Chapter 793 Do it with confidence

"These four helicopters are used for daily flight training." Head Wei pointed to the two helicopters in front of him and introduced to Chen Haiyang: "It is mainly used for formation flying and for practicing some technical and tactical actions, so that Pilots keep the feeling of flying."

Chen Haiyang nodded again and again, then pointed curiously at a few helicopters beside him, and curiously asked Head Wei: "Head Wei, I'm a little curious, why these helicopters are not equipped with weapons, but are those How many helicopters are equipped with weapons?"

Following the direction of Chen Haiyang's finger, you can see several helicopters equipped with different weapons. Two thick rocket launchers are installed on both sides of the fuselage, and a photoelectric turret is also installed at the nose of the helicopter. Compared with the helicopters with weapons installed, these four Helicopters without weapon systems looked somewhat strange—these training helicopters with weapons aroused Chen Haiyang's curiosity.

"Tell me about those helicopters," Captain Wei smiled when he saw the helicopters equipped with weapons that Chen Haiyang pointed at. He said with a smile, "These helicopters are good things."

"Oh?"

Chen Haiyang was intrigued by what Captain Wei said: How come these helicopters are good things?

"You also know that the cost of using real military helicopters is very high." Seeing Chen Haiyang nodding, head Wei went on to say: "After receiving these training helicopters from Huateng Industrial Group for a period of time, our soldiers It was suggested that some of the weapons on our helicopter could be transplanted to this training helicopter for basic shooting training?

After discussion, we all feel that this idea is very constructive and valuable. This trainer helicopter can only carry out introductory flight training for helicopter pilot students and basic flight training for pilots. If this trainer helicopter can be used for Shooting training with machine guns and rockets would be great.

After calculation, we determined that if only one pilot is carried on the plane, and only half of the fuel is loaded, our training helicopter can carry almost all helicopter airborne weapon systems of our army. The only problem is that these weapons The systems cannot be carried at the same time, only one of them can be carried. As you can see, they can either be used for aircraft guns, aviation rockets, or anti-tank missiles. "

"That's what happened."

Chen Haiyang suddenly realized.

"But how can it be so simple in actual implementation?" Looking at Chen Haiyang's dazed expression, Head Wei smiled: "For example, the maximum take-off weight of our training helicopter is only more than 600 kilograms, and our 23-3 type The weight of the aviation machine gun itself is 52 kilograms, plus the control device, 120 rounds of shells and some other supporting auxiliary systems, the weight of the whole system is already hundreds of kilograms.

Such a large weight, as well as the huge recoil force during launch, will cause changes in the aircraft's center of gravity and overall aerodynamic shape?Should the structure of the fuselage be strengthened accordingly?If it needs to be strengthened, how can the weight of the reinforcement be reduced as much as possible while ensuring the strength of the fuselage and the shooting requirements?These all need to be calculated accurately. "

Speaking of this, Captain Wei took a look at Zhang Qihang and said with emotion: "Speaking of which, our regiment really needs to thank Mr. Zhang, if Mr. Zhang hadn't sent their experts and engineering technical team to help us calculate the data, It is impossible for us to even think about making a modification plan, customizing a special pylon and installation system, so that the training of machine guns, aviation rockets and anti-tank missiles can be realized on this ultra-light training helicopter."

Hearing this, Chen Haiyang couldn't help but glanced at Zhang Qihang in surprise. He could see that the other party was sincerely thanking Zhang Qihang, but he saw that the training helicopter produced by Huateng Industrial Group was so popular among the cadres and soldiers of the Army Aviation Regiment of the military region. , Seeing that these helicopters performed functions far beyond their original design, this made him feel a little less confident about the next issue to be communicated with the Army Aviation Regiment of the Military Region: This trainer helicopter performed so well, comrades in the Military Region Can you still agree with us to sell this helicopter to the United States?

With this thought in mind, until the end of the visit, Chen Haiyang finally stated the purpose of his trip: "Director Wang, Captain Wei, what happened, Comrade Zhang Qihang and his helicopter obtained our helicopter a few days ago. Do you know about the airworthiness certificate issued by the Civil Aviation Administration of China?"

"Well, we heard about it." Director Wang and Captain Wei looked at each other, and they both nodded to Zhang Qihang in unison: "Mr. Zhang, congratulations to you."

"Thank you too," Zhang Qihang said with a smile, "If it wasn't for the help from our military region, we wouldn't have obtained the airworthiness permit so quickly."

