With regard to the new early warning patrol aircraft, after the investigation and study of the General Staff and the Navy research group was completed, the preliminary work has been carried out, and people from all walks of life are gradually in place, and the 603 retired veteran technicians coordinated by the General Staff Department heard that the state has relaunched the early warning aircraft project, and naturally happily agreed to participate in the project.

In fact, the old scientific research and old technology that have just retired will be a little uncomfortable within a year or two after retirement, and the originally busy life will suddenly become idle. In addition, after nearly 10 years of early warning aircraft research and development work, in the end, they got off the horse and forgot about it, and everyone has regrets in their hearts.

Naturally, these old technologies came to the Southwest Science and Industry Bureau, became glorious retired and rehired personnel, and once again began the development of new early warning patrol aircraft.

As for the external bidding, Yang Hui has not made it public for the time being, and he has to wait for the news from Iran to be finalized before it can be implemented, and now he is only sending bidding news to Grumman and British Aerospace.

When the new AWACS project began to be launched, good news came from distant Pakistan, and a new Jianjiao-7/Jian-74 production and assembly line was completed in Pakistan's original Jianliu 6 repair plant.

The first batch of two J-74 aircraft parts packaged and sent by Southwest Science and Industry have arrived in place, and the production line slowly began to operate under the guidance of the engineers sent by Southwest Science and Industry.

"Your Excellency, our J-74 aircraft is very easy to produce, except for engines, avionics, radar, all components can be manufactured by Pakistan within five years, I believe this will be another milestone in the development of Pakistan's aviation industry."

The assembly of the first aircraft began, and the factory was located in Islamabad, so it was only natural for the president to come and see it. This is a groundbreaking event for Pakistan, and it is also something that he is proud of as a president.

Watch as the airplane fuselage frame segment is fixed. Various trusses for load-bearing are placed in designated positions, and these trusses and bulkheads are fastened together. The general frame of the fuselage of the aircraft will be formed, and then the skin will be riveted to form a cylinder.

Then there will be various wiring in the barrel, the arrangement of pipes, etc., as well as fuel tanks and other on-board equipment placed in the middle of the fuselage, which is the aircraft fuselage, and then the wings manufactured in another workshop will be transported to the assembly workshop to complete the docking.

The flat tail and vertical tail are all installed on the plane step by step, and the most important landing gear is also installed at this time, only after the landing gear is installed. The aircraft can be considered to be completed, and the pure mechanical manufacturing part is roughly completed.

The engine compartment is the best quick-release structure in the aircraft, and it is usually installed after the entire aircraft is manufactured.

When the mechanical part is manufactured, it is the turn to install the on-board equipment, such as radar, cockpit avionics, etc. At this time, the installation of electronic equipment is different from the mechanical part, and it will be dragged to another workshop, where specially trained electronic equipment assembly workers will install electronic equipment.

When these electronics are installed, this phase of the aircraft is called the 'Green Plane' (don't ask why it's called, I don't know). This is due to the fact that the aircraft was not painted at this stage, and it is said that the aircraft was already finished at this time.

At this time, the airplane, in essence, is just a simple flying tool that can fly. However, it has not been able to complete the tasks required for the use of this aircraft, and the aircraft at this stage is more like a ship that has just been launched and has not completed its perching load.

In order for the aircraft to continue to be built, some auxiliary equipment needs to be installed. to help him accomplish his mission. Fighter jets need to be equipped with weapons, such as aerial guns; Reconnaissance aircraft need to be equipped with reconnaissance equipment. Or other large special operations aircraft, such as AWACS, need to be pulled for special modifications. Equipped with radar and command system.

If the business airliner is delivered at this stage, the aircraft can already fly to the designated place for test flight, in order to obtain each aircraft's own unique airworthiness certificate (similar to the car's operating certificate), and install the specified auxiliary airborne equipment: seats, auxiliary power systems, escape systems, interiors, etc.

Even if such an aircraft has completed the whole manufacturing process, as for the problem of painting, it is the simplest point, whether it is military or civilian, painting is the least to consider. Some of the planes used by the army are delivered directly without painting, and are sprayed by the combat units themselves.

Now the J-74 is still a period of time away from completing these, especially when the production line has just begun to be used, more cautiously, and if you don't pay attention to the wrong installation, it may be a big trouble, many parts in the aircraft can not be dismantled after installation, and you must be cautious in the manufacturing process.

These are certainly not the president's concerns, what he needs is to go to the scene, encourage the factory workers, technicians, thank foreign technicians, and play the role of spiritual leaders.

"Yes, the friendship between our two countries is tempered from blood and fire, this J-74 aircraft is a testimony to the friendship between our two countries, I believe that when this aircraft soars in Pakistan's territorial airspace, Pakistan's airspace will be unbreakable."

Unbreakable airspace? This is still a little doubtful, but it should be barely used to defend against the third brother, maybe the early warning patrol aircraft can give Pakistan a few at that time, anyway, Pakistan's land area is small, and there is no need to worry too much about the range, and it can also be used with J-74.

Yang Hui was not here, but the completion of the construction of Pakistan's production line had already arrived on Yang Hui's desk, and the $100 million loan he borrowed from Saudi Arabia was originally intended to be offset by the profits of this project, but later because the country wanted to continue to develop J-74 and J-75 on the Jianjiao 7 project.

When the Jianjiao 7A was developed, the $100 million borrowed by the Southwest Science and Industry was handed over to the state to fill in, and the country at that time was very generous because of the profit from exporting missiles.

That is to say, now the profit of nearly 100 million US dollars does not need to be offset against the Saudi loan, and it is completely the funds for Southwest Science and Industry to build this production line, export technology, and train Pakistani technicians.

Now Yang Hui is picking up the phone and chatting happily with Sultan, Pakistan's production line was established by Saudi Arabia, and now that the project is completed, it is time to pay the final payment, and Southwest Science and Industry is now relatively short of money.

"Yes, yes, Pakistan's production line has been completed, the first batch of J-74 parts have arrived, and the plane will be off the assembly line in two months, this production line is absolutely world-class, and our production line in Southwest Science and Industry is not comparable to it!"

Can it be compared! The first fighter production line in the Islamic world funded by the local tyrants is not the most advanced construction, but the southwest science and industry responsible for the design and construction of this production line has also gained a lot in addition to money, not only has the experience of establishing a world-class production line, but also has the opportunity to import a number of advanced production equipment.

Hearing that the production line has been completed, Sultan is also very happy, after all, our Islamic countries still have their own aviation industry, when the Arab countries united to establish the Arab United Aviation, established in Egypt, a country with a good industry, but now it seems that the proximity is still not as fast as Pakistan's development.

"That's really good, rest assured, as long as there is no problem with the plane off the assembly line, our final project balance will be in place, and Saudi Arabia will definitely not make a mistake on the issue of money."

Hearing that the money was going to be in place, Yang Hui said that he was very satisfied, and various projects were waiting to be used: the DSI air intake and the new early warning patrol aircraft were all projects that cost money to produce results. (To be continued.) )
