"Hiss~~" As soon as Lin Hongfei's words came out, everyone let out a cool breath in unison!

Everyone is a top expert in domestic aviation manufacturing and design, and the data of various aero engines in the world are memorized like a stream, Lin Hongfei's plan is not feasible, what is feasible, and what will be the approximate performance of the aircraft after it is designed, which can naturally be distinguished at a glance;

The data of using three TV3-117TM engines with a load of 2 tons for vertical take-off and 2.8 tons for taxi-run take-off is still very reliable...... Although the weight of the aircraft is at least 2 tons more after adding wings and tail rotors and replacing them with vector thrust ducted propellers, the forward-swept wing brings greater lift, and it is a taxiing take-off, and it is really not a big problem to take off with a load of 2.8 tons.

It is true that Lin Hongfei's design can only be regarded as a sketch, and in the eyes of the experts present, it seems that there are still many imperfections and unreasonable points, such as whether the tilt angle of the vertical tail should be recalculated? But the most important and valuable thing is Lin Hongfei's idea!

Since this line of thinking is correct, as long as it follows this line of thought, the Republic's aircraft carrier carrier-based early warning aircraft will definitely be able to succeed! That's all that matters.

How did this kid's head grow? This ability to diverge in thinking is really terrifying!

"This involves another core component: the final reducer," Lin Hongfei, who looked at him with admiration around, could naturally see it, and breathed a sigh of relief in his heart, so he continued, "My assumption is that scheme A without wings still adopts the traditional design idea of the final reducer, but whether scheme B can make some improvements on the basis of the existing final reducer, the improvement idea I envisage is as follows: when the aircraft takes off, when the flight speed reaches a certain value, The power output of the engine gradually changed from mostly supplied to the main rotor to most of the vector thrust ducted propellers at the rear, when the speed reached a certain speed. For example, at 300 km/h, the power of the engine is fully supplied to the vector thrust ducted propeller, and the vector thrust ducted propeller propeller propeller propels the aircraft to fly. At this speed, the main rotor of the aircraft is already able to rely on its own spin effect to rotate to provide a part of the lift, plus the lift provided by the wings, which means that the aircraft at this time has become a hybrid of a rotorcraft and a fixed-wing aircraft. ”

"This is a good idea, if it is improved according to this idea, it can effectively reduce the load of the engine, and probably reduce the cruising power of the engine to the extent that it is equivalent to about 50% of the take-off power?" Li Zaijian, as the chief designer of the Z-8 helicopter, heard Lin Hongfei's idea of improving the final reducer. His eyes lit up immediately, first he muttered to himself, and then looked at Lin Hongfei excitedly, "But the core of this idea is the final reducer, how to adjust the power distribution of this main reducer." Mr. Lin, do you have a plan? ”

Inadvertently, Li Zaijian used honorifics to Lin Hongfei. Apparently. At least Lin Hongfei's divergent thinking ability in aviation design has been affirmed by him.

For the relatively backward aero engine industry of the Republic, the turboshaft engine is a common pain in everyone's heart, and its performance indicators are also the most demanding among the aero engines, not only because of the harsh working environment, but also because of the special flight mode of the helicopter so that the load of the turboshaft engine is very heavy, as long as it is in the flight state. Even if it is lightly loaded, the minimum output power of the engine must reach more than 65% of the full power, and now the cruising thrust of the turbofan engine with a large bypass ratio is even only 1/5 or even 1/8 of the take-off thrust, and even the cruising power of the turboprop engine is only 1/3 to 1/2 of the take-off power. If the cruising power of the engine can be reduced to about 50 percent of the take-off power, the Republic will soon be able to build an engine that can meet the requirements of the aircraft carrier's early warning aircraft platform on the basis of the existing aviation engine.

"There is really no solution, this technical problem is too much beyond my imagination," Lin Hongfei smiled very shyly, very embarrassed, "but I personally think that we can learn from the concept of continuously variable transmission in scooters." ”

"The idea of continuously variable speed on a scooter?" Li Zaijian was stunned for a moment, frowned and thought about what the infinitely variable speed of this motorcycle was, and the next moment, he was ecstatic, "yes, why didn't I think of it?!" ”

yes, how did I not think of the idea of continuously variable transmission on scooters? Not only Li Zaijian, but also Guo Jingshan and several other experts in helicopters and aero engines were also pleasantly surprised, and hope was just around the corner, and everyone seemed to have seen the dawn of success.

Lin Hongfei was rare to be modest and low-key, and when the faces of the experts showed excited or thoughtful expressions, he continued, "The third question, that is, the problem of the flight control system, we have some ideas for this. ”

Do you have an idea for this as well? The expression of the Standing Committee of the Wan Surname Bureau is not so good-looking: You kid is here to deliberately slap me in the face today, right?

