Chapter 500 "Mountain Eagle" flying to the world
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 joystick, 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-level players such as No. 711 Verifier or HARV Verifier, but they are all cheating through vector propulsion technology.
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 movement, 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, the maneuverability of the aircraft has definitely reached the level of a fighter jet, which some of you must have seen just now.”
“For flying For students, a 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 the pilot releases the By pressing the joystick and pedals, the flight control system will automatically recover and resume level flight..."
The automatic leveling function was actually not particularly rare in the late 1990s, but for some high-end products that have not been used much, For potential customers, it is still worth writing about.
"Moreover, the J-9 itself also has the ability to use weapons. The combat training type will even be equipped with a fire control radar, which can launch medium-range bombs for beyond-visual-range combat."
He said while taking the Demonstrating to several customers with a wooden airplane model.
The other party is actually from Sudan, and their original intention is to purchase a few advanced trainer aircraft that can train pilot students.
The Sudanese Air Force is equipped with about 20 Qiang 5IIA, 15 Su 25 and 4 Su 24M, and is purchasing a batch of upgraded MiG 29S that can launch R77 active bombs, which is considered a leading force in Africa. The air force is barely enough to see.
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 under one of the pieces of land...
In short, the Sudanese Air Force felt that it had to establish an independent flight school.
Having said that, they were obviously shocked by the performance of the JJ 9 just now.
Marat, the chief of staff of the Sudanese Air Force who led the team, put down his telescope and suddenly felt that for an air force with a limited scale like his own, there would be nothing wrong with having more aircraft that can 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 almost no air combat needs, 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 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, which can be used to mount a data transmission pod or a laser targeting pod, so as to use TV guidance or laser guidance. Precision-guided weapons are something that older attack aircraft do not possess..."
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.
Actually, he didn't lie. It's just that at the moment, China's aviation industry is unable to provide supporting equipment.
But it doesn’t matter, the hardware interface has been reserved, and the rest can wait for OTA.
As expected, Chief of Staff Marat didn't care much about 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 endurance time must be long enough, otherwise others will hide for a while when they see the plane coming, and you will have to find the target if you can't find it. Returning soon would be boring.
General trainer aircraft generally do not set too long a blank time because they do not have this requirement.
Fortunately, the JJ-9 was born out of a serious fighter jet and replaced with an engine with lower fuel consumption. "With three auxiliary fuel tanks, the maximum range is 2,600km, far exceeding most similar models."
Lin Haijun continued to diss his friends and businessmen without mercy.
Speaking of this, he suddenly had a flash of inspiration and added:
"If your country particularly needs to perform some long-term air patrol missions, then... our company is actually developing A kind of 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, the No. 01 prototype that circled around flew again. Come back.
Only this time, they were flying in formation with the accompanying J-7.
Marat raised the telescope in his hand again.
But this time, visually, 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 acted as the translator:
"This is to test the control accuracy of our aircraft. The tower requires that the relative position of the J-9 following behind is 5 centimeters forward."
"Less less?"
If it weren't for the telescope hanging On the neck, Marat might have dropped it with a shake of his hand.
“5 centimeters.”
Lin Haijun repeated it in English, and then admired the dumbfounded expression of the Arab man in front of him——
For the JJ-9Y dedicated to 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, the range of this gadget is only no more than 100 meters, but it is better than that it can track up to five targets at the same time with higher accuracy.
It is 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 coaching 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 does not need to be so precise.
But the psychological impact this conversation had on Marat was real.
Having been hesitant just now, he blurted out almost without thinking:
"So, what about the price? How much does your plane cost?"
Marat made a calculation. He asked a little unsure about the budget the president had approved for him before leaving.
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 only the first prototype after all. When can the mass production model be officially delivered?"
When hearing these two questions, Lin Haijun knew that he Guiyang's aviation industry can 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 for the advanced trainer model is US$8.5 million and the combat trainer model is US$10 million."
"As for delivery, almost all subsystems on this aircraft are A relatively mature model requires relatively few test flight subjects before mass production. If it is conservatively estimated... it can be delivered within two years."
In fact, based on the current schedule, the JJ-9 will be ready for production. The finalization cycle 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 that's the case..."
The price Lin Haijun said made Marat's eyes light up:
"I think we can discuss more specific transaction details."< br>
