　　CCTV News:As the "crown jewel" of modern industry, aero-engine has always been a "heart disease" of China aviation industry. With the establishment of China’s 12th military enterprise in Beijing, Chinese people have high hopes for this aero-engine enterprise, hoping that it can achieve the same achievements as "two bombs and one satellite".

　　Yesterday, the four-day air force aviation opening activity came to an end, and more than 20 military aircraft in the 34-type domestic weapons and equipment attracted national attention.

△ On September 2, 2016, the 2016 Changchun Aviation Open Day was held in the rain, in which a variety of air force active equipment such as H-6K, JL10, JL9 and Air Police 500 were unveiled.

　　At the same time, it also brings people cold thinking: what is the current localization ratio of the big country air force, which has a huge demand for aero-engine industry, and what level has it reached? How far are we from the aero-engine power?

　　Guogui Wu Decryption: Localization has gone through the process of introduction, imitation, improvement and innovation.

　　Guogui Wu, a 57-year-old special pilot of the Air Force, holds the rank of senior colonel. He used to be the captain of the Air Force Bayi Air Show Team and the deputy division commander of an Air Force Aviation Division, with 30 years of flying experience. As an old pilot with actual combat experience, and now a professor in the post-installation teaching and research department of National Defense University, he has unique insights in studying military high-tech, air force weapons and equipment, and equipment safety management.

　　At present, what kind of level is the localization ratio and performance of aero-engines in China? Guogui Wu said in an interview that China has established an independent aero-engine industrial system in the process of industrialization, and the performance of imitation engines reached a very high level in the 1960s and 1970s.Among the main combat aircraft, domestic engines have accounted for about 90%.

　　The so-called localization here refers to the process of introduction, imitation, improvement and innovation.Due to China’s weak industrial base, in order to meet the strong military demand for aero-engines, the Soviet Union’s aid and imported production methods were adopted. On the basis of the introduction and digestion of Soviet engine production technology, the model was improved, and the scale and serialization of domestic production were gradually realized, which basically met the needs of China’s air, land and sea aviation forces.

　　In the 1960s and 1970s, the overall performance of aero-engines produced in China was not much different from the mainstream level in the world at that time. The fundamental difference was that the domestic engines were mainly imitations and modifications, and there was no engine that was completely independently developed and produced.

　　"Not only do we have no independent intellectual property rights, but we also have no core technology." Guogui Wu said, therefore, in the 1980s and 1990s, when the aviation technology of the United States, Europe and Russia developed rapidly, and the third generation fighters were generally equipped with a new generation of turbofan engines, China was still "playing around" in the improvement of turbojet engines, hesitating on the road of introducing imitation and independent innovation, and the gap between China and the world’s advanced level was not large. Not only does the new generation of fighters lack the drive of advanced engines, but the engines in service also have some quality and safety hazards, which are called "heart disease" by Chinese people.

　　Only a few third-generation aircraft of the main fighter are equipped with imported engines.

　　△FWS10 aero-engine is an advanced aero-turbofan engine designed and manufactured by China. It is installed on the domestic J -11 aircraft and can also be installed on the J -10 aircraft after modification. Now it has been mass-produced. It has become an ideal device for the third generation fighter in China.

　　After 60 years of development, China has fighter planes, bombers, attack planes, transport planes and trainers.Systematize the aircraft production capacity of many types of aircraft. In line with this, a relatively complete engine development and production system has been established, which has the series development and production capacity of turboprop, turbojet, turbofan and turboshaft engines. Domestic engines are mainly assembled on fighter planes, fighter planes, bombers, fighter bombers and other main battle planes, and only a few third-generation fighters are equipped with imported engines.

　　For example, domestic fighters such as J -5, J -6, J -7 and J -8 are adapted to corresponding domestic engines such as turbojet -5, turbojet -6 and turbojet -7. With the improvement of stability, safety and reliability of Taihang engine, it has been widely installed on three generations of fighters, such as J -11, J -15 and J -16.

　　In terms of bombers, H -5 and H -6 realized the localization of engines. The turboprop engines used in Yun -7 and Yun -8 transport planes are all made in China.

　　With the maturity of integral technologies such as Zhi -9, Zhi -8 and Zhi -10, the serial development of turboshaft -8, turboshaft -6 and turboshaft -16 engines has been realized on the basis of introduction, which provides a reliable power source for the rapidly expanding domestic helicopter fleet in China.

　　At present, China’s aviation industry is in a stage from big to strong, from following up to catching up to developing on a par or even surpassing corners. Whether it is a new generation of military aircraft such as fighters, bombers, transport planes and drones, or large passenger planes and all kinds of general-purpose aircraft, there is an urgent need for strong and reliable driving of advanced engines. The sound and rapid development of aero-engines has become the proper meaning of the "Chinese Dream".

