As soon as the motor sounds, there are ten thousand taels of gold.

For fighters, a take-off and landing will cost thousands of dollars, pilots, it is all burned money, and test pilots are even more expensive.

Now, the Chinese delegation came to Egypt mainly to inspect the two planes and then bring them back.

However, Colonel Mustafa is very generous, and now the relationship between Egypt and China is quite good, otherwise he would not have exchanged his own fighters to China, anyway, he has come here, so what about a test flight?

The MiG-23 is not good, if it is not trained, it is very dangerous to fly directly with a variable sweep wing, but the MiG-21 is different, no matter how it changes, it is still a MiG-21.

Qin Feng's face showed an excited expression: "Okay, if you have the opportunity to go to my country in the future, I will also ask you to fly." ”

Qin Feng said very easily, please take a plane, that is even more hospitable than the Saudis.

However, Qin Feng doesn't have to worry about breaking his promise, if the other party really goes to China, relying on the friendship between the two sides today, he will report and ask the other party to fly, then it will definitely be no problem.

Everyone thinks that this taxi is too shabby, so go and take the tourist bus in the back, and Qin Feng is here, and he has made friends with the Egyptian colonel, and the harvest is really good.

At this time, the two cars had already driven out of Cairo City, and outside, there was already a scene.

The desert, the endless desert, undulating, is full of sand dunes, and it is already a desolate scene.

Although it was not the first time to see the desert, Qin Feng saw such a hot desert for the first time, and he didn't dare to open the window, the heat wave outside hit people, and the air conditioner no longer worked because of the high speed of the car, and the temperature inside the car continued to rise.

This dilapidated taxi, in the hands of the driver, can actually go wild, and there are no other vehicles on the road in the early morning, and soon, the characteristic roar of the fighter plane is heard.

Beni Suef Air Base.

At this time, the routine training of the Egyptian Air Force has begun, and from Qin Feng's point of view, a beautifully shaped fighter is taking off.

Green and yellow desert camouflage paint, this aircraft is different from the previous aircraft, the nose is pointed, there are rectangular air intakes on both sides, from this angle, the wings on both sides, are in a state of full expansion, the wide wing box, is so clear.

MiG-23, a fighter with a variable sweep wing!

Although he had seen photos of this aircraft in magazines before, that small black and white photo was not easy to resonate with people, and now, watching this huge fighter plane take off, Qin Feng was instantly attracted.

Variable swept wing design, the most popular aerodynamic layout scheme for fighters in this era!

Straight wings are good for low-speed flight, but when the flight speed of the aircraft is close to the speed of sound, it will produce shock waves that increase the drag dramatically; The swept wing can not only delay the generation of shock waves, but also the shock wave intensity generated at supersonic speed is much smaller than that of straight wings, but the low-speed performance of large swept wing aircraft is very poor, and it takes a long glide distance to take off and land, and the economy and safety are not good.

Variable swept wing technology solves the problem of compatibility between high and low speeds.

"In the armament of our Air Force, the MiG-23 is already the most advanced aircraft." Colonel Mustafa said: "Now, let's go and see the MiG-23 first."

The two cars drove to the hangar in one go.

Although the Soviet fighter planes were designed with the open air storage in mind, they were relatively strong, but the wind and sand in the Middle East and North Africa were too large, which was quite unfavorable to the maintenance of the fighters.

Moreover, it is necessary to take into account the situation of the war, after all, until now, if nothing else, there have been four wars in the Middle East, and each time the war begins, the first thing to destroy is the enemy's air base, to destroy their fighters.

So, the Egyptian air base has a sturdy reinforced concrete hangar.

Although the distance was 200 kilometers, it took two hours to get there, and even so, when they came down, they still felt a little tired.

In addition to the fatigue of the journey, the scorching heat also made them a little unbearable, but these were nothing, and when they saw the fighters in the hangar from the car window, everyone was immediately in high spirits.

MiG-23! The most advanced variable-swept wing fighter of the USSR!

Of course, it is definitely not the most advanced, when it still uses backward manual control, the American Tomcat fighter is already automatically controlled by the on-board computer, and the wing of the MiG-23 has only three positions, while the Tomcat fighter can fly at any angle.

However, in the eyes of Mr. Gu, Song Lao and others, this is already the most advanced.

After all, now the domestic industrial base is weak, there is nothing, and the main thing that China is now drumming up is the J-6, and even the J-7 and J-8 are considered advanced weapons.

The J-8 is a double-engine large version of the J-7, which is still nose intake, and has no all-weather flight capability, so it is a day fighter.

If you can get close to the MiG-23, you can graft the nose of the MiG-23 to the J-8, so that the J-8 can free up the huge space in the nose!

Mr. Gu was the first to jump out of the car and run towards the MiG-23, as if the groom was greeting the bride.

Song Lao also walked down and looked at the MiG-23 quietly, but for some reason, he suddenly thought of his own J-9 project.

The MiG-23 is a variable sweep wing, while the J-9 uses a canard wing layout, which of the two is suitable for the future sky?

"Okay, let's get to work now, let's complete the acceptance of this MiG-23 first." Director Tang said.

Almost everyone is a veteran of the development of domestic military aircraft, and they are mainly responsible for the acceptance of the two aircraft, and after the acceptance is completed, they will pack and take it away, after all, they want an intact fighter.

The workload of the acceptance fighter is very large, and all systems of the aircraft must be checked by power; The engine is tested on the spot to verify the thrust data under cruising, rating, maximum, small afterburner and full afterburner; The main on-board equipment, especially the control system of the variable sweep wing, is subject to functional testing.

In addition to this, there is the collection and collation of technical information, which is very important to Egypt, although it does not have much information.

Then, just roll up your sleeves and plunge into the vigorous work!

Wait, what about Qin Feng? Where did it go?
