The blue sky is endless, there are a few white clouds floating, and the sky has been beautiful recently, and the weather is always so sunny and good, and the test flight work of the fighter plane is going on non-stop.

After the first flight of the new F-20, the main verification is whether the aerodynamic layout is reasonable, because this is originally a modified aircraft on the F-5, so the aerodynamic layout has been very suitable, but the two sides changed to a single engine, in order to adapt to the F404 engine, the air intake has been redesigned.

Although it does not adopt the now popular edge wing and other technologies, Northrop is also making small changes, and the No. 2 aircraft has added an expanded forward extension wing on the basis of the original wing, which is somewhat similar to the characteristics of the edge wing, which can increase the lift at large angles of attack and expand the range of angles of attack of the F-20.

The No. 3 aircraft has been added with a full set of avionics equipment, mainly for test flights to develop avionics equipment for the F-20.

While the test flight work is underway, Northrop is already preparing for the mass production of this fighter, because the test flight is going well, and the first low-speed production version of this fighter will soon enter the low-speed production stage.

And for future production, Northrop has set up a production development center to concentrate personnel on the design, production and assembly of the F-20. In this production development center, there are a number of Arab employees, all of whom are technicians sent by Iraq to learn how to assemble so that the production line can be quickly produced after returning home.

At the same time, Northrop is revamping the production line of the old F-5 in order to be able to transition to the production of the new F-20 fighter.

In addition to production, Iraq has sent several pilots headed by Hamad, who have been moving up and down, hoping to fly the F-20 fighter as soon as possible, but now the test flight schedule of the new aircraft is full, where is there time for them to use.

Fred had an idea, since they wanted to fly so much, then fly! Not on a real plane, though, but on a flight simulator.

As early as when the F-20 was designed, in order to verify the layout of the cockpit, in order to train test pilots in advance, a model made of the F-20 cockpit according to 1:1 came out, and through the computer, a large display in front of the control was used to show the field of view of the flight, so that the pilot could familiarize himself with the pilot's flight in advance.

Who knows, those Arab pilots, who really have a lot of endurance, entered the intense "training" on that simulator. God knows what they think, it's just a simulator!

Only Hamad knows that His Excellency Qusay sent him out, that is to learn how to fly this fighter, and now he wants to start flying, it is impossible, but time waits for no one, the Iranian Tomcat has always been a lingering shadow in his heart, although the Mirage F1 can use the medium-range Matra 530 missile, and has the ability to fight Tomcats at a long distance, but if it falls into close combat, it still can't escape the fate of being shot down.

The Tomcat is too good, with a good aerodynamic layout, a high-thrust engine, especially a variable sweep wing, and a close combat with a Tomcat, almost all of them are looking for death.

However, the F-20 is different, although the original purchase of the F-20, also looked at the medium-range interception capability, try not to get caught in the fight, but if you accidentally enter the fight, although the F-20 is a single-engine light fighter, thanks to a powerful engine, the thrust-to-weight ratio of the whole aircraft is more than 1, the Mirage F1 is definitely unattainable. So, the F-20 still has a good chance.

It is Hamad's greatest wish to become familiar with the F-20's work as soon as possible, and when the F-20 is equipped with the Air Force, to form combat effectiveness as soon as possible, and this is the purpose of his visit. So, even though it's just a flight simulator, Hamad and his colleagues are still training meticulously.

Their spirit has made the people who originally despised Iraq begin to respect it, and it is not difficult for this country to take off with such people! They remembered the ancient civilization of the East, and their people united and struggled, didn't they build an industrialized country in the same way? They can, this people in the desert, too.

Basra, another group of people is also busy.

The team led by Joseph has not made much progress, and he also knows that if he wants to develop qualified jamming equipment, even in Europe, it is a difficult hurdle for a large team to overcome.

Be sure to succeed! Although Joseph loves to travel and ancient buildings, he also loves electronics, and when he gets into it, he will feel very fulfilled, and when he overcomes difficulties, he will have a joy that cannot be extricated.

And the young Arabs and engineers under him are also working very hard, trying various solutions.

Electronic interference is the application of amplified power of electromagnetic waves to interfere with the other party's electromagnetic signal, which requires frequencies to be close, and to interfere with different electromagnetic devices, that is, different electromagnetic frequencies are needed, that is, his interference signal needs to be in the full frequency band.