Director Wang was very happy, he waved his hand: "Ha... It's all as it should be, so I don't need to say these kind words."

"But the problem now is that Mr. Zhang plans to send this helicopter to the United States for airworthiness certification." Speaking of this, Chen Haiyang carefully glanced at Director Wang and Head Wei, and said after deliberation: "So I want to know, What is our military region's attitude towards this matter? Will doing so risk leaking military secrets?"

"Ha ha……"

Director Wang and Captain Wei looked at each other, and then smiled at the same time: I said that this Chen Haiyang is going to the Three Treasures Hall for nothing. I have never seen this guy come to our Army Air Corps before. Why did he suddenly come to us? The Army Aviation Group visited, and it turned out that it was for this matter.

The reactions of Director Wang and Head Wei confused Chen Haiyang: Why do these two people laugh so happily?
"This is no problem, absolutely no problem!" Facing Chen Haiyang who was full of doubts, Director Wang explained to him with a smile: "Director Chen, first of all, on behalf of the Army Aviation Regiment of our military region, I would like to thank you for your attention to this matter. Secondly, you Don’t worry, if you should go to the United States to obtain airworthiness certification, you should go to the United States to obtain airworthiness certification. There is absolutely no issue of leaking military secrets. If your helicopter can open up the situation in the United States, we will only be happy for you.”

Chen Haiyang breathed a sigh of relief when he heard the words, but he was also a little puzzled after he breathed a sigh of relief: "You really won't leak the secret?"

"How...how should I put it?" Captain Wei thought for a while and said, "I'll give you an analogy and you'll understand: the coach helicopter produced by Mr. Zhang and his group is just like the one we used when we were learning the driver's license in the driving school. The trainer car, our trainees just learned how to drive in this 'trainer car'.

But driving a real military helicopter, such as our Zhi-9 and Mi-17, is equivalent to driving a racing car. The various weapons and equipment equipped on the 'racing car' are the things that need to be kept secret. If it is just a trainer plane, it is nothing Leaking secrets does not leak secrets, after all, it is impossible for Americans to measure our combat effectiveness by the level of students.Right? "

Chen Haiyang actually understood this truth, but he was really relieved when he heard this sentence from the leader of the army. He nodded repeatedly: "I understand, with the words of you two, I'm relieved."

........................

Chen Haiyang, who had completely let go of the worries in his heart, turned all his thoughts to the matter of "Huateng Industrial Group is going to the United States to do airworthiness certification for its helicopters and earn money from the Americans". , On the way back, he couldn't wait to ask Zhang Qihang: "Xiao Zhang, how much do you know about the process of taking the aircraft to the United States for airworthiness certification? Do you know how this process should go?"

"Leader, I'm about to report to you about this matter."

"Well, you said."

"It's like this," Zhang Qihang said, "Because the maximum take-off weight of our helicopter is only over 600 kilograms, we are going to apply for the certification of a light sport helicopter..."

"Wait a minute," Chen Haiyang interrupted Zhang Qihang, and asked seriously, "What do you mean by this light sport helicopter?"

As the head of the Provincial State Z Committee, although his knowledge of aircraft is limited to some common sense things, after knowing that this project is so profitable, he is full of interest in this knowledge. A concept that has never been heard before, and a strong thirst for knowledge suddenly surged up.

"Uh... light sport helicopters are a classification of aircraft." Speaking of this, Zhang Qihang looked at Chen Haiyang's deep curiosity, thought for a while, and asked tentatively: "How about I introduce it to you in detail?" ?”

"Okay," Chen Haiyang nodded, and sat upright seriously: "Tell me how these things are classified."

Zhang Qihang responded, and after deliberating for a while, he said: "According to international practice, aircraft are roughly divided into ultra-light aircraft, light sports aircraft, and normal aircraft.

The first is an ultra-light aircraft. The core indicator of an ultra-light aircraft is weight. Specific to the type of aircraft, if it is an unpowered aircraft, its own empty weight must be less than 71 kg; if it is a powered aircraft, its own weight must be less than 116 kg..."

An aircraft with a deadweight of less than 116 can only be regarded as an ultra-light aircraft, and this division method is still very accurate.While Chen Haiyang nodded secretly in his heart, he couldn't help interrupting Zhang Qihang's words and asked, "There are still unpowered aircraft?"

"Yes," Zhang Qihang said, "such as paragliders and delta wings."

"Oh, I understand when you say paragliding and delta wing."

Chen Haiyang nodded and signaled Zhang Qihang to continue.
