The engine of the weakest chicken has a power output of 4050 horsepower, and the maximum power output of the engine of the most bull X can reach 4800 horsepower?

Chen Geng's explanation made Li Jianguo directly not know what to say, and he only felt deep helplessness in his heart: Awesome! The technology of the Americans is really awesome.

Speaking of pity, there is no decent helicopter special turboshaft engine in China, even if it is matched for the straight-6 helicopter and improved on the basis of the turboprop-5 turboprop engine, the maximum power is only 2200 horsepower (as for what service life, first turnover, easy maintenance, fuel consumption, Reliability and the like, we won't mention it), a turboshaft engine with more than 4,000 shaft horsepower, as Chen Geng said, is really far beyond Huaxia's current industrial strength.

If you have to make an analogy, the difficulty of the core engine of the JFTD-12A series turboshaft engine from Pratt Whitney is even slightly more difficult than the "Spey" MK202 turbofan engine we imported from Rolls-Royce in the United Kingdom.

Chen Hongjun also understood a little, and he couldn't help but say: "This...... Even if we can't produce engines and drivetrains for the time being, we can buy them from the Americans, right?"

Since the Americans have even sold us the technology, is it possible that they will not sell us engines?

Chen Geng looked at his father with a smile, and it wasn't until Chen Hongjun saw a burst of hair in his heart that he said with a smile: "Maybe you can try?"

Li Jianguo glared at Chen Hongjun angrily, signaled him not to talk nonsense, and then cautiously asked Chen Geng: "Mr. Chen, what do you mean...... Not very optimistic?"

Chen Geng shrugged his shoulders and said, "It can't be said that there is no hope at all, it's just very slim." Oh, by the way, tomorrow Sikorsky will show you the performance of the 'aerial crane', and will also recommend their 'Black Hawk' helicopter to you by the way, compared to the JFTD-12A series engine on the 'aerial crane', in fact, I recommend you to try to introduce the 'Black Hawk' on the General Electric T700-GE-700C turboshaft engine, even if the performance is slightly inferior T700-GE-700. ”

It is simply unbearable to say, Huaxia in the helicopter turboshaft engine and the world's gap, simply throw the fighter with turbofan engine several streets, when the Huaxia fighter has begun to be equipped with turbofan - 10A "Taihang" series engine, the power problem of general helicopters and armed helicopters is still a big problem, if you can take advantage of this rare opportunity to introduce the old United States T700 series turboshaft engine...... Although Chen Geng was very clear about Huaxia's attitude towards helicopters at this time.

Sure enough!

Of course, Li Jianguo knew about the famous "Black Hawk" helicopter, and when he heard Chen Geng recommend the turboshaft engine on the "Black Hawk" helicopter to him, he raised his eyebrows and asked, "How is the performance of this engine?"

"The civilian S-70 and the first batch of military UH-60 use T700-GE-700, with a maximum power of 1560 horsepower, and the subsequent improved version uses T700-GE-701A/C, with a maximum power of 1927 horsepower, oh, by the way, this engine has put a lot of effort into reliability, even if the oil is all leaking, the engine can still work for half an hour. ”

The lubricating oil is all leaking and can still work for half an hour?!

Chen Hongjun and Li Jianguo were all dumbfounded, such technical indicators were completely unimaginable in their opinion: Lao Mei is really ...... Awesome!

"In my opinion, the power of the JFTD-12A series is completely excess for the next two or three decades of Huaxia's demand, on the contrary, through the superposition of the number of engines, the T700 engine can meet the power needs from 6 tons to 15 tons, from general helicopters to armed helicopters.

In terms of the difficulty of introduction, the T700 is also lower than of course, if you choose, it is your problem, I just make such a suggestion. ”

Speaking of this, Chen Geng added: "Oh, by the way, the T700 engine is also the queen engine of the new generation of armed helicopter 'Apache' that has not yet been officially put into service by the US military, so the problem now is not that you can introduce it if you want to, but that even if you want to introduce it, the Americans may not be willing to let go." ”

Chen Hongjun and Li Jianguo's eyes subconsciously widened.

Of course, they know the "Apache" helicopter gunship, and this is a new-generation heavy helicopter developed by the US military because of the shortcomings of the "Cobra" helicopter gunship in terms of power, attack power, and firepower, and has pushed its maneuverability, firepower, and computer-aided control to a whole new height.

The depth of China's involvement during the Vietnam War does not need to be said by others, as long as you look at the emotions of the Chinese in the self-defense and counterattack war against Vietnam later, you can understand how much we helped the Vietnamese in that war, naturally, we also have some understanding of the performance and powerful combat effectiveness of the AH-1 "Cobra" armed helicopter that shined during the Vietnam War, the "Cobra" armed helicopter has become so powerful, and the power of the new generation of "Apache" armed helicopter is still needless to say?

