"... The First Division of the Education Youth City, with the armored troops as the main force, quickly raided Sreonbee, and captured the port city in the northeast of Kanxun Bay in an hour, or in other words, basically did not encounter decent resistance..." The news quickly spread back to China. ┡Acting┢┢.?.

Even in the depths of Daba Mountain, Liu Yijiu and others received the news as soon as possible.

"They did a pretty trick!" Even though Wang Shunyi didn't know how to march and fight, he could still be clear under such circumstances that Yang Wei and others were still very prepared for this battle.

"The battle to kill the gallon lasted for a long time. It took three days, three times the attacking troops of the defenders, and they also engaged in a fierce street battle with the Vietnamese. Now the two sides confronted at the pass of the Cardamom Mountain on Highway 4. At the same time, the troops of the educated Youth City were moving towards Sihanoukville, cutting off the railway line through Phnom Penh to Kampot to Sihanoukville. The two sides confronted along the river, but the Vietnamese Navy 171 fleet had a very large defense line at sea... "

"Didn't the armored forces of both sides engage in war? The monkey's air force did not dispatch?" Liu Yijiu asked with a frown.

Yang Wei and his team's offense are indeed very fast, although the offense has been delayed for too long.

"The two sides did not explode a large-scale armored war, and the Vietnamese could not afford to lose money. Therefore, the troops of the Educational Youth City started raids with armored forces. They formed a special force for anti-armor and air defense to equip our bazooka, Houyi-2 air defense missile, and Black Arrow-2 anti-armor missile. During the entire battle, Vietnamese fighter jets only appeared twice, one was destroyed and the other was injured. As for the armored troops, they lost 7 tanks and 11 armored vehicles, and the rest were all withdrawn to Sihanoukville..." The person who reported the report explained the war between the Educational Youth City and the Vietnamese in great detail.

In the war there, it is basically difficult to have a large-scale high-tech weapon battle just like on the battlefield between Iran and Iran.

At least now, there is not much possibility.

"Similarly, because the 171 fleet, the troops of the educated Youth City can only surround Sihanoukville, and cannot be taken down!"

"Aren't the main armed transport ships of the 171 fleet hq6o4 and hq6o5 killed by us in the Xisha Islands?" Liu Yijiu frowned. The Vietnamese Navy itself did not have several warships. "Did the Soviet Navy help them attack?"

"No.═. Although the 171 fleet lost two main armed transport ships, there were also some frigates with larger main gun caliber, which were sold to the Vietnamese government by the Soviet Union..."

Hearing this, everyone in the base management committee knew that it now seemed that the naval construction in Nipponsan really had to be accelerated.

However, without the 532 ship, it is difficult to quickly form combat power there.

Over time, the Soviet Union will have more warships in Cam Ranh Bay, Vietnam.

"Notify the 7o1 Institute to speed up the improvement. In addition, our Z-91 weapon test must also be faster!" Liu Yijiu finally made such a decision.

The improvement of the 532 ship is followed by a helicopter platform. When there is no helicopter to board the ship, you can place an additional triple-mounted C8o1 anti-ship missile launcher, which can be fired manually or controlled through the control computer on the ship.

Helicopters do not have much effect on attack, and they mainly assume the responsibility of reconnaissance to make up for the shortcomings of radar.

The improvement of the 532 ship is still a test!

Therefore, Liu Yijiu did not invest much energy in the war in Nipponsan.

The Spring Festival in 1982 was spent in the busy life of everyone. Everything in the base was being carried out in an orderly manner. The other industries in the base were starting to make profits, and the profit situation was still very optimistic.

This made the units under the Ninth Court even more prosperous for a year. The year-end bonuses and other units naturally made other systems jealous. More importantly, the units under the Ninth Court have more New Year’s goods this year, including seafood from the South China Sea, apples from the north, oranges from the south, etc., as if they don’t have money...(.

The year-end bonus of the Ninth Hospital did not rise much, or even did not rise, which made other units less opposition.

Just after the Spring Festival, several leaders of the Ninth Hospital Base began to follow five helicopters to Qinghai through railways, climb to the Qinghai-Tibet Plateau, and began performance testing on the Qinghai-Tibet Plateau.

At this time, most areas on the Qinghai-Tibet Plateau were covered with snow, but Liu Yijiu could not continue to wait.

The educated Youth City needs these helicopters.

Only by showing performance can Iran's Ministry of Defense change their minds.

The twin-rotor helicopter, at present, does not conform to the aesthetic views of these guys.

The test of helicopters is not enough to fly in the sky. Of course, sometimes, even flying is extremely difficult...

