...The Phantom 4000 fighter, two engines were stopped at the same time, which was a serious accident. Omar successfully flew back to the airport in the lost power fighter, and thus made a second-class merit.

At the same time, the cause of the accident has also begun to be investigated in a intensive manner. This accident attracted the close attention of His Excellency Kusai. You should know that this type of fighter is his magic weapon to dominate the Middle East in recent years. He will never tolerate such fighter having major defects, especially the engine!

In dealing with this issue, Iraqi personnel and French Dassault technicians had a conflict.

The French firmly believes that there is no problem with its engine. The reason for the problem must be caused by improper maintenance of the ground staff in Iraq.

At this time, Iraq is no longer the Iraq without any industrial foundation. Iraq has dug back many experts from developed Western countries. Moreover, during the assembly of F-20 fighter jets and F404 engines in Iraq, Iraq has been secretly exploring the various technical means of these fighter jets and engines. Iraq has almost had a research team in the aviation industry.

After they came into contact with the advanced twin-rotor turbofan engine of the f404 engine, they raised many questions about the m53 engine of the Phantom 4000. This time, the Phantom 4000 twin-engine was parked in the air, verified some of their judgments. They firmly believed that the problem lies in the engine itself.

During the dispute between the two sides, the Phantom 4000 was also dismantled from the rear fuselage, removed the engine, and completely dissected.

Generally speaking, there are several situations for engine parking: the first type is oil leakage or oil pump failure, lubrication system failure, engine holding shaft stopping, and there is no possibility of restarting again; the second type is the compressor or turbine blade breaking, or internal bearings, housing and other important bearing parts blast; the third type is the engine surges or sucks into the wake of other aircraft or missiles, resulting in insufficient oxygen supply; the fourth type is the engine overtemperature, fire alarm and other reasons.

If in the past, French technical experts would have asked the engine to be transported back to France for dismantling and inspection, then the cause of the accident was entirely told by them. Now, the production line of the Phantom 4000 in Iraq is under debugging, and the production line of the f404 engine has already begun to be produced normally. With the insistence of Iraq, the m53 engine has been dismantled in Iraq.

The final analysis results came out. The compressor blades of the single-rotor m53 engine experienced early fatigue. This was not because of poor maintenance, but because the m53 engine was not suitable for the humid, salty seawater and very hot climates in the Middle East. When they were experimenting, they did not consider the weather conditions in the Middle East, so they inhaled in the air that had not been considered before and became unacceptable.

However, the compressor blades did not break, which shows that the engine was stopped in the air this time. The final result was that Iraqi experts looked at the common problem of stalling and panting in the compressor blades.

In fact, French technicians have already thought of this. They know that their engines have this congenital defect because they are single-rotor engines. However, they have been restricted by the telex system. This time, the aircraft did not enter complex aerial combat, but how could this phenomenon occur during the level flight?

The engine is the heart of the fighter. Since there is no conclusion on the engine problem yet, the Iraqi-equipped Phantom 4000 fighter was temporarily grounded.

After repeated discussions, Iraqi experts argued and finally formed the result: the accident was due to the lack of adjustments to adapt to the Middle East climate, which caused the early fatigue of the compressor blades of the engine. Although it did not look very powerful from the outside, it had already caused the unstable operation of this engine. When the accident occurred, the Phantom 4000 fighter encountered a vertical airflow during the cruise. Although the telex system was spontaneously adjusted, the flow rate entering the intake duct was significantly reduced, but the engine still caused a terrible pant shock. Finally, the parking in the air was stopped.

The second air start was successful, but the car stopped again, because of the problem with the compressor blades.

The solution is either to change the engine blades and make adaptability improvements at the same time, or to change the engine!

Improved engine blades and adaptability improvements will allow the fighter to be grounded for at least half a year to a year, because after the engine is improved, test flights and other work will be carried out again, which is a long task.

However, this plan was recognized by Dassault, because Dassault has no candidate engine.

