[23] Nuwa jihua

Xiaoqiang was busy in 2010 these days, but he was not idle in 1949.

The 491 project established by the central government in response to the emergence of Xiaoqiang has an alias, Nuwa Jihua. As the name suggests, it is to complete the new China across the times and achieve leapfrog development.

The importance that the leaders attach to Nuwa Jihua is unparalleled, and the Chinese people, who have suffered from imperialism, know best that in order to stop being bullied and stand on their own feet in the forest of the Shijie nation, they must build a strong economy and a strong national defense. It can be said that Nuwa Jihua has become the most important work of the central core leadership collective. In the words of the chairman's speech at the internal meeting of the Secretariat of the Central Committee: "This is our most important task at the moment, and without one, she is the only most important task!" is the only top priority! ”

Around the gray cement building where the 491 Project Headquarters is located in the northwest of Beijing, where the old foreign military camp is located, the security work has reached an unparalleled ultra-high level, even the alert level of Zhongnanhai cannot be compared with it at this time. The barbed wire fence has already enveloped the area, and the military region has even transferred an entire field division to surround the area from the periphery. To enter its central area, there are as many as five fixed checkpoints to check documents. The mobile sentinel is even more heavily loaded with ammunition, checking all suspicious people entering and exiting the periphery.

Recently, the lights have not been turned off every night in the conference room of the Secretariat of the CPC Central Committee, and the lights inside are bright and mixed with the smoke of cigarette smoke. The chairman's original plan to visit the Soviet Union has been revised here, and now the first draft has been set, and it has been decided that Comrade Shaoqi will visit the Soviet Union for negotiations instead, and the original political goal will remain unchanged, and the original loan of 300 million US dollars will be changed into a fund for the training of foreign students. It was proposed that the loan be used to send students and Jishu workers to the Soviet Union for training and to establish the country's education system.

Xiaoqiang brought the coal mining equipment and jishu books in the early stage of the experts day and night after the experts have made a preliminary judgment on this basis, using this mining method and new tools, conservatively estimated that the national output will exceed 100 million tons in 1950 next year, which is similar to Xiaoqiang's original purchase of equipment, the seller claimed about 60 million tons of mining capacity. Coupled with the original mining capacity, it can indeed exceed 100 million tons. That's a threefold increase from more than 32 million tons in 1949!

These analytical data have strengthened the confidence of the Central Committee, and the chairman also put forward a novel slogan of "grasping two grasps and one thing to keep in mind", that is, "grasping science and technology with one hand and production with the other, and keeping in mind the revolutionary ideal and communist mission." This slogan was immediately distributed to the whole country by the Propaganda Department, demanding that it be studied and implemented.

At that time, the cost of an international student was 500 rubles per month, plus 5 years of clothing and stationery for four seasons (the first batch of students studying in the Soviet Union basically did not know Russian, and they first learned the language for one year after going abroad). This is 500 rubles per month, which is equivalent to the annual income of 25 to 30 peasant households! At that time, when Comrade Shaoqi was speaking to the international students who were about to leave, he asked everyone to "get good results, preferably five points, four points are barely enough, if you take the test with three points, you don't need to talk to the leader, and you can go back to China by yourself." "In fact, Chinese students are also known for their hard work. The symbolic* event of the success of these public students in the Soviet Union was that Gao Jingde passed the defense in the Soviet Union in May 1956 and became the first person in New China to obtain a doctorate abroad.

The chairman's decision to spend all the $300 million loan on education has caused an uproar, and people in the education circles have rejoiced, and some of the leaders of the central government who have not been able to contact the leaders of the 491 Project are dumbfounded. How could many industries be built without Soviet assistance? In the face of these doubts, all the leaders participating in the 491 project unanimously stated that the leaders of all levels and local organs should resolutely obey the decisions of the central government and have no worries.

So the country began to select international students, politically qualified, excellent grades, foreign language standards have become the basic three standards, and the scale of this dispatch will be unprecedented, with groundbreaking significance, for 1949, the country only 117,000 college students (of which eighty percent are studying liberal arts) era, it is not easy to send more qualified international students.

Xiaoqiang has just crossed back here on December 15th, and was taken to the hospital for blood transfusion by Xu Qishan and Wei Guo, who greeted him, and the blood testing equipment brought by Xiaoqiang last time has begun to run in the General Military Hospital, and the first batch of type O plasma that has passed the test and matched Xiaoqiang's blood type has been properly stored in the cold storage, waiting for Xiaoqiang to come back from this mission.

After a full two hundred CC of refrigerated plasma was slowly injected into his body, Xiaoqiang began to feel cold on his body, and even his legs and stomachs were a little twitching, so he wrapped the cotton coat handed by Xu Qishan even tighter. This body chills are a common condition after blood transfusion, and it is normal, but the body will be uncomfortable for a while.

