In the workshop, a busy scene, the huge antenna is being slowly hoisted, and the most valuable parts of the entire pre-jing machine, except for the central computer, I am afraid that this antenna is it. Pen&Fun&Pavilion www.biquge.info{{}}

Inside the radome, there are three T/R antenna arrays, each of which is responsible for its own 120-degree area target.

Watching the antenna slowly hoist and finally stabilize to the base, the workers began to tighten the bolts on it and connect the various circuits.

"We have carried out complete wind tunnel experiments, and the installation of this radome has very little impact on the flight energy of the aircraft." Saber's engineer in charge of final assembly said.

The responsible officer of Iraq nodded and said: "Yes, I also believe that it will be able to fly smoothly, and our radome, which is liquid-cooled, is also a very correct choice." ”

Due to the high power of the radar antenna, the thermal power is also very high, and the Ericsson Eye is made into a hollow bamboo pole because it is a balance beam, and in the process of flight, you can use air cooling, but the number of T/R components of Ericsson Eye is three times that of the balance beam, and the power is also quite high, so it must be liquid-cooled. {{}}

The Soviets were also very helpless about Iraq's use of the Il-76 as a platform to modify the pre-jing machine, because the Soviet Union's A-50 pre-jing machine was advanced at this time, and they had just equipped the troops, so it was absolutely forbidden to export equipment, and the Tu-126 pre-jing machine Iraq did not look down on, and the Soviet Union acquiesced in Iraq's modification of the transport aircraft, but did not provide any form of technical support, and all the improvement work needed to be carried out by themselves.

This chapter is a maniac hand-hit) and this aspect, is the strength of British Aerospace, the internal main computer, cāo console and other equipment, are developed by the aerospace company and Ousheng company, at this time, Ousheng company, has been in the research and development of electronics, has a wealth of experience, Ousheng company's latest production of liquid crystal display, also used in the internal cāo console. In addition to these devices, there is a weather radar installed in front, a radar for navigation and mapping under the nose, as well as data links, electronic warfare equipment, etc. All system integration was carried out at Saab.

It is conservatively estimated that after two or three years of test flights, Iraq has overcome various problems such as electromagnetic compatibility and can enter service with the Iraqi Air Force in the early 90s, and by that time, Iraq will need to be equipped with at least 6 to 10 of these large pre-aircraft planes.

In later generations, due to the lack of installed objects, the Ericsson Eye project progressed slowly, until the mid-nineties, it entered Brazil in South America, and finally achieved positive results, and now, the pre-jing machine of this situation has entered its own life period in advance, and on this, Iraq has even caught up with the United States.

While Iraq's pre-aircraft project is progressing smoothly, other cooperation projects between Iraq and Sweden are also progressing steadily, the most important of which are the active Sky Flash Missile and the AIP system.

Active sky flash, that is, to replace the seeker of Iraq's current sky flash missile with an active radar seeker, compared with the current passive seeker, that is, its seeker can send shè radar waves, so it can also attack targets without the radar of the carrier aircraft, although limited by the size of the radar antenna, resulting in very small power, can only be guided at a distance of about 20 kilometers, but this can also allow the carrier aircraft to leave the battlefield early in the final stage, or turn to attack the next batch of targets, Very practical. At present, this missile has entered the stage of hitting targets with live ammunition, and after the problems are exposed by experiments and improved, it can be successfully finalized and entered into small batch production. And, on this basis, the Saber company proposed a new project of an active missile with a range of up to a hundred kilometers, using a ramjet engine, which received the attention of the Iraqi side.

On the other hand, the AIP system, the technology has begun to mature, after further investigation, the Iraqi Navy personnel decided to order a set of such systems, installed on a TR-1700 submarine in Iraq, the modification work was carried out in Iraq's own shipyard, cut this submarine, add a section of the AIP system, wait until six months to a year of sea trials, after evaluating the effect, and then consider the other three for the same modification, and consider, if fully applicable, and safe, New specially designed AIP systems were purchased from Sweden, and the Swedes named them Gotland.

