    In Shenyang, the factory is still the same factory, and the warehouse is still the same warehouse.  A month ago, Zhang Zhenhua, who was rehearsing intensely with prisoners of war, suddenly received a notice asking him to return to the country immediately.  After receiving the order, Zhang Zhenhua immediately took a ride across the river. As soon as he arrived in China, he was sent to the same place where he had been a year ago. He still worked with the old technicians and engineers who had worked with him before.  Compared with last time, there were a few more people added this time.  Upon closer inspection, they were all involved in the development of China's first helicopter, the "Hummingbird".  I don¡¯t know where the superiors transferred them from.  To Zhang Zhenhua¡¯s surprise, in less than a year, Engineer Cao Gang and the others had already completed more than half of the first experimental single-person light helicopter.  Well, although its engine is modified from a truck engine, the rotor on the top is not visible, and even the outer casing is not yet visible, it is just a frame, but even this is a bit fast, right?  Cao Gang saw his doubts and answered with a smile: "Xiao Zhang, this is the result of the hard work day and night by our old guys and the comrades in the factory. It's a little faster, but the quality  I can still trust it." Zhang Zhenhua nodded, "I believe what you said. What's the reason why you brought me here? You guys are more experienced than me." Cao Gang said with a smile.  Xiao Zhang, you are too polite. You are young, smart, and have newer ideas than us. I came to you because I trust you, so don¡¯t refuse." He pulled Zhang Zhenhua to the helicopter and introduced: "Look, now.  The problem is mainly stuck here and here We always feel that something is not right, please help us take a look" "That's it" As soon as work was mentioned, Zhang Zhenhua immediately got into the state and started talking to the masters.  Work together, explore solutions, and experiment iteratively.  Half a month later, the three-piece wooden rotor with steel beams arrived. Cao Gang said that this was the second rotor. The first purely wooden rotor was interrupted during the engine test a few months ago, and the rotor was made of pure metal materials.  The rotor cannot be completed with current domestic metallurgical and forging technology.  After the rotor installation was completed, the intense debugging and modification phase began.  During this period of time, Zhang Zhenhua and these masters have been living and eating in this warehouse.  Along with the rotor came a test pilot transferred from the Air Force.  Everyone is working together in this warehouse to build this experimental helicopter.  Unconsciously, Zhang Zhenhua has been here for a month. The indoor installation and debugging work of the aircraft has been completed. Now it is time to test the true performance of the aircraft.  The first night, someone pulled the aircraft out of the warehouse and to an open space in the suburbs.  Here, heavily armed soldiers are closely guarding the surrounding area.  Prevent unauthorized persons from entering.  Early the next morning, the first test flight began.  Zhang Zhenhua had specifically told Cao Gang before, "Gong Cao, don't fly too high for your first test flight. If something happens, it will be easy to solve. After all, it is not easy for our country to train a pilot." Cao Gang deeply agrees with this.  , "It's a good idea." He immediately reported this idea to the relevant leaders, who fully agreed, and then told the staff below, "Everything is about safety. Don't be too hasty." At nine o'clock the next morning, the test flight officially started.  , after the pilot sat in the cab, he made a ready gesture to the outside.  As the starter blew his whistle, the aircraft's rotors slowly began to rotate.  As the engine roared, the four blades rotated faster and faster.  The strong wind brought by the paddles caused everyone around to move back.  A few minutes later, the plane's landing gear began to slowly leave the ground and rise unsteadily.  Everyone clenched their fists and stared at the bottom of the plane.  One inch, two incheshalf a foot, one foot, watching the plane rise to more than two meters in the air.  Cao Gang said to the commander: "Tell the pilot to maintain this altitude. Do a few more simple actions." The commander immediately followed his instructions and raised the flag. The aircraft immediately stopped in mid-air, and then made forward, backward, and left and right turns.  Wait for action.  There were cheers all around, and Cao Gang waved his fist vigorously, "Very good! Tell the pilot that it's time to come down." The commander gave the command again, and the plane slowly descended.  After the plane stopped, the engine was shut down, and all the technicians gathered around it.  Some asked the pilot how it felt to operate, and some checked the condition of the aircraft's fuselage.  Cao Gang walked to Zhang Zhenhua and said, "Xiao Zhang, are we successful this time?" Zhang Zhenhua smiled, "I can only say that it was a little successful, and I just found a few tricks. After all, this type of aircraft mainly uses piston engines.  It's a little simpler. Of course, if we want to build a small civilian helicopter, this is almost enough, but we have higher goal requirements, so we have to continue.?strength.  " "That's right!  "Hong Xuezhi's voice came from behind. The two people turned around hurriedly and saw that Hong Xuezhi had arrived here at some point. "Hello, Chief!  "Everyone hurriedly saluted and said hello. Hong Xuezhi waved his hand, "Comrades, you are welcome, you continue your work.  "As he said this, he walked to the plane and looked up and down, "It's amazing!  In such a short time, you can develop it and successfully test it in one go.  