"Add to increase the altitude by 200 meters and fly to 640 meters!" On the Qinghai-Tibet Plateau, above the vast snow-capped mountains, five huge helicopters formed a formation and flew neatly.

As the pilot flight helicopter of the entire formation, in the helicopter cabin in front, Liu Yijiu held the walkie-talkie and looked at the blue sky outside. Although it was very cold and he felt difficult to speak, he was still sweating profusely.

"Director Liu, the output power of this helicopter has begun to be insufficient at an altitude of 6,000 meters. Now it is only barely flying at 62oo meters. If you climb up..." Liao Zhuojing, as the chief engineer of the helicopter and also serves as the deputy chief designer, was also nervous and sweating.

The flight of the plane is already very unstable.

If you climb upwards, the helicopter's turboshaft motor does not output enough power and cannot climb upwards, which will easily cause greater disasters due to insufficient combustion efficiency of the motor.

"I know, we must test the ultimate power of the motivation! At higher altitudes, the changes caused by changes in the oxygen content of the motivation must be recorded in detail." The reason why Liu Yijiu insisted on letting Zhi-91 go to the plateau test was to prevent the introduction of Black Hawks in China.

Moreover, only helicopters that can go to the plateau can fly well in any complex environment.

The Republic copied a lot of helicopters back then, but not many helicopters could be used on the plateau, except for some civilian black hawks who carried out their missions.

The plateau environment is harsh and the border problems are also very serious. We must quickly release supplies to this side, and even use them to patrol the border, so that helicopters can be more competent.

Now these helicopters are a bit reluctant at an altitude of 6,000 meters, and the cruise level is not satisfactory, mainly because the aircraft's motivation is not good.

Under Liu Yijiu's order, helicopter test pilot Huang Pingyang replied after receiving it, and began to pull the joystick back, hoping to increase the flight altitude by raising the pitch.

However, as the joystick fell backwards, the helicopter that had been flying was shaking, and the two rotors rotating in the opposite direction were turning slowly and slowly, and the helicopter became heavier and heavier. Even the many indicator lights on the console began to flash randomly and alarm.

"Stretch the distance between the two aircraft and control the flight posture. Don't rush to climb quickly, take your time!" Liu Yijiu, who was in the cabin, was almost unsteady by the violent shaking of the helicopter. The flight status reported by the helicopter behind him made his palms nervous and sweaty.

The few people next to him were even nervous and pale.

The test flight of Z-7 was not completed at all, and there was no experience in participating in the plateau test. Liao Zhuojing, Zhan Like and others personally experienced the test of the aircraft in the helicopter cabin for the first time.

Although Zhi-91 has shown relatively good performance in the previous performance tests and various environmental tests, you should know that this is the Qinghai-Tibet Plateau in winter.

I have been preparing for the Chinese New Year before, and the regular performance tests in the previous few days were very good. After all, the place has not reached the highest altitude yet, and the practical ceiling of the Z-91 is designed at 58oo meters.

After several days of testing, the practical ceiling has exceeded 6ooo meters. Although the flight posture is not very stable, it can be maintained for a period of time.

Now that we haven't climbed many meters up, the flight posture of the plane becomes very difficult.

The bumps are so great that it is even difficult to control.

Liu Yijiu asked to continue climbing up, but once something happened, the plane would fall.

"Director Liu, please put on the parachute!" As soon as Liu Yijiu finished speaking, a middle-aged soldier wearing a thick leather air force jacket came to Liu Yijiu with two pairs of parachutes in his hand and said very respectfully to Liu Yijiu.

"There are all parachutes?" Liu Yijiu frowned.

Helicopter pilots do not have parachutes.

"No, we were not prepared enough at the beginning, there were only three parachutes on it, so..." the soldier said distressedly to Liu Yijiu.

There are several people inside the cabin, and Liu Yijiu and his wife must have. Who said he is the chief designer of Zhi-91?

Deputy Chief Designer Liao Zhuojing and Deputy Chief Engineer Zhan Like are also a must!

"Xiao Liu, put it on. If something happens to you, the project of Zhijiuyi will be over. At the same time, many projects in the base cannot be developed..." Liao Zhuojing did not spend much time in the Ninth Courtyard, but he knew the importance of Liu Yijiu.

Once the helicopter loses control, it will definitely be impossible to survive if it falls at this altitude of more than 6,000 meters!

"This helicopter was designed by us. Mr. Liao, you have participated in more work than me. If we don't have confidence in our helicopters, can our customers still have confidence? Can our troops still feel at ease when using it? Extreme tests must be there! If you are afraid of death, you should put on a parachute. If I don't wear it, I have confidence in them!" Liu Yijiu pointed to Huang Pingyang and his apprentice in the cockpit in front. (To be continued.)
Chapter completed!
