The Y-30 transport aircraft has entered the stage of comprehensive design and research and development.

Another development task from the military was notified by Zhang Haiping on the form of a telephone, asking Tianfeng Technology Company to carry out the design and development of another transport aircraft.

The military has requirements for this transport aircraft, not only as for the Y-30 transport aircraft, but also for landing on a field runway, with good low-altitude and low-speed performance, long life, high reliability, etc.

At the same time, Zhang Haiping also said that this transport aircraft will be an important auxiliary force in the military's strategic air transport, and it is also a subsequent research and development platform for various aircraft.

In these cases, it is necessary to consider that based on this transport aircraft, early warning aircraft, aerial refueling aircraft, electronic jammers, and even various military and civilian cargo aircraft can be derived.

The military has not issued formal documents and information, and these requirements were also verbally stated by Zhang Haiping on the phone, and are for reference only for Tianfeng Technology Company.

But the development of this transport aircraft is a foregone conclusion.

The two of them communicated and communicated on related matters on the phone.

Zhang Haiping said: "Mr. Li, then this matter is settled. If nothing unexpected happens, this transport aircraft is code-named Yun25, and it may be the military transport aircraft with the largest number of equipment in the future."

Yun25 transporter

There is an official code before the development has begun, which shows how much the military attaches importance to this transport aircraft. Li Tianfeng thought to himself, the Y-25 transport aircraft is good

Li Tianfeng said happily: "Okay, Minister Zhang, that's it."

In fact, without Zhang Haiping's suggestion, in Li Tianfeng's mind, the Yun25 is a very good platform. It is of moderate size and can just lead to many models.

The Yun25 can not only take off and land on the runway of the frontline airport, transport or airdrop military personnel and equipment to the battlefield. It can also be used to retreat wounded people when returning.

Based on the 25, the modified 25 transport function can be used to perform various tasks. It is used for electronic monitoring of air command and control and communication, etc.

In addition, there are search and rescue and recovery type aerial refueling type special mission type meteorological detection type maritime patrol type and air early warning type, and there are also a large number of civilian types.

In other words, the Y-30 transport aircraft is purely military, while the Y-25 transport aircraft will have a wide range of uses in the future. It can not only be used for both military and civilians, but also for civilian freight transportation, but also extended design and research and development, and derived many models.

Based on the fact that the Y-25 is such a transport aircraft, Li Tianfeng had a relatively good idea in his mind, no longer limited to military use, but hoped to be widely exported and widely used in civilian use.

So, Li Tianfeng said: "Minister Zhang, we will start the design and development of the Yun-25 transport aircraft immediately and come up with the design technical outline within half a month. However, I have a little request and I hope the military can focus on it."

He took out the design technical outline of the Yun-25 transport aircraft within half a month. Li Tianfeng was sure because the Yun-25 transport aircraft can basically be "shrink-scaling" on the foundation length of the Yun-30 transport aircraft, and many things can be learned from.

Li Tianfeng had a little request. Zhang Haiping was a little surprised. Then, Zhang Haiping smiled and said, "Mr. Li, it's okay to just say anything you have."

Both of them are old friends, so there is no need to keep anything in the way. It can be said directly. So Li Tianfeng did not beat around the bush and directly made his own request.

Li Tianfeng said: "Minister Zhang. The Yun-25 transport aircraft is both military and civilian. Such a transport aircraft cannot have an export ban. I hope the military will consider this requirement."

The Y-30 transport aircraft. Once successfully developed, it will be the military's strategic air transport force. This transport aircraft is too powerful. Li Tianfeng knows that it will definitely not be exported. It is used exclusively by the military and is within the scope of strict confidentiality.

But if you are in the 25, there is a little difference. The 25 transport aircraft is slightly smaller, with a load capacity of about 100 tons. It is not only very adaptable, but also can be used as a civilian cargo aircraft. I believe many countries want such a transport aircraft.

In addition, the export of transport aircraft is more relaxed than that of fighter aircraft. If such a transport aircraft can enter the international market and be widely exported, it is naturally what Li Tianfeng hopes.

Zhang Haiping immediately understood what Li Tianfeng meant. Zhang Haiping laughed and said, "Mr. Li, I can't make the decision on this matter. I will report it to the leaders. However, personally, I think there should be a lot of hope for this matter."

The military already has a Y-30 transport aircraft, so there will be no strict restrictions on the export of Y-25 transport aircraft. Zhang Haiping also knows this, so Zhang Haiping said that he has great hope.

The two agreed on everything on the phone. After the call with Zhang Haiping, Li Tianfeng even remembered and the design of the Yun-25 transport aircraft appeared in his mind.

………

After receiving the call from Li Tianfeng, Lei Yong rushed over from the south base of the city and entered Li Tianfeng's office. Lei Yong said: "Boss, please look for me."

Li Tianfeng signaled Lei Yong to sit down by himself, and then Li Tianfeng said: "Mr. Lei, how is the design and development of the Yun-30 transport aircraft?"