Moreover, in order to interfere with and suppress the other party, that is, the strength of the signal transmitted by the other side is far greater than that of the other party, and more power is required, and at the same time, in order to be easy to carry on the aircraft and make the situation of the pod, it is necessary to have a smaller volume, even on the ground, in order to facilitate maneuvering, it needs to be installed on the jeep, and this jamming equipment also needs to have a light volume and shape, the most suitable parabolic antenna, which cannot be installed.

All of these are issues that need to be solved. It takes a lot of experimentation, perhaps, and luck.

Joseph was not discouraged, and was still thinking about various ways to use these electronic components imported from Europe at a large price, through combination, to obtain a powerful function.

Just when the mountains and rivers were at the end of the mountain, a fortuitous coincidence suddenly gave Joseph an inspiration.

Since Joseph was already in charge of the avionics system, the electronic equipment of all the fighters on the airport was not a secret to him, and when he was solving a problem with the avionics equipment of the Mirage F1 in the hangar, another MiG-23 in the hangar was also disassembling the avionics equipment.

When the other party opened it, Joseph just glanced at it, and this glance, surprise, exclamation, inspiration, all came out.

Transistors, integrated circuits, problems that can't be solved, can be completely used with tubes!

Due to France's advanced electronic technology, France's avionics equipment has almost eliminated the electron tubes that consume a lot of power and have low energy.

The tube looks like a small light bulb with complex vacuum electrodes inside, which were the main components used when electronics were first introduced.

With the advancement of technology, especially the discovery of one-way conductive electrical surnames of semiconductor materials, electronic components, almost all of which are manufactured with semiconductor materials.

The emergence of transistors is a brilliant and colorful wonder blooming on the tree of electronic technology. Compared to electron tubes, transistors have many advantages: the building blocks of transistors are not consumed. The life span is generally 100 to 1000 times longer than that of an electron tube, which is worthy of the reputation of a permanent surname device. The transistor consumes very few electrons, consumes less energy, and the transistor does not need to be warmed up, and works as soon as it is turned on. The transistor is strong and reliable, 100 times more reliable than the electron tube, and is resistant to shock and vibration. Later, integrated circuits that combined multiple transistors appeared, and the circuit components were fewer, and the reliability was further improved.

Later, the development of electronic technology contributed to the birth of the online world in later generations.

However, electron tubes were still widely used in the Soviet Union, because the transistor has a relatively small ability to withstand the impact of electrons in a nuclear explosion and will not be damaged by sudden electronic impulses, that is, the power that the tube can withstand is greater!

If the electron tube is used to manufacture the key parts, then the power of the interference equipment will be at least 100 times larger than the original!

After Joseph helped overhaul the electronics of the Phantom F1, he immediately rushed back to his laboratory, led the research team, and started a new research.

After several days of hard work, a peculiar jammer was finally developed.

The volume is the size of two large suitcases, and while using transistors and integrated circuits inside, there are also more than 20 transistors scattered inside, and the antenna is like a hedgehog, on the antenna of a backbone, more than a dozen are scattered in all directions, which can spread interference to all directions, and the preliminary design can interfere with signals within 50 kilometers.

Joseph applied for a jeep, mounted the jamming equipment on the jeep, and at the same time, carried a small generator set, such an jamming device, the power consumption, reached ten kilowatts, and the transmitting power was one kilowatt.

(The power of the jammer is not large, and the power of the airborne jamming pods of later generations is only about a few hundred watts, but it can already jam the enemy's radar within a hundred kilometers.) In order to prevent the jammer from affecting Basra after it was turned on, Joseph led the experimental team to the desert west of Basra.

It's already a hundred and fifty kilometers away from Basra, so in this case, it shouldn't interfere with the normal operation of Basra, right?

Joseph started the generator set and began to warm up the jammer.

Eventually, all the tubes inside turned red, and Joseph activated the interference.

Suddenly, there was a strong interference sound on the radio, and except for the characteristic noise, no matter what was said, it could not be heard.

At the same time, the radio equipment of another jeep, which was placed a hundred kilometers away here, was also strongly interfered with.

At this time, Joseph did not know that not only a hundred kilometers away, but also Basra, a hundred and fifty kilometers away, was also disturbed, but fortunately the airport was notified in advance today and the emergency plan was activated, so there was no major accident.

This perverted jammer is actually one hundred and fifty kilometers away, and it still has a strong effect!

When Zhang Feng learned the news of the successful development of the jamming machine, he finally knew that the time to launch an attack was approaching.

Joseph's jammer was successfully developed, and the next work was to change the volume of the jammer, redesign it, make it into a pod, and hang it under the belly of the MiG-23.