"Yes, we have," as if deliberately against the Standing Committee of the Wan Surname Bureau, Lin Hongfei nodded heavily, and said affirmatively, "According to the country's previous plan, it is ready to assign the 631 Institute responsible for the research and development of airborne and missile computer systems to us, because of such a relationship, I have exchanged some ideas with Wu Wenqing, director of the 631 Institute, and Fang Hsinchu, chairman of the Inspur Group, who developed the first small server in our country. We are ready to jointly develop our own central processing unit, positioning in the field of special industrial control chips and airborne computer systems, and further develop our own data bus and flight control system on the basis of our own airborne computer system, which has been submitted to the state for approval...... This system is also the core of the flight control system, and with this, our country will no longer have to import expensive airborne computers from abroad. ”

After this project was reported, it was stuck by the Ministry of Science and Technology, but it was not approved, Lin Hongfei did not understand the rules, and knew the meaning of the Ministry of Science and Technology, but those bastards in the Ministry of Science and Technology had too big an appetite, and it seemed that they felt that it was not easy to catch the fat sheep this time, how could they be worthy of themselves when they let go easily? Although Guqi Provincial Industrial Manufacturing Co., Ltd. has already "meant", it still bites and does not let go, waiting for Guqi Provincial Industrial Manufacturing Co., Ltd. to continue to "mean meaning": Anyway, the approval power of the project is stuck in my hand, and you have the ability to bite me!

For this matter, Lin Hongfei has been on fire for a long time, and he has long seen that the Ministry of Science and Technology is not pleasing to the eye, this time he seized the opportunity, how can he seize the opportunity to give the Ministry of Science and Technology eye medicine?

Sure enough, as Lin Hongfei expected, when he heard Lin Hongfei's words, he immediately frowned, turned his head and asked the prime minister in a low voice, "Is there such a thing?" How do I not know the way? ”

This kind of project is still stuck? What the hell are the bastards from the Ministry of Science and Technology thinking?!

"I'll ask." The prime minister immediately picked up the phone, and he was also a little unhappy in his heart: the Ministry of Science and Technology is a subordinate department of the Cabinet, and if the Ministry of Science and Technology has a problem at such a time, his face will naturally be gloomy.

After a while, the Prime Minister hung up the phone and lowered his voice to the present day, "There is indeed such a thing, and the Ministry of Science and Technology is approving it." ”

"Still approving? Play the piano around! Today's brows are furrowing more and more, how can he not know that those cats in some ministries and commissions of the central government are tired of it, what does it mean to be reviewing? It seems that Lin Hongfei was "knocked" by the Ministry of Science and Technology, otherwise he would not have sued the Ministry of Science and Technology at this time.

In today's view, Lin Hongfei is willing to take the lead in this thing, it is simply good, the importance of the central processing unit, everyone present understands, even if it is not the kind of commercial central processing unit that the people think in their hearts, but this kind of application in the professional field processor is actually needed for the development of the republic...... It's time for these bastards from the DOT to give it a beating.

"What do you think?" He asked the Prime Minister in a low voice.

"Add it to the Eighth Five-Year Plan and include it in next year's Ninth Five-Year Plan and the Eighth Five-Year Plan." The prime minister of the cabinet knew very well the value of this thing that Lin Hongfei was going to do, and after a little hesitation, he suggested to the present, and made up his mind to go back and clean up the Ministry of Science and Technology.

"Hmm." Today, in response to the voice, it can be regarded as agreeing with the Prime Minister's proposal.

Matthew bastards, you're out of luck this time...... Lao Tzu dares to make money cheaply? Deserve! Hearing the dialogue between the Prime Minister and today, Lin's heart was as comfortable as eating a popsicle on a dog day.

"The last problem, that is, the arrangement of the early warning radar, my preliminary consideration is this: since the top of the fuselage has no room for placement because of the existence of the rotor, then we simply put the early warning radar antenna fairing from the back of the aircraft to the belly," Lin Hongfei picked up the drawing just now, and put another drawing on it, and the huge projection screen clearly showed Lin Hongfei's design plan: a huge "mushroom" unique to the early warning aircraft appeared in the belly position of the aircraft designed by Lin Hongfei.

A big "mushroom" grew on the belly of the plane? The experts were suddenly shocked: this kid, curious! What a great idea!

Yes, in the past, the early warning radar of carrier-based aircraft was either the E-2 series of the US military with a big "mushroom" on its back and took off, or the British "Sea King" early warning helicopter with a "bell" hanging on the side of the fuselage, or the KA-31 hanging a foldable rotating flat panel radar antenna on the belly, but this kid can actually put a "mushroom" under the belly!

Just for this whimsy, you can't admire it! (To be continued......)
