To search for underwater submarines, you need sonar equipment. Various sonar buoys are continuously thrown downwards. At the same time, you must carry torpedoes and other equipment, which can be thrown down when critical.

In this way, fixed-wing anti-submarine aircraft are in great demand. However, this type of aircraft is technologically advanced and only a few countries can manufacture it.

Han Guo suffered a lot because of the lack of such anti-submarine aircraft.

The next day, we arrived at the location of the hunting fan anti-submarine aircraft, and everyone began to investigate this aircraft.

Because it was modified from a Comet airliner, the shape of this aircraft is very similar to that of the Comet airliner. Especially the layout of the engine is at the root of the wing, which looks like an animal’s nostrils. A huge noise is introduced into the body, so later generations have been eliminated.

Since its engine uses Spey, and Han Guo has already started to produce Spey engines, this can greatly facilitate logistics maintenance.

Due to the change to the anti-submarine type, it has added a variety of equipment, such as a magnetic anomaly detector installed on the long tail beam at the rear of the tail, a search radar installed on the nose, and an electronic support system antenna installed on the vertical tail. and many more.

The navy personnel watched with enthusiasm, and the personnel from the Niu country were also very enthusiastic. Yesterday the other party made the decision to purchase a supporter-class submarine easily. The price was also quite favorable, which encouraged the personnel of the Niu country with enthusiasm.

Major General Wu Huade still followed, introduced by the pilot, and the various equipment was praised by everyone.

On the tarmac, Qin Guan slowly stepped off the plane, watching too much, dazzled, this kind of plane, it is enough to introduce two, the key is to introduce the technology, and then use his own Yunba platform, you can The same anti-submarine patrol aircraft was restructured.

As soon as he got off the plane, he heard a roar in the distance. An airplane was flying from the sea, aiming at the runway of the airport, and slowly landing.

When seeing this plane, Xiang Jing beside Qin Guan couldn't help but say: "It's ugly."

Xiang Jing is Qin Guan's bodyguard, and generally does not participate in specific negotiations. But now, when he saw this aircraft, Xiang Jing still expressed his own sigh. He had never seen such an ugly aircraft.

Similar to the Lie Mi anti-submarine aircraft, the engine on the wing root of this aircraft is already very ugly. Compared with the Lie Mi anti-submarine aircraft, this aircraft has a big nose protruding in front. This big nose is almost catching up with the whole aircraft. With the size of the head, it protrudes downward, like a liar puppet with a long nose.

At the same time, at the end of the aircraft, a thick tail vertebra was dragged, as if a big hemorrhoid came out of a chrysanthemum, how ugly and ugly.

Xiang Jing's aesthetics are not harsh. In the past, when he was in the special forces, mud and everything could be smeared on his face, and any poisonous snake could be considered delicious. You can see how ugly this thing is.

This strangely shaped airplane is ugly enough, of course, Qin Guan also knows the reason why it is ugly.

Because it is an early warning aircraft.

The early warning aircraft is improved on the basis of transport aircraft or passenger aircraft, but compared to the original aircraft, the addition of radar equipment will cause a great change in appearance.

For example, the Eagle Country’s early warning aircraft all have a large plate on the top. In this large plate, there is a radar antenna with a flat plate slot. In later generations, they even changed to a phased array radar antenna. There is no need to turn it. The form of the big plate has always been fixed.

But Niu Guo, until now, has not overcome the difficulty of processing flat-slit radar antennas. They still use ordinary pot cover antennas, and it is not easy to install them on the plane.

Therefore, Niu Guoren thought of a new way.

Simply separate the radar, install an antenna on the nose, and an antenna on the tail. If you want to be an early warning aircraft, the antenna must be much larger than that of an ordinary fighter, so this has become the current situation.

Inside the big nose and the big hemorrhoids at the tail, there is a large pot lid radar antenna.

Niu people have always been mavericks. In this way, searching for one hundred and eighty degrees in the front and one hundred and eighty degrees in the back is more than enough.

However, the body is limited. They did not use a big guy like the Boeing 707, which is the original Comet passenger plane. The internal space of the body is limited and two sets of radar circuits cannot be inserted. Therefore, the two antennas share a transmitter.

This leads to another terrible situation.

Sharing a transmitter, controlled by the waveguide switch to switch on alternately, this thing, controlling such a powerful current, often burns.

The ignition controlled by the switch circuit is quite strong. Once it burns out, it takes several hours to repair.

At the same time, the data processing capability is not strong, which caused the aircraft to have continuous failures during the test flight, which could not be eliminated, the performance was not up to standard, and the ground clutter could not be filtered. In the end, the project was discontinued. They honestly purchased the E-3 from Eagle Country. Up.

Now, this aircraft has just been manufactured, and it is in the early stages of the test flight. Qin watched the aircraft with a good mood.

This is a project that is destined to be impossible to complete.

Sure enough, after the plane landed, the people inside fell down in frustration. A person in his fifties shouted: "Spare parts, replace them with spare parts. We can have a test flight in the afternoon. God, don't torture us anymore."

"Old John, what's the matter?" At this time, many technicians from below greeted him and said immediately, watching him crying.

"The traveling wave tube burned again, and the circuit boards were burned out. We used three fire extinguishers to put it out."

At this time, everyone saw a lot of wet marks on his clothes, which seemed to have been covered with fire extinguisher foam.

This kind of test flight is risking life and death every time.

Then, he also saw Qin Guan here, and he was taken aback. This person, a famous man, actually came to this base?

The other party came to see the hunting fan anti-submarine aircraft? Yes, Han's anti-submarine equipment is quite backward. However, Han's airborne radar technology is very advanced. In the air show these days, their planes are all equipped with flat-panel slot radars.

If you can get this kind of technology, that would be great!

Thinking of this, he had already stepped down and came towards Qin Guan's direction.

The navy personnel are still studying the hunting anti-submarine aircraft, but Qin Guan smiled and looked at the incoming person. This guy was sent to the door.
