I heard that Southwest Science and Industry has a mature turbofan engine for small missiles, not only the navy, but even the air force is interested: "It can meet the turbofan engine used in the YJ-18, which is close to 2 tons, this thing is a baby, just now we are still preparing to develop a joint terrain tracking subsonic cruise missile for land attack of the three services, and now it seems that this thing can also be used, you can tell me more about the situation." ”

Sure enough, some people couldn't sit still, didn't this expose the three-service general-purpose subsonic cruise missile project, and Yang Hui knew at a glance that this was talking about the No. 10 cruise missile on the previous side, and the three-service general-purpose type refers to the Navy's Donghai 10, the Air Force's Changjian 10, and the Second Artillery's Dongfeng 10, and the same missile is just a difference in the way it is launched.

Of course, the subsonic cruise missiles of the 10 series can indeed use the engines originally equipped for the X-55 Tomahawksky missiles, after all, these two missiles are completely of the same level, and of course there is no problem with the same engine.

You only need to pat your chest and promise: "This is rest assured, this engine of our Southwest Science and Industry is the original engine of the X-55 cruise missile from the Ukrainian Madasich, and the general cruise missile of the three armed forces should be a missile similar to X-55 and Tomahawk, right?" ”

was guessed by Yang Hui at once, and many bigwigs felt bored at the same time, they also set off infinite reverie in their hearts.

This is the engine of the X-55 cruise missile, and after this engine, the general cruise missile of the three armed forces will not have too big a problem in hardware, and only need to do a good job of supporting the navigation system in the future. That qiē problem can be solved.

While rejoicing in his heart, Commander Zhang did not forget his original intention this time: the Eagle Strike 18 anti-ship missile. If there was an engine that could propel the X-55 missile on the YJ-18, the situation would be very different.

Almost slapping the table and shouting, "That's great." At the beginning, we were also preparing to use the upgraded version of the small turbojet engine originally approved for the YJ-83 missile, which is expected to push the YJ-18 to reach a cruising flight speed of Mach 0.7, and the maximum range will be between 260-300 kilometers, but now that we have a more excellent small turbofan engine, the missile's flight speed and range can have a very big leap. ”

Hearing this, Yang Hui was not surprised, just the previous YJ-83 missile has a design weight of 1.4 tons, and the cruising speed of this missile is still as high as Mach 0.9, which shows that the engine thrust used on the YJ-83 missile will definitely not be too small. If this missile is improved, it is not impossible to reach a speed of Mach 0.7 with the YJ-18.

And such a planned YJ-18 should not be much different from the previous YJ-18 missile, the previous YJ-18 is designed in accordance with the club series of missile power scheme, the engine is installed on the rotating pylon, and when the missile is needed, the missile hidden in the missile body is rotated out through the guò rotating pylon, forming a pod form similar to that of a civil airliner, which can give the engine the best air intake effect.

The club missile of the previous plane did the same, because it was necessary to ensure the cleanliness of the missile's appearance to the greatest extent. There is no protrusion such as a fixed air intake, which allows the club missile to be launched through the Guò 533 mm Soviet-based fish launch tube, realizing submarine-launched anti-ship attack operations.

And the disadvantages of this design! It is just that the engine of the club missile cannot use a turbofan engine with a large diameter, after all, the engine is to be stored inside the missile body. And there is also a need for a complex rotating mechanism, so that it is certainly not as compact as a fixed engine.

After the diameter of the engine was limited, the club missile could only use a turbojet engine that was one circle smaller. Although this is different from the starting point of the power arrangement plan of the Eagle Strike 18 program just now, the final engine thrust and fuel consumption are very different.

So. There is no problem with the maximum range of 300 kilometers of the YJ-18 missile, which Commander Zhang just mentioned, and it can achieve the same performance as the club missile.

A design like a club missile. In fact, it can't be said to be good or bad, it mainly depends on the needs of the countries concerned to choose, the Soviet Union or later Russia relied on underwater submarines to eat, and the club of this powerful anti-ship missile must find a way to install submarines, which is the direct embodiment of the specific needs of the national conditions affecting the design scheme.

When the last face of the Republic of China was developing the YJ-18, it was already at the end of the first decade of the 21st century, when the Republic already had a series of huge anti-ship missile families, and the underwater power of the Republic at that time also advanced by leaps and bounds, so the engine layout and model selection of the YJ-18 missile also took the club missile route: rotary small turbojet engine.

But now the situation is different, first of all, we must take into account that in the early 90s, the republic's submarine ocean-going combat capability was almost negligible, all submarines are not only old, but the country's national defense strategy also requires submarine forces to operate only within the first island chain, and it is enough to ensure the safety of coastal defense, which is completely different from the needs of Russia's nuclear submarines for ocean-going operations.

In the first island chain, which is a big place, what subsonic combined anti-ship missiles do the submarines of the republic still need, or it is enough to realize the submarine-launch of the YJ-82 anti-ship missile like the previous one, there is no need to sacrifice too much in order to load the YJ-18 missile on the submarine, the F-35 project of US imperialism is a lesson.

Of course, the current Yang Hui still needs to confirm the Navy's considerations: "That's right, using the turbofan engine as the cruise engine of the YJ-18 can make a big breakthrough in the range of this missile, but our question now is, does the army have a requirement to change this missile to submarine-launched?" ”

Out of caution and prudence, Yang Hui asked the navy if it needed to use this missile as a submarine launcher, but the navy looked at Yang Hui with a strange expression after hearing it.

"What's wrong with you, our submarines will use this kind of thing? It is enough for submarines to have submarine-launched versions of YJ-82 missiles for offshore operations, and it is completely meaningless to equip them with high-cost YJ-18 missiles, and YJ-18 only needs to develop air-launched, ship-based, and road-based models, and the rest is completely unnecessary. ”

Since it is not necessary, the situation is easy to handle, Yang Hui immediately thought of a very promising plan, if this plan can be realized, it will be a huge breakthrough, and it will also be a plan to kill two birds with one stone.

Only then did he tell the thoughts in his heart: "As long as the Navy does not have a submarine-launched demand for the YJ-18, we can do it like this." Aren't we ready to develop a universal terrain-tracking cruise missile for the three services? Now it is completely possible to merge the selective parts of these two projects, anyway, the cruise section of the YJ-18 anti-ship missile and the rear part of the missile body of the three-service universal cruise missile can be completely identical. ”

The plan proposed by Yang Hui is also simple, after all, the diameter of the missile body and engine of the cruise section of the YJ-18 missile can completely adopt the same design as the general cruise missiles of the three services, and their work is also low-altitude subsonic cruise flight.

The only difference is that the general cruise missile needs a full subsonic aircraft, and there is no final supersonic requirement, so it is enough to only fly the whole cruise, and the YJ-1 8 needs the supersonic flight at the end, so we will cut off the general-purpose cruise missile, leaving the design of the back part, and installing a first-stage rocket booster that can fly at supersonic speed in tandem, so where do you need to bother to develop the cruise flight section of the YJ-18.

Then now the good thing is coming, using the rear body of the three-service general-purpose cruise missile as the cruising section, the range of the YJ-18 missile exceeds 400 kilometers It seems that it is not a problem, the most important thing is that such a design will not only not increase the weight of the missile, but can also increase the logistics of the missile, which is definitely a good plan to kill two birds with one stone.

Looking back at the range of the club missile, the new YJ-18 scheme can directly surpass it and become a veritable subsonic combined long-range anti-ship missile. (To be continued.) )
