"When the engine is turned on afterburner, its fuel consumption is at least twice as high as under normal conditions, and the range of the corresponding aircraft will also be reduced, with non-afterburner fuel consumption of 0.75-0.8Kg/h Kg thrust and afterburner fuel consumption of 1.8Kg/h Kg thrust.

At the same time, the afterburner will shorten the engine life because it dramatically increases the temperature and pressure of the afterburner section of the engine's internal channel, as well as the speed of the core turbine.

According to the data of this alloy material, it is not possible to meet the above thrust conditions, of course, I am talking about the data of the third generation of combat effectiveness, the transport aircraft may be smaller, I will reduce it by ten percent, even so, there is still a certain gap in the parameters of this alloy material, my suggestion is to add a little manganese in this material, the specific quantity is not good, this needs to be tested ..........

By the way, the maximum afterburner time allowed for the Russian jet engine is generally not more than two minutes, and the maximum afterburner time for the jet engine in the United States and Western countries is generally not more than five minutes.

In addition, it should be noted that the color of the engine flame is related to the adequacy of fuel combustion, the full combustion is blue, the insufficient is yellow, and the blue flame and yellow flame can also be seen at the same time.

The flame of the Russian fighter is blue when it is powered, and the United States is yellow, which shows that the Russian engine mainly relies on increasing fuel utilization, and the United States relies on increasing fuel combustion. ”

Well, few of the people present could understand Liu Lang's words, but fortunately, what he said was written in the information, which can be said to be written for the National Large Aircraft Engine Program, and it is a material based on Kaminsky's materials that can make the scientific research group more purposeful.

Although this material is completely theoretical analysis and has not been proved by experiments, every derivation process is perfect and completely logical, so Liu Lang feels that the feasibility of this material is very high, and it can be more than 80%.

"It seems that I will report this matter to the higher authorities as soon as I go back, and this is likely to be another turning point in the national large aircraft program!"

Jiang Botao's idea is not wrong, with the drawings of the An-225 aircraft engine before, and today the information on the new alloy material has been obtained, isn't this everything ready? When the country started the large aircraft program, it was expected to take 15 to 20 years, which was a very long time, so long that it would take two or even three generations of joint efforts, and as a result, God helped China, the Soviet Union fell, and some precious materials fell into the hands of the state, and with these precious materials, the time of the country's plan was almost shortened at a rocket-like speed.

Jiang Botao estimated that this plan may achieve a breakthrough within five years, and perhaps the country will be able to build its own large aircraft in this century.

Jiang Botao stayed in Fucheng for three days, and in addition to the North Industries Group, he also inspected other manufacturing enterprises, not to mention cheering everyone on.

He felt that it was really worthwhile to come to Fucheng this time, especially the "Exploration No. 1" CNC machine, which made him very excited.

Three days later, Jiang Botao left Fucheng and returned to the capital by noon plane, and reported to Bai Weiren as soon as he arrived in the capital.

"What? Liu Lang built a CNC machine?"

Bai Wei was also shocked when he heard it.

"That's right, I didn't know about this matter in advance, and I saw it for the first time when I arrived in Fucheng!"

"Ha, this is Liu Lang's style, I guess he will say: This is nothing, after all, the chip is not independent research and development, did he say so?"

Bai Weiren said with a smile.

"It's not wrong for Premier Ren to guess at all, Liu Lang called it a servo system, but he has already cooperated with SMIC to start developing his own chips, and it is likely to achieve a breakthrough within a year, and then this exploration No. 1 is a well-deserved domestic machine tool!"

Jiang Botao still couldn't suppress his excitement when he said this.

"Okay! this little guy is really a genius, it seems that there is nothing that can't be done, the country's manufacturing industry depends on him, I must look at this machine tool when I go to Fucheng in two days, to see what our country's first CNC machine tool looks like!"

Bai Weiren was also very excited.

"That's right, for the prime minister, this is the information that Liu Lang got from Kaminsky, Shougang, Shanghai Iron and Steel and Anshan Iron and Steel have a copy, and this information is a set of improved design drawings designed by Liu Lang for the large aircraft engine plan, together with the engine materials, he asked me to hand it over to Qin Lie experts, I think it is necessary for us to have another matchmaking meeting, so that the heads of the three steel mills and the scientific research team can unite to form a joint team, and I can serve as the team leader. ”

Jiang Botao felt that the national large aircraft program was very important, and he should immediately hand over these materials to the scientific research team.

"Well, this is a good way, just do what you suggest, by the way, bring these departments here, I will personally hold a meeting for them, no, I will be the team leader, you should be the deputy team leader!"

"That's great, if you are the head of this group for the prime minister, I am afraid that the big plane plan will be completed in the nineties. ”

Jiang Botao called the heads of several departments over according to Bai Weiren's instructions, the headquarters of the large aircraft research and development team is in the capital, but the test base is in Xichuan Province, and the Shencheng Aircraft Factory is also the main department, Qin Lie, these experts are now working without sleep and food, and they are a little angry when they hear that they are going to the capital for a meeting, even if Bai Weiren personally presides over it, now his work has entered the fast lane, and there is progress every day, and the state can just give money, what do you do when you hold meetings every day?

But when they heard that Liu Lang wanted to give them some precious materials, it was like being beaten with chicken blood, and they got great benefits from Liu Lang, and it was because of him that the research and development time of the large aircraft would be greatly shortened, maybe these old people could see the scene of the plane in the sky.

Qin Lao hurriedly came to Bai Weiren's office with a few assistants, and the leaders of various ministries and commissions in the conference room were there, and the standard of the meeting was very high.

As soon as he sat down, a secretary placed a stack of documents in front of him.

"So much conference material, a bit of a waste!"

Qin Lao muttered for a moment, then flipped through it casually, and was immediately attracted to it.

"Oh my god.........! What is this?"

Several assistants on the side also gathered around, staring without blinking.

Several people gathered around and looked at the material, and their attention was completely lost.