Amazing!  " Cao Gang hurriedly said: "Chief, this is only the experimental stage, and it is still far from real success.  " Zhang Zhenhua also said: "That's right!  As Chairman Mao said, ¡®This is only the first step in a long march of ten thousand miles¡¯.  " Hong Xuezhi smiled, "I also know that we all have to keep up our efforts!  By the way, I came here just to find you.  "    "Find me?  "Zhang Zhenhua was stunned. Hong Xuezhi said: "Not bad.  Just looking for you.  That novel you wrote has already finished airing on the front line, and I'm on the phone to urge you to get the next one.  "    "ah?  Is it over so soon?  " Hong Xuezhi said: "Is it fast?  It's been more than two months since you came back from the front line, right?  I've also read that book, and it's not that thick.  " "It took me more than three months to write my first book.  "Zhang Zhenhua sighed: "It seems that our frontline announcers should learn more from the storytellers.  That book talks about things that can be clearly explained in a few sentences, and can keep you going for a month without finishing it.  Alas, it¡¯s still a matter of level!  " "You boy!  "Hong Xuezhi scolded angrily: "You've got an advantage and you still act like a good boy!  Engineer Cao, is there nothing wrong with this guy here?  " Cao Gang smiled and said: "No, Comrade Xiao Zhang's work has been successfully completed.  "    "That's good.  I asked him to stay here for a few more days. In addition to helping you, he also needs to write the third book of "Harry Potter".  Did you hear me?  " Zhang Zhenhua asked hurriedly: "Then am I busy with the plane or writing a book?  "Hong Xuezhi smiled and said: "It depends on you.  It needs to be fast, but I will notify other frontline broadcast stations to delay the story as much as possible.  Hurry up, I'll send someone to get it.  "After that, he got in the car and left. Zhang Zhenhua scratched his hair and said, "Why do I have to stay here when I've finished my work?  " Cao Gang patted him on the shoulder, "Xiao Zhang, do you want me to find someone to help you?  " Zhang Zhenhua thought for a while, "It would be best if you could find him.  But," he said, pointing to the helicopter, "Aren't you afraid of leaking secrets?  " Cao Gang smiled and said: "Don't worry, I know it well.  " That afternoon, Cao Gang found a stenographer. So Zhang Zhenhua told stories while working. Because he was telling it in front of everyone, these masters were soon attracted by this magical story.  This gave everyone something to relax in when they were working hard. A few days later, the edited third "Harry Potter" was released to the site sporadically, which caused a break in updates for several days.  The preachers and the coalition forces on the opposite side breathed a sigh of relief, "Finally continued.  "Tokyo, Allied Forces Commander Clark received a letter from 8th Group Commander James Van Fleet. In the letter, he proposed to Clark a plan proposed by the 9th Army to implement an operation called "Showdown" north of Jinhua.  He pointed out: Less than three miles north of the city, both the 9th Army and the enemy's army had fortifications, with only 200 yards between them. There was a road from the northwest about one mile northeast of the 598th Hill.  The Sniper Ridge Mountains extending to the southeast (called 537.7 Heights by the Chinese), the hostile forces there are just blocking our throat, so the casualties will be much greater. ¡°If the enemy can be driven out of these mountains, they will have to.  Drop back to another defensive position 1,250 yards away.  Commander Van Fleet is optimistic about the possibility of a "showdown," considering the maximum firepower currently available from ammunition stocks and the maximum close-combat support from air power. Although Clark has opposed risky operations to capture the high ground in the past, he  He finally said that the "showdown" would create an extraordinary opportunity to capture some positions without making excessive sacrifices. If everything goes according to plan, only 2 of the US 7th Division and the Korean 2nd Division would be able to win.  One battalion could successfully complete this mission. Field commanders estimated that the operation would last six days and cause 200 casualties due to the involvement of 280 artillery pieces from 16 artillery battalions and more than 200 fighter and bomber sorties.  In short, Clark approved the "showdown" plan, but still reminded Van Fleet to only provide routine news coverage of the operation, and to consider the tactical significance of capturing the high ground.  However, the situation did not seem to be as optimistic as the two commanders thought before the war.The staff officer defected to the Volunteer Army with the battle plan, and he was not the only one who leaked the plan.  ***************************************************  ***************** Note: After reading this section, you may feel that it is a bit ridiculous. How can a helicopter be built in less than a year?  how to say?  First of all, this is an experimental product, and it is not an exaggeration to say that it is a large-sized model.  In addition, you can find information about the "Zhi-5" on Du Niang Encyclopedia. In February 1958, Hafei began to imitate the "Mi-4" based on a complete set of drawings and information provided by the Soviet Union. In December of the same year, the first test flight was successful.  Another: China's first helicopter was the "Hummingbird" coaxial reversing single-seat helicopter successfully manufactured in Kunming No. 1 Aircraft Manufacturing Factory in 1945 (some say it was 1939).  The person in charge of this project is Mr. Zhu Jiaren.  Mr. Zhu went to Taiwan in 1948 and soon successfully developed the CJC-3A tandem twin-rotor helicopter.  As a result, development was stopped due to funding issues.
