Also!

Captain Li and the others immediately reacted, although COMAC can develop this heavy helicopter by itself, but if there is no national project, it means that even if COMAC makes it, this project cannot enter the sequence of national procurement, which means that COMAC is not pleasing to help, of course they cannot do this kind of thing.

The three of them exchanged glances with each other, and they all understood what Wang Dazhi meant: As the final user, should you take the initiative to promote this matter?

"What about the final reducer and rotor?" Captain Li asked, "We don't have a final reducer that can withstand such a high power in China, and we don't have the ability to make such a long rotor, right?"

Wang Dazhi immediately said: "Mr. Victor is the chief designer of the Mi-26 final reducer, he said that he can design the main reducer that meets the requirements, as for the rotor, our company has Chen Dong from the Soviet Union to get back, Mi-26 rotor and rotor head of a full set of manufacturing process information, so whether it is the final reducer or the rotor, there is no big problem." ”

The engine is ready-made, although there is no final reducer, but there is a very powerful man, who has designed a final reducer with a maximum input power of up to 20,000 shaft horsepower, and even has the complete manufacturing process of the Mi-26 main rotor with a length of 14.3 meters......

When Wang Dazhi said this, Captain Li, Lieutenant Colonel Liu and Lieutenant Colonel Chu had already understood the meaning of COMAC: For our COMAC Group, if you really want to imitate the "aerial crane", there is no difficulty that cannot be overcome, and the key to this lies in how much effort you are willing to make for this matter.

Realizing this, the three of them were immediately excited.

Or Captain Li, who was calm enough, held back the excitement in his heart and asked Wang Dazhi: "Mr. Wang, if this project is approved, how long will it take for you to come up with a prototype at the earliest?"

"I asked Victor this question, and Victor told me that it took Sikorsky only 13 months from the start of the project to the completion of the first prototype, and he believed that Captain Li and your squadron must have accumulated a lot of useful information in the use of the 'aerial crane' over the years, and if you can provide this information to us and fully cooperate with our surveying work, he will only need 9 to 10 months to complete the first prototype. ”

Speaking of this, Wang Dazhi couldn't help but sigh, and Viktor Vladimilovich Kapaya was after saying this. With a regretful face, he said that the talents and accumulation of COMAC in the field of helicopters are too small, and if it is in the Miri Design Bureau, it will not even take half a year.

However, there is no need to say this kind of morale.

"Only 10 months?"

Captain Lee's eyes widened.

"Yes, only 10 months," Wang Dazhi nodded affirmatively: "And Mr. Victor also said that he can increase the maximum input power of the final drive to 10,000 horsepower, and increase the length of the rotor from the current 10 meters to the length of 11.6 meters of the three-engine version of the CH-54B 'Tach' that Sikorsky had planned but did not produce in the end, that is, the diameter of the rotor will be more than 24 meters."

In this way, not only will the maximum payload be more than 13 tons, but there will also be plenty of room for future upgrades, if in the future our turboshaft-2000 is upgraded to turboshaft-2500, then the maximum payload of this aircraft will be increased to 16-17 tons. ”

The maximum payload reaches 13 tons, and it can even be 16 to 17 tons in the future, at this moment, Captain Li, Lieutenant Colonel Chu and Lieutenant Colonel Liu's eyes lit up: You must know that the S-64E "aerial cranes" that are regarded as baby bumps in the military region are actually military CH-54A "Tahe" After dismantling some special equipment of the US military, the maximum payload is only 10.3 tons.

Lieutenant Colonel Chu forcibly held back the excitement in his heart and took a deep breath: "Mr. Wang, you can't joke about this kind of thing. ”

"Who dares to joke about this kind of thing?" Wang Dazhi smiled: "I dare to sign an agreement with you." ”

Lieutenant Colonel Chu, Lieutenant Colonel Liu and Captain Li stopped talking, they all felt the strong self-confidence of Wang Dazhi and COMAC......

........................

Captain Li and the others went back, Wang Dazhi knew that this kind of thing was in a hurry, but he was not in a hurry, he was most concerned about the test ship now.

After completing a three-month sea trial, COMAC's test ship carrying the first gas turbine with a maximum power of more than 23,000 horsepower in China is back!

Although in order to obtain first-hand information, in addition to the COMAC Group, the Navy, the West-East Gas Transmission Project Team, the National Offshore Oil Corporation and several other systems have stationed observers and technicians on this ship, in order to be able to grasp the first-hand detailed information, these units also know well enough about the experimental process of the ship at sea, but when the ship returned, each unit still coincidentally sent their own technical teams- What kind of performance does the high-power gas turbine produced by Huaxia have in such a highly complex and demanding environment as the ocean?

Wang Dazhi attaches great importance to this matter, he personally led the team to the port, and saw the RB211 technical team members who got off the ship, much darker and thinner, he took a deep breath and said to Fang Zhiqiang, the leader of the project team and the chief engineer of the RB211 gas turbine: "Old Fang, you have worked hard, everyone has worked hard. ”

"Report to the general manager, we are not hard," Fang Zhiqiang said with a smile: "On the ship, we eat and sleep well, four people in a room, the room has air conditioning, and there is no shortage of fish, meat and vegetables. ”

The technical team members behind Fang Zhiqiang immediately burst into laughter.

Looking at the mental outlook of the whole team, Wang Dazhi was relieved, if it weren't for the extremely good effect of this overseas test, everyone would not be so relaxed.

Realizing this, Wang Dazhi immediately breathed a sigh of relief, and he asked Fang Zhiqiang in a low voice: "Old Fang, how is the situation?" Well, you can talk about the specific situation when you go back, just tell me a rough idea now." ”

Fang Zhiqiang didn't sell it, he said excitedly in a low voice: "Mr. Wang, I can only say that the foundation of the RB211 aero engine is really good, after it becomes a gas turbine, the performance of this gas turbine is beyond our imagination, you can celebrate the wine in vain." ”
