"V-22 Osprey" has increased the speed by another 37 km / h thanks to updated software




The unique and one-of-a-kind military serial convertiplane “V-22 Osprey”, thanks to the usual updating of on-board software, received an additional speed to the existing speed of 37 km / h.

The company Boeing, which has developed a unique aircraft, has upgraded the software. Thanks to this improvement, the cruise speed of the convertible was increased to 481 km / h. The software has undergone modernization, which controls the angle of attack and the speed of the blades of the V-22 propellers. Such a software update in the near future will still provide an opportunity to increase the lifting power of the engines in the hang mode by 453 kg.

"V-22" thus demonstrated another unique feature that allows the usual updating of a software product, to significantly improve the flight characteristics of the aircraft. Increasing the efficiency of the blades and the engine was achieved only through the modernization of control algorithms. This made it possible, without the need for transportation to the factory, to upgrade the entire V-22 to replace the transmission or engine.

The V-22 Osprey is considered to be a unique device that combines the possibility of helicopter vertical take-off and the rapid flight of an aircraft. The advantage is achieved by turning the engine nacelle with a rotor of a screw with a diameter of 11,6. The V-22 can transport 24's soldiers with full combat gear, 9 tons of cargo in the cabin, 6,8 tons on the outer suspension. The combat radius of the V-22 with the greatest number of troops is 796 km. If we compare it with the technical characteristics of the UH-60 Black Hawk helicopter, its combat radius is less than 600 km with a maximum cruising speed of 278 km / h and with 14 infantrymen in the landing party.

    "Unique" and "only" Americans stole from the Germans

    In 1938, Wesserflug, under the guidance of designer Simon, developed WP.1003 VTOL. The DB 600 was used as the engine, which rotated two screws with a diameter of 4 m mounted on the rotary end parts of the wing. With a take-off weight of 2000 kg, the maximum speed was expected to reach 650 km / h. After the war, under this scheme in the United States built a VTOL V-22 "Osprey".

      Well, why didn’t they stole our? pride not allowed?
      I wonder how a pilot in the 40s could manage this without a computer.

      one-of-a-kind military serial convertiplane. What's wrong? Another serial military tiltrotor was in the studio. But it wasn’t “developed”, “It was expected” and the rotary wing end parts are not equal to the rotary engines.
      and the plane was generally stolen by the Americans.

        Eh youth ...... Did you hear anything about Mozhaysky Aircraft? the Wright brothers flew on December 17, 1903, feel the difference! Feel yourself Russian at last! The best brains in the world!

        Airplane A. f. Mozhaysky did indeed separate from the ground during one of the tests, but after takeoff he tipped to its side and broke the wing. So an event of great historical significance happened - an airplane with a man on board took off for the first time in the world. The details of this event, as well as the name of the tester, are unfortunately unknown.
        In an article by V. F. Naydenov, “An airplane in its historical development and its elementary theory,” it says: “In 1884–85, the airplane was built on a military field in Krasnoye Selo. During takeoff, the airplane tilted sideways and broke supporting surfaces” This message almost literally repeated in the books of V. F. Naydenov “Airplanes”, published in 1913 and 1915, N. Volpyansky “Popular lectures on aviation” (1910), L. 3. Markovich “Aeronautics” (1911) and in others.

    Ours did not stole because the scheme seemed initially technically complex and unjustified
    Read if interested
    Yevgeny Matveyev
    Lecturer at the Academy. NOT. Zhukovsky

    Helicopter Aviation EXplorer Expert

    Flight tests of the car began on March 19, 1989. In 1990, they decided to equip the US Marine Corps with these machines, but the initial order in mid-1992 was reduced to 300 vehicles. The Navy signed a contract to purchase four V-22s and upgrade two existing prototypes, which are supposed to be made lighter and cheaper. The price of one device is $ 71 million, in the future, as manufacturers hope, it should drop to $ 58 million. In 2008, the Pentagon signed a contract for the supply of 167 V-22 Osprey convertibles for a total of $ 10,4 billion.

    However, the June hearings on Iraq’s results “doused”, revealing a whole bunch of V-22 serious flaws. Amid the huge costs of the program, Iraq revealed the unsuitability of its ship-based and low flight performance. The results were so bad that there were voices to close the production and stop the torment of "Osprey".

    Let us dwell on a few points on which "the light was shed."

    1. Low serviceability. The fighting in Iraq was attended by three squadrons of V-22. The average health factor, instead of the promised 87%, was respectively: 68%, 57% and 61%. For comparison, CH-46 and CH-53 in Iraq are over 85%. As of June 23.06.09, 47, only 105 aircraft out of 1998 Osprey purchased by the US Marine Corps since 22 can be used in combat conditions and only 47 of these 21 are ready for military operations (fleet readiness is not higher than XNUMX%).

    2. High cost. Since 1988, R&D, development, testing and evaluation expenses of the program have tripled (from 4,2 to 12,7 billion dollars), and the number of orders has halved (from 1000 to 500). The cost of 1 hour of flight V-22 is 11000 dollars (140% more than the CH-46E).

    3. Performance. Three squadrons flew in Iraq for more than 9800 hours, completing 6000 flights, while transporting 45000 passengers and 1000 tons of cargo. As a result, the average load of a single flight of a rotorcraft worth $ 93 million was only: 7,5 (!) Passengers and 166 (!) Kg. cargo.

    4. Terms of use. Due to the lack of weather radar and an unreliable anti-icing system, the V-22 cannot rise above 3000 m, which is not acceptable for Afghanistan.