However, Iraq will definitely not be satisfied with letting its powerful fighter stay on the ground for such a long time. Moreover, on their land, an excellent aircraft engine is being produced: the f404. The maximum thrust of this engine is only a few hundred thousand nh smaller than the m53. However, in terms of weight, the f404 is lighter, and it should be very suitable to be installed on the Phantom 4000. Compared with the m53, the fuel consumption of f404 is very low. Although the m53 is called a turbofan engine, the fuel consumption rate is not very high than that of the advanced turbojet engines in later generations. More importantly, the f404 engine has been used on the f20 fighter in Iraq and has confirmed that this engine can fully meet the climatic conditions of the Middle East.

Moreover, in this way, on the main fighter jets in Iraq, the light and heavy Phantom 4000 and F20 both use the same engine, which is very beneficial for logistics support.

Therefore, Iraq proposed to use the f404 engine to replace the not-very reliable m53 engine. All Phantom 4000 produced on the Iraqi production line are in this configuration.

This plan was strongly opposed by Dassault.

Originally, the production line exported to Phantom 4000 does not include engine production line. The eighty Phantom 4000 ordered by Iraq were produced in France, the first ten were produced in the middle twenty, and the middle twenty were assembled, while the back fifty were Dassault only provided engines and electronic equipment, and the rest were produced in Iraq. The price provided by Dassault was 15 million for each engine and radar. If Iraq did not import engines, then Dassault would have at least two million less profits per aircraft, and the fifty would have a profit of 100 million US dollars!

Therefore, Dassault firmly disagrees that the arms sales project to Iraq is the largest contract since its establishment, and they will never give up this opportunity to make money.

Both sides could not hold on and were eventually reported to Kusai.

Looking at the report, it coincided with Kusai's original idea. He made great efforts to introduce the production line of the f404 engine. He had this idea at the beginning. Now, there is indeed a problem with the Gallic fighter engine, but they do not want to give up this opportunity and will never agree to change to the American engine. It seems that they have to put some pressure on them!

Cusey immediately asked the secretary to contact the French side. He needed to communicate with Mr. Marcel Dassault personally about the Phantom 4000 issue. Originally, it would be possible to leave this matter to the project leader, but Cusey did this to show his importance to the project.

After two hours, Mr. Marcel Dassault finally arrived in front of the phone. The long-distance dedicated line called from Iraq made him feel very unknown. He already knew that the engine of the Phantom 4000 had problems in the Middle East.

Dassault actually attaches great importance to the project of Phantom 4000 in the Middle East, because Phantom 4000 has received funds from the Middle East to allow the project to continue and reach the point where it can equip the troops.

Although the first thing that was equipped was not the French Air Force, but Iraq in the Middle East, this further shows that this fighter has strong vitality. Dassault is actively lobbying the French Air Force, hoping to equip this fighter. At the same time, among other potential countries in the world, it promotes the most proud powerful heavy air combat fighter in Marcel's life.

Marcel remembered that the last time Cusey came to sign the contract, and at that time he thought that this man was an excellent military commander, an outstanding politician, and a shrewd businessman. Cusey knew what he needed, and the suggestions he put forward made the combat effectiveness of Phantom 4000 to a higher level. Such a person is now dissatisfied with the Phantom 4000 engine, and the weakness of Phantom 4000 is the engine!

"Mr. Marcel, the investigation results have come out about the engine parking accident in your country's Phantom 4000." Kusai talked to Marcel in English.

“Yes, we are actively improving our engines and providing solutions to use the Middle East environment.” Marcel also replied in English.

"This will take a long time, so we hope to use the f404 engine that my country can already assemble and produce for modification and production. All the Phantom 4000 fighter jets produced on the Iraqi production line will use this engine." Kusai directly mentioned it.

"Sorry, we have never been exposed to this kind of engine. Without various technical data, we cannot modify it. Whether the engine and the intake duct are matched, whether the freight control system matches the engine, and whether the flight envelope has been modified. If this is true, it may take longer." Marcel said. Although he is old and his brain is still very good, he casually put forward these very reasonable excuses. To be continued...
