Dangerous competitor "Coalition-SV". High-speed "carrying cone" with air defense capabilities

28
The 2018-th International Exhibition of Arms and Technologies “Eurosatory-26”, held in June 2018 in Paris, was marked by an unprecedented abundance of concepts of promising naval, anti-aircraft missile and artillery presented to the public. As it turned out a little later, one of the most unusual and attractive for the customer specimens announced during this event was the demonstrator of 155 mm Solid Fuel RamJet, an ultra-long 155-mm controlled projectile equipped with a rocket-ramjet engine. with a solid gas generator open. This original decision of the Norwegian and Finnish experts, also considered by our specialists from the Tula “Scientific and Production Association“ Splav ”to update the ammunition sets of the domestic 152-mm self-propelled guns Msta-S and Coalition-SV, could not help us to prepare the article : a comparative review entitled “Whose“ god of war ”will receive a bonus on European theater? Race of unique shells ", which can be found on the" Military Review "in the"WeaponFor June 20 2018 of the year.





In the above material, we examined in detail all the advantages and disadvantages of “rocket-direct-flow” artillery shells and were able to come to the following conclusions. Thus, a sufficiently long period of operation of a ramjet (burning out a solid propellant gas generator) allows, firstly, to maintain a high supersonic flight speed in 3200 — 3400 km / h, both on the cruise trajectory and on the final part of the trajectory, and also provides greater kinetic energy with the defeat of the target to compensate for the reduction in the weight of the projectile's combat equipment), secondly, to achieve the firing range at 80 — 120 km, which ensures complete mastery in the offspring of the «Nammo» of being in mass production by US guided artillery shells family M982 «Excalibur», not to mention the usual 155-mm high-explosive shells or rocket-assisted projectile.

But even despite the fact that the unique properties of this projectile caused a lively interest of representatives of the US Marine Corps, representatives of the US defense department did not focus on the ambitious Nammo project and finance it, which is why the fate of “155 mm Solid Fuel RamJet has remained vague. And the reasons for this are quite trivial. First of all, this is the need for a radical miniaturization of the radio electronic and electromechanical elemental base of the “smart projectile” to separate the internal volume under the contours of the rocket-ramjet engine and the compartment with the warhead. Naturally, such miniaturization will complicate and raise the cost of manufacturing the “critical” components of the projectile, bringing the total cost of the product to 250 — 300 thousand dollars, which the Pentagon is unlikely to suit even taking into account the 2,5 times lower cost than the projectiles of the closed LRLAP project. Secondly, this is the complete absence of the modernization potential of the Norwegian-Finnish concept, which is also associated with the impossibility of placing additional sensors in the already “hammered” electronics of the shell.


Demonstrator of an artillery shell with a ramjet "155 mm Solid Fuel RamJet"


It is for this reason that the Pentagon today focuses on bringing to mind the less expensive concept of adapting high-speed HVP (“Hyper Velocity Projectile”) projectiles, originally designed for use with an EMRG rail gun, to shoot shipboard 127- and 155-mm Mark 45 Mod 2 / 54 and AGS artillery mounts (destroyers of the Arleigh Burke and Zamvolt classes), as well as 155-mm SAU M109A6 and howitzers M777A2. Adaptation of these projectiles to two different calibers “to the disgrace” is simple and does not incur significant financial costs: it is a trivial launch of the mass production of 127-mm and 155-mm pallets, whose smart cores will be HVP projectiles.

The main “chip” of the brainchild of “BAE Systems” is a huge range of flight, which will reach 130 km when shooting 155-mm AGS guns of Zamvolt class destroyers, and up to 80 km - from the ACN M109A6. And all this will be achieved without the use of ramjet engines or bottom gas generator. The whole secret is that the HVP has an aerodynamic “carrying cone” scheme, the main advantage of which is the creation of adequate lifting force with low aerodynamic drag (a similar scheme is used in the ultra-long-range anti-aircraft missile 9М82МВ ЗРС 300ВХNUMX). Consequently, HVP projectiles will be able to maintain flight speed at 4 — 2800 km / h for most of the flight path, including its descending branch.