"Secretary Cao, Nie Shuai instructed that you go home and rest after the blood transfusion." Wei Guo said.

Xiao Qiang shook his head slightly, and said: "No, I have to go to the warehouse to watch the handover to rest assured, some things are estimated that the comrades who received them may not have seen them, and those bombs and torpedoes or something, if I don't explain it in person and see the handover completed, how can I sleep." ”

looks like he can't help Xiaoqiang, and what he said is indeed reasonable, after all, many materials are indeed unheard of for the poor and white New China in 1949, let alone seen it. The two drove back to the warehouse with Xiaoqiang.

In 2010, when waiting for materials, Xiaoqiang had rented all the warehouses under construction and unbuilt around the warehouse in the northern capital in accordance with Jihua, and the warehouse area was originally a logistics distribution center planned by the local government, with a total planning of 150,000 square meters of large-scale warehousing and logistics distribution center. At that time, Xiaoqiang's big gesture shocked the mayor of Beijing who was in charge of the district, which was a big list and a big achievement!

Before Xiaoqiang came here, the occupancy rate was less than 25%, and this time the project has achieved its goals for the next few years. So the district mayor was excited, and the lead project investor signed a three-year contract with Xiaoqiang, agreeing to pay it every six months and halve the rent. The first year is settled according to the rent of 8 million yuan for half a year. At that time, Xiaoqiangle was broken, otherwise thousands of planes could be piled up there, with the continuous large open-air cement floor and many large warehouses of this storage and distribution center, it can be regarded as a complete solution to the landing point problem of land trade according to Jihua.

When Nie Shuai, Minister Li and others heard that Xiaoqiang had returned from completing the mission, they all rushed to the landing site, and they had all arrived at this time. Looking at the planes densely packed like locusts in these warehouses, they were all stunned, no! It should be said that I was deeply shocked.

Although you old commanders have fought all their lives, who has ever seen such a scene of thousands of planes gathering? This kind of extreme visual shock and impact can only be experienced by seeing it with your own eyes.

Seeing that Xiao Qiang was back, Nie Shuai stepped up with an arrow and slammed Xiao Qiang's shoulder.

"You kid, what a beautiful job you did now! I've never seen so many planes in my life, and now I'm worried about when so many planes will arrive! ”

Minister Li also came up and hammered Xiaoqiang hard.

Excitedly said: "You kid will give me a problem!" So many planes, how do you tell me to keep the job secret! Didn't you say that you would strive to purchase more than 300 planes! It's a thousand, right? ”

The two of them hammered while talking, but at the same time, the two of them were happy to daxiao, and that happy touch made everyone around them excited and inspired!

Oh, yes! Overnight, China had so many planes! It's a dream. No, even if you dream, you would never dare to dream like this.

Although Xiao Qiang was beaten by the two veteran generals, he was also encouraged by the extreme exhilaration, and he stood up with pride to salute them, and began to show off to everyone present, reciting the homework he had done recently.

"Report chief, here are 157 J-5, 112 J-5, 34 J-5 trainers, and a total of 303 J-5 models. The Jian-5 was developed by China by imitating the Soviet MiG-17F fighter. And the MiG-17F was only put into service in 1952, which was improved according to the problems exposed in the air battles on the Korean battlefield, and it can be said that it is an extremely targeted fighter and the nemesis of the f86. ”

Xiao Qiang told these veterans about his limited knowledge:

In fact, the Soviet Union sold the MiG-9 jet fighter to China at the beginning, to say that this MiG-9 aircraft is really bad, it is the first jet imitated by the Soviets after capturing a large number of German jet fighters Me262 and He162. As a result, the Soviet Union adopted the method of self-development and combined with copycats, referring to the design ideas of the Ta-183 that had just been designed and not yet produced in Germany, and came up with the MiG-9.

This MiG-9 is quite a tricky thing, the plane has a tendency to rise in flight, almost unable to suppress it, the Soviet Union's own hero test pilot after getting off the plane said that the vibration is so strong that his eyes are still trembling at night.

The hairy bear is notoriously rough, and after the MiG Design Bureau made a slight improvement to the trembling BUG, the MiG-9 finally began to perform internal test flights, and as a result, in front of the leadership of the military and the Ministry of Aviation Industry, the MiG-9 and its hero pilot crashed headlong into the ground and died honorably.

It is such a pit thing, the Soviet Union produced more than 1,000 planes, and the more it was built, the more faults were found. In particular, the muzzle in front of the air intake, every time the gun is fired, the engine swallows a lot of smoke and causes a stop in the air, and the recoil of the gun also gives the pilot a headache, resulting in a decrease in shooting accuracy and a loss of flight performance that is difficult to overcome.