Sweden's system, when designed, is used to modify existing diesel-electric submarines, due to the high-intensity use, the first two TR-1700 submarines, the battery has been somewhat aging, this modification, by the way, the battery can be replaced, and this modification, also got the help of German experts. {{}}

In 1987, the world was still moving forward in the rolling flow of history, and everything was still developing according to the original historical trajectory in the regions that were not affected by the butterfly effect of the Qusay crossing.

The sky was clear and cloudless, and it was a good day to fly, and at Helsinki Airport, Finland, a nineteen-year-old young man from the Federal Republic of Germany, Matthias Rust, an amateur flyer, was making the final preparations for take-off.

Rust is an avid flyer and a member of the Hamburg Aero Club of the Federal Republic of Germany, with which he flew from the port of Hamburg in the Federal Republic of Germany to Reykjavík, Iceland, and then to Bergen, Norway, and Helsinki, Finland, where he has recorded less than 40 hours of flight time.

Rust has loved the blue sky since he was a child, and he has learned to fly an airplane at a very young age, thanks to his father, because his father was an aircraft dealer, and the main product he distributed was the "Cessna" light single-engine sport aircraft. {{}}

However, Rust's ambition is very ambitious, when he was a child, he wanted to do something to make the world remember his name, so flying a plane through the Arc de Triomphe in Paris or landing on Red Square are his two goals, but the plane through the Arc de Triomphe has been taken by others, therefore, if you want to make him famous, then, the latter way, is very much the idea of building Xingxing.

At a time when the East and West are in a serious standoff during the current Cold War, flying an airplane and being the first person to land on Red Square will certainly attract the attention of the whole world. Of course, his purpose in doing this was to bring the friendship of Western Europeans to the Soviets.

For this flight, Rust made a lot of preparations, his plane, just a small single-engine sports plane, with limited space time and insufficient range, so, he did it himself, removed all unnecessary equipment to reduce the weight of the aircraft, and the seats inside were also dismantled by him.

This kind of aircraft has a range of 1,000 kilometers at an altitude of 2,500 meters, but this time he will fly at an altitude of about 30 meters, so the fuel is definitely not enough, so he deliberately added a set of additional fuel tanks to meet the needs of this flight.

Today, the opportunity has finally arrived.

"Helsinki, rookie 172 requests to take off." Rust shouted over the radio that Rookie 172 was his radio codename.

"You can take off, pay attention to the course and speed, I wish you all the best, rookie." The sound of the tower was heard over the radio.

Rookie? His name will soon be resounding all over the world, and Rust started the engine after sixteen maneuvers according to the requirements of the training.

The propeller in front of him spun faster and faster, and finally, working properly, he turned off the stop brake in front of him, and the small Cessna began to glide down the runway.

This kind of aircraft is simple, easy to use, and the flight ability is also very stable, and is used by many aviation schools as a primary training aircraft to train pilots.

Like a light swallow, the plane slid to a third of the runway, and then pulled up the nose and flew into the air.

Looking down on the earth from the air, all the scenery is so beautiful. This is also what makes many people love flying.

It was just an ordinary training flight for a rookie pilot, and the traffic control officer on the tower took a look at the point of light and stopped paying attention to him.

However, who knows, the plane flew for only a few minutes before making a sharp turn to the southeast, and then the bright spots that showed the plane on the radar phosphor screen quickly disappeared.

"Rookie 172, please answer when you receive it."

"Rookie 172, please answer when you receive it."

There was no response, and no distress calls were received.

Oops, this rookie must have fallen into the sea when he flew alone. In accordance with the principle of emergency search and rescue, they immediately contacted the military, and the military urgently dispatched three helicopters, four warships and 17 divers to search and rescue the sea with oil stains, but found nothing.

This young man may have been eaten by a shark.

The news came back to Rust's home, his parents were devastated and devastated that just last night, they also received a call from Rust, this flight training was over the day after tomorrow, and he would be able to return home, but, unexpectedly, there was an accident!
