Although the core machine was completed, the assembly of the entire aeroengine still took the project team a week.
This speed cannot be considered very fast, after all, the entire prototype test machine was actually completed two years ago.
This time we mainly replaced some parts inside it.
Especially the turbine disk and tail nozzle developed by the Rocket Research Institute.
Although the WS-10 engine is not huge in size, its cold and complex metallic luster can still make people feel its industrial beauty.
Everyone standing in front of it was impressed by its violent aesthetics.
Before the introduction of new materials from the Rocket Research Institute, the project team's design thrust for the WS-10 engine was 120KN.
This thrust is actually far from reaching the limit of the core machine. It is only because of problems with materials and processing techniques that the thrust has to be reduced again and again.
This time, some material problems have been solved, and the thrust can be improved.
In particular, the materials developed by the Rocket Academy have basically improved high-temperature resistance.
Let the temperature of the high-temperature gas in the engine increase by at least 20%, so that the thrust of the engine can reach the level of 130KN.
In addition, after the tail nozzle uses composite materials, the weight is reduced a lot, and the aircraft can carry more fuel, and the combat radius is greatly increased.
Although the WS-10 is not an engine developed specifically for the Su-27, the J-10 is originally a third-generation aircraft in the same line as the Soviet fighter, and the compatibility between the two is still quite high.
It took Zhang Zhengjiang a lot of energy to install the WS-10 on the Su-27 for testing.
After all, the Su-27 at this time is still relatively rare in China.
The first batch of 24 Su-27s cost US$30 million each, although a combination of 35% foreign exchange and 65% goods was used as payment.
But it is still very expensive.
Zhang Zhengjiang finally got into this fight by begging his grandfather to sue his grandmother.
Of course, there is nothing we can do about this. At present, except for the Su-27, there is no other better test platform in China.
Engineers with quick hands and feet were busy at the tail of the aircraft, disassembling the AL-31F from the original aircraft.
"Old Wang, can you finish it today?"
Zhang Zhengjiang stared at the pipeline exposed at the tail of the Su-27, frowned and asked the engineer who was still reading a technical manual full of Russian.
The thick technical manual is densely packed with various technical specifications, and only Wang Xu, who has been dealing with Lao Maozi, can read it.
But now he can't guarantee when he will be able to finish it.
Because the Su-27 has not been introduced into the country for a long time, everyone is not very familiar with this heavy fighter, which is considered a top third-generation aircraft even in the world.
At this time, the F-22 of the Takajiang family has not yet flown, let alone officially entered the army, so the Su-27 is definitely one of the most advanced fighter jets at this point in time.
When Wang Xu was young, he went to Mao Xiong's family to study abroad as an exchange student. He studied aircraft maintenance and worked at the Gongqingcheng Aircraft Manufacturing Factory for a period of time.
Therefore, Wang Xu definitely knows the details of the Soviet fighter jets.
But this is only limited to some second-generation aircraft. For the world's most advanced third-generation aircraft like the Su-27, we just started to contact it a few years ago.
It is not possible to understand the structure of the Su-27 as well as previous fighters.
"There is definitely not enough work to be done today. Today is just enough to remove the original AL-31F from the Su-27."
Wang Xu looked at the engineers at work and answered Zhang Zhengjiang's question.
"It will take us another week to install the new engine."
In fact, Wang Xu thought about it for a week and everyone didn't rest.
If you follow the normal engine replacement and maintenance process, it is normal for the first half of the month.
Especially the WS-10 engine is an engine that no one has had much contact with before.
"It seems that we can't make it in time to give a gift to the National Day."
Zhang Zhengjiang murmured helplessly.
Originally, the project team did not have such an idea, but the efficiency and speed of the Rocket Research Institute gave Zhang Zhengjiang a small hope.
But now it seems that it is basically impossible to complete the engine test flight before the National Day.
But from the perspective of others, the research and development speed of the WS-10 project team during this period is simply astonishingly fast.
Especially Wang Xu, who has been dealing with the WS-10 project team before, is even more aware that the progress of the project during this period has been advancing like a rocket.
Of course, it is not wrong to say that you are on a rocket. After all, the main business of the Rocket Research Institute is to make rockets.
"By the way, how did you do it? The research and development speed was so fast during this period?"
Wang Xu finally couldn't help but ask.
As the country's most advanced combat engine research and development project team, the WS-10 project team is not really part of the team, and they still don't know the specific details inside.
Even Wang Xu, who had been dealing with engines before, was not very clear.
However, there is no need to keep this matter secret, especially since Wang Xu is about to join the WS-10 project team, so there is nothing wrong with revealing some information in advance.
"Thanks to the help of the Rocket Research Institute, they have recently made considerable progress in material manufacturing and processing, and introduced many core materials suitable for engines, which solved our big problem."
Speaking of the reason, Zhang Zhengjiang became energetic.
On the contrary, Wang Xu was a little puzzled after hearing this. His impression of the Rocket Research Institute was still at the beginning of the year.
At that time, the Rocket Research Institute had just failed to launch a rocket and was facing serious problems such as the exodus of personnel and a lack of funds.
"Rocket Research Institute?"
Wang Xu frowned.
"Aren't they almost unable to survive?"
“Where will the money come from for development?”
Faced with Wang Xu's doubts, Zhang Zhengjiang was not surprised. After all, except for the top management, generally only people within the aerospace system knew about the situation here.
It's normal for Wang Xu not to know this.
"The new director of the institute has developed several new materials and used material preparation technology to revitalize a military factory that was about to close down."
Zhang Zhengjiang lit a cigarette and told Wang Xu about the dramatic changes in the Rocket Research Institute in the past six months.
"Hey!"
"That factory was also very lucky. It participated in the Canton Fair and grabbed a lot of orders."
"The Rocket Research Institute has also received a lot of money, but the higher-ups won them a rocket launch mission and started again."
Zhang Zhengjiang took a deep breath of cigarette and said calmly.
After listening, Wang Xu didn't ask any more questions.
It’s enough to know this much. It’s better not to know anything more in-depth.