    5. Base. The main customer, KMP, cannot use the Osprey in ship-based conditions. Modern US warships can take on board a smaller number of V-22 than its predecessors. Unlike the CH-46, only 4 of the 6 sites on ships of the LHA and LHD class can be used for take-off landing. Moreover, the air flow discharged by the engines is so powerful that it is dangerous for ship personnel (it can easily be dropped from the deck), and the temperature of the exhaust gases is so high that it can damage the site cover in 1-2 minutes of idling. Ground personnel are forced to drag special metal plates for installation under engines on the Osprey deck. Imagine this ridiculous picture of “Barge Haulers on the Deck” that occurs during each taxi. In general, the V-22 has problems with high temperatures, low temperatures, sand, high altitudes and limited maneuverability. With the exception of a small circle of specially selected missions, Osprey is not capable of completing the tasks for which it was intended, and America received half the order at a price three times higher.

    According to American experts, too many mistakes have been made. On the other hand, it is wasteful to close the program, the cost of which reached $ 29 billion. So what to do? Compared to losses in the banking sector and investment funds, this is not the worst loss. On the contrary, we need to turn our attention to other technologies that can increase the flight speed and efficiency of future helicopters within the framework of the necessary carrying capacity.

    In the fate of the "transformable" came another turning point. There were many such turning points, but today, when the new administration is much more critical and less disastrous, Osprey has never been closer to the edge of the abyss. Even if this time it blows and the decision does not happen, each such hearing will inevitably bring the closure of the program closer.

    It became obvious, despite the fact that everyone who worked on the V-22 Osprey deserve all respect and, perhaps, a monument, the program has not paid off.

    I didn’t think that osprey has so many fans winked

    By 1993, when the program was about to turn 12 years old and Bill Clinton became president, the Marines had already spent $ 13 billion on Osprey. But the apparatus was not yet ready for hostilities. In 1991, one of the first V-22 crashed on takeoff due to improper wiring. In the second disaster in 1992, seven people were killed. In 2000, another 2 V-22 crashed, taking 23 marines with them (after which they did not fly for 18 months).
    Helicopter expert Rex Rivolo, who called unscrupulous the decision to deploy the V-22 without ensuring autorotation, refused to give an interview. But in his report, Rivolo noted that up to 90% of helicopters lost in Vietnam were hit by fire from the ground during an approach. About half of them were able to safely sit on autorotations, saving the crews. "All such cases with the V-22 would be fatal."
    V-22 continues to experience problems that are not characteristic of the device, which made its first flight in 1989. For example, in March 2006, the recently refurbished V-22 with three people on board unexpectedly took off on its own, probably as a result of computer problems. After a 3-second flight to a height of 6 feet (according to the testimony of his computer) - or a height of 25 feet (according to the testimony of witnesses), he crashed to the ground with a force sufficient to cause his right wing to be severely damaged, all this for the amount of repair $ 1 million
    Critics have long-standing concerns about poor visibility among pilots, the close and hot space for passengers and the unusually high demands on the machine for maintenance. A failed microcircuit may have led to accidents, after which the V-22 did not fly in February, the same thing happened in June, but the switch could possibly be the cause. In March, the Government Accounting Office (GAO) warned that the Marines are accepting Texas V-22s coming out of the assembly line “with many deviations and failures,” including “several potentially serious defects.” The military’s internal document in June warned that ongoing reliability issues could “significantly” reduce the expected result of Osprey’s participation in Iraq. According to this document, the V-22, built before 2005, are in a state of full readiness only 35% of the time, and newer cars - to - 62%.

        That same year, a meeting on the Tu-22 was held at the GKAT with the participation of the Air Force Commander-in-Chief, Marshal K.A. Vershinin, directors of plants and A.N. Tupolev. The situation around the car was alarming, the flow of complaints from the military did not subside. Vershinin expressed his dissatisfaction with this matter. However, the chairman of the SCAT P.V. Dementiev cut him off rather sharply, saying that "if Long-range aviation needs an airplane, then take what we give with subsequent modifications, and if not, refuse."

        So feel the difference in decision making on the Osprey and Tu-22

      The article may be custom-made, according to other sources on the Mi 30 there was not enough money http://alternathistory.org.ua/proekt-vertoleta-mi-30-rossiya. While we decide whether it is needed at all, the amers are developing a heavy truck based on the C130. Money invested in R&D always comes back in the form of breakthrough technologies. Remember teflon came from NASA.

    Like some children here! Logic - as in an anecdote - Russia wherever birches grow,
    Then the father of helicopter engineering is Leonardo da VINCI, he drew a similar sketch on a helicopter there, and the first aviators - Daedalus and Icarus.

    Before increasing speed, V-22 learned to hang unexpectedly and tightly from a software update. smile

    Versatility is not always a plus, i.e. he can take the weight a little more than a helicopter and can fly quieter than a turbojet aircraft. In addition, we experienced such more 40 years ago.

    Show me at least one, not that the German predecessor was flying, but at least an unfinished model. while there are only fantasies of artists. So do not zvizdet about "stolen from the Germans"!

    Young man, you do not know that the “Mozhaisky plane” could not fly in principle, this was proved by TsAGI in the 80s, so it’s not good to declare Russia the homeland of elephants.

    They discussed everything here ... it’s just not entirely clear how to use the software update to increase the speed by as much as 40 km / h ... and it’s very unfortunate that the MI-30 didn’t bring a very interesting car ... I hope to be resurrected someday ....

    It must be admitted that the Americans are stubborn guys and in most cases they are getting their way, besides they are rich and do not spare money on the defense industry. But there is a positive one in this. Who prevents all others from using and developing their groundwork?
