"'The Firmament 1 ballistic missile, copied from the Iranian Meteor-3 ballistic missile, was first derived from the former Soviet SS-N-5 submarine-launched missile, which is 16 meters long, 0.35 meters in diameter, weighs 16 tons, is fueled by TM-185 (20% gasoline and 80% kerosene), has a maximum thrust of 13 tons, a payload of 1200 kg, can carry a warhead of 760-1200 kg, and has a maximum range of 1500 km. Pen? Interesting? Pavilion wWw. ｂiquge。 The INFO missile adopts customary guidance and has a strike accuracy of 190 meters, which is an effective deterrent force for striking medium and short-range enemy military fortifications. An expert from the Missile Research Center pointed to the missiles that were being finally assembled.

The officers of the navy and air force are better, although they know that this missile is powerful, but it is not prepared for them. The army side and the strategic missile battalion were delighted.

"The technology of the Sky missile is all from Iran, and our research center is currently working hard to master these technologies and will make improvements as needed, this missile is excellent but also has shortcomings." As the head of the scientific research department, Abic has been accompanying Li Mo's identity, and after the expert finished his introduction, he continued to explain by Li Mo's side.

"First of all, the propulsion mode of the Sky missile is backward, and the missile with a single-stage liquid rocket engine has been basically abandoned by various countries in the modern military. Because of the inconvenient storage of liquid fuels, the logistical pressure is high, and accidents are prone to occur. Secondly, the range of this missile is insufficient, and the maximum distance of 1500 kilometers is enough to cover the Gulf of Aden and southern Saudi Arabia if deployed in the north of our country, but the medium-range ballistic missile is a theater ballistic missile, and the best way to strike is to attack with a missile with a range higher than the target, that is, the best strike distance of the Sky 1 missile is 300-500 kilometers. If the enemy target is within this range, the missile can directly rush out of the atmosphere after being launched, and when it reaches the target, the missile is basically already in space hundreds of kilometers higher than the target, and then dives down at an extremely fast speed, and can basically reach more than ten times the speed of sound to dive from a high altitude to hit the target, and it is almost defenseless. The distance of 300-500 strictly limits the combat use of the Sky missile, and it can only be an excellent homeland defense missile and a front-line offensive missile, and it cannot become a relatively excellent deterrent missile at all. ”

Li Mo and several people around him heard the dissatisfaction in Abic's tone, and couldn't help but look at each other. Others may not understand, but Li Mo knows that Abic must have studied the 'Sabre' missile, and he doesn't look very well at the sky of this imitation of the Meteor missile.

Although Li Mo also somewhat agreed with Abic's words in his heart, as the boss, he couldn't directly agree, because Li Mo saw more and farther.

With the help of Iran, the missile technology of the Xingchen Group has only just begun to develop, and it is impossible to develop it overnight, and Li Mo has now paid more and more attention to the basics, such as the aircraft side, Li Mo asked the aviation experts of the power institute to study the propeller aircraft first, first, to run in the scientific research team, and secondly, to train and train those technicians who lack knowledge.

"Abic, how's the solid rocket engine research?" Li Mo diverted the topic and asked.

Several people around him also pricked up their ears, especially the poisonous snake, who is now the commander of the strategic missile battalion, and his understanding of missiles has also been studied every day during this time, and he has added a lot of knowledge, so he naturally knows the use of solid rocket engines on missiles.

Just now he was going to open his mouth to put forward this opinion, but he didn't expect that the boss had already given an order to study solid rocket engines with the scientific research department.

"Boss, the solid rocket engine is composed of four parts: solid propellant, nozzle assembly, shell and ignition device, among which the formula and manufacturing process of solid propellant, the materials and processes used in the design of the nozzle, the shell material and manufacturing process are the most critical, which directly affects the surname of the engine. At present, we have completed the design and manufacture of the ignition device, using a powder box composed of black powder, after igniting the black powder through the heating wire, the charge column is ignited; The material of the shell is composite armor composed of silicon-uranium alloy and high-strength alloy steel, which has been able to withstand high temperatures of 3500 degrees and high pressures of 102*107 Pa. The main challenge we face now is the formulation of the propellant and the design of the nozzle. Formula we can follow the existing information, from polyurethane, polybutadiene and other compounds to find the best formula, this only takes a little more time, to find a primary solid fuel propellant is not difficult, the real tricky is the design of sprinkler irrigation, because the solid rocket engine is working with large acceleration, thrust is not easy to control, it is necessary that the nozzle assembly can control the thrust generated by supersonic gas discharge, which involves thrust vector control. In other words, we must have a thrust vectoring control system for the nozzle assembly to control the flight posture of the missile. ”

Vector technology was first developed in the 70s by the aircraft designer Wolfgang of the German company MBB? Herbs came up with the idea of using the direction of the jet in the tail of the engine to change the aircraft's ability to maneuver. In 1985, the U.S. Defense Pre-Research Agency cooperated with MBB to conduct a feasibility study, and in 90 the first tail jet can change thrust demonstrator X-31 left the factory.

In simulated air combat between the X-31 Demonstrator and the F-18 fighter, the X-31 Demonstrator would have engaged the F-18 12 times 16 times if it had not used thrust vectoring technology, and the X-31 had won 66 times when the X-31 had won 64 times if the X-31 had not used thrust vectoring technology.

