The door of the courtyard house has been welded dead

What Director Li said, that it can be used again after washing, was just a joke.

After the rocket is launched, the distance of more than 2,000 meters plus the kinetic energy when it hits the ground will cause even a steel pipe to be deformed immediately when it hits the ground.

Wisps of green smoke rose from the ground. It was impossible to find it. As fuel, too much kerosene was added after purification. It was not completely consumed after a distance of more than 2,000 meters. The tail nozzle hanging obliquely on the ground was still emitting golden flames from time to time.

"Don't get close yet, wait until the fuel is released before going over~!"

Who knows if the fuel inside will explode like fireworks if we get close to it at this time? When the small jeep arrived, Li Feng jumped out first. Seeing the flames spurting out from time to time, he immediately became alert.

"Hey, I didn't expect it to actually work. It's flying pretty fast, but it's full of fuel, so the warhead has less gunpowder. The explosion range is probably about the same as the original one~!"

The artillery experts from Factory 447 looked at the wreckage of the rocket hanging obliquely on the ground and gave a relatively fair evaluation. Replacing the liquid fuel and lengthening the projectile body only resulted in an extension of the range at most.

Another problem that has not been mentioned is that the extended range greatly reduces the accuracy.

The range of the original 107 is a few kilometers, which is a bit shorter, but there is no need to consider the accuracy too much. Dozens of rounds of fire cover the area at the same time, and the power of the explosion is enough to cover up the problem of accuracy. The long-range rocket means that the dispersion distance will be greater, and the explosive power cannot meet the requirements, so the practicality will be greatly reduced.

"Don't you think it's not worth it~?"

Li Feng squatted down and looked at the smoking and burning wreckage, as if he could see what these experts were thinking.

"If it's worth it, Factory 803 can make it on its own. The technical difficulty is not that great at the moment~!"

The technical difficulty is not great, it is just a matter of adding water if there is too much flour, and adding flour if there is too much water. The 107 rocket can cope with the current battlefield intensity, match the current situation, and the cost is still very low.

But Li Feng knew that in the future, long-range, high-precision long-range rockets, or rockets similar to missiles, would be the ultimate destination if this path continued.

In low-intensity battlefield conditions, the 107 rocket launcher can demonstrate its outstanding capabilities. Once the depth of the opponent's defense line is widened and out of range, it can only be suppressed by artillery. However, the current range of artillery can only barely reach kilometers, and this is a large-caliber howitzer.

If the enemy command post is discovered beyond this range, either aircraft can be sent to bomb it, but the opponent's air defense capabilities must also be taken into consideration.

Just like in Animal Chess, the cat eats the mouse, the dog catches the cat, one thing after another.

"Although I have never fired a short-range rocket, I can find a problem from the test firing just now. The flame ejected from its tail and the trajectory of the tail flame can easily expose the location of its firing position, right?"

"But the 107 is light. That small artillery vehicle weighs only three or four hundred kilograms. It is relatively convenient to move the position. If it is discovered, the worst that can happen is that we can just move~?"

Taking advantage of the gap, the process of technical discussion seemed a bit like deliberate argument. The reason why the Type 63 rocket launcher can be put into service is because of its lightness and simple operability.

"The maximum range is only about seven or eight kilometers. If we want to be accurate, the rocket artillery must move a few kilometers forward. The technical manual describes the optimal range as 1.1 kilometer. If we deploy at such a short distance, what should we do if we are discovered? Retreat~?"

"This is the price that comes with a short range. It is cheap and useful, but what our factory wants to develop is completely different from his, and we take a different route~!" Picking up a branch, Li Feng drew a simulated battlefield situation on the ground. Once the battle line is widened to 20 kilometers, even if we know that there are opponent's command posts, logistics warehouses, assembly stations, airports, docks and other large targets there, we can only stare blankly at the sand table.

"You've seen a gyroscope before? When you whip it, it can keep its own stable rotation and keep its body straight. If it gets crooked, it can adjust itself. If there is such a device inside a rocket, it can transmit commands via radio and use this spinning gyroscope to control the rocket's posture~!"

"You mean a gyroscope?"

The artillery experts, listening to Li Feng's half-baked description, came over one after another, wanting to show off their expertise in front of the factory director.

"I've seen this thing in technical documents before. It should be the gyroscope that Engineer Zhang mentioned. It can allow weapons with a long range to maintain a good accuracy~!"

"For example, I am at location A and want to shoot at location B. I calculate the distance and adjust the shooting angle of the rocket. After the rocket is fired, I calculate the current position of the rocket based on the radio waves transmitted back by the radio carried by the rocket body. When the position is almost the same, I adjust the attitude of the tail wing through the gyroscope. Finally, boom~!"

The tree branch drew an X on the opponent's command post on the ground. Li Feng poked it hard to express the difference between what he wanted to create and 107.

"That's a missile, right? It has a gyroscope and radio transmission. Not to mention the difficulty of researching it, just look at the cost~!"

Engineer Zhang also squatted down and looked at the rocket wreckage welded to the tail fin. This time it was fixed. He didn't know why Director Li wanted to install this thing. Now it seems that it was all for a purpose.

"Rockets can actually be considered a type of missile. In war, sometimes, it's not just about the cost. It's precisely because of the difficulty, high cost, or other reasons that other factories feel it's too troublesome and don't want to do it. We can just give it a try~!"

"Look, you guys understand artillery shells, but I have scientists who study fuel. We'll take it step by step and first reach the set range. Once the range reaches a certain result, we'll improve the accuracy. Eat one bite at a time. The first bite will tell you the saltiness~!"

The fuel in the rocket wreckage seemed to have burned out as everyone was arguing. It looked black, and one of the welded tail fins had fallen off due to the high temperature.

After the wreckage was pulled out of the mud pit by the jeep like pulling out a carrot, Li Feng applauded Ouyang Yi and gave him a thumbs up.

"Based on the fuel consumed, the extended rocket can probably fly about 17 kilometers~!"

Ouyang Yi scratched his head embarrassedly. Li Feng took the lead in applauding, and the other masters followed suit. Regardless of anything else, at least the range was about twice that of the original version.

"Look, isn't this good? The effect is very significant. The next step is to improve the tail nozzle and combustion chamber to increase thrust. The laboratory will develop a more burn-resistant fuel. Let's not talk about accuracy for now, but increase the range first~!"

"In the first stage, the range is increased to six - never mind, it can't be too high, fifty. If it can reach fifty kilometers, I will ask for credit for you. As for the accuracy problem, we will tackle it after the range is solved. That is the second stage. This goal is not very difficult, but it is not easy either~!"

"You know, we are setting a new standard for rockets, a completely different standard from the past~!"

"If we must say, we can just treat it as a smaller version of a missile. In the third phase, we will focus on solving the problem of vertical launch. I will go and get people if they are needed, but we must get it done~!" (End of this chapter)
