Chapter 835: Three reasons

Following in the footsteps of Tan Zhenhua, the guests of Ibos walked into another spacious and bright room. In this room, two people were already standing there with smiles. Obviously they had been waiting for a long time. One of them had hair. White, looks over 60 years old, and the other is a middle-aged woman.
In addition, in the middle of the room, there is also a huge cylindrical object, but because it is covered with a large red silk cloth, it makes people dimly indistinct. However, after the passage just now , The hearts of all visitors inevitably have quite consistent guesses about the objects hidden under them.
"This is the veteran of our China Aviation Engine industry, Mr. Wu Daguan. He is currently in charge of our country's strategic planning in this field." Tan Zhenhua casually pulled a top hat on to the old man, and then squeezed at Wu Daguan. Eyes, and the old man was quite calmly praised by him and met the guests at first sight.
"This is Ms. Li Mengzhen, the chief engineer of our Xijing Aero Engine Factory and the chief technologist of a certain aviation model."
When the heroine was introduced, Tan Zhenhua was really much, and the two titles he mentioned made all the Ipos visitors even more convinced of their guesses.
"Everyone, you must be very curious, why I will lead you here again after I visited the TF41 engine just now." Tan Zhenhua cleared his throat and said loudly: "Mr. Jalari just showed a great deal with us. Ability doubt, this is obviously detrimental to the promotion of cooperation between our two parties. Of course, as a customer, we have every right to question, and as a manufacturer, we also have an obligation to help customers dispel doubts. Then, for a manufacturer In other words, how can we dispel the suspicion of customers to the maximum extent?"
He paused and raised his voice and said: "In China, there is an old saying that "hearing is false, seeing is believing", which means that he will believe it only when the customer sees it with his own eyes. For such high-tech products, I also think that only by letting customers see our successful products with their own eyes can they gain his trust. So, everyone, please see!"
While talking, he walked to the huge silk-covered monster in the house, grabbed a corner of the silk with one hand, motioned to Li Mengzhen on the other side to help him, and yelled in his mouth: "Please see our China Hangfa’s most outstanding manufacturing achievement: "Speey" MK202 turbofan afterburner engine!"
The silk cloth was torn off, and the behemoth finally revealed its true body. Sure enough, everyone could see that it was indeed a turbofan engine, and those with sharp eyes or a little more skilled could even see that this engine There are many similarities and differences with the one just seen.
Tan Zhenhua’s introduction sounded immediately: "The Spey MK202 engine is 5205 mm long, 1093 mm in diameter, and 1842 kg in mass. Under the current state of the art, the military has 5.55 tons of afterburner thrust, 9.3 tons of afterburner, and a thrust-to-weight ratio of 5.05. The bypass ratio is 0.62, and what I need to emphasize is that this engine has a first rollover period of 850 hours and a full life span of 2550 hours. It is a fairly mature and reliable engine!"
There was another "buzzing" discussion in the crowd of onlookers, but Tan Zhenhua continued to introduce as if he hadn't heard: "And there are three reasons why I showed you this engine. First, this This engine has a very deep relationship with the engine you just saw, because the TF41 just now was developed on the basis of this engine; second, we have achieved localization of this engine, that is Say, if we want to purchase it, we can accept the order at any time."
Jaralli, who was already a little impatient, immediately stepped forward and asked: "Eric, do you confirm that China can start supplying this engine immediately?"
Tan Zhenhua nodded proudly, and added: "If you are in a hurry, we can even provide some stocks, which are stocks. Pay immediately and pick up the goods immediately!"
"Then do you think it is possible for this type of engine to match the F-14 fighter?"
It can be seen from this question that looking for suitable accessories for their own Air Force ace has become the demon of the arms procurement personnel of Ibos.
Tan Zhenhua shrugged his shoulders and shook his head again: "I don't know. No one has ever tried this. But I can ask an expert to answer your question."
"Let me answer." A slightly old voice sounded, and Jalari looked over and saw that it was the veteran of China Aviation that Tan Zhenhua had just introduced.
"Mr. Colonel, changing aircraft engines is a very complicated project. Theoretically speaking, if the thrust can meet the requirements, there is the possibility of replacement. However, there are a lot of troubles in actual operation. For example, it may be because of the new and old engines. The size is different, and it is necessary to repair the engine compartment or design and manufacture special mounting brackets. For example, it needs to re-test the influence of the new aircraft on the flight envelope of the aircraft. If it is a fly-by-wire aircraft, it may also need to be reprogrammed. Control code."
Jalari is not a layman, and he nodded in agreement after hearing these words.
Wu Daguan continued:
Therefore, the replacement of aircraft is a complicated and long process. It does not mean that it can be replaced. Generally speaking, it takes at least a few hundred hours to fly after the replacement. , Or not, worth it, or not worth it."
Jalari nodded again, and Wu Daguan continued: "Then I will answer your question just now, can I replace the F-14 with this engine? My answer is that given the thrust and thrust-to-weight ratio of this engine, TF30 is not much different, so it must be ok, but is it worth it? I think it is not worth it, because you have spent a lot of work and replaced it with an engine that is not much different from the original performance? If you have no choice, then the price may be worth the cost. If you have a better choice, then why not use a better solution?"
The old man said to Jalari's heart, he couldn't help but nodded frequently, and then thought of the performance parameters of the TF41 that Tan Zhenhua introduced just now, he felt that he had a choice.
"Mr. Colonel, I introduced this "Speey" MK202 engine to you. I didn't want to recommend you to install it on the F-14. As Mr. Wu said just now, it's not worth it. In fact, I didn't finish what I said. , At least my third reason hasn’t had time to say it.

"Oh, Mr. Eric, I'm sorry, I interrupted your speech impolitely just now, so now, please tell me, what is the third reason for taking me to see this engine?"
"Haha, it’s okay, Mr. Colonel, before I say that, I have to ask you a question. Do you know what type of engine is installed on the carrier-based F-4 "Phantom" fighter jets equipped by the British Naval Air Force? ?"
