Chapter 353 F-20 Returning to China
With the first flight of the F-20, the test flight of the F-20 is under intense development.
Four prototypes fly into the sky almost every day to detect whether various performance data meet the requirements.
At the same time, in order to repeatedly exert the glory of the F-5 and once again achieve sales performance in various places, it quickly puts into mass production. Northrop Company took a series of extraordinary measures to specially set up a production development center (pdc) to concentrate personnel on designing, producing and assembling F-20. At the same time, they used a large number of "hard" tools to facilitate the transfer of mass production.
Since the f-20 was originally developed based on the f-5, the test flight aerodynamic layout and other aspects are not the focus. After wind tunnel experiments, the f-20 did not have any defects in aerodynamic and flight control at this time. Therefore, the focus is on the subsequent installation of a fire control system verification machine.
The an/apg-67 radar, developed by General Motors, was not installed in the test flight until 1983, but orders from Iraq greatly stimulated them. As early as the first flight of the F-20 began, this radar was installed on the C-54 technology verification aircraft, and on the fourth prototype, the lead blocks used for counterweights were taken away, replaced with this radar, and connected to the b data bus.
Although it is necessary to open the weapon interface when saying it, it is actually very simple, because all US military aircraft are developed according to the general B data bus.
Before the 1960s, airborne electronic systems did not have standard general data channels, and connections between various electronic equipment units often required a large number of cables. At the beginning, it was not a problem, but later, as the onboard electronic systems continued to become more complicated, the cables used in this communication method would occupy a lot of space and weight, and the definition and testing of transmission lines were also more complicated and costly. It was not universal.
In order to solve this problem, the United States developed a standard signal multi-channel transmission system and announced the mil-std-standard in 1973. The b-channel multi-channel transmission data bus in 1973 became the technology that military aircraft will adopt in the future. It is a centralized time division serial bus with the characteristics of distributed processing, centralized control and real-time response.
This is like a telephone. There are many wires in the cable of the telephone line. Each time you make a call, different phone lines will be used between different users, resulting in huge communication lines. However, after using the same tcp/ip protocol, you can contact the whole world with only one network cable.
Therefore, to open the weapon interface to Iraq, you only need to open the internal code of the weapon control. Compared to mounting the C801 missile on the Phantom F1, it is much less difficult to mount the Matra 530 missile on the F-20 because they all have the same bus standards.
As for c801, it needs to modify its control software, and the workload is not the same.
The expert team led by Mr. Liang has been at the Basra Air Force Base in Iraq, and together with the team led by Joseph, overcome the technical difficulties of mounting C801 on Phantom F1.
The team led by Tu Jida was also specially allowed to join the others in front of a Phantom F1 day and night.
Advanced cockpit equipment, powerful radar and fire control system, and the friendship between human-machine interfaces have opened their eyes, especially when it comes to maintaining the engine, four ground crew members can lift the engine down within an hour with the help of special tools, which makes them even more eye-opener.
in the country, if you look at the sky from a well, you don’t see it. It turns out that foreign military aircraft have developed to this level.
What the pilots learned was that when they were fighting against Iranian military aircraft, they tried not to get into combat, but instead used the radar-guided Matra 530 missile to solve the battle outside the visual range, which made them even more refreshing.
All this made them feel that the proud J-7 in their hands actually had a lot of room for improvement, especially the creativity that Mr. Kusai said: redesign the front fuselage, make room, and install radar to allow the J-7 to gain medium-range combat capabilities!
After this improvement, it will definitely be welcomed in the international market.
At the same time, they are also looking forward to what will the Northrop F-20 imported from Iraq from the United States look like?
For some reason, His Excellency Kusai from Iraq is very friendly to their group. If a delegation from any other country is concerned, he will never be close to the most advanced fighter jets of his country.
However, His Excellency Kusai promised that after the F-20 arrived, they could visit it!
All of these things make Tu Jida, who led the team, sincerely thank Kusai.
In fact, when he went to Europe a few years ago, Tujida had already felt the changes in the combat style brought about by the advanced fire control of foreign warplanes. However, when he arrived in Iraq, he really felt what the air force of an advanced country should be like.
Using medium-range bombs to conduct visual-range outer space warfare will definitely be a major style in the future!
However, until now, the most advanced one that China has built itself, namely the J-8, has only close air combat capabilities. The J-8's nose is the same as the J-7's nose, and they are also the nose air intake, and they are improving it.
