"Let's go, let's go up." Standing under the Air Police 200 early warning aircraft, Li Zhiqiang said to Qin Xue.

This is an early warning aircraft that uses Yun-8 to transform, the body of this early warning aircraft is small, and the system is not as perfect as the air police 2000, but this early warning aircraft has an advantage, that is, the top is no longer a big plate, but a big stick.

The radar of the early warning aircraft is very particular about the installation position, and it is also necessary to determine it through repeated experiments.

At the beginning, I tried to install it in the belly, but as the radar got bigger and bigger, the space occupied on the belly would become larger, and in the end, it was impossible to place the landing gear, and then later, it was moved to the nose and tail, and the front and rear were a big bulge, and the hunting early warning aircraft was such a monster, but these were not the best solutions.

After arriving, after several developments, it finally became the most common way to place a large plate on the back of the aircraft, and the large plate was equipped with a radar, which can be said to be the most qualified solution.

However, with such a large plate, it has a great impact on aerodynamics, and the aerodynamic changes of the aircraft are obvious, resulting in a great decline in the flight performance of the aircraft.

Later, there was Faircon, with a big nose in the nose and two big cheeks on both sides, but there were also a lot of problems, so in the end not much was produced.

Our own Air Police 2000 uses a large plate, but on the Yun 8, we have made an attempt to change it into a long stick that runs through the front and rear fuselage, and is on the back of the aircraft by relying on the shelf, this stick can minimize the damage to the aerodynamic layout of the aircraft, and at the same time, it has also obtained a special name, called the balance beam.

This is not the first in China, in Sweden, first placed this balance beam on the Saab machine, it constitutes an early warning aircraft, Saab 340 early warning aircraft, in the international market, there is really a demand, it is said that many countries have a tendency to buy.

How can this stick be a radar for AWACS? Of course, we still have to start with phased array radar, the radar antenna has become a transmitting and receiving unit, which can be arranged into a disc or in other shapes, Fercom is this type, and this long stick, of course, is a compromise in order to fit the carrier aircraft, on both sides of the long stick, there are two rows of radar antennas, so that the situation in the 120-degree sector airspace on both sides can be monitored, and the 60-degree space of the nose and tail is formed.

It is not a full-range early warning aircraft, the monitoring area is not enough, however, in many cases, this will not cause obstacles, for example, flying in the airspace of their own country, monitoring the airspace of neighboring countries on the side, relying on the early warning radar on one side is enough, if you need to monitor all the airspace in all aspects, then the aircraft can fly an S-shaped route, you can achieve all-round monitoring, it is not complicated.

Moreover, the airspace monitored in this way is reduced, and the processing of data is simpler, which is a good choice for medium-sized AWACS aircraft.

Therefore, after the completion of the research and development of the Air Police 2000, the country has also begun the research and development of this kind of early warning aircraft, using its own existing Yun-8 as a platform, and the cost of this early warning aircraft will be lower, which is convenient for a large number of equipment and exports.

That's right, the early warning aircraft developed with huge sums of money is not only for domestic troops, but can also be exported to earn foreign exchange.

With the research and development experience of the Air Police 2000, this Air Police 200 is also handy.

Over the years, the two have spent too much time on the plane, and they have adapted to it, and they have completed the development of this project, and it is said that there is a new project below, which is the solution of loading a large plate for transporting eight, this large plate is a flat slit radar antenna, which can continue to reduce the cost, and it is also convenient for users to choose, which one to use.

"Well, here we are." Qin Xue carried a stack of thick materials in her hand, and followed Li Zhiqiang on the early warning plane, and other electronic engineering experts also went up one after another.

Inside the cabin, the equipment is densely packed, not only computer display, but also many electronic devices, the lid is open, in case of failure in the air, it can also be directly repaired on the spot.

They've got practice makes perfect.

The engines on both sides of the Air Police 200 roared, and the propellers spun, driving the plane off the runway and into the sky, and now, the time was afternoon.

Let's work!

Qin Xue calmed down and began to conduct engineering tests.

The AWACS aircraft flew into the sky and began to conduct tests, at this time, everyone did not know that in the sky, the climate was somewhat abnormal.

"The engine seems to be underpowered," said the co-pilot, who was also flying earnestly after taking to the skies, just after passing through a cloud of clouds.

"It should be the reason for the balance beam, don't worry, continue to increase the power." The captain said.

The roar of the engine became more and more intense, but it still seemed that the power was still lacking.

What's going on?

The captain looked at the instruments all over the front, and didn't find anything abnormal, could it be that the wings were icing? The wings have automatic electric heating, so they should be able to melt away when they freeze.

"Oh no, we're starting to drop height!" At this moment, the plane was getting heavier and heavier, and the engine was running to the maximum power, but it still couldn't stop the plane from landing, and the captain began to get anxious.

Pull up the plane, pull up the plane!

The nose of the plane began to tilt downward, the angle of the dive, became larger and larger, and in the cabin behind, the personnel who were seriously testing also realized that something was wrong.

What happened to the plane?

Li Zhiqiang's hand grabbed Qin Xue on the side, and at this moment, the eyes of the two looked at each other for a moment, and then, Li Zhiqiang hugged Qin Xue tightly into his arms.

The AWACS aircraft continued to fall downward, and on the plane, there were exclamations, not good, the plane was out of control!

The captain was still doing his best to pull up the plane, but it was useless, the plane was no longer controllable, and in his field of vision, the sky had turned into earth, a hill, occupying his entire field of vision.

Air Police 200 fell towards the hill, the wings were covered with thick ice, and the de-icing device of the wings actually had a failure that should not have occurred!

At this time, everyone in the plane realized that the disaster was coming, and as scientific and technological workers who have been fighting on the front line all year round, and as the developers of early warning aircraft, they have this preparation in their hearts.

At this moment, Qin Xue and Li Zhiqiang hugged each other tightly, but unfortunately, the research and development of this early warning aircraft was still not completed, which was the biggest regret in my life.