This kind of scheme to realize thrust vectoring by installing 3-4 tail plates that can be used for internal and external steering in the tail part of the aircraft, and changing the direction of the tail jet flow by the steering of the tail plate to achieve thrust vectoring is characterized by no need to make any changes to the engine, and is suitable for experiments on active aircraft, and the structure is simple and the cost is low. But the disadvantages are also obvious, that is, the increased tail weight, thrust vectoring work efficiency is low, which is not good for aircraft stealth and supersonic cruise.

Human command is infinite, thrust vector technology is valued by the political axe of various countries, and is used in the research and application of the next generation of military aircraft, such as the current vector technology, from the control mode to distinguish there are several: binary vector technology, applied to the F-22 fighter; Axisymmetric vector technology will be applied to Su-35, Su-37 and other aircraft, flow field thrust vector technology and so on.

Speaking of which, binary vector technology is the earliest and most mature in research; Compared with axisymmetric vector technology, the function is more superior, and the technical requirements are higher. The flow field thrust vector technology is the latest in research, the development of progress and the greatest potential, although there is still a way to go in practice, but it is foreseeable that this vector technology will be the most promising.

At present, the missile solid rocket engine nozzles of various countries are basically the practical X-31 verification machine by installing a few pieces of redirection steering tail plate, because the missile is a consumable, this way is the simplest, the cost is also the lowest, and the missile is not like the pursuit of maneuver like the aircraft, and the thrust vector control is enough for the flight posture of the longitudinal missile. However, with the maturity of binary vector technology and the development of manufacturing processes, the cost is definitely getting lower and lower, and now many missile engines have adopted new vector technology.

Having said so much, the main meaning is one, whether it is thrust vectoring technology or solid rocket engine, or missile technology, it is still an advanced technology mastered by a few countries. Somali Xingchen Company has been able to have its current achievements, mainly because Li Mo himself is also good at 'long-sleeved dancing', and has seized the opportunity several times to seek benefits and benefits for himself.

North Korea and Iran, both have missile technology, but the two countries' medium-range missiles, whether single-stage or multi-stage, are practical liquid propellants, the two countries of solid rocket engine research and began more than 10 years, so far, the two countries have not mastered the mature solid rocket engine technology, in addition to the lack of technology in the material, nozzle vector technology is also an important problem.

At the beginning, after learning that Li Mo had the technology of silicon uranium alloy, a superalloy, in his hands, the political axes of the two countries immediately came to want to cooperate, and the purpose was nothing more than to make up for the problems in this military technology. Although the thrust vectoring technology is very demanding, the two countries have studied it for many years, not to mention the most advanced axisymmetric vector technology and flow field thrust vector technology, the first two simple and mature vector technologies can always master a seven, seven, eighty, eight, eight or eight times, and now with the silicon-uranium alloy provided by Li Mo, the time for the two countries to come up with a mature solid rocket engine is not far away.

Once the solid rocket engine is mastered, the missile technology of the two countries will make a great leap forward, and if the two countries can achieve complete complementarity in missile technology, perhaps in the near future, the two countries will really be able to produce multi-stage composite propelled intercontinental missiles, and once that time comes, war may not be far away.

Listening to Li Mo and Abic talking in a low voice, the poisonous snake felt like his heart was being scratched by countless little hands, and it was itching.

Seeing this kind of missile, the most urgent thing for Viper is to be able to deploy to the strategic missile battalion as soon as possible, and the most important thing is to equip the Sky missile with a nuclear warhead.

What is a Strategic Missile Battalion? To put it simply, it is necessary to equip nuclear weapons with the name of strategic nuclear deterrence. The Firmament 1 missile can be equipped with 760-1200 kg of warheads, and the more than ten nuclear warheads stored by Xingchen Company, the smallest yield is several nuclear warheads with a yield of 500,000 tons, due to the use of uranium-235 as nuclear raw materials, with one kilogram of weapons-grade enriched uranium equal to 2500 tons of yield, this nuclear warhead is nuclear raw materials alone, up to 200 kilograms, in addition to other nuclear devices, the total weight is almost 500 kilograms, it seems feasible to install on the Firmament 1 missile, but don't forget, With a range of only 1,500 km, this missile is a ballistic missile, but it can also be said to be a tactical missile. Tactical missiles with strategic nuclear warheads are clearly inappropriate. The miniaturization of nuclear weapons is also one of the focuses of Laboratory No. 9, but because Li Mo once instructed that most of the manpower and material resources should be put on the research of extraterrestrial materials, the miniaturization of nuclear weapons is still a long way off.

As early as the 90s, the most advanced nuclear bomb in the United States, the W88, had a yield of 475,000 tons, but weighed only 350 kilograms. These warheads are all plutonium-239 nuclear fuel, which is lighter than pure uranium-235 nuclear bombs at the same yield. However, Li Mo only obtained a few nuclear warheads with plutonium-239 as nuclear raw materials from the nuclear weapons base, and the others were uranium-235 nuclear bombs, which often weighed several tons, and it was impossible to install them on the Sky 1 missile.