If Cheng Fei can obtain investment from Iraq and develop a new J-7 fighter jet, it will definitely be a sharp sword over the motherland!
Tu Jida has made up his mind secretly that after returning, he must do his best to let his superiors pass the proposal of His Excellency Kusai. Iraq will pay for money and make technology, and the two will jointly develop it.
Afraid of Iraq investing in technology? You should know that Iraq has even bought F-20 production lines. In terms of technology, people are much more advanced than their own.
No one of the delegations from China to Iraq were willing to give up the opportunity. They were mingling in the Basra Air Force Base day and night, studying hard.
Moreover, they felt more and more that the Iraqi air force was not as weak as the outside world said, with a bold and skillful style. This was clearly an elite army. Even when facing the powerful Tomcat fighter jets of the Iranians, they could still give it a try.
Thinking of the Air Force when the Army fought bravely in the border conflict three years ago? And here, they have already felt that the Air Force will definitely be the protagonist in the future war!
"I think it is very important for our fighter jets to install such precise inertial navigation, whether it is autonomous navigation or ground bombing, it is very important to have inertial navigation devices. Unfortunately, the things in this are too sophisticated, and the people here don't let us take apart." A voice said.
Tu Jida looked up and saw that it was the foolish boy who asked to watch F-20 during the last meeting: "Xiao Dangsheng, what did you say?"
"I mean..." He was about to speak, but suddenly, he was clamored by the huge roar above his head.
This roar... Xiao Dangsheng suddenly became alert. It was not the turbojet engine, but the turbofan engine!
Until now, the Iraqi Air Force still has no fighter equipped with turbofan engines unless...
Xiao Dangsheng put down the instruments in his hand and ran out of the hangar.
"This stupid boy." Tu Jida shook his head. This stupid boy is actually the person he values the most. He has a deep understanding of the avionics system and can be understood at one point.
Suddenly, he found that the others in the hangar were running outside the hangar, as if there was something going on.
"Tu Lao, the new fighter jet of the Iraqi Air Force, the F-20 has arrived, let's go and have a look." said a man.
Tu Jida looked up and saw that it was Mr. Liang.
F-20 has arrived? This is the first time I have seen a US-made plane! Tu Jida was also moved. No wonder Xiao Dangsheng ran so fast just now.
As soon as I left the hangar, I saw the landing plane at the end of the runway.
The pointed nose and huge vertical tail look like the Big One F-5 fighter.
It's indeed an Iraqi f-20.
The rear wheel of the fighter plane was released as soon as it touched the ground. They were already used to these. Iraqi fighter planes had very short take-off and skid-off distances, and they also saw some tricks from them.
At this time, two rows of soldiers were already standing guard on both sides of the runway, and these people from China could only watch from a distance.
However, this did not affect everyone's enthusiasm. They cheered hard, as if they were their own.
Zhang Feng stood at the end of the runway, but unexpectedly, the fighter planes would come back so soon, just like a dream. In the future, there would be no need to worry about not enough advanced fighter planes on their side.
There are four aircraft in total, which are four Northrop's low-speed pre-production models. The so-called low-speed pre-production models mean that there may be a small number of defects. Therefore, pre-production is first, and after the flight period, there will be no problems, then transfer to formal production.
Moreover, at this time, General Dynamics only implemented the initial function of the radar. Among the main air-to-air functions, the tracking edge scanning method also has defects, and the ground attack capability is not available for the time being.
In other words, these four fighter jets currently have limited air-to-air capabilities.
However, everything is temporary. After the next batch of aircraft arrives, the four aircraft can be upgraded.
Production in batches is also a practice in international military aircraft production.
The range of the fighter jets was not enough, so they did not fly directly from the United States, but were transported in a C-130 transport aircraft. And because Iraq was still in the war with Iran at this time, in order to avoid damage, they were first airlifted to Riyadh, then assembled the wings and flew to the Basra Military Region.
Random accessories, Iraq's learning maintenance personnel, and Northrop's technical assistance personnel were all transferred to Riyadh to take a vehicle and arrived one day later.
After the first two planes landed, they slowly slid towards the apron and opened the canopy. They were not Iraq's own pilots, but two foreigners.
Darrell stood in the cockpit, took off his helmet, and wanted to shout out his words to the crowd below: "hello, my friends!"
Before he could speak, he heard a huge roar coming from his head again.
A wave of air came over, destroying his golden hair style.
"** you!mr a!" Darral cursed, but the camera below caught his expression.
The second batch of two F-20s also began to land.
