The workers responsible for pulling the bolts were also under great pressure. This rocket launcher was equipped with wings. Who had done this before? At least the workers thought it was the work of their commander's imagination. As the "first to eat crabs"
, once an accident occurs, the consequences are...
The young worker looked around and finally made up his mind.
The rope was pulled fiercely, and the rocket launcher responded almost at the same time. The firing pin was unlocked, fiercely struck the flash cap inside the nozzle, and the compacted mixed propellant began to burn.
This is a mixture of black gunpowder and ammonium nitrate in an optimal ratio. In order to slow down the burning speed, some clean clay is also added.
The fuel burned fiercely, a large amount of gas was sprayed out from the nozzle at the rear end of the projectile, and smoke filled the entire launch site.
The rocket was approaching a speed of over 200 meters per second, giving viewers the impression that it instantly left the slide and flew into the blue sky dragging a tail of green smoke.
"Hurrah!" The workers onlookers roared in astonishment, while the worker who pulled the bolt was still covering his ears, immersed in the smoke.
No danger occurred, and the rocket flew out just as expected.
Yang Mingzhi had no intention of cheering with the workers. He raised his telescope as a reflex and followed the tail of the smoke to find the rocket that was moving away.
I saw a ball of yellow fire appearing in the blue sky, and it left little by little towards the north, leaving only a trail of blue smoke.
Intuition told Yang Mingzhi that the rocket was not making vector motion and could not escape gravity at its predicted flight speed. Its trajectory gradually stabilized, and the swept-back wings had taken effect, because the fiery red light spot was
It flashes so steadily, its position in the sky does not change significantly, but its brightness is getting lower and lower.
Fuel is limited. When the propellant is exhausted and no one provides flight power, the projectile will fall.
This rocket will have a brief flight state similar to cruising, which is actually a parabola with a smaller arc. Depending on the shooting angle, its cruising altitude will be different. The altitude determines the distance it will fall and glide. Too high an altitude will cause
It can perform a dive bombing! If the altitude is too low, the missile will slowly decrease in altitude due to gravity, or it will crash early.
The first rocket was launched successfully. It was launched at an elevation angle of 15 degrees. The next ones were 30 degrees, 45 degrees and 60 degrees.
This rocket continued to fly, and its speed was actually over a hundred kilometers per hour faster than the best Soviet fighter jets. At this speed, the swept wings worked, but the wingspan was very limited and the lift provided was also limited.
The fuel was still burning slowly, but it had passed its highest point and then began to slowly decline. It hit the ground at a very large arc, and the twenty kilograms of traditional black powder carried by the warhead exploded!
This is an experimental bomb after all, and no violent Amato explosives or yellow gunpowder are used at all. The power of the explosion is not great, but the dust raised perfectly marks its explosion point. The nearest observation team waiting nearby has already set the radio
Be prepared to report immediately when you see smoke or hear noises.
Immediately, the ten telegraph operators waiting at the transmitting point received the same urgent telegram. An observation team only sent the code "confirmation" and the number three, and repeated it three times. After receiving it, the recorder
I clicked the stopwatch for a moment.
Yang Mingzhi watched the distance closely from the observation deck. The rocket launcher was successful, and the next step was to investigate on the spot.
Sarinchkin deployed a large number of observers, who arrived at different milestones on the road at night, and used them as starting points, watching the compass move a certain distance due west, and setting up observation posts.
The first such post was set up ten kilometers away from the blacksmith village, and then one every five kilometers. The two furthest ones were simply people from the platoon of the Homnich Military Station.
What does the number three mean? That is the observation post numbered three.
The telegraph squad leader ran to the observation deck seriously and saluted: "Report to Comrade Ji! Comrade Commander! The third observation group witnessed the explosion!"
What does this mean? Yang Mingzhi was a little vague, but Salinchkin slammed the table excitedly and stood up. His lips trembled and he ordered: "You! Get off!"
"What's going on?!" Yang Mingzhi pulled on the excited guy's shirt and felt his arms shaking.
Before Yang Mingzhi could react, he pulled it up like wool and said excitedly: "Do you know what the third observation group means? This first rocket flew about twenty kilometers!"
This result was exciting. Yang Mingzhi's expression was still serious. He grabbed Salinchkin's excited body and shouted: "Calm down! We still have three bombs to test!"
"Yes! Yes! There are three more!"
After some pulling, Salinchkin finally regained his consciousness. But the result of a shot of twenty kilometers directly inspired everyone present.
Liguschkov knew that firing any artillery shell at a 15-degree shooting angle would not have a good range. To achieve the maximum range of a howitzer, it must choose 45 degrees. He estimated that this cannon would be good if it flew ten kilometers, but it was a pity that the first observation
There was no telegram from the group, which was shocking.
Most of the smoke at the launch site was blown away by the breeze, and Yang Mingzhi waved to continue.
With a good start, the gloom floating in the hearts of the workers disappeared instantly. Look at the three bombs in the square land, they will definitely achieve better results!
The workers held huge wrenches and unscrewed the bolts that locked the track. They used manpower to raise the track. The person holding the protractor indicated that the bolts were locked when 30 degrees was reached.
The loading work was repeated easily, and it was the same worker who once again tightened his grip on the hemp rope.
Yang Mingzhi had already stood up and raised his right hand. The big hand suddenly fell down to transmit the order.
The excited people did not care about the roar of the rocket launchers. They would rather let the violent wind from the tail nozzles and the huge smoke and dust that came with it, and watch the rockets that quickly went away.
The cannon was discovered three minutes later. It was very interesting that the fifth and sixth groups of observers sent telegrams almost at the same time. Their telegrams were marked with their own numbers. This subtle answer was quickly placed in the minds of Yang Mingzhi and Sa
In front of Lynch King.
What does this mean? The fifth group is about 25 kilometers away from the blacksmith village, and the sixth group is 30 kilometers away!
Salinchkin was so excited that he managed to hold back his wild laughter. This man did not lose his composure. He held down his trembling legs and spoke to Yang Mingzhi beside him. He even stuttered because of his excitement: "Don't...
Belekov, this is already thirty kilometers! It’s unbelievable, you really mean what you say!”
But he noticed that the attitudes of the people around him were a little subtle.
Yang Mingzhi was excited and had a bold idea in an instant. After hesitating for more than ten seconds, he replied: "Yes! The technical indicator of thirty kilometers has been reached! But the experiment has not stopped yet!"
"Should we continue? It's already about thirty kilometers away!"
"Of course! We must continue!" Yang Mingzhi banged on the table suddenly, which really scared the people around him. Then, the tall man stood up bravely, pointed at the ecstatic Liguschkov and shouted: "
Quick! We are preparing the third one! The shooting angle is 45 degrees!"
