  1. <p> even if the missile able to speed of Mach 3 targets from high altitude, but the face of the other advanced shipboard air defense system, the probability of success is actually not ideal. So for such a goal against the carrier battle group, it relies on a missile can not get good results, you may need a variety of missiles, a small group of multi-channel approach,outlet hogan, useful in different altitude, speed, using different guidance system targets have made better results.</p>

    <p> is not conducive to control structural strength. How to look carefully, you will find YJ-12 and KH-31 still have some differences, YJ-12 uses a beveled inlet,hogan bambini, the equivalent of a slant forwardly extending inlet air across the ramp began to slow pressurization, thereby improving the intake efficiency,hogan sito ufficiale, the structure is relatively simple,hogan prezzi, but the drawback is to shorten the length of the inlet, less efficient, and KH-31 plus use circular inlet shock cone, use shock to improve the efficiency of the inlet cone,hogan scontate, since it is possible to ensure that the length of the inlet.</p>

    <p> 3M80E ballistic missiles at low altitude mode may be less than the range Harpoon anti-ship missiles, but the weight is probably the latter several times. So from the outside perspective, we may not hold too many expectations on a range of conditions at low altitude trajectory YJ-12's, but for supersonic anti-ship missiles, the increase range of relatively simple and economical way is to use high trajectory, we know that high-altitude thin air, low resistance, so the use of high-altitude supersonic ballistic missile mode, increasing its range will be doubled.</p>

    <p> From H-6 mount YJ-12 goes map view, I feel surprised YJ-12 is probably the diameter is smaller than previously,hogan napoli, this can compare YJ-6 H-6 to mount the image, it will found that the diameter of the latter than the YJ-12 much smaller diameter YJ-6 is 0.76 meters, while Russia's 3M80E / SS-N-22 missiles with a diameter of almost YJ-6,scarpe hogan originali, which means that the weight of YJ-12 may much smaller than 3M80E. From the picture you can see the YJ-12 uses a four-axis symmetrical layout Inlet, Inlet was X-shaped arrangement around the elastomer advantage of this arrangement is preferred under normal flight conditions of inlet performance while the structure is relatively simple,nuova collezione scarpe hogan uomo, the future is conducive to the overall layout of the inlet missile flight control system for the less demanding, so we see several supersonic anti-ship missiles such as the Russian KH-31,3M80E have adopted this layout, but it The disadvantage is that the performance of the inlet angle of attack increases rapidly decline, low mobility,parajumper jas dames, there will always be one or two additional inlet located at a lower total pressure recovery back above the bomb, so it will drag the entire performance intake,stock scarpe hogan, reducing engine thrust, additional elastomer opening more.</p>

    <p> in cloth out cover into the equation voyage equal to the number of lift-drag ratio * to the weight of the quotient of the velocity / engine efficiency * launch weight / fuel is exhausted, we know,pjs jassen, supersonic anti-ship missile, although in order to reduce the resistance, so the wing is generally small, so lift relatively minor,hogan prezzi, so the lift to drag ratio is generally not high, only the equivalent of subsonic missiles, 1 / 4-1 / 5, another missile is faster, and therefore need the full power of the engine to work, so it's engine fuel consumption have higher than subsonic missiles, so under the same conditions, the supersonic missile's range is much smaller than subsonic missiles. In the simplest case.</p>

    <p> so its high efficiency, but the structure is more complex. Speed YJ-12 is a matter of concern, the supersonic missile advantage is speed, the other defense systems in the short exposure time, the other side of the reaction time can be shortened from the truth in terms of speed is clearly faster the more good, but at the moment the supersonic missile subsonic ramjet fuel, also known as sub-combustion ramjet engine, its greatest feature is the need to slow down the air flow into the inlet chamber to fuel combustion,hogan outlet online, combustion and therefore relatively stable, but in this process due to the pneumatic it does move, so airflow temperature will rise sharply, eventually causing the engine does not work, so the theoretical limit sub-combustion ramjet engine operating speed is about Mach 6, but considering the restrictions on the project, such as materials,hogan estive, technology and so, in fact, this index also dropped to about Mach 4. There is speculation YJ-12's flight speed is probably the reason. But I have reservations about this indicator, it is because the higher the speed of the missile flight, the structure,hogan interactive, material requirements missiles higher,hogan offerte, because the surface and the air friction and heat elastomer will bomb the surface of a sharp rise in temperature, Thus the requirements for the missile is also very high, so taking into account the cost factor, cost and other aspects,hogan uomo, I believe that speed YJ-12 at about Mach 3 may be more reasonable. YJ-12 index range is another interesting fact supersonic anti-ship missiles than subsonic missile at a disadvantage, this voyage cloth cover from the column formula can get the reason.</p>

    <p> like 3M80E upgrade to 3M80VE, the missile itself did not change, just modify the flight control, cruise altitude will increase to m altitude, immediately increase its range to 200 kilometers or more, can be described as the effect is obvious. But the disadvantage is likely to expose high-altitude ballistic targets, especially in the case of such an advanced ship-borne Aegis air defense system diffusion, use the plus missile vertical launching system,sito hogan world, the reaction shipboard air defense missile capability significantly improved.</p>
