The military-industrial scientific research system of the academic master.

Compared to the laymen who were just watching the excitement on the ground, Wu Guohui in the cabin was even more overjoyed at this moment.

Because he can even feel his hand gripping the control stick, the aircraft can still adjust its flight attitude according to the subtle movements of his hand.

In other words, at this large elevation angle of about 110°, the JJ-9 is still controllable!

This is much more meaningful than simply flying a Cobra maneuver.

Whether it is Su-27 or F18, although many types of aircraft have made the same action in the past, most of them were essentially in a semi-out of control state during the process of raising their heads and finally returning to level flight.

That is to say, although the aircraft can remain stable and avoid flying randomly due to its aerodynamic design, it cannot be controlled within a specific angle of attack range.

It's just that different models have different stages of losing control.

If you want to restore complete control, you can only wait until level flight is restored.

Of course, there are also high-ranking players such as No. 711 Verifier or HARV Verifier, but they all use vector propulsion technology to cheat.

The JJ-9 does not have these tricks and tricks, and relies entirely on aerodynamic design to maintain maneuverability at large angles of attack.

“The maneuverability is very good.”

Wu Guohui had already given this aircraft a high basic score in his mind.

After a little experience, he quickly leveled the plane.

The reason why over-stall maneuvers have little practical significance is that on the one hand it is difficult to control during the maneuver, and on the other hand it will cause the aircraft to lose a lot of speed.

Even after some improvements, the JJ-9 is not an aircraft known for its energy. It needs a period of acceleration in level flight to prepare for the next move.

Taking advantage of this gap, Lin Haijun started to improve his own products.

"Although our aircraft is a training aircraft, its maneuverability has definitely reached the level of a fighter jet. Several of you must have seen this before."

"For student pilots, trainer aircraft with stronger controllability and maneuverability will also help them adapt to real combat aircraft faster and reduce the possibility of accidents during flight training. Even if a stall or spin occurs, as long as When the pilot releases the control stick and pedals, the flight control system will automatically recover and resume level flight..."

The automatic leveling function was actually not that rare in the late 90s, but for some potential customers who had never used high-end products, it was still worth writing about.

"Moreover, the JJ-9 itself also has the ability to use weapons. The combat training type is even equipped with a fire control radar, which can launch medium-range missiles for beyond-visual-range combat."

As he spoke, he held up a wooden airplane model to demonstrate to several customers.

The other party was actually from Sudan, and their original intention was just to purchase a few advanced trainer aircraft that could train pilot students.

苏丹空军装备着大约20架强5IIA、15架苏25和4架苏24M，并且正在采购一批经过升级、可以发射R77主动弹的米格29S，在非洲大区算是一支勉强够看的空中力量。

In the past, their air force pilots were mainly trained by the Egyptian Air Force.

Although there are territorial disputes between the two countries, the reason for the dispute is that they both believe that the two territories should belong to each other, so they are in peace with each other.

Until oil was discovered beneath one of the fields...

In short, the Sudanese Air Force feels that it must establish an independent flight school.

Having said that, they were obviously shocked by the performance of the JJ-9 just now.

Marat, the Sudanese Air Force Chief of Staff who led the team, put down his telescope and suddenly felt that for such a limited air force under his command, there would be nothing wrong with having more aircraft that could be used for combat.

Lin Haijun quickly saw the interest in this model from the other party's eyes.

Considering that the Sudanese Air Force has little need for air combat, he quickly turned the topic to the multi-purpose capabilities of the aircraft.

"Our JJ-9 can maintain a minimum level flight speed of 195km/h. Compared with the Qiang-5IIA used by your country's air force in the past, it is more suitable for ground attack, and its maximum speed can reach 1.2 times the speed of sound. Compared with the Su-25, it can Reach the battlefield faster..."

"The advanced training type has a total of 7 weapon hardpoints, while the combat training type has 9, and can mount up to a total of 3 tons of weapons and equipment."

"We have reserved a light hanging point with a data interface on the left front of the belly of the aircraft, which can be used to mount a data transmission pod or a laser targeting pod to use TV-guided or laser-guided precision-guided weapons. This is also an old model. What attack aircraft don’t have…”

The best way to bring goods is actually to push them. Therefore, Lin Haijun spoke eloquently and easily described his own products as the most suitable equipment for the air forces of third world countries.

In fact, he didn't lie. It's just that at the moment, China's aviation industry cannot provide supporting equipment.

