Vyacheslav Ivchenko was really confident enough to say this.

What is the Ivchenko Design Bureau?

They were the only design bureau in the Soviet Union that could develop and manufacture three-rotor aero engines, and the only three-rotor turbofan engine, except for the British Rolls-Royce, was the Ivchenko Design Bureau!

The first three-rotor engine D36 of the Ivchenko Design Bureau has now become the engine of the Yak-42/D of the Soviet Union's short- and medium-range main trunk airliner, and the D-18T three-rotor engine developed from the D-36 technology is also the only super-high-thrust aero engine with a maximum thrust of more than 200kN.

Therefore, for the Ivchenko Design Bureau, which has a rich technical reserve, technology has never been a problem, the problem is whether the Soviet government and the USSR Military Industrial Equipment Committee approve this cooperation project.

Of course, Chen Geng never doubted the strength of the Ivchenko Design Bureau, after the collapse of the Soviet Union, Ermao ate the old book of the Ivchenko Design Bureau and the Antonov Design Bureau, and continued to eat until 30 years later.

Since Vyacheslav Ivchenko said so, Chen Geng also nodded: "Okay, I'll take care of it from the Soviet government and the Military Industrial Equipment Committee, it's good if you have this psychological preparation," Speaking of this, Chen Geng half-jokingly said to Vyacheslav Ivchenko: "If you don't have anything to do during this time, you can actually start working now." ”

Vyacheslav Ivchenko frowned.

He knew that Chen Geng had deep connections within the Soviet government and within the Soviet Military Industrial Equipment Committee, and it was said that the respected Comrade Gorbachev had personally received him several times and held private dinners for him......

"Mr. Fernández, can I ask you a question?" After enduring, Vyacheslav Ivchenko still couldn't hold back, and asked Chen Geng.

No way, this is a common problem of technicians, after finding a problem, if you don't hurry up and solve this problem immediately, your heart will itch like seventeen or eighteen kittens scratching with small paws, uncomfortable.

Although he had already anticipated what question Vyacheslav Ivchenko wanted to ask, Chen Geng still nodded happily: "You say." ”

"Why do you want to develop a civilian aircraft engine with the AI-222-25?" Vyacheslav Ivchenv hurriedly asked: "I have studied your company's products, and it seems that ...... That's not enough thrust to meet the power needs of the Fokker F100, right?"

By increasing the bypass ratio and increasing the total pressure ratio, the thrust of the engine is improved, but limited by the overall potential of the core engine of the AI-222-25 engine, Vyacheslav Ivchenko feels that in the first stage, the civilian version of the engine can only increase the thrust to about 4000 kg at most, and it is necessary to install four Fokker F100 units to basically meet its demand for power. 0-8c No, Chen Geng will risk using the civilian version of AI-222-25?

Vyacheslav Ivchenko always felt that this was unlikely.

"Of course not," Chen Geng nodded affirmatively, but he also explained: "But I don't plan to use this engine on the Fokker F100." ”

"Huh?"

Vyacheslav Ivchenko was stunned for a moment: not on the Fokker F100, is there any other aircraft in your company that can use this engine?

Looking at Vyacheslav Ivchenko, who looked puzzled, Chen Geng thought for a while and asked Vyacheslav Ivchenko: "Mr. Ivchenko, how much do you know about the CF34 engine of General Electric?"

For Vyacheslav Ivchenko, the chief designer of the Ivchenko Design Bureau, Chen Geng's question is not too pediatric, if it weren't for the fact that everyone has worked very happily in the past few years, he would have wondered if the other party was humiliating himself, and even now, he was a little depressed: Although I am an aircraft engine designer in the Soviet Union, it doesn't mean that I don't know anything about the situation on the side of the old rival of the Soviet Union, right?

However, although a little depressed, Vyacheslav Ivchenko still answered Chen Geng's question: "The CF34 engine is a civilian large-bypass ratio turbofan engine improved by the General Electric Company of the United States on the basis of the TF34 military turbofan engine, as for the TF-34, in addition to the A-10 attack aircraft of the US Air Force in use, the US Navy's S-3 series of carrier-based anti-submarine, reconnaissance and tanker aircraft are also used in this series of engines...... Any questions, Mr. Fernández?"

This last rhetorical question undoubtedly represents Vyacheslav Ivchenko's dissatisfaction.

Chen Geng didn't care about Vyacheslav Ivchenko's dissatisfaction, who would make the family have the ability? He said with a smile: "What you said is right, then do you know that after General Electric has made a lot of money from the US government and the military by relying on the TF34, it is now ready to use the civilian model CF34 to make another wave of money in the field of larger civilian engines?"

“......”

Vyacheslav Ivchenko blinked and did not speak.

He didn't speak because he didn't know what to say, he knew that GE had made a civilian version of CF34 on the basis of TF34, but that was the end of it, as for how GE was going to use this and how much it could sell...... To tell the truth, is this something that I, as the chief designer of the Soviet Ivchenko Design Bureau, should care about?

"GE has partnered with Canadian regional aircraft manufacturer Bombardier to use the CF34-3A as the sole power system for Bombardier's first 50-seat regional jet aircraft, the CRJ-100, and according to Bombardier's plan, if the CRJ-100 market performs well, they will also develop regional jets with seats and even 80 seats. In addition to Bombardier Canada, Embraer is also looking to enter the regional jet segment......"

Looking at Vyacheslav Ivchenko, Chen Geng said: "Now, do you understand why I want an aero engine with the same thrust as the CF34?"