Three variants of pallets for HPV projectile for various types of guns (from bottom to top: for rail electro-magnetic gun, for 155-mm guns, for 127-mm guns of Mark 45 family)


This feature, causing the preservation of high energy properties of HVPs in tens of kilometers from the exit point of the barrel, makes both the commands of the US Navy and the United States Emergency Commission, as well as the experts of BAE Systems, more often think about the feasibility of developing an anti-missile modification of the projectile. the products were confirmed during field tests conducted during the RIMPAC 2018 naval exercises near Kauai (Hawaii), when the Mk 45 artillery destroyer USS Dewey URO launched 20 shots experimental shells of this type. Even today, HPVs are equipped with advanced tail aerodynamic rudders, which at high speed and kinetic energy will allow intercepting enemy's low-maneuverable aerial objects (of course, when introducing a rod warhead and a compact millimeter seeker with a miniature proximity fuse).

At the second stage of the design of an anti-aircraft HVP variant, transverse control gas engines such as PIF-PAF can be added, which will be supported by maintaining a sufficient internal volume of the “carrying cone” due to the absence of any propulsion system. And most importantly, the launch of large-scale production of these shells can bring down the price from the 85 projected to 55 — 60 thousand dollars per unit (for the standard artillery version) and to 80 — 100 thousand dollars (for the zenith version). And this is a far more advantageous option for the Pentagon than the purchase of three times more expensive "Nammo" air-missiles with worse maneuverability and completely absent modernization reserve.

    History is cyclical. Again we returned to the ideas of the mid 40s of the last century. And apparently the result will be the same. Unguided shells are not accurate enough for ultra-long firing, and guided ones are close to missiles in price. In short, they will play and postpone until better times.

      Or maybe they are trying to get involved in an expensive unpromising race, or they hide the true goal, or hope to get some other useful result.

    At such ranges, it is easier and cheaper to use a rocket:
    1. Less load at launch on REA.
    2. There are no problems with the placement (arrangement) of REA and the engine in the shell
    3. No need for guns, but PU - simple.
    The American idea is noteworthy.

      Forgive me, but as close to IT, I am embarrassed that the mattresses are ready to "throw out the rocket steering system" and trust "the absolutely exact initially calculated approach trajectory."
      Let me explain - let's start with the fact that the Radar shows a person and "settlement computers" completely untrue information. Yes, yes, let him "make mistakes" not so much, but if the rocket flying at you is closest to you only on the body itself, then your calculations for its interception will already be wrong. For the air defense system can at least steer in the process of convergence at least somehow, and your "anti-aircraft projectile" flies with an almost unchanged trajectory and you made a mistake (and keep in mind that Ballistics is not a Straight, but a Curved trajectory), then your "cunning projectiles" simply will not intersect with the target. Moreover, you need to understand that in addition to the "uncertainty of position", a missile flying at you can also have "physical hardness", that is, as the vaunted "Petriots" firing at the "scads" of Iraqis showed, often riddling this "sewer pipe" simply could not destroy it and even the partially damaged rocket continued its flight and reached intact negative . That is, the more accurate your missile system and the more its damaging effectiveness, the more chances to survive. It is also difficult for me to understand HOW the Americans will be able to take into account the calculations and the error in determining the target and the delay of the reaction as a radar and gun installations (servos), and even more so if it is a Ship, it’s also its own movement.

          I'll try easier - an anti-aircraft missile in flight is trying to "hit" the target, it's like you are driving a car if you see that you don't fit into the turn, turn the steering wheel. And the released "projectile" as in the article, initially and always must be absolutely precisely "aim". And the higher the speed of the "target", the greater the chances of making a mistake in aiming such a projectile and not shooting down the target.
          It is especially difficult if the "cannon" is moving (the ship is floating), because it is like "throwing a small ball into a small pocket while standing still or walking at a brisk pace. lol

