As long as the agreement is signed and there are no major international problems, the United States will not obstruct it this time, because Zhang Feng has made great contributions in rescuing the hostages, and the Americans will also have a good impression of Iraq and export this kind of engine production line. It is a way to enhance the relationship between the two countries, and it can be understood by the people.

As for General Motors, as long as there is a high price, they are willing to export, because, with the completion of the development of their high-thrust F110 engine, this kind of medium-thrust engine will not pose a big threat to them.

It's just that they didn't expect that the cunning Iraqis would get mixed up with the Chinese. Using these advanced processing equipment, a few years later, they successfully finalized the turbofan 6 high-thrust engine developed by the Chinese and put it into production. use.

Afterwards, Zhang Feng met with the president again. After several hours of talks, the president agreed with his proposal, and kept silent about the fact that the Iranian Air Force had suddenly become stronger. , Moreover, these hostages have entered Iraq, and they are flying back to Baghdad in a helicopter sent by the Iraqi Air Force!

In Baghdad, the hostages received warm condolences from senior Iraqi officials including President Saddam Hussein. While giving them concern, they also condemned the behavior of the Khomeini regime in Iran that blatantly trampled on international morality and supported terrorist activities!

Subsequently, all the hostages were transferred to a special plane of Air France and flew back to the United States, where President Reagan was already waiting for their return.

The hostage incident, which lasted nearly two months, finally came to a successful conclusion.

Chapter 371 Phantom 4000

Dassault Flight Test Center in Marseille, France.

A twin-engined fighter plane quietly stayed at one end of the runway. Compared with those planes on the tarmac, although they looked very similar in appearance, as if they were one size bigger, there were also obvious differences, that is, A pair of rotatable canards are added to the front end.

Although in 79, this fighter plane began to conduct test flights, but after talking with His Excellency Qusay, Marcel's vision broadened again, and he did not hesitate to waste any more time to carry out a new shape design. The key is that Movable canards.

The amount of vortex caused by the canard, the size of the area, and the appropriate distance from the main wing, all of which need to be blown through the wind tunnel to know.

And the DSI inlet proposed by His Excellency Qusay, after passing through the blowing hole, proved to be not very suitable, but this movable canard is something that can completely change the maneuverability of the fighter!

A very troublesome problem for delta-wing aircraft is that the take-off and run distance is too long. The Phantom 3 needs a runway of more than 1000 meters. This is why the Phantom F1 later adopted a conventional aerodynamic layout. What a benefit the company brings, because Dassault is best at the tailless delta wing!

By adopting new technology, high-thrust engine, fly-by-wire flight control, relaxation and stability of these new measures, Mirage 4000 will have a rapid change compared with its predecessor.

Now the Mirage 2000C production model has started production, and it is expected to be delivered to the Air Force next year. Dassault’s main technical force is also concentrated on the Mirage 4000, especially the addition of movable front canards, which leads to the flight control of the fly-by-wire system. The law needs to be redesigned, and the designer's understanding of the canard is not very good, so everything is in the process of groping.

In this way, the test flight is more risky.

The test pilot is Dassault's most famous Bill, and he is making preparations for the flight methodically in the large bubble cockpit.

Since Phantom 2000 and Phantom 4000 have 80.00% commonality, the current cockpit is basically similar to that of Phantom 2000, with the same layout, there is only one screen at the front and bottom, and some instruments on both sides. With a larger radius, even the cockpit looks wider.

Standing on the runway, Marcel was full of emotions. This was arguably the last project in his life. He was already gray-haired, and he was looking forward to the successful test flight of this heavy-duty air superiority fighter.

The canopy closed slowly, and Bill stretched out his thumb in the cockpit to the distant crowd on the ground, and then, with the help of the ground vehicle, started the two engines.

After the ignition was successful, Bill checked the front instruments, looked at the straight runway, and said calmly: "Tower, No. 1 requests takeoff."

Marcel looked at the plane on the runway, the ground taxi test has been completed, this time, it is the real take-off!

Receiving a reply from the control tower, Bill did not turn on the afterburner, but only adjusted the accelerator to the maximum, released the brake, and the huge Mirage 4000 began to slide on the runway.

Soon, the estimated take-off speed was reached, and Bill pulled the control lever backward.

