Chapter 583 Upgrading Lifespan (Update)

The life of an aircraft depends on two aspects.

On the one hand, it is the service life of the fuselage, and on the other hand, it is the service life of the aircraft engine.

The service life of a military aircraft is a very general term. When designing a military aircraft, economic efficiency is considered as a secondary goal, and performance should be given priority, so the service life of the main components is not uniform. The use environment faced by military aircraft is very complex, and high-intensity use and harsh environment use have a great impact on the service life.

For example, an engine with a design life of 600 hours may have to be scrapped after more than 100 hours on the battlefield, and it may not be able to turn over the first overhaul cycle.

And this also reflects the importance of ground maintenance and maintenance work.

Normally, the service life of a fighter like the Soviet Union is about 20 years and 2,500 hours, and the service life of the engine is 500~1,500 hours.

The service life of the fighter of Europe and the United States will be longer, and the service life of the engine will also be longer.

This does not mean that the military aircraft of Europe and the United States far exceeds the military aircraft of the Soviet Union, but that the combat concepts of both sides are different.

The Soviet Union's combat philosophy is that once a real air battle begins, the survivability of an aircraft rarely exceeds 1,000 flight hours. Therefore, an aircraft engine is very expensive, and it is meaningless to be able to fly for 3,000 hours when a real war comes. If it is shot down in less than 3,000 hours, the expensive engine will be gone.

Therefore, the Soviet military theory is not as good as building some cheaper and larger quantities that can support military operations.

Therefore, the Soviet equipment, whether it is land, sea, or air equipment, is simplified as much as possible, and never made very complicated.

When Europe and the United States bully the weak, they rely on the advanced nature of their aircraft and equipment, just like adults punching the Nanshan Nursing Home and kicking the Beihai Kindergarten.

The Soviet Union is different. When it bullies the weak, it relies on the steel torrent, directly submerging it and taking it away in one wave. If it is a force to be equal, it is a hard fight, relying on the advantage in the number of equipment to kill the enemy.

Just like during World War II, Germany's tanks and aircraft were advanced enough, but they were eventually consumed and dragged down by the Soviet Union, and then in the later period, they had to face the Soviet Union's tank steel torrent and thousands of aircraft.

The Soviet Union's combat concept against the Western camp was similar. Even if two or three aircraft could defeat one NATO aircraft, a few years later, the Soviet Union's steel torrent and tens of thousands of aircraft would be unstoppable.

The Soviet Union's combat theory was based on actual combat and war.

If the S3 season really broke out, to be honest, Liu Tao didn't think that Europe and the United States could resist it, and the Soviet Union would most likely plant the red flag all over the world.

But Liu Tao knew that the S3 season would most likely not start in the future, at least in the next three or four decades, the S3 season should not officially start.

So he paid great attention to quality and service life, which could greatly reduce the cost of equipment use.

To upgrade the service life, naturally there are two aspects, one is the body, and the other is the aerospace engine.

Liu Tao upgraded the body life to 20 years and 8,000 hours, and the engine life to 3,000 hours.

This means that even if the engine life reaches its limit, the aircraft can continue to be used after the engine is replaced.

Later, Liu Tao increased the range and increased the maximum range to 2,000 kilometers.

After upgrading one by one, the J-7 still looks the same, but in fact it has changed.

The performance has been greatly improved.

After leaving the hangar, Liu Tao went to the production workshop again to participate in the manufacture of a J-7 trainer aircraft. He did not forget to accumulate upgrade points by participating in the manufacture of the J-7 trainer aircraft every day.

After all, it will be more difficult to upgrade the aircraft by using it and accumulating experience points.

On this day, Liu Tao returned to the headquarters of Panshan Group.

This year's Spring Festival is very special for Panshan Group because there is no holiday this year.

Liu Tao held a party group meeting to summarize 1987.

There were 13 party group members in the entire Panshan Group Party Group Meeting, and Liu Tao, the party group secretary, presided over the meeting. In addition to these people as decision-makers, there are also heads of various third-level companies attending the meeting according to the meeting agenda.

In 1987, Huaxia South Ordnance Industry Group Corporation was no longer the company with the highest revenue. Huaxia Southwest Industrial Group Corporation and Huaxia Southwest Electronics Group Corporation both had revenues that surpassed that of Huaxia South Ordnance Industry Group Corporation.

Throughout 1987, Huaxia Automobile Group, Huaxia Motorcycle Group, and Southwest Machine Tool Industry Group under Huaxia Southwest Industrial Group Corporation performed the best.

Huaxia Automobile Group is currently the largest automaker in China. Whether it is the production of trucks or cars, it far exceeds the total of other automakers in the mainland.

And this growth rate is still growing at a very impressive rate every year.

In the past year alone, Huaxia Automobile Group sold 100,000 trucks and 500,000 cars in the mainland.

Huaxia Automobile Group also has many subsidiaries.

Similarly, Huaxia Motorcycle Group has also achieved brilliant results in the past year. In this era, there are still many Chinese people who cannot afford cars. You can't afford cars, but you can buy motorcycles!

Not only urban residents buy motorcycles, but people in towns and villages also buy motorcycles!

In the past year alone, Huaxia Motorcycle sold more than 1.8 million motorcycles in the mainland.

The Southwest Machine Tool Industry Group is the largest machine tool company in China, and has sold more than 20 billion yuan worth of machine tools in the past year.

In addition to the Southwest Industrial Group Corporation, the revenue of the Southwest Electronics Group Corporation has also seen explosive growth.

In addition to the explosive growth in computer sales, there are several important reasons. One is the rapid development of the electronics industry. The market growth of semiconductors, display tubes, LCD screens, etc. is very fast, and the sales of refrigerators, air conditioners, and color TVs have increased significantly.

This has allowed the Southwest Electronics Group Corporation to surpass the Southwest Ordnance Industry Group Corporation in terms of revenue.

Of course, if you count profits, that may not be the case.

Because the arms trade of the Southwest Ordnance Industry Group Corporation is extremely profitable and belongs to the highly profitable industry.

The profits of the Southwest Ordnance Industry Group Corporation in China are very thin, but the profits of overseas orders are very rich.

As for the three secondary companies of the China Transportation Investment Holding Group Corporation, the China Electric Power Investment Group Corporation, and the China Construction Group Corporation, they are all large-scale investments, and no profits can be seen in the short term.

With the summary, Liu Tao and others had a clearer understanding of the situation of Panshan Group.

Especially Liu Tao, he could clearly see that the entire Panshan Group was still in the fast lane of rapid growth.

The profits created by these companies were very high, but the profits created by those companies in Hong Kong were also very high, especially he took advantage of the super black Monday last year and made a lot of money, and he made more money there.

The money left in the US stock market has made a lot of money now with the end of the US stock market crash.

As for the Hong Kong stock market, some funds will be withdrawn after the Chinese New Year.
