The workers responsible for pulling the bolt were also under tremendous pressure, and the rocket launcher was equipped with wings, which no one had done before? At least the workers thought it was the brainstorm of their commander, and as the "first to eat the crab", in the event of an accident, the consequences would be ......

The young worker looked left and right, and finally made up his mind.

The rope was pulled ferociously, and the rocket launcher reacted almost simultaneously. The firing pin was unlocked, and the fire cap inside the vent was struck ferociously, and the compacted mixed propellant began to burn.

This is a potion of black powder and ammonium nitrate in the best proportions, and a little clean clay is added to slow down the burning.

The fuel burned ferociously, a large amount of gas was sprayed from the nozzle at the tail end of the projectile body, and the smoke filled the entire launch site.

The rocket, at a speed of nearly 200 meters per second, gives the viewer the impression that it instantly detached from the slideway and flew into the blue sky with a tail of green smoke.

"Ulla!" The onlookers erupted in an alarming roar, and the worker who pulled the bolt covered his ears and soaked in smoke.

There was no danger, and the rockets flew out as they had been supposed to be.

Yang Mingzhi didn't have the heart to cheer with the workers, he reflexively raised the telescope he carried with him, followed the tail of the smoke, and found the rocket that was fading away.

I saw a yellow flame appear in the clear blue sky, and it left towards the north little by little, leaving only a trail of green smoke.

Intuition told Yang Mingzhi that the rocket was not doing vector motion, and it could not get rid of gravity with its predicted flight speed. Its trajectory gradually stabilized, and the swept wings were already working, because the fiery red point of light was so steady and flickering, and its position in the air did not change significantly, but its brightness became less and less.

Fuel is limited, and when the propellant is depleted, and there is no one to power him to fly, the body of the projectile should fall.

The rocket will have a short cruise-like flight state, but it is actually a parabola with a small arc. Depending on the angle of shot, its cruising altitude is different. The height determines the distance it can glide down and glide at, and too high will allow it to perform a dive bomb! If the altitude is too low, the projectile will slowly lose altitude due to gravity, or it will crash early.

The first rocket was successfully launched, it was fired at an elevation angle of fifteen degrees. There are 30 degrees, 45 degrees, and 60 degrees to follow.

The rocket flew continuously, and its speed was actually 100 kilometers per hour faster than the best Soviet fighters. This speed swept wing does its job, but the wingspan is very limited and the lift it provides is also limited.

The fuel is still burning slowly, but it has passed its peak and then started to decline slowly. It hit the ground in a very large arc, and twenty kilograms of traditional black powder carried by the warhead exploded!

After all, this is an experimental bomb, and the fierce Amato's explosives or yellow powder are not used at all. The explosion was not very powerful, but the dust kicked up perfectly marked its point of explosion. The nearest observation team, which was waiting nearby, had already prepared the radio and reported it as soon as it saw smoke and heard noise.

Suddenly, the 10 telegraph operators waiting at the launch point received the same urgent telegram, and one observation group sent only the code of "confirmation" and the number three in the code, and repeated it three times. After receiving it, the recorder pinched the stopwatch for the first time.

Yang Mingzhi watched closely into the distance from the observation deck, and as soon as the rocket launcher was successful, the next step was to investigate on the spot.

Salinchkin placed a large number of observers, who reached different milestones on the road at night, and used this as a starting point to watch the compass move some distance due west to set up an observation post.

The first of these outposts was set up ten kilometers from the blacksmith village, and then every five kilometers, with the farthest two simply being the men of the Homnich station.

What does the so-called number three mean? It was the number three observation post.

The telegraph squad leader solemnly ran to the observation deck and saluted: "Report Comrade Ji!" Comrade Commander! The 3rd Observation Group witnessed the explosion! ”

What does this mean? Yang Mingzhi was a little vague, but Salinchin slapped the table excitedly and stood up. His lips trembled, and he commanded: "You! Go down! ”

"What's going on?!" Yang Mingzhi tugged at the placket of this excited guy's shirt and felt his arm tremble.

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 rocket flew about 20 kilometers! ”

This result was exciting, Yang Mingzhi's expression was still serious, he grabbed Salinchkin's excited body, and shouted: "You calm down! We still have three more bombs to experiment! ”

"That's right! Right! And three more! ”

After some tugging, Salinchkin finally regained his senses. But the result of a cannon twenty kilometers directly encouraged everyone present.

Rigushkov knew that the range of any shell fired at an angle of 15 degrees was not good, and the howitzer must choose 45 degrees to reach its maximum range. He estimated that it would be good for the cannon to fly 10 kilometers, but unfortunately the first observation group did not send a telegram, and the fact was shocking.

Most of the smoke at the launch site was blown away by the breeze, and Yang Mingzhi waved his hand to continue.

With a good start, the haze floating in the hearts of the workers disappeared in an instant, and then look at the three bullets on the square land, they will definitely achieve better results!

Workers hold huge wrenches and unscrew the bolts that lock the tracks, and they use human power to raise the tracks, and when the person in charge of the protractor signals that the bolts are locked when they reach 30 degrees.

The reloading was repeated with ease, and it was the same worker, who gripped the hemp rope again.

Yang Mingzhi had already stood up and raised his right hand. The big hand fell suddenly, and the firing command was delivered.

The excited people did not care about the roar of the rocket launchers, they preferred to let the storm of those tail vents and the huge smoke that followed, and they would not take their eyes off the rocket launchers that were rapidly moving away.

The cannon was discovered three minutes later, and it was very interesting that the fifth and sixth groups of observers sent telegrams almost simultaneously, and their telegrams were numbered by themselves, and this delicate answer was quickly placed in front of Yang Mingzhi and Salinchkin.

What does this mean? The fifth group is about twenty-five kilometers away from the blacksmith village, and the sixth group is thirty kilometers!

Salinchkin was so excited that he almost indulged in his wild laughter. This person did not lose his temper, he held down his trembling legs, and spoke to Yang Mingzhi beside him, and simply stammered a little because of excitement: "Don't ...... Berekov, this is already thirty kilometers! It's unbelievable, you really do what you say! ”

It's just that he noticed that the attitude of the people around him was a little subtle.

Yang Mingzhi was excited in his heart, and he instantly had a bold idea, and after hesitating for more than ten seconds, he replied: "Yes! The technical indicators for thirty kilometers have been reached! However, the experiments don't stop yet! ”

"Do you want to go on? It's already about thirty kilometers! ”

"Of course! We have to keep going! Yang Mingzhi slammed on the table, really scaring the people around him. Then the tall man stood up bravely, pointed at the ecstatic Rygushkov and shouted: "Quick! We're ready for the third one! The angle of shooting is 45 degrees! ”5610
