Scrum Jet Extra -Sound Sound Passion Missile Estimation of the shape and performance

　The Scrum Jet Extreme Super Sound Sound Passing Missile "Tilcon" is still a mysterious weapon, which is under development of Russian army and is nearly deploying it.The actual, models, illustrations, etc. were not officially announced, and in the launch experiment held on October 6, it was possible to confirm the state with the cap on the warhead immediately after firing, but it rose with a solid rocket booster.As soon as you dump the cap, you will enter the clouds immediately, and you can not see how the scrum jet will be operated.The video released on November 26 was even more difficult to see by night launch.

　The image at the time of launch is blurred, so it cannot be determined, but it seems that the cap of Zilcon is about twice as long as the ionics.However, there is a possibility that it looks like that in the paint.

　But there is only one thing that can be said.All the forecasts of Zilcon, which had been unofficially announced in unofficially announced in many media, had long tip of the head, and the air intake was located near the center of the second -stage Scrum Jet Flying Body, but 10.On the 6th of the month, the cap of the published video of the test is not enough to cover the air intake.In other words, all the conventional predictions were wrong.It is considered that the Tilcon air intake is attached slightly backwards slightly behind the form with an air intake at the end of the neck, such as the tip of the mechanism.

　This figure is an altitude and distance flight profile in the Scrum Jet Extreme Super Sound Sound Passing Missile, Mach 8 and Mach 6, which was published in the United States's "Review and Review of the Air Force Super Sound Sound Technical Program (1998)".Although it is a design value instead of the actual machine, it cruises over 100 to 110,000 feet (about 30 to 33 km), which has a low air density, and the flight distance is about 50 % different between Mach 8 and Mach 6.Of course, flying faster will reduce fuel economy and the flight distance will be shorter.At the final stage, the speed of the air suddenly drops in low altitude with a strong air density.As there is an air intake that is a resistance source, the impact of air resistance is larger than ballistic missiles.

　If this flight profile is applied in proportion to the Zilcon, if you drop 450 km to Mach 8 to Mach 6, you will be able to fly about 680 km.If you slow down the speed with a scrum jet, it will be meaningless (if it can be exhibited with a normal ramjet if it is Mach 5 or less), this can be estimated to be the maximum range of Zilcon.However, it is not possible to determine that the conditions that flew 450 km in Mach 8 were not flying in the first place, or that they were flying while meandering.On the other hand, there are reports that the maximum range of Zilcon is 1000 km, but it is doubtful whether they can really fly.

Scrum Jet Extreme Super Sound Celebration Missile Interception

　In addition, in the case of an altitude of 20 km, even in normal ground -to -air missiles, the aerodynamic steering has enough air to intercept, so the Scrum Jet cruising missile flies around 30 km altitude to avoid intercept.In order to intercept at this altitude, a side thruster or an intercepted missile equipped with a TVC (thrust biased) is required so that the density of the air is low and fine maneuver is possible.However, even if you can solve high -altitude maneuvering, it will be difficult to intercept if the speed is slower than the target scrum jet cruising missile.It is easy to wait for a ballistic missile that flies on a simple orbital, and the range in time is wide even if the intercept missile is slow, but if the scrum jet cruising missile that moves quickly is a partner, it is a slow interceptor missile.Is extremely narrow.

　Nevertheless, the scrum jet cruising missile is no longer possible to avoid avoidance at the final stage, so if a interceptor missile is located near the landing point, shooting down is easier than ballistic missiles.Scrum jet cruising missiles are slower than most ballistic missiles.In other words, the difficulty of intercepting a scrum jet cruise is due to the difficulty of wide -area air defense.

In case of anti -ship attack

　Assuming an anti-ship attack with a scrum jet cruising missile like Tilcon, the target aircraft carrier has an escort Aegis ship nearby, so you can defend with an existing SM-6 interception missile.In fact, the U.S. Navy is planning a test in SM-6 for a Scrum Jet cruising miscellaneous interception, and it is expected that existing weapons will be able to respond to some extent.The final entry speed of Tilcon is not much different from the "KH-22" wing missile (an air-to-ship missile that glides in a structure like a ballistic missile with a wing), which has been in the Cold War, so it will be possible to intercept.。However, while Zilcon is flying at an altitude of 30 km or more, SM-6 cannot be reached.Therefore, the U.S. military is launching a development plan for the extreme sound speed weapon intercept.

　These interception missile development plans aim to intercept not only Scrum Jet Extreme Super Sound Passing Missile but also extremely ultrasonic glide missiles.
