To the disappointment of both the Americans and the French, in the face of the defeat of General Electric and Pratt. The persecution of CFM International and IAE with Whitney as the background, the Republic did not give in: for the Republic, it is nothing if we do not provide us with engines, we are not unable to take off without their planes, let alone lose underwear without their engines, in the current civil aviation industry, fuel costs only account for about 15% of the total cost, and BD1000 is only about 30% higher than the fuel consumption of similar Western productsThe BD1000 engine, which has relatively high fuel consumption, does not have much impact on the aviation enterprises of the Republic.

On the contrary, the British, because they had received a large number of shipping orders, behaved a little ambiguously, although they also shouted a few slogans behind the Americans, but there was no substantive action.

Americans took this matter very seriously, and by the beginning of '97, even the FAA had come forward and said that "the testing of the North County 100 is a long process", a statement full of hints and threats.

But Lin Hongfei has never been a person who is easily hit by pressure, targeting General Electric and Pratt. Whitney's suppression, Lin Hongfei did not show weakness to announce the next step of the AVIC Second Group's research and development plan: "We will make further improvements on the basis of BD1000, by expanding the bypass ratio, increasing the compression ratio and other ways to increase the thrust to 150 kN, we expect that the development of the improved engine will be completed within 3 years." ”

Increase the maximum thrust of D-30KU from the current 126.8 kN to 150 kN in three years? For a time, the Americans were silent!

What is the concept of 150 kN thrust? This is equivalent to the thrust of the CFM56-7B turbofan engine used in the 737-800 aircraft just announced by Boeing two years ago, and the famous C-17 "Globemaster III" large transport aircraft uses Pratt. The thrust of the PW2040 large turbofan engine manufactured by Whitney is only 180 kN, which is based on the Republic's expertise in the design of aircraft aerodynamic shapes. The thrust of 30 kN is enough to make up for it by the improvement of the aerodynamic shape, which means that if the Chinese decide to build a large transport aircraft such as the C-17, the biggest problem: power, is no longer the most important constraint.

As soon as Lin Hongfei's expression with a strong taste of provocation and retaliation came out, the entire United States was silent for a while: How dare the Chinese?!

But before the Americans could come back and discuss countermeasures against the tough response of the Chinese, in July, AVIC Group 2 once again announced a piece of news that made all Westerners feel more and more unpleasant: "After nearly half a year of continuous testing, it has been proved that the performance of the BD1000 engine is stable and reliable enough, and the new BD1000 turbofan engine will be used as one of the alternative power for the North County 200A/B aircraft. At the same time, AVIC No.2 Group welcomes major aero-engine manufacturers in the world to provide supporting engines for the North County 100 and North County 200. ”

As soon as the news of AVIC No. 2 came out. Suddenly put the Americans and the British in a dilemma.

On the one hand, after the delivery of Beijun 100 has been widely praised by Chinese users and customers, the market position of Beijun 100 has been unshakable. It is also enough to ensure that the North County 100, together with subsequent improvements, will be able to win a market share of no less than 1,000 aircraft in the next 20 years. How could European and American aero-engine manufacturers, who have long regretted this and their greedy eyes red, let go of such an opportunity?

But in another way. AVIC No. 2 Group, which already has its own engine, obviously will not buy engines from itself according to the original market...... If the engine is too expensive, they can use their own production, before they wanted to open whatever price the Chinese had to accept, the real store bully, but now it is different. Although Westerners shout "the customer is God" all day long, when one day the customer is really likely to become God, it is when they are most depressed.

Can you pass up this opportunity? If you don't give up this opportunity, you can also get a piece of the cake. But if you give up this opportunity, you won't even get a bite of the cake.

Westerners are struggling, Lin Hongfei is not in a hurry, in Lin Hongfei's opinion, the longer these guys delay, the better it will be for themselves.

The leisurely boss Lin put most of his energy into the Beijun 200, which has entered the most advanced stage of airworthiness certification: if the Beijun 100 is the stepping stone for AVIC Second Group to enter the large civil aircraft, then the Beijun 200 is the real big killer...... and machine guns of the same nature, belonging to the type of "sweeping a large area".

Only a very small number of people know that Lin Hongfei is not only paying attention to the North County 200A/B, but also paying attention to the two military modified special aircraft derived from the North County 200B: large air tanker and large air early warning aircraft.

The air tanker and air early warning aircraft based on the North County 200B have been accompanied by the project as early as the beginning of the development of the North County 200, the maximum commercial load of 23 tons of Il-62M was originally as high as 83.3 tons, a large number of applications of new technology and new materials have made the weight of the North County 200 have been greatly reduced, after strict and scientific calculations, after structural weight reduction and material application, the maximum commercial load of the North County 200B type of the international route has been increased to 30 tons.

Compared with D-30KU, BD1000 turbofan engine provides more thrust at the same time, compared with D-30KU is also more fuel-efficient, fuel consumption is 10% lower than D-30KU engine, with modified aerodynamic shape and wing, the maximum range of BD200B using BD1000 engine from 9600 km of IL-62M to 12800 km now, the maximum full load range of 11400 km, enough to achieve intercontinental flight across the Pacific Ocean.