Finally, the big head appeared, and in the face of the threat of the Korean War, the Chinese wanted to buy fighter jets. As a result, more than three hundred MiG-9s were sold to China. Before he could go to the battlefield, the pilot found that the plane had serious problems, and it was extremely difficult to maneuver, and there were crashes from time to time.

Let's see what Stalin later said: "Since the Soviet Union was unable to provide China with more MiG-15 planes in the past, and estimated that the MiG-9 aircraft could rival the most American jet fighters, now it seems that this was a mistake, and the responsibility for this mistake lies with the Soviet Union." ”

As an action to correct this mistake, the Soviet Union provided China with 372 MiG-15 fighters from six divisions free of charge (only for transportation fees) to modify six MiG-9 fighter divisions, that is, it hoped that China would buy the MiG-9s that the Soviet Union was prepared to provide. Considering that these planes can also be used for training purposes and taking into account the friendly relations between the two sides, the Chinese side will buy them back at the same time.

Even the seller himself feels guilty, you say how bad this thing is the MiG-9.

After China imported a large number of MiG-15s, it was found that the performance of this fighter was indeed more than that of the MiG-9haode, but problems were constantly exposed in the Korean War.

First of all, when the MiG-15 flies at high speed and maneuvers, it is easy to stall the wingtips, causing the aircraft to lose control, tail spin, and crash.

Secondly, the low-altitude flight quality of the MiG-15 is very poor, and it often suddenly enters the tail spin without warning, and once it enters the tail spin, only two or three of the ten pilots can change it, and the other pilots who cannot change it have to abandon the plane and parachute or sacrifice like this.

Also, the stability of the course of the MiG-15 is relatively poor, of course, it is still better than the MiG-9, but there are still problems with the aircraft looking up and running off and excessive vibration.

The MiG-17F, which came out after the Korean War, that is, the prototype of the J-5, learned the actual combat experience and lessons of the MiG-15 in the Korean War, corrected all the above bugs, changed the two pairs of 4-piece wing knives of the MiG-15 to three pairs of 6 pieces, increased the swept wing angle from 35 degrees to 45 degrees, and added a pair of pelvic fins under the belly to increase course stability, and other jishu improvement measures.

Later, the MiG-15 repentant and improved version of the fighter MiG-17 showed its skills in the Vietnam War, completed the territorial air defense task with great excellence, and mastered air supremacy. However, we should know that these jishu improvements are the experience that the Chinese and Soviet pilots who died in the Korean War exchanged for their lives. This is also the reason why after the production of new weapons, the major powers on the Weishenme, Shijie always have to find a way to find a real combat environment to test, and weapons that have not been tested in actual combat cannot be fully believed no matter how good they say.

In short, Cao Xiaoqiang's heart can be punished for the early launch of a patch aircraft for the Korean War, and the little flying eagles of the bald eagle can be eternal......

Let's shamelessly show off some of the improved designs of the J-5 that were quite advanced for 1949, and say more, the J-5 was slightly upgraded in the seventies and eighties, thinking of this, Xiaoqiang couldn't help but admire his shamelessness.

1) The sealed single cockpit can throw off the hatch cover in case of emergency, and the ejectable seat ensures that the pilot can quickly and safely disengage from the aircraft in an emergency.

2) The control system is hard operation. The ailerons and elevators are electrically operated.

3) The hydraulic system is used to retract the landing gear, flaps, speed brakes, adjustable spouts and control ailerons. The air-conditioning system is used for braking, sealing the cockpit, emergency retracting the landing gear and emergency brakes.

4) The aircraft uses a turbojet-5 centrifugal afterburner turbojet engine with a static thrust of 2600 kg, which is much larger than the 2360 kg of the US F-80 Meteor (our army calls it an oil pick), and the afterburner thrust is 3380 kg. At the same time, the F-86 Sabre, the most popular fighter of the US military, only had a thrust of 2,350 kg.

5) The engine is an imitation of the VK-1F engine of the Soviet Klimov Design Bureau, which is the engine of the MiG-17. In June 1956, a team including Wu Daguan, a well-known engine designer in China, successfully imitated the turbojet-5 at Shenyang Aero Engine Factory (now "Shenyang Liming Machinery Company"). In 1964, the production task was transferred to Xi'an Hongqi Machinery Factory, and in 66 years, it was transferred to mass production. The turbojet-5 has an afterburner thrust of 3380 kg, a maximum thrust of 2700 kg, a rated thrust of 2400 kg, a cruising thrust of 2160 kg, and a fuel consumption rate of 2 kg/kg/h to 1.05 kg/kg/h in different states. The fuel inside the aircraft is 1170 kg, and two 400-liter drop fuel tanks are attached.

