"This plane ......"

After staring at the screen for a long time, Sun Huizhong finally spoke again:

"I think the potential of this aircraft may not only be limited to being a trainer aircraft, but may also be used part-time as a light attack aircraft."

His mind was now full of trying to figure out how to make an airplane that was in greater demand.

It is also possible to sell to foreign customers.

At this time, the status of enterprises that can earn foreign exchange for the country can rise like a rocket.

In addition to the two-seater fighter can be used for teaching, the extra pilot can also be used to do some operations that have nothing to do with operating the aircraft, such as searching for targets and controlling precision-guided weapons.

While these features can also be concentrated on single-seater aircraft, there are risks associated with allowing pilots to focus on two things.

Therefore, it seems to be a pretty good choice to let the advanced trainer aircraft, which has good flight performance, take on some ground attack missions part-time.

After all, the cost is low.

"But after all, it is the same volume as Jianjiao 7, and I am afraid that the bomb load and range will not be too optimistic......"

Another raised his own concerns.

"It's better than the strong 5 you have now, right?"

Someone immediately retorted:

"And it can also be equipped with radar and precision-guided weapons."

"What precision-guided weapons do we have now?"

"Uh...... There will always be ......"

“……”

Soon there was a lot of discussion around them.

"Is this...... In fact, it is completely possible to do some fine-tuning on the same platform. ”

As soon as Chang Haonan, who was in the middle, spoke, the others quickly quieted down, waiting for his following:

"For example, try to further increase the wingspan and reduce the sweep angle, so that the area of the outer wing section is increased, which can accommodate a group of additional fuel tanks to improve the range, and then install different on-board equipment, you can develop two sub-models for customers with different needs."

"Like our country, there may no longer be a need for light attack aircraft in the future, so you can buy an advanced trainer type, that is, the rear cabin only retains higher authority driving functions, and there is no need to install radars and mount large-sized ammunition."

"Won't there be a follow-up model for the Strong 5?"

Sun Huizhong was a little surprised by this judgment:

"I have a classmate who works in Hongdu, and they are thinking about a new attack aircraft project."

Chang Haonan nodded:

"Times are no longer the same, for a large country like ours, the future will be the world of multi-role fighters, at most a small number of fighter-bombers."

The positioning of the strong 5 is completely different from the Su-25 and A10, which are more common at present, it has no armor, and the low-speed performance is also very poor.

It's just that due to the limitations of technical conditions, the ammunition with it has never been available, and the Hurricane-1 is actually just a nuclear trigger, so with the attitude of giving full play to the residual heat, coupled with the army's long-term lack of dedicated armed helicopters, this model of top cylinder has taken on the task of close support.

At this stage, which is about to enter the new century, there is no place left for light attack aircraft in the air force sequence.

"So, what about the other than the advanced coach type?"

Someone still pulled the topic back.

"Although there is no need in our country, some foreign users, especially those in Asian, African and Latin American third world countries, are basically only fighting rebels or terrorist ...... Guerrillas, so there will still be a place for this kind of aircraft, you can buy a combat trainer type, install more advanced airborne equipment in the rear cabin, such as a multi-function display, and leave two more spacious hanging points for hanging some air-to-surface missiles and the like. ”

"Shhh...... Can this be? ”

The rest of the crowd showed expressions of surprise or sudden realization.

This idea would not have been very popular in the mid-90s, but in the 21st century, with the rapid rise in the cost of fighter jets, many small countries began to consider abandoning the establishment of an air force capable of air combat (it is better to abandon the treatment altogether anyway), and instead use trainer/attack aircraft and Chada drones as the main models.

"Of course, in the next period of time, I will work with you to improve this plan, and then optimize the design of several key parts, and when you master the design method, you can also make subsequent adjustments to the aircraft according to the actual needs and future test flights."

Chang Haonan turned his head and looked at the few good seedlings sent by 648 in front of him and said.

After more than half a year of training, he has gradually become accustomed to the computer foundation of people in this era, and there will no longer be the same oolong as when he taught Yao Mengna.

Before being reborn, all graduate students must have been quite proficient in numerical simulation, and more or less know one or two basic programming languages.

But in 1997, most designers had some understanding of several common modeling and fluid calculation software, and it was rare to have read books and operated them themselves.

This situation will probably take another two or three years, and it will be fundamentally alleviated when the same batch of students as Chang Haonan graduate with a master's or doctoral degree.

"We'll all listen to you!"

Everyone, including Sun Huizhong, instantly showed excited expressions.

Everyone is a person who can enter the aircraft design and research institute, and naturally knows the difference between a satiety meal and a full meal.

This kind of opportunity for a bigwig to teach you how to design an airplane is not available to everyone.

Not to mention learning all the abilities of the other party, even if you learn three or four percent, it is enough for 648 to toss some new tricks.

"Well, I have just explained the overall design of the aircraft, so let me first systematically introduce the theoretical basis and basic steps of digital design......

In the following two hours, Chang Haonan gave a lesson roughly equivalent to an introduction to the engineers of the 648 Institute in an empty conference room with a blackboard next to him.

Fortunately, these college students who graduated in the 90s and even at the end of the 80s have a much more solid theoretical foundation than later generations, so it is not difficult to work hard in this regard, but they are similar to Lin Shikuan and them at the 601 Institute, and they need to change their thinking.

"Considering that everyone's experience is not enough, it is still necessary to step by step in terms of design difficulty, in any case, first get the specific design plan out as soon as possible, so that the superior units and users will have confidence."

"So we can use a more traditional bulkhead air intake in the initial design, and the design of the side wing can also be a little more conservative, and wait until the project is actually applied, or even after the first prototype makes its first flight, and then slowly use some more radical technology."

After saying this, he put down the chalk with a dry mouth, picked up the cup and poured a large mouthful of water.

In fact, it's quite normal to dedicate an aircraft to validate a technology.

For example, on the U.S. side, it is on a modified F16block30 for technical verification of the DSI air intake.

The USSR also verified the appropriate amount of axial symmetry on a modified Su-27UB

It's just that Chang Haonan wants to be more efficient, and by the way, he will get the coach 9/FTC2000 out in the process.

"Are you so sure the Air Force will approve of our model scheme?"

Obviously, some people are not very confident, after all, the 648 Institute has really had no successful experience in this area in the past.

"Of course, that's what I'm going to talk about next."

Chang Haonan flipped the blackboard that had been written to the other side:

"In the final version of the design, I was going to use a supersonic air inlet without a surface layer, which is the DSI air intake."

"On the one hand, this can reduce the weight of the aircraft by about 130-150 kilograms, on the other hand, and more importantly, it is also to borrow this overall low-risk project for verification, if the technology is mature, then it can be used in Project 10, and even more in the future of the fourth generation fighter."

"With this second reason, and the fact that the Air Force does need a new type of advanced trainer aircraft, I think it should be nine out of ten to formalize this model."