The air tanker modified on the basis of the North County 200B, after removing the necessary seats, air conditioning, cockpit pressurization system, life support facilities and other equipment necessary for civil passenger aircraft, plus the internal fuel tank, the maximum fuel load of the aircraft has reached a terrifying 135 tons!

The new large air tanker has a maximum range of 135 km with a full load of 17000 tons of fuel. It can be called the farthest flying large air tanker...... This is a very proud thing, but at the same time, it is even more helpless, who let us not have overseas military bases, and there is no way to deploy air tankers overseas, so we can only solve it through this method.

For a mission with a 3,000-kilometer flight radius and hovering in the mission area for an hour and a half, 65 tons of fuel can be supplied to the aircraft that needs to be refueled, and for a mission with a 2,000-kilometer flight radius, up to 85 tons of fuel can be used to supply the combat aircraft!

This number may not be so intuitive, so let's change to a more vivid analogy: when there was a war in the Dark Sand generation of our great-mother, our seventh and eighth masters' legs were not long enough. After flying to where the remaining fuel could not be returned, but now that there is a tanker, an air tanker full of fuel takes off from the southern tip of Hainan Province, the southernmost part of our country, and the seven and eight masters at the same time, when the seven and eight masters fly to the mission area and there are still hundreds of kilometers away, a squadron of planes on alert. The remaining planes are refueled about one ton in turn, and the fuel in the fuselage of the seven and eight masters is enough to ensure that they can carry out combat or patrol missions in the mission area for about an hour. An hour of time. No matter what, the battle is over.

When the battle or patrol mission is over, when there is still a distance of about 500 to 700 kilometers from our coastline, the fuel of the seventh and eighth masters has reached the warning line, and at this time, the air tanker that was accompanied by the seventh and eighth masters flew back just to provide air refueling for the seventh and eighth masters, and the seventh and eighth masters flew back to the air base on the mainland safely.

If the KY-200 can be put into service quickly, the significance is huge. This means that the South China Sea, which we could not effectively control, will soon be able to achieve effective control after having a large air tanker!

Not only that, the cabin space of the North County 200 is simply too large. Even if the fuel tank is added, the original cargo space is used, the upper passenger compartment is still empty, and the cabin is reserved for simple seat installation interfaces, if necessary, the aircraft can be transformed into a transport aircraft with ultra-long-range flight capability by reducing fuel load, adding temporary seats, and flying at low and medium altitudes to ensure the temperature and air pressure in the cabin.

The airborne AWACS aircraft modified on the basis of the North County 200 is also powerful, with a maximum fuel carrying capacity of 90 tons, and has the ability to receive fuel in the air, and if necessary, it can be on duty in the air for more than 36 consecutive flight hours by means of multiple in-flight refueling...... This was also a special request of the Air Force, for which it had to be equipped with four sets of flight and control teams on one airborne early warning aircraft.

The only regret is that Israel is now arguing with the Republic over the matter of the "Filcon" early warning radar/air command and control system, and the smooth take-off of the North County 100 and North County 200 has made the Americans angry and "started" to put pressure on the Israeli side.

Lin Hongfei, this bastard, was really a prophecy back then, and the current Beijun 200 airborne early warning aircraft just made a set of full-size and full-weight counterweight models based on the data of the "Filcon" system provided by the Israeli side for testing...... This "model machine" is still in the manufacturing stage.

PS: Because of the general climate, although the ban on "The Family" has been lifted to a limited extent, everyone can only see the update through the bookshelf, and the site search, monthly pass rankings and VIP updates are not visible, and the advice given by the editor is to quickly finish the book and open a new book.

But I'm not very happy to do this, the brothers all know that the scene of "The Family" is too big, and if you want to end it all in just 30,000 or 40,000 words, there is no doubt that it can be considered unfinished.

Of course, the climate is like this, even if I write a 10,000-word ending in a thousand years, I guess the brothers won't blame me, the climate is like this, and it can't be reversed by manpower.

But the millennium is still a little unwilling.

If possible, the millennium is not willing to end in any case, even if it is limited to the general climate to end, the millennium also wants to explain as clearly as possible, in view of this, the millennium decided to write a final volume, the situation of the confession is explained one by one, and at least 2 million words of the ending is condensed in this final volume that is estimated to be no less than 100,000 words, although it is certainly very hasty, but it is definitely better than the unfinished or TJ.

So, the final volume appeared, because the number of words is small, and it is a little hasty, there may be some places that have not been explained, Wanwang brothers Haihan, this is really not the millennium intentionally, this is already the limit of the millennium can be strived for, I believe that the loss of the millennium can be seen by everyone, a book is like the author's child, the author always wants to see the child grow up healthy and healthy, right?

Okay, it's a bit messy, because the heart of the millennium is actually quite messy, but the general meaning is still clear, and the brothers can forgive it, right? (To be continued......)