Immediately, he felt a huge force coming, surging. Under the thrust of the powerful engine, the lift generated by the huge wings, and the prying of the duckling wings in front, the Mirage 4000 was sharp. Lifted the nose of the aircraft, and then, pointed directly at the blue sky!

At this time, the sliding distance is only 500 meters, and this is without afterburner!

Marcel looked at the eagle taking off with expectant eyes.

At the moment of flying just now, the duckling wing played a very important role. Its rotation provided the nose with the torque to lift the nose. The aircraft with the tail at the rear took off, and it was necessary to pry the aircraft up. The torque is very large, and this front canard layout directly lifts the nose of the aircraft, the effects of the two are of course not the same.

Bill was also very satisfied with the control just now, the take-off process was smooth and smooth, this is a real fighter!

Since other systems have been verified on the prototype, it is not like the first prototype does not retract the landing gear when it takes off, and it just circles the airport and returns. After takeoff, it is time to verify the performance of this fighter. Mobility now!

Bill stowed the landing gear, turned on the afterburner, and then pulled the nose up.

Immediately, the plane pointed directly at the sky and climbed rapidly.

This is also a very important indicator, the climb rate, the aircraft has a lot of energy at high altitude, but the fierce air combat will quickly consume this energy, so the shorter the time to climb back to the high altitude, it means that the aircraft In air combat, the more you can gain more advantages.

At this point, the advantage of twin-engine fighters is very obvious.

At 2000 meters in the air, Bill leveled the plane and performed several common maneuvers, such as roll, side slide, and figure-eight flight. The telex system of the Phantom 8 showed excellent agility and quick response. Coupled with the static and unstable design and the front canard, compared with the Mirage 4000, this fighter is the master of the future sky!

Bill pushed the throttle again, reduced thrust, and prepared to recover from the dive.

Suddenly, two rows of red signal lights appeared on the dashboard in front of him.

It turned out to be an engine stop!

"Report, engine shutdown," Bill called over the radio, and at the same time, the rescue operation of the aircraft began.

In the initial test flight, Bill had already made these maneuvers on the prototype, and there was no engine shutdown. Now, an accident suddenly occurred, and the two engines stopped at the same time!

Stopping the engine will cause the power supply to be interrupted, and the backup power supply needs to be left to restart the engine. If the backup power supply is exhausted, it will be powerless at that time.

Therefore, Bill followed the instructions in the radio and began to switch the operation to the standby hydraulic mode. However, this could not last long, because the hydraulic mode also required higher oil pressure. After he operated a few times, the oil pressure It will be lowered, the response of the aircraft will be insensitive, and if it is operated again, it will be completely unable to move.

This point is not as direct as the original operation system that uses cable transmission.

Bill switched to hydraulic mode. Immediately, the control lever was not as easy as before. He barely leveled the plane and aimed it in the direction of the airport.

Next, an order came from the control tower for him to face the airport and drive in the air.

Bill calmly made the motion of driving in the air, flipped a few buttons, and then pressed a switch.

There was a huge roar, and the rear engine started up again.

I don't know how many times this is the first time to rule out a dangerous situation. As a test pilot, you will always be accompanied by death.

Bill didn't feel it just now, but now he realized that his entire back was soaked, so he switched back to the telex operation mode, and he started to return to the airport.

Damn engine!

The crowd waiting at the airport had already received the news, and they were all looking forward to it at the airport.

Finally, Marcel was relieved when he saw the plane again.

Although accidents are likely to happen during the test flight, that is not what any engineer wants to see. Dropping the plane will delay the progress at least, and may lead to the abort of the entire project at worst.

The plane slid back to the tarmac and was towed back to the hangar.

Bill got off the plane, and the engineers had begun to test the aircraft with various data, preparing to find out what the problem was.

"Bill, tell me about the situation in the sky." Marcel asked.

"It was normal at the beginning, and the aircraft operated quickly. After installing the front movable canard, the flight quality has been greatly improved compared to the prototype, but our engine stopped in the air." Bill said.

"What maneuvers were you doing when the engine stopped?" Marcel asked.

"At that time, I was diving, and I had an accident when I was about to recover. Fortunately, I was high enough, otherwise, I could only have parachuted." Bill said.
