main gearbox ...

      This question is well covered here: Nails in Mi-28Н http://tehnowar.ru/40836-gvozdi-v-mi-28n.html Here is an excerpt from there
      If you exaggerate everything that happened around the gearbox, we can only say that it was too lightened, hoping that it would be justified. But any mechanism has such a concept as strength and resource - this is exactly what the new BP-28 gearbox lacked. In short, when in the 1982 year the first Mi-28 took off, there were two TV3-117 engines with a total power of 4400 hp. and the main gearbox, which let through (think about it!) only 3300 hp Take away from here the 12-15 percent of the power that goes to the tail rotor, and it turns out that to create lift on the latest Mi-28, it took only 2800 hp, while the Mi-24 helicopter (created in the same design bureau 13 years earlier) had a much more serious power in 3700 hp to create lift.

        Yeah, it’s lit, it’s lit, but there are no productive machines for machining titanium. And by casting and stamping you will do far from everything. Of course, there are easy reasons to be proud of something like Vf-33, but the Chinese counterparts are already the future, not to mention others ...

            Slightly late for your terrible secret, but just in case, I will unsubscribe. Bravo domestic tool for processing titanium and alloys, that's just what to process. Details of a certain weight (small) are not manufactured at all in Russia, in view of the specificity of the technology, especially grinding. They are made, for example, in China, on machine tools in liquid media and even under vacuum. If you show the Russian analogue, I have a bubble of cognac.

          The maximum speed of the serial helicopter “Link AN.Mk.9” is 260 km / h, cruising cruising speed: 140 km / h. The 400 km / h speed was obtained in 1986 on a specially prepared record non-serial extremely lightweight modification, with an engine increased by 40% power and with special speed profile blades.

      The resource of the reducer was counted on a life time in battle of about 20 minutes - I was told this back in 2001. on "Rosvertol" in the design office. That is why our combat helicopters did not take the market away from the Westerners, with the resource in trouble. High-speed helicopters in the army, but not needed in the civilian sector? Rescuers, local aviation, doctors. Yes, in our north without helicopters trouble. And we do everything for export, as if we don't need it ourselves. They say correctly: For everything to go well with the economy in Russia, one interfering factor must be eliminated - the population (this is from the point of view of our economists from the government). But we have not a territory, but a country and not a population, but a people!

        There is no need to reinvent the wheel, we have an excellent basic Mi-8, how many thousands of copies of it and its modifications are working around the world both in the military and in civilian performance. How many years it flies and it is not known when it will finish. And by the way, even the striped ones buy it on the sly, allegedly for others. Therefore, there is no need to rush, you have a good example of the F-35, one is wrong, then another. This is a very serious matter, the development of a qualitatively new machine, and it takes 10-15 years. For example, the MiG-29 made its first flight in 1977. And the Mi-28 was in a hurry to release it as opposed to the Alligator, but these are temporary difficulties, or they will bring or radically change something. The war has shown that it is better to have the T-34 and KV than a bunch of different tank models.
        So now I look, almost every day, one thing, then another. You can develop, the main thing is to choose what you need in the series.

      And what's funny? Is this a US Air Force drill helicopter or a massive civilian unit? The usual prototype of the company that founded the Russian engineer émigré Sikorski. Helicopter on coaxial scheme, which was mastered in the USSR at the beginning of the 80-s, and even earlier.

            The idea of ​​coaxial rotors originates with Mikhail Lomonosov. He developed a small model of a helicopter with coaxial rotors in July 1754 and demonstrated it at the Russian Academy of Sciences.

            In 1859, the British Patent Office received the first Henry Helicopter patent for its coaxial design. From this point of view, coaxial helicopters are designed into fully operational machines, as we know them today.

            Two pioneer helicopters, the Corradino D'Ascanio built by "D'at3" in 1930, and the generally more successful French mid-1930s Laboratoire gyrocopters, both use coaxial rotor systems for flight.

          This is called a "tiltrotor" and they never developed the maximum speed declared, due to the appearance of a "flutter" on the blades during acceleration, after turning on the "cruise" engines. Simply put, the HB (main rotor) becomes a "burden" in strength and, accordingly, ceases to perform its main function of a "movable" wing. All you show is working prototypes. And the video above is generally a "gyroplane" with coaxial HB, but not even a "tiltrotor", let alone a helicopter. When I was studying at the school, a teacher in Aerodynamics said that it was theoretically and mathematically calculated that a helicopter could fly at speeds of more than 500 km / h.
          By the way, the author is wrong at the Mi-24 maximum speed of 320 km / h and the Mi-26 350 km / h

          There are two big differences between (1) the principal invention of the coaxial circuit and (2) its design and technological mastering, bringing it to the required levels of reliability and resource and putting it into mass production. It was the second that was implemented in the USSR and Russia and almost never implemented in the rest of the world. It is a fact. Mass production of coaxial helicopters, including combat ones, has not been mastered anywhere else at a similar level, except in Russia. Why argue who invented and previously patented the coaxial circuit? Personally, this is completely indifferent to me, moreover, I would prefer that it is another state, like the United States, at the expense of its taxpayers to spend colossal money on R&D of various projects and at the expense of its own funds to prove their prospects and practical applicability, and also incur losses on those projects that turned out to be unpromising (and there are at least 70% of those, according to my estimate, and there are vivid examples of such "golden nails" that cost the US budget enormous money and ended in nothing). And then a country like Russia, using US research, chose fundamentally successful developments and made its own analogues. Which, by the way, are often superior to the original.

      Sample X-2, received serious comments on the operation of the gearbox and transmission.
      So far it has not been possible to solve.