          I read not only THIS carefully, but also other articles, such as "modern means of attack" and there, as it is, such "low-maneuverable objects" lol . And excuse me shoot at penny drones with shells under 100.200 thousand bucks belay I don’t know how much it’s for me. Moreover, as I understand it from the article, it means installation on ships, but here everything is generally bad because against ships, well, it is very bad with "slow" or "low-maneuverable" means of attack, because the supersonic "onyx" can be hardly maneuverable, but even it is a hell of a thing you will get, and just because of the problem to calculate the aiming point, taking into account all the difficulties in my commentary listed above.

    at first glance, it looks like complete nonsense: firstly, cone pallets - why? Secondly, throw a 130-caliber discard projectile on a ground target - what's the point? Bearing cone - flattened or what? So there’s nothing to steer

      In conceptual theory, this could have been a ride during the shelling of an enemy ship, but forgive me the pitiful 120 km are considered to be an unattainable distance for rapprochement with a target and yes, the GOAL should be BIG !! The barge niggers faeces shoot balvankami 80 tysch per unit - even the Americas is not pulled. But on the earth everything is generally bad, not every missile hits here, the tank doesn’t always hit the rushing enemy in 5 km, and here they want to get in 130. negative Again, I understand when "chumodans" of TNT are thrown over 60-100 km, but a metal blank is not serious. No.

      But imagine that a cannon ALMOST with an ordinary projectile at precisely this range will fire. What do you say then?

        17 January 2019 15: 57
        But the "almost" ordinary projectile is not so much cast iron (as in the article), namely explosives, which increase both the zone and the force of damage. And now "cast-iron cones", well, 40-80 of these cones will shoot at the enemy battery and why are they "nipping" there, but there will be no chances to hit at least something, well, absolutely. By the way, it is precisely for counter-battery combat that range is needed, because for ordinary targets the closer you are, the better, because this reduces the time of approach and the target does not have time to escape or get into the "slot". Let's not forget that in addition to the "struggle between arts" there is also a struggle between Arta and Raketa and the competition is in PRICE. If shells for art are too expensive, they are more expensive than missiles for belmes, by the way, they are already trying on to intercept shells, and the art is about to block this "negative side".

          Everything is simple here, except for the rocket itself, you also need a carrier to launch it. This is an attempt to unify media and use what is already in stock.

    Any active-rocket shell has accuracy plus or minus bast shoes due to the dispersion of the characteristics of the solid-fuel engine. In this regard, the ARS makes sense only in the case of the use of the GNS of one type or another plus controlled aerodynamic surfaces.
    The question is - and where are these very GNS and guided surfaces in the described shells? laughing

    The conical body, of course, has a certain aerodynamic force, but very small in size. The conical shape (in combination with the correct weight distribution) is used for another purpose - to stabilize the projectile in flight without the use of protruding planes.

    Normal projectile 155 mm. weighs 40-50 kg. carries about 7 kg of explosives. It flies at a speed of about 900 m / s. at a distance of 30-40 km.
    The proposed NATO miracle flies at a speed of 1000 m / s, but not by 40 km., But by as much as 120-130 km. From which it follows that the lion's share of the weight of this shell is fuel for this very flight. As a result, the shell will not carry 7 kg. explosives, and less than 1 kg.
    And what is it for?

    The projectile must be CHEAP! This is the only value of the "god of war". There are different caliber missiles to hit a point target. And here each projectile is more expensive than an object that it can destroy. Where will this projectile (or "Excalibur") fly if the GPS is turned off? And these "Copperheads" and "Krasnopoli" somehow did not shoot very well. Even a cheaper "centimeter" is not very popular .. GOS is not to show you figurines to sparrows .. They are doing crap there and let, the main thing is that ours would not be led

    It seems to me, although I may be mistaken, time will show that at present all these shells are bullshit. Well, there will be no counter-firing and destroy the line of defense for 120 km. Also there will not be and, if necessary, this battery will simply be destroyed by a rocket or aircraft and its expensive shells will be scattered around and ...

    I somehow did not understand, but due to what these projectiles will "maintain a flight speed of 2800-3200 km / h throughout most of the flight path, including its descending branch."? There are no engines on them, so the maximum speed will be at the exit from the barrel, and then it will only decrease.
    Some kind of nonsense!