Lei Yong said: "It has been fully rolled out and entered the stage of full-scale design and research and development. In addition, your design sketches have been sent to relevant design rooms."

Li Tianfeng pointed at it. In order to ensure that the Y-30 transport aircraft is successful as soon as possible and as soon as possible, Li Tianfeng personally drew a large number of design sketches.

In terms of structural strength design alone, Li Tianfeng drew more than twenty design sketches of large and small size. Many of these sketches even marked the main design size and design requirements.

A few months ago, Li Tianfeng considered the design and development of the Y-30 transport aircraft. In Li Tianfeng's mind, the design plan was mature and the design sketches had already begun to be drawn. Before the formal design outline came out, Li Tianfeng drew a large number of design sketches.

These design sketches are not just structural strength design sketches, but involve all aspects, such as pneumatic design, cargo hold design, landing gear design, compartment design, power system design, avionic system design and other aspects.

These design sketches will help everyone avoid many detours, which is equivalent to pointing out the direction of the design. In addition, Li Tianfeng's guidance in the design and development process, the design and development of the Y-30 transport aircraft will not have any major design difficulties and difficult design problems.

At present, the design and development of the Y-30 fighter jet is fully launched, and it is in full swing. Li Tianfeng nodded with satisfaction.

Li Tianfeng said: "Mr. Lei, this time we came to you, mainly because we received another military R&D task."

"Oh." Lei Yong was very excited and immediately said with great interest: "Boss, the military wants us to develop another aircraft?"

Li Tianfeng said: "Yes, it's still a transporter, a transporter with a load capacity of about 100 tons. The code name of this transporter is Yun25..."

Li Tianfeng said it in detail, including the issues and matters that need to be paid attention to in the design and development of Y25, some special requirements, some major design parameters, etc.

According to Li Tianfeng's idea, the maximum load capacity of the Yun-25 transport aircraft is about 100 tons, which is slightly smaller than the American C5 "Galaxy" transport aircraft.

However, the overall performance and design technical content of the Y25 will be above the C5 Galaxy transport aircraft. After all, the American C5 Galaxy transport aircraft was developed in the 1960s, and now it is in the 21st century.

The 25 transport aircraft uses two turbofan 30 transport aircraft, with a range of more than 8,000 kilometers. If refueling is carried out in the air, the range will be further increased.

A range of 8,000 kilometers is enough to conduct intercontinental flights. You should know that the maximum range of the C5 transport aircraft is only 56,000 kilometers.

The take-off weight shall not exceed 280 tons. The load capacity is about 100 tons. If the fuel is filled, the take-off weight shall not exceed 280 tons. This requires the Y-25 transport aircraft to be both strong and light, and will use a large number of non-metallic materials, such as "Hercules" materials, etc.

Li Tianfeng explained the design requirements and main parameters of the Yun-25 transport aircraft in detail, and then said: "Mr. Lei, I took out the design technical outline in half a month. Are there any problems?"

Lei Yong said confidently: "Boss, there is no problem."

Seeing Lei Yong so confident, Li Tianfeng smiled happily.

………

Capital, military building.

Zhang Haiping was reporting to Mr. Wei, and Zhang Haiping said: "Chief, Tianfeng Technology Company is very sure of the design and development of the Y-25 transport aircraft, but Mr. Li has a small requirement."

Mr. Wei said: "What are his requirements? Let's listen."

Zhang Haiping said Li Tianfeng's request. After hearing this, President Wei smiled and said with a smile: "This Li Tianfeng, Yun25 has not been developed yet, so he has taken the export matter."

After thinking about it, Mr. Wei said: "We already have a super large transport aircraft of 30 and 25. As he wishes, exports are allowed. We will no longer restrict them or issue export bans."

"However, we also have a small requirement. The comprehensive performance and technical content of the export-type Y25 transport aircraft must be lower than the Y25 transport aircraft we use."

The military-specific model is naturally an upgraded and enhanced version. As for the export model, it must be a simple version. That's what Mr. Wei means.

However, if the Y-25 transport aircraft is excellent enough, even the simple version will be very good and very outstanding, and will definitely be much better than the current transport aircraft.

Zhang Haiping naturally understood what Mr. Wei meant. Zhang Haiping immediately said: "Chief, I think there is no problem. The Yun-25 transport aircraft provided to us by Tianfeng Technology Company is definitely the best and best. In addition, I will inform Mr. Li of your request."

In fact, without Zhang Haiping's advice, Li Tianfeng also had such awareness and plans. The military-specific Y-25 transport aircraft is definitely the best.

The export type is the Yun25a. Although the military-specific model is basically the same as the export Yun25a, it will definitely be much better in software, such as avionics systems, control systems, radar systems, etc. Compared with the export type, it will be much more advanced.

Tianfeng Technology Company is very confident that it will be successfully developed for the Yun-25 transport aircraft. Mr. Wei was very happy, and even a rare hint of joy appeared on his face.