6) Airborne equipment includes ultra-short-wave command station, radio compass, radio altimeter, beacon receiver, friend or foe identifier, tail guard, rangefinder, etc. These equipment have been improved again and again in the later period, which is equivalent to the level of the 70s, and the progress of electronic equipment is changing with each passing day, and if you have to compare it, you can basically compare all the fighter equipment in the past 50 years to slag.

7) Two Type 23-1 23-mm guns are mounted under the left side of the nose, and one Type 31 37 mm cannon is mounted under the right side of the nose. The reload is 200 rounds. The muzzle velocity of the 23-1 cannon is 680 m/s, the rate of fire is 800 rounds per minute, and the types of ammunition include the Hang-23-1 kill-fire, the Hang-23-1 kill-ignition tracer, the Hang-23-1 piercing and combustion, and the Hang-23-1 training self-bomb. The Muzzle velocity of the Type 37-1 is 690 m / s, the rate of fire is 400 rounds / min, and two bombs of 100-250 kg can be hung under the wings. This powerful firepower ensures that a single hit on an enemy aircraft can tear apart the opponent. ”

After Xiaoqiang finished speaking, although the old marshals did not fully understand, it was obvious that Xiaoqiang's shameless, proud and passionate tone moved everyone, of course, it was okay to say that it was a fool, and everyone in the generals showed a happy red light on their faces, and Nie Shuai was even more eager to board the cabin of Jian-5 and sit for a while.

At this time, an old handsome man with a bold nose and heavy eyebrows spoke:

"Good plane, don't say anything else, just rush this 37 mm caliber cannon, I think it's worth it."

Xiao Qiang hurriedly said: "The reason why the MiG-15 and MiG-17 are recognized as interceptors with super firepower is because of this 37mm cannon, the original design goal of the MiG-15 was to intercept the B-29 'Super Flying Fortress', this caliber of the aircraft gun will tear a bathtub or bathtub-sized hole after the fuselage hits and explodes, and the average fighter will die as long as it hits a shot." ”

Nie Shuai said with a smile: "Xiaoqiang, let me introduce you, this is the chief of staff of our army, Xu Xiangqian, Mr. Xu." ”

This thunderous daimyo almost knocked Xiaoqiang unconscious, and hurriedly stood up and saluted.

Xu Shuai smiled and waved his hand and said, "Don't be restrained, just treat me as Mr. Nie and Minister Li, I am very happy about you, and I will invite you to dinner next time." ”

Xiaoqiang was about to faint happily when he heard this, and he wanted to behave twice.

"This is a J-5A night fighter, an all-weather fighter, equipped with an airborne radar, which can be used even at night."

"Here are 900 J-6s."

Walking to the more powerful Jianliu, Xiaoqiang continued to introduce:

"The J-6 fighter, the prototype of the Soviet MiG-19 fighter, is a second-generation fighter and a first-generation supersonic fighter.

The J-6's airtight cockpit with the hatch canopy gliding backwards opens. There are ejection seats, but the safe ejection speed is limited to 850 km / h. Bulletproof glass for windshield, made of four layers of glass bonded. The back of the seat has a 20 mm thick bulletproof steel plate. Therefore, J-6's emphasis on safety is incomparable to all fighters in the 50s. ”

Mr. Xu nodded and said: "The pilot is too expensive for us, it is to be well protected, I think this Jian-6 design is good, the People's Liberation Army will never allow the life of a soldier to be used as cannon fodder, this kind of safety design should be vigorously promoted." ”

Xiaoqiang nodded in agreement and continued:

"These J-6s with improved electronic systems can detect missiles launched by enemy aircraft at a distance of 100 kilometers without the guidance of ground-based radar.

The J-6 has strong firepower, using three 30-1 30mm cannons, with a muzzle velocity of 780 m/s and a rate of fire of 850 rounds per minute. Ammunition used includes the Aero-30-1 anti-detonation tracer and the Aero-30-1 incendiary incendiary bomb. Four 57mm rocket launchers can be attached, or bombs can be carried. It can carry Thunderbolt-1 or Thunderbolt-2 air-to-air missiles. ”

The CEOs are always fascinated by the weapon system, and when they heard that it was a rocket and a missile, and three 30mm machine guns, their eyes immediately narrowed in unison.

In this way, under the introduction of Xiaoqiang's detailed information, everyone present looked at Xiaoqiang almost with admiration, and regarded Xiaoqiang as a great scientist in the field of aviation.

"This is the H-5 jet bomber............"

Xiaoqiang's teasing continues......