　　Guogui Wu said frankly that the country has clearly regarded the engine as a major scientific and technological project in the medium and long-term scientific and technological development plan, and has made up its mind to concentrate manpower, material resources and financial resources to independently research and develop a series of new engines. Domestic aero-engines have entered an unprecedented fast lane of development. In this context, the establishment of China Aviation Engine Group can be said to have a long way to go.

　　Development history of aero-engines in China

　　Stage 1: imitation and improvement

　　In 1950s, China aero-engine industry started from scratch and went through a road full of thorns. In 1956, China’s first turbojet -5 engine was successfully copied in Shenyang, and for a long time thereafter, China aero-engines were mainly copied and improved.

　　Even if it is copied, it is not easy. Even if there is no operation manual, it is difficult to disassemble the aero-engine correctly. For example, there are many small holes on the leaves of several square meters and centimeters, and the location of the small holes is very particular, which is determined according to the recorded trend.

　　Until 2002, when the domestic turbojet -14 "Kunlun" engine was finalized, China completed the whole process of self-development for the first time, and became the fifth aero-engine producer after the United States, Russia, Britain and France.

　　Stage 2: successful localization by purchasing patents.

　　The engine used in the flying leopard fighter is made in China and is called "Qinling", which is alsoIt is the first engine product in China that has been patented and successfully localized.

　　From introduction to localization, it has experienced 30 years of industrial upgrading. In 1972, China contacted Britain to discuss the introduction of the civil turbofan engine from rolls royce. In 1974, during the negotiation, to our surprise, China directly obtained the patent of Spey military engine, which was a top product at that time.

　　However, despite the patent, China’s new industrial materials and other technologies were too backward at that time. It was not until 2013 that this road of localization was completed, and it was equipped on the J-H -7 Flying Leopard fighter, and Flying Leopard became the only main fighter in China that completely got rid of its dependence on imported engines.

　　Stage 3: Own independent intellectual property rights.

　　In December 2005, turbofan -10, also known as "Taihang" engine, was successfully developed and became my engine.China’s first high-performance turbofan engine with independent intellectual property rights.

　　The road to research and development of Taihang engine is also quite difficult. During the test flight, more than 200 technical problems and failures occurred successively. After hard work, the "Taihang" engine was finally equipped on the J -15 fighter and successfully made its first flight in 2012. On a group of J -20 equipment exposed at the beginning of this year, some military fans found that a J -20 was also equipped with an improved Taihang engine. Some military experts said that the "Taihang" engine can be directly equipped on the fourth generation fighter, which laid a good foundation for continuing to develop more advanced, mature and reliable engines in the future.

Recently, two high-profile SUV new cars have been launched on the market: Volkswagen Xinrui and Shanhai L7. They have gained a lot of attention as soon as they debuted. Among them, Tuyue Xinrui attracts attention with its price strategy that is close to the people, but carefully comparing the configuration and price, it has to be said that Shanhai L7 is more cost-effective.

So it seems that Jietu Shanhai L7 is more worth buying.

　　Baked starch sausage

　　It is a "online celebrity snack" that many people love to eat.

　　But recently,

　　The starch sausage was "collapsed"

　　Baked starch sausage at roadside stalls all over the country

　　The price is generally 2-3 yuan/root.

　　In the wholesale market

　　The price of starch sausage is about 0.5-0.6 yuan per root.

　　The cost price of factory production is lower.

　　At this price.

　　Is there meat in the starch sausage?

　　What kind of meat, if any?

　　If there is no meat

　　Where does the meat flavor of starch sausage come from?

　　Five common starch sausage products bought by reporters in the market

　　The meat in the starch sausage is mostly bone mud.

　　Commonly used in pet food production.

　　A comprehensive observation of the five brands of starch sausage with high sales volume on the market at present shows that there is little difference in the ingredient list, and they are basically composed of meat, water, starch, white sugar, monosodium glutamate, spices and other seasonings, as well as additives such as sodium tripolyphosphate, sodium pyrophosphate, sodium hexametaphosphate, sodium carboxymethyl cellulose and temptation red, totaling 15 or 6 components.

　　List of ingredients for starch sausage products

　　According to the General Rules for Labeling in prepackaged foods, all ingredients should be arranged one by one in descending order of adding amount when manufacturing or processing food, but the "starch sausage" ranked first in the ingredient list is meat.

　　The staff of a starch sausage manufacturer in Henan revealed that they all use chicken and chicken bone paste, and duck meat is cheaper, and most of them are starch.