      Sikorsky has closed the X2 high-speed helicopter development program. The last flight of the prototype X2 made 14 July 2011 of the year - on this test machine recognized as completed. All technologies and developments tested on X2 will be used to create the S-97 Raider helicopter, developed as a high-speed reconnaissance vehicle for the US Army.

      The X2 trials lasted six years from 2006 to 2011 and cost the company 50 million dollars. During this time, there were absolutely 23 experimental departures, during which the prototype spent 22 hours in the air. During one of the flights, it was possible to develop a speed of 468,6 kilometers per hour (253 knots).

      The new S-97 Raider combat vehicle in which new technologies should become serial is being created in the fall of 2010 in two versions - reconnaissance and strike. S-97 is being created as part of a tender announced by the Pentagon and is due to make its first flight in the next four years. If the tender is won, the Sikorsky helicopter will replace the Bell OH-58D Kiowa Warrior helicopter currently in service with the US Army.

      S-97, according to the plans of the developing corporation, will be able to freeze at a height of up to 3000 meters, while maintaining the temperature at 33 degrees Celsius and develop a cruising speed of 370 km. per hour (200 nodes).

      How didn’t he go? Based on it, the S-97 Raider will compete with the V-280 Valor. To replace the UH-60 Black Hawk. But it seems to me that they will leave both too interesting technologies.

    The problem of a high-speed helicopter is the supersonic barrier, which begins to overcome the ends of the rotor blades when the helicopter exceeds speed in the region of 330 km / h. Therefore, high-speed helicopters have pushing propellers, and the circuit is papillary to balance the loss of lift of the rotors. The gyrocopter alone exceeded a speed of 600 km / h, but this is not a helicopter, and its wings are not small there.

      The Americans in the 50s tried to attach a supersonic propeller to a fighter. The result obtained on the XF-84H prototype shocked ... with its sound. In history, this aircraft went down as "Howling Thunder" ... There was an article about it on the site.
      This year, in the Kremlin, a group of mathematicians was awarded who created a mathematical model of the rotor for an ultra-high-speed helicopter. And already in June, the race for the ghost of speed! Our Mi-24 in a record version, held the palm 11 years. The record was set in 1975, -368km / h. We are waiting for new VICTORIES !!!

      Mi-26 top speed of 350 km / h. But in principle, you are right, with just one correction, only 4 blade profiles are currently designed, calculated and working! But everything flows and changes, new materials and methods for studying the physics of air flow appear. Therefore, the appearance of new or new high-speed profiles is quite possible.

      I wonder what is the speed limit for machines with an overhead propeller?

      What is the diameter of the screw? what

      For a helicopter of classical design, the lifting force of which is limited by the capabilities of the retreating blades, a technological speed limit is reached, approximately equal to 400 km / h.


      The technological limit of the speed of a helicopter is determined by the difference in the speed of the advancing and retreating rotor blades relative to air. The speed of the helicopter is added to the speed of the advancing blades and is subtracted from the speed of the retreating blades. If the angle of attack of the blades on the advancing and retreating sides of the rotor remains unchanged, the lifting force on the advancing side will be much larger than on the retreating side, and the helicopter will roll over. The swashplate of the helicopter of the classical design is designed to compensate for this difference by cyclically reducing the angle of attack of the blades on the advancing side and increasing on the retreating side.

      In the coaxial Sikorsky X2 scheme, the swashplate does not carry compensatory functions.

      Sikorsky ABC (Advancing Blade Concept)




      When the tips of the helicopter blades approach the speed of sound, the resistance to rotation increases sharply. This could be the next speed limit for a helicopter.

      probably, as in the coaxial Sikorsky X2 scheme: the swashplate does not carry compensatory functions. Bearing screws are not responsible for creating horizontal traction and compensate for the mutual desire for roll, so the need for a cyclical change in the pitch of the screw disappears.
      The lifting force is determined by the power of the advancing blade, and is not limited by the capabilities of the retreating one, in comparison with the helicopters of the usual schemes, it will be able to maintain height at a lower speed of rotation of the main rotor.
      The lifting blades do not create a "push" strength. Only lifting.
      Something like:






      Fact that the horizontal flight speed is not determined by the rotors and the lifting force is used as efficiently as possible, allowing the rotors to rotate very slowlyand a helicopter to fly very fast.

      next helicopter speed limit: about 550 km / h

        These are AUTO FATS with all the disadvantages regarding helicopters. And the very first IM needs a RUN for takeoff of at least 100 meters !!! and even more it all depends on the download. For landing, you also need, though much shorter, but still a RUN. And these are the main advantages of using a HELICOPTER. I put my AS-350 in a "well" 30 meters in diameter !!! in the forest, around 15-25 m trees. If you plant at least one of these "pictures" there, it will be a MIRACLE wink

    In my opinion, helicopters have already reached the technological limit and we are trying to catch up with global developments instead of focusing on more promising platforms. For example: all subsonic devices are divided into 3-4 classes and all in the format of convertiplanes. There is full coverage of all cargo and shock tasks in the speed range 0-850.

    probably the maximum speed is not the only indicator by which the effectiveness of such a complex product as a helicopter is evaluated. he still needs to accelerate to this speed and maneuver it will be more difficult for him, here he needs to determine priorities for assessing the combat effectiveness of existing models.

    If it were not for Messrs. Gorbachev "HMS" and Yeltsin "Ebn" with a team of liberal reformers and overseas curators, we would have had our own high-speed helicopters and even tiltrotors. Only in our country, in view of the prevailing realities, all promising developments have remained on paper or in the form of experimental models, and in the countries of overseas curators and their vassals, they have been implemented into working prototypes. Fortunately, now the situation has changed radically, and if in the future all this liberal pack is not allowed to come to power, we will still have everything. And a lot is already there, but not for public access and discussion, for there is still a lot left of the liberal government, sent in prisoners in the localities. But there were a lot of projects:
