Since Li Xianghong proposed, he must have discovered some problems, and this problem is definitely unacceptable to others.

Such a problem has never been encountered by the Chinese technical team.

Li Xianghong was not embarrassed at all, and did not think that allowing Soviet experts to participate in fault analysis would cause the Super-7a technology to leak secrets.

Ignoring others, looking at Xie Kai, and said, "I always feel that this happened on the engine, but there is no evidence. The various parameters of the fighter are normal. Through the recording of the conversation between the pilot and the tower, I found that the fighter could not ignite successfully at the last moment, and this situation had never been encountered during the flying dragon's head-raising maneuver."

Immediately, Li Xianghong explained his reasons for doubt.

The Dragon Head is the signature maneuvering action of the Super-7a fighter.

Various large-scale maneuvering actions have been performed countless times before, and the overload is constantly increasing during flight to analyze the structural strength of the Super-7a and whether the design is reasonable.

The engine stops during large maneuvering actions, which is normal. The air ignition can be successfully re-ignited soon.

Engine parking is a controllable operation project in the test flight plan.

To date, the Soviet Union has delivered nearly 300 engines, including a new batch of engines provided. These engines are equipped on the newly produced Super-7a to replace the first batch of Super-7a engines that have reached their flight life, and are also ready to be delivered to Iraq.

The Super-7a that happened to be assembled with a new batch of engines provided by the Soviet Union.

Once there is a problem with the engine, it will eventually affect the entire transaction.

The reason for the failure of Yang Chao driving the Chao-7a cannot be found. The only suspicious thing is the newly provided engine provided by the Soviet Union on the fighter.

I have never encountered any problems before, and after changing the engine, I have problems. I can only suspect that the problem comes from the engine.

"There were no problems with the engines provided by the Soviet Union before, and there was no possibility of accidents in this batch of engines..." said Cui Yuanjia, the general secretary, "We have conducted a comprehensive inspection."

"The Soviets don't have any problems in front of them, but it doesn't mean there is no problem in the future." Xie Kai frowned and looked at Cui Yuanjia, "Those who work on technology should never be superstitious about whose technology is always reliable."

A few words left Cui Yuanjia speechless.

Then, Xie Kai asked Huo Haiyuan and others: "Is the fighter a new engine assembled? Have the physical and chemical analysis of the various components of the engine on the crashed fighter done?"

He Haiyuan nodded quickly.

"It is indeed a new engine delivered. The Soviet Union delivered 60 units, not only used on the fighter jets delivered to the Iraqis, but also used the engines used in the Super-7b for subsequent test flight missions, but also used this batch of engines. The Soviets made some minor improvements to improve maintenance performance..."

He Haiyuan introduced the details.

This made Xie Kai even more confused.

"Although the Soviets were not good in some technical fields, they were still relatively strict in quality control. These engines used the same engine as the MiG-29. It was impossible for them to complete the transaction without regard to production quality to provide us with engines with quality problems in order to speed up the transaction..."

If there is really a problem with the quality, it will affect the transaction of thousands of engines.

The Soviets who were in financial difficulties would never do such a thing at this time.

"Are all the inspection data after the engine comes back?" Xie Kai asked He Haiyuan and others.

He can only rely on his experience to see if there are any violations in the whole process.

Cui Yuanjia nodded: "All inspections are carried out according to the original technical standards, and there is no problem with these engine technical data. All we can understand is to pass the technical standards inspection and conduct a comprehensive inspection to ensure that the quality of the assembly and parts is not a problem. Before assembly, each engine has also been tested on the ground test bench. The previous engines were inspected in this way..."

The introduction of the rd-33 engine has been quite a while.

China's various inspection processes are mature, which is related to national defense and security. Who dares to joke about it?

Xie Kai learned before that although Yang Chao was young, he was the most stable person in the entire test flight team.

It is absolutely impossible for old people like Tu Lang to perform various illegal operations. They will not fly without ground commands or dangerous actions, and there is no possibility of operating errors.

It is precisely because of Yang Chao's steadyness that the fighter jets equipped with a new batch of engines were first chosen to let the young Yang Chao take responsibility.

There was no problem with the previous test flight work. As a result, when the last asymmetrical configuration of the dragon raised its head and maneuvered before delivery, an accident occurred and crashed!

When the first batch of engine-assembled Super-7a was tested for asymmetric configuration subjects, the flying dragon also raised its head and maneuvered, and there was no problem.

Seeing Xie Kai pondering, Cui Yuanjia reminded him next to him.

"Xie Kai, according to the current situation of the Soviets, if they want to complete the delivery quickly, while ensuring the supply of MiG-29, the production speed has exceeded their production capacity. We agreed to deliver it, less than a month... In such a short time, quality is prone to problems. Even, it is very likely that the processing technology of some materials will be simplified... In this case, serious problems may also occur, and the results have not yet been produced in the physical and chemical analysis room..."

Huo Haiyuan and others have indeed considered these issues, but they think it is unlikely.

The Soviets delivered the engine.

The 200 engines delivered by the Soviets have not yet suffered any failures, but the service life is not long.

The engine delivered by the Soviet Union this time was used to assemble the MiG-29, the engine they used themselves!

The MiG-29 was equipped with its own air force by the Soviet Union, and it was even less likely to fail.

In a month, no one can produce so many engines.

In order to speed up the transaction with China, the Soviet Union gave priority to China, which was originally supposed to be used for the MiG-29, to urgently need the engine.

After hearing these introductions, Xie Kai said directly: "No matter what, I will react to the base leaders and ask them to contact the people from the Krimov Design Bureau immediately and ask them to send someone to investigate whether it was a crash caused by the engine... If there is really a problem with the engine, the fighter planes we delivered to Iraq must also be delivered."

A crash occurred, and all domestic over-7a were fully grounded for inspection.

The newly produced over-7a in Factory 132 also requires a comprehensive inspection.

The entire Super-7 project was shrouded in shadow when a fighter plane crashed.

If it is not resolved as soon as possible, it will cause a serious blow to the entire Super-7 projects.

Xie Kaike does not allow such a thing to happen.

"There is a problem with the rd-33 engine provided by the Soviet Union?"

Zheng Yucheng and Wang Guilin looked at Xie Kai in disbelief.

"Previously, the Soviet Union provided 200 engines. The fighter jets produced by us, and under the guidance of our technicians, did not find any engine problems or failures!" Wang Guilin reminded Xie Kai.

What Xie Kai said was too sensational.

If there is really a problem with the engine, thousands of rd-33 engines must be smashed into your hands.

Now 404 is short of money, but there is no money to waste on it.

"It's not that I have also tested it, and it doesn't meet the technical requirements." Zheng Yucheng didn't believe what Xie Kai said.

Too scary.

"At present, it's just a doubt. It's not necessarily the engine problem. The design and R&D team has analyzed it for so many days but has not found the cause of the failure. At present, we can only ask someone from the Krimov Design Bureau to come and help analyze..."

Xie Kai is not omnipotent.

He was not sure if the rd-33 engine had any fatal flaws.

Soviet engines have poor reliability and maintainability, which is far from publicly advertised data, especially the overhaul time.

Many of the first batch of engines introduced from the Soviet Union were already deactivated due to their long flight time and their service life.

Once there is a problem with the engine, the impact on the Super-7a will be disastrous and irreversible.

In the short term, it is impossible for domestic engine turbofan-6g to be equipped on the Super-7a fighter.

Since Xie Kai mentioned it, Zheng Yucheng and Wang Guilin attached great importance to it even if they didn't believe it.

Wang Guilin immediately contacted the Soviet Union and asked them to send technicians to assist in investigating the problem.

Order thousands of rd-33 engines, and once there is serious engine quality problems, there will be no cooperation in the future.

During this period, the Soviet Union was busy quarreling with the United States internationally, and it became more and more intense.

The world's attention is on both countries, and no one is concerned about a Chinese Super-7a crash.

Israel signed the first batch of fighter jet components with 404, which have been discharged and put into production at factories in the Soviet Union.

The first batch of Super-7a fighter jets produced by China have been delivered to Iraq, and the scheduled delivery time has passed.

The fighter jets have been assembled and have also undergone test flight testing. Various performances meet technical requirements, but China still did not hand them over to Iraq.

The just-appeared Super-7a crash forced China to suspend delivery.

The impact of the crash is great, and large-scale quality problems occur after delivery will have a serious impact on the entire 404 reputation.

The golden signboard that has been built over the years cannot be ruined here.

After production was completed, all fighter jets were parked on the runway outside the assembly workshop of Factory 132. The cause of the failure was not investigated clearly, and China would not deliver the fighter jets.

Even Pakistan and Egypt's -7a were also required to conduct a comprehensive inspection.

No fault hazards were found.

The Super-7a, which used the first batch of engines, was also completely grounded.

Iraq is anxious about China's delay in delivering the Super-7 fighter jet.

Iraq, the capital of Baghdad.

President Sha Damu's secret residence.

The president was looking at Ibrahim with a gloomy face.

Other senior military officials also did not have a good expression on their faces to Ibrahim.

Especially the newly appointed Minister of Defense Kachim, the newly appointed Minister of Logistics and Procurement Kamal, the Minister of Military Industry Kalam and other bigwigs from the President's hometown of Tikrit, as the president's most trusted military leaders, are even more dissatisfied with Ibrahim.

Ibrahim had reached a deal with the Chinese, and the money had been paid for several years, and the Iraqi military was still waiting for equipment.

As the Minister of Defense, Kachim is also the commander of the Republic Guard after being expanded and upgraded by the Tikrit Division.