　　At present, most of the people who sell chicken bone paste are merchants who operate pet food, and the merchants said: "Bone paste is not recommended for people to eat, and barbecue is not good."

　　The picture shows the "chicken bone paste" product searched and displayed on the e-commerce website.

　　He Jiguo, an associate professor in the College of Food Science and Nutritional Engineering of China Agricultural University, once said that the use of chicken neck mud and chicken rack mud instead of the original meat is essentially adulterated and shoddy, and the nutrients in it can’t be absorbed by the human body.

　　The staff of the starch sausage manufacturer also revealed that the ex-factory price of starch sausage is 80 yuan/box, and each box contains 120 pieces, totaling 24 kg. If you get more goods, you will get a gift, which is basically 50 cents to 60 cents.

　　Starch sausage has less meat but full of "meaty taste"

　　There is essence blessing.

　　It is difficult for consumers to tell what kind of meat is in the starch sausage when they eat it.

　　On the one hand, because the amount of starch sausage meat is small; On the other hand, an important ingredient in the seasoning of starch sausage is essence. Judging from the samples of the five brands of starch sausage purchased, all the ingredients have flavors. The staff of the above-mentioned Henan starch sausage enterprise also directly said, "Don’t worry about less meat and no meat flavor, there are flavors.

　　Henan Shuangrun Food Co., Ltd. Flavor Barbecue Pork Sausage Enterprise Standard Screenshot

　　There is no special national standard for starch sausage

　　Although it looks like ham sausage, starch sausage is not produced according to the national standard of ham sausage, and there is a certain gap between the physical and chemical indexes of the product and ham sausage, so it can not be regarded as ham sausage product.

　　According to the national standard, the sausage is in accordance with the General Rules for the Quality of Ham Sausage (GB/T 20712-2022). In terms of physical and chemical requirements, the starch contents of ordinary, excellent and super ham sausages are ≤10.0g/100g, ≤8.0g/100g≤6.0g/100g respectively.

　　Taking the enterprise standard "Sausage" (Q/PFY 0006S-2023) of Panshan Fuyu Food Co., Ltd. as an example, the starch contents of three products, namely sausage, skin sausage and vermicelli sausage, are ≤10%≤10% and ≤25% respectively.

　　However, other starch sausage manufacturers did not even limit the starch content of starch sausages.

　　So, is there enough meat and corresponding protein in the starch sausage?

　　As it turns out, there is no clear standard requirement in this respect …

　　The protein content of the sample starch sausage purchased by the reporter is 5.295.5g/1009, which is lower than the most common standard of ham sausage. However, most enterprise standards for starch sausage do not make clear requirements for protein and other indicators.

　　In addition, there is no special national standard for starch sausage, and the reference standard seems to be vague.

　　A person from a standardized technical consulting company said that to formulate enterprise standards, it is necessary to refer to the raw material list and technological process of products and then synthesize multiple national standards or industry standards. If the national standard of cooked meat products is used as the basis for enterprise standards, as long as the meat in their products meets the national standard of cooked meat products. Of course, because there is more starch in starch sausage, you can also choose to use the national standard of starch products as the basis of enterprise standard.

　　According to the relevant regulations, the description of enterprise standards should specify the contents that are stricter than the national or local food safety standards. However, in the enterprise standards of Panjin Yufei Food Co., Ltd., Henan Shuangrun Food Co., Ltd. and Panshan Fuyu Food Co., Ltd., only "the lead limit index is stricter than the national standard" is mentioned.

　　The standard of starch sausage has not become higher for more than ten years.

　　Water and fat in enterprise standards

　　The content is getting higher and higher

　　Although it has existed in the market for more than ten years, the standard of starch sausage has not improved obviously with the development of economy and society, but there are some signs of relaxation.

　　Screenshot of vermicelli sausage (Q/PFY 0004S-2013)

　　Screenshot of vermicelli sausage (Q/PFY 0004S-2013)

　　Comparing the two standards, we can see that there is more water and more fat under the new enterprise standard of starch sausage of Panshan Fuyu Food Co., Ltd.

　　In this regard, an expert who did not want to be named suggested that when consumers choose meat products, it is recommended to check the nutrition label and try to choose products with less fat and lower sodium content.

　　Netizens are hotly discussing:

　　The pure starch in the picture has meat?

　　A few years ago,

　　Ham sausage pursues more meat

　　Adding starch will be rejected.

　　Today, some consumers are

　　Turn your head and pursue starch sausage

　　Some people think they eat starch sausage.

　　It’s not for meat.

　　"Starch sausage, since the name is starch.

　　There is no demanding meat quantity. "

　　"The price of starch sausage is only scary when there is meat."

　　"But I don’t like eating any meat."