Conversely, as the power of the "Apache", the performance of the T700-GE-700/701C, does it need to be said?

Chen Hongjun's face turned red all of a sudden.

Originally, he felt that the introduction of the T700 engine was dispensable, compared to the T700 or the "aerial crane" JFTD-12A is more powerful, after all, the performance of JFTD-12A is stronger, but now it seems that it is indeed as Chen Geng said, it seems that T700 is more suitable for the current China - the main question is whether the Americans are willing to sell the technology of the T700 turboshaft engine to us?

"This ...... Mr. Chen, it's me who has eyes and doesn't know gold and jade," Li Jianguo immediately pulled Chen Geng to apologize: "You must help us find a way......"

"This ...... Let's take a step at a time," Chen Geng waved his hand: "It's too early to mention this, let's get this batch of helicopters done first, and then talk about other ...... Having said that, this is all our own grinding teeth here, maybe your country's high-level leaders don't plan to introduce the T700 at all after discussion?"

Chen Geng's words seem to have some truth, but Li Jianguo has already made up his mind after knowing the Niu X of the T700: if the domestic leaders do not plan to introduce the T700, even if they poke out this military uniform, they have to explain this matter to the leaders, and do their best to persuade the leaders to introduce this engine!

————————————

"Really...... Big ......"

Looking at the S-64 "Sky Crane" heavy helicopter in front of him, which was painted orange and owned by Sikorsky Helicopter Company, Li Jianguo's eyes were full of shock.

The other leaders of the delegation nodded unconsciously, and their eyes were full of shock: How can a helicopter be so big?

It's no wonder that everyone has such an idea, but the helicopter in front of you is really big: the rotor diameter is 21.95 meters, the tail rotor diameter is 4.88 meters, the fuselage length is 26.97 meters, and the fuselage height is 7.75 meters. If you make an analogy, it is roughly equivalent to a three-unit two-story red brick residential building that can be seen everywhere in China...... And it's a little bit higher.

Grabbing the "hair" of a three-unit two-story residential building and flying vertically, how exaggerated and awesome do you say the performance of this plane is? It is understandable that the leaders of the Huaxia delegation were shocked and speechless: Although you have seen many pictures of this helicopter before, the pictures cannot match the shock of standing in front of this helicopter.

Cyrus Roberts Vance, who acts as the narrator himself, is well-dressed and takes the lead: "Gentlemen, compared to the traditional helicopter, our 'aerial crane' has a revolutionary structure with a third rear-facing pilot's seat, who is responsible for loading and unloading the cargo, observing the condition of the cargo throughout the flight, and ensuring that the entire flight and lifting process is foolproof.

In fact, the cockpit of the aircraft can accommodate up to five crew members: the co-pilot, the rear-facing pilot, and two mechanics.

Because the helicopter was designed to require intensive work over long periods of time in remote, inhospitable areas where maintenance support is impossible, two additional mechanics were a must......

…… In addition to this, we have taken a lot of measures to help users save costs, such as here...... Please come with me, everyone, and please slow down when you get on the gangway...... It's here, the engine and gearbox, don't you think it's strange, why is there no fairing here? It's just that we designed it this way, because the flight speed of this helicopter is not fast, it doesn't matter whether there is a fairing or not, and at the same time, it can also simplify maintenance, reduce costs, and reduce weight - not a kilogram of weight on the fuselage means an extra kilogram of load capacity.

It is by virtue of these ingenious designs that the empty-weight and total weight ratio of the 'aerial crane' is very amazing, as low as 0.42, and the flight performance is even more amazing when not loading, and has broken a number of altitude and climb records, and the maximum level flight altitude has reached an astonishing 11,010 meters. ”

With Chen Geng's translation, Cyrus Roberts Vance's words caused bursts of exclamations from time to time.

Many comrades of the Chinese delegation are still knowledgeable, and it is precisely because they understand the helicopter that they are even more shocked by the technology, ability and powerful performance embodied in this helicopter:

What is the ratio of empty weight to gross weight of 0.42?

Oh, my God!

Generally, helicopters can have an empty-weight total weight ratio of 0.3, which is enough for them to brag about X;

A maximum level flight altitude of 11,010 meters?

Doesn't that mean that the helicopter can easily cross Mount Everest?

It also means that the powerful plateau performance of this helicopter - compared with the former, the plateau performance is what Huaxia values the most.
