Tehmash creates a new adjustable projectile

21
Specialists of the concern "Tehmash" develop the concept of an adjustable projectile caliber 152 mm for artillery systems, reports TASS a message from the deputy general director of the enterprise, Alexander Kochkin.



According to Kochkin, after the shot, the projectile will fly along the usual ballistic trajectory, but closer to the target, it will begin to adjust its flight at the expense of its own control system.

He noted that it is quite difficult to implement a control system in such ammunition due to powerful dynamic loads - the projectile experiences them at the time of the shot, while rotating in the bore and then in flight. Optics in such conditions (at rotational speed up to 30 ths. Revolutions per second) will not work - the picture will be blurred. Therefore, the development and is considered difficult, added Kochkin.

The general director also said that the designers are considering several ways to adjust the flight at the final stage, including the aerodynamic surfaces on the fuse or the use of jet miniature engines.

At the same time, according to him, corrected ammunition should occupy an average price niche - more expensive than conventional projectiles, but cheaper than Krasnopol’s type of guided ones. He added that this development is not incorporated into the state armament program, so the corporation will maintain it at its own expense.

The agency recalls that the 1980-mm adjustable projectile, known as the "Centimeter", was already created in Russia for the 152 years. It was used by Soviet troops in Afghanistan. The adjustment of its trajectory began meters behind 600 to the target highlighted by the laser designator. The flight was corrected by the inclusion of jet engines.

    Why bother if there are missiles?

      Missiles are many times more complicated and more expensive than a projectile with jet-pulse laser correction for stationary or with predictable movement of targets.

        Thank. But in relation to what will be more expensive, it is not yet clear.

        As an option, -If there is a possibility of correcting the projectile with rudders, it means that rotation when fired for stabilization is no longer necessary, because rudders are also used for stabilization without rotation, as for a "smoothbore" shot. Many problems disappear and the correction in the final section is performed with the same rudders. ... Shoot the projectile with a pushing pallet with leading belts (to close the breakthrough of gases) with a center stop of the projectile on a hinge, without transferring rotation ...

    how will the projectile "know / see" the target? The Americans bombed Yugoslavia with conventional bombs with a slight modification + gps .... but a shell? If anyone in the world has such shells at all?

      so what's the problem? in the Russian Federation, they are developing adjustable (guided) projectiles for the 57-mm cannon (in the smaller caliber 37-40 mm, developments are underway in the West). GPS modules for adjusting the trajectory in artillery shells have been used for several years (M982 Excalibur as an example). the only thing that does not suit the customer is the price ... although if you take the "cost of performance" of the task, you can also argue
      so in Syria the Russian aerospace forces are basically beaten conventional bombs with a little alteration request again, it all depends on the ratio of the value of the goal and the spent funds for its (goal) defeat

      There are such shells. In Russia, as it was written, "Brave", "Centimeter" and "Krasnopol". In the US Army - "Excalibur".

      If at all who in the world has such shells?

      Such a train of thought, although characteristic of the average. (no offense) to a Russian citizen [whether or not someone else] is fundamentally unproductive. This thought follows on the fly reformatted into something else: "It's good that neither in the media, nor intelligence did not find similar developments in" probable colleagues "- we will be the first and for a long time - the only ones. There will be a handicap of time for finishing and for more distant ideas."

      Not like a shell. Just now infa slipped that the Americans did a controlled sniper bullet. And there the caliber is good if 14 mm.

    "at a rotation speed of up to 30 thousand revolutions per second"
    I understand what I wrote?

        Okay, I’ve lied slightly at 14 km / s of a single point on the circumference of the projectile ??? in my opinion a bit too much

    It would be better to create an adjustable shell for a 125 mm tank gun, so that tanks could work on purpose at a distance without entering the ATGM coverage area.

      The tank has "Kitolov" as an example. Just as you imagine, shooting a tank from closed positions with an adjustable projectile, who will correct it? Tanks work with direct fire. There is a video from Syria, from an unmanned aerial vehicle, which corrected such shells, domestically produced.

        Kitolov - a complex of guided artillery weapons. Caliber, mm 120 or 122.

        What kind of Russian tanks have such a caliber?
        Guided missiles Cobra, Reflex, Invar are used on tanks.

    Artillery shells with RCIC technology "should" cost less than Krasnopol with "the same" GOS ... But RCIC technology will especially show itself when creating a cheap GOS ... Although ... I think that the impulse correction technology in its own time missed its chance to become the # 1 control system in the "field" of cheap (!) adjustable artillery shells! Mass production of "relatively-relatively" cheap miniature gyroscopes; and hence the "whole" INS ... miniature piezoelectric motors (and other miniature stepping motors) promoted the ACAG (e) -technology to the main (and successful) competitors of the pulse correction technology ... And the emerging and rapidly growing popularity on electronic toys. in particular with "inertia" ...

      that the technology of impulse correction at one time missed its chance to become the control system number 1 in the "field" of cheap (!) adjustable artillery shells

      Because of the expensive LGSN.
      Against the background of its amazing cost, the difference in price between the adjusted and the managed was practically not visible, but at the same time the managed had an order of magnitude more opportunities.

    Therefore, development is considered difficult, Kochkin added.
    ... and not cheap, I suppose ...