But it doesn’t matter, the hardware interface has been reserved, and the rest can wait for OTA.

Sure enough, Chief of Staff Marat didn't pay much attention to precision-guided weapons.

Sudan's first large-scale oil field was built by China Oil and Gas Company. It has not yet been put into production, and it is not yet wealthy enough to use precision-guided weapons on a large scale.

Besides, the main opponents they face are some separatist armed forces and terrorists in the Sahel region. It is enough to be able to fire a rocket.

“What’s the range of this plane?”

What Marat is concerned about is that the battery life must be long enough. Otherwise, others will hide for a while when they see the plane coming, and you will have to return quickly if you can't find the target, which would be boring.

Since ordinary trainers do not have this requirement, they generally do not set too long a blank time.

Fortunately, the JJ-9 was born out of a serious fighter jet and had an engine with lower fuel consumption.

"With three auxiliary fuel tanks, the maximum range is 2600km, far exceeding most similar models."

Lin Haijun continued to diss his friend businessmen mercilessly.

Having said this, he suddenly had a flash of inspiration and added:

"If your country particularly needs to carry out some long-term air patrol missions, then... our company is actually developing a drone, similar to the one used by the US military. Mr. Marat can wait until next year to take a look..."

While the two were talking, Prototype 01, which had circled around in a circle, flew back again.

Only this time, they were flying in formation with the accompanying J-7.

Marat raised his telescope again.

But this time, from a visual perspective, there doesn’t seem to be anything special.

Just when he was a little confused, a conversation between the tower and the aircraft came from the radio next to him.

Lin Haijun directly took on the role of translator:

"This is to test the control accuracy of our aircraft. The tower requires the relative position of the J-9 behind it to be 5 centimeters forward."

"Seize the young master?"

If the telescope hadn't been hanging around his neck, Marat might have dropped it with a shaking hand.

"5 centimeters."

Lin Haijun repeated it in English, and then admired the dumbfounded expression of the old Arab man in front of him——

For the JJ-9Y used exclusively by the performance team, Sun Huizhong creatively installed a radio rangefinder customized from Electronic 14 on the nose of the aircraft at the position originally reserved for radar, which can directly display the 120° range of the front hemisphere on the aircraft's HUD. The relative direction and distance of the inner target.

Compared with radar, this gadget has a range of no more than 100 meters, but it can track up to five targets at the same time with higher accuracy.

It is a function completely customized for formation flight performances.

Combined with the turbojet 14B engine with fast and accurate throttle response, the aircraft can completely fly in formation with centimeter-level accuracy.

Of course, since there is no FADEC, the engine is still controlled independently by the throttle lever, so this gameplay requires very high manual skills from the pilot.

Judging from the training level of the Sudanese Air Force, it is difficult for any pilot to achieve this level.

and. The device itself is not small, so it cannot be installed on the combat trainer type.

In fact, even the Advanced Coach type is not really needed.

After all, except for the performance team, there are no scenes that require pilots to make such outrageous actions as "nearly 5 centimeters".

Even mid-air refueling doesn't have to be so precise.

But the psychological impact this conversation had on Marat was real.

He was hesitant just now and blurted out almost without thinking:

"So, what's the price? How much does your plane cost?"

Marat calculated the budget that the president had approved for him before leaving, and asked a little uncertainly.

According to his experience, if something looks good everywhere, its only drawback may be that it is expensive.

Fortunately, China accepts various flexible trading methods.

"In addition, this is just the first prototype after all. When can the mass-produced model be officially delivered?"

When he heard these two questions, Lin Haijun knew that his Gui Aviation Industry could be saved.

Even if they cannot receive cash in foreign exchange, in the barter transaction model, other domestic units will give them money in the form of fund transfers.

For Guihang, which is struggling to survive, as long as it is money, it is good.

"Including necessary spare parts and training, the unit price is US$850 million for the advanced trainer model and US$1000 million for the combat trainer model."

"As for delivery, almost all subsystems on this aircraft are relatively mature models. There are relatively few test flight subjects required before mass production. According to conservative estimates... delivery can begin within two years."

In fact, based on the current timetable, the finalization cycle of JJ9 is even shorter.

It’s just that you have to leave some room for words.

Guizhou Airlines really cannot afford the liquidated damages for delayed delivery...

"if it is like this……"

The price Lin Haijun said made Marat's eyes light up:

"I think we can discuss more specific details of the transaction."
