The first SSJ100 test flight took place with saber wing tips

28
Yesterday, the first test flight of the Sukhoi Superjet 100 aircraft with the wing tips installed took place in Zhukovsky, reports press office companies "Sukhoi Civil Aircraft".




“The SSJ100 flight with a 95032 serial number with horizontal wingtips installed took 2 hours 42 minutes. In accordance with the flight task, the flight crew performed an assessment of the stability and controllability characteristics of the aircraft in various configurations of wing mechanization. Also in flight were performed modes to determine fuel consumption at various stages. The flight took place in the altitude range up to 11 000 meters, ”the release says.



It is reported that “the configuration of a saber-style tip set on the Sukhoi Superjet 100 was the result of a set of computational studies, engineering and experimental work carried out by the aircraft developer - Sukhoi Civil Aircraft with the participation of the Central Aero-Hydrodynamic Institute named after Professor N. Ye. Zhukovsky (TsAGI) ".



The ending geometry was determined “using innovative methods of three-dimensional optimization based on numerical aerodynamics calculations (CFD), which are a unique development of TsAGI, which is actively used in aviation Russian industries. ”

According to the results of experimental calculations, it was found that the installation of saber tips can simultaneously improve takeoff and landing characteristics and reduce fuel consumption by at least 3%.



Sukhoi Civil Aircraft Company consistently implements the Sukhoi Superjet 100 aircraft improvement program in order to expand its sales markets, number of customers, increase operator satisfaction and maintain a high level of its competitiveness. The introduction of wingtips, which is part of this aircraft improvement program, will, among other things, save airlines up to 5 million rubles per year for one SSJ100,

    But this is GOOD. Now it remains only to compare these endings with "shark fins"

      These tips have been used in civil aviation for a long time. They allow to reduce stall from the end of the wing, thereby increasing lift.

        The endings are yes, but such a "saber-like type" began to be used en masse not long ago. We can say that we keep up to date

          The principle and purpose of the wingtips of various kinds is the same. Yes, I agree, they have been applied not so long ago. This is all calculated for each type of aircraft, more precisely for its wing. On take-off they save fuel. Yes, and during the flight.

        .Allow to reduce stall from the end of the wing,


        In fact, to reduce overflow from under the wing of the wing upwards through the end and the formation of a vortex (decrease in inductive resistance)
        But why do birds need such endings - a mystery to aerodynamics laughing

        So I think so, but since the endings are already patented at a clear angle, they made a compromise, albeit the worst, but their own.

          they made a compromise here, albeit the worst but theirs.


          Well, actually ending up (or down) even though patented, though not - is also a compromise. They reduce inductance, but add a profile. In addition, strength requirements are increasing for the wing. And then - it is not necessary to bend them up or down - the increase in the range with a narrowing tip is enough - the effect is the same. This is beneficial when there is no way to increase the scope of the requirements of the dimensions. Screws are good - the diameter is a bit smaller. But in general, if you see without endings - this does not mean "worse." It means that the wing was initially correctly chosen (more precisely - guessed wink ) It's just a way to “modify the file” already stuck wing, when doing new is too expensive.

    Even if the fuel consumption remains the same, the improvement of the water supply index is already a plus.

      More engines from the PD series

      A family of aircraft engines with take-off thrust from 8 to 18 tons is planned to be created on the basis of the PD-14 gas generator, Alexander Inozemtsev, general designer of Aviadvigatel (Perm), told Interfax-AVN.
      “The most powerful engine in the PD-14 family will be the PD-18R modification. This engine is designed for heavy passenger and transport aircraft of the IL-96-300 / 400T type, ”the general designer said.
      According to him, for the engine PD-18R the highest take-off thrust in the PD-14 family will be 20 tons. “This is the biggest craving in this family,” A. Inozemtsev noted.
      However, he did not rule out that in the future it is possible to increase traction. “So far, according to our calculations, this gas generator is capable of providing traction up to 20 tons. To get takeoff thrust of more than 20 tons, another gas generator of a greater dimension is needed, ”A. Inozemtsev said.
      It was previously reported that PD-18R (P-reducer). can be used on Tu-214, Il-96-300 and Il-96-400T aircraft. According to experts, the efficiency of the PD-18R will be about three to five percent higher than that of the PD-14.

        PD-14, PD-18 have a resource before overhaul of 200000 hours. Modern samples of this class have a resource 8-18000 hours.

    Wow, there seems to be a small addition, and such savings that undoubtedly give him an additional plus, airlines will only be happy about this.

    And for me, it is better to devote all efforts to finalizing the MS-21 and IL-96-400 ... The superjet for so many years has not really met the expectations in both export and domestic routes.

      Well, it's you Andrew in vain! It was initially clear that it would be so difficult for him to break into the world market, but he will slowly make his way, despite the dirty backstage intrigues of his competitors.

        And religion doesn’t allow him to enter the domestic market? How many Superjets do our airlines use?

              The problem is that a very large number of the same B and A are used. But they are not competitors for the SGS (except perhaps the A-318 and then with a reservation). The main competitor of the SSJ in the market is the Bombardier Regional Jet and Embraer EMB 190, as well as turboprops of various stripes.

              The market for short-haul jets (not turboprops) is quite small, compared to medium-haul jets, even insignificant. All hope for MC 21

    Winglets have added to a superjet? Well, fashion is now on them. They really save fuel like a plate on the hood of your car. Wings are not made just like that. Judging by the photo, it's just for beauty. Standing winglets just can't be built. at the wingtips of SUPER it’s a laugh through tears. What they write is a tribute to fashion. Winglets are a rather complicated situevina. And it’s developed for each model. And then they stuck a record ... wassat

Judging by the meaning, this is only for the implementation of the plan. A good comment will not be written. The one above is just a spoonful of childhood surprise. Just an example from the training manual. Writing a comment needs to be comprehended. And do not write haphazardly. And then it came up ... stop

        Give birth to an idea. For a person who develops winglets for MS. I will throw your opinion to him. Only, maybe then you will fall into the sewers. Do not go there where you do not rummage.

      Incidentally, it was precisely the “winglets” that were initially worked out. But modeling and blowing in the pipe showed that it is “these laughter and tears” that give the greatest gain on this wing. Can you prove the opposite?

    Like it or not, but the plane has occupied its niche, and is developing. What pleases. If only, the sanctions were not crippled. Still, it is very troublesome to certify with the new one according to the new one.

    that's interesting, but immediately it was impossible? moreover, winglets were still used on the su-80, and there isn’t one “classmate” modern without them. is it own shortsightedness or did the "assistants" from the Boeing try?
