Chapter 1500 A sudden turn of events
Just as Cheng Junhong was hesitating at the door of Yang Wei's office with the report in hand, the door in front of her suddenly opened.
Yang Wei put on his suit jacket and walked out.
After seeing Cheng Junhong blocking the door, he subconsciously took two steps back and looked the latter up and down, obviously feeling a little surprised.
"Old Cheng? I was just about to look for you." After coming to his senses, Yang Wei quickly stepped forward and said, "I just called your office and cell phone more than a dozen times, but no one answered..."
Thanks to his legendary experience of going directly to university after graduating from junior high school and his subsequent smooth promotion path, his age is actually similar to that of many of his subordinates, so calling him "Xiao Cheng" is obviously not appropriate.
Cheng Junhong then remembered that she forgot to turn on her cell phone after getting off the plane, and quickly explained: "Sorry, Mr. Yang, I just flew back to Chengdu, so my phone should be turned off..."
"Let's not talk about this for now." Yang Wei interrupted him, and walked to the other end of the corridor while motioning to follow him, "It's just right that you're back today, hurry up and follow me to the meeting room!"
This sudden change made Cheng Junhong freeze in place for a moment:
"I……"
He raised the document in his hand and gestured to Yang Wei.
But the latter had already walked some distance away and did not notice what was happening behind him.
At this point, Cheng Junhong could no longer insist and had to quickly catch up with Yang Wei's pace. She was somewhat curious about what kind of meeting could make the other party so anxious.
Then, I naturally thought of the business jet on the tarmac. :
"Boss Yang, is this... a higher-up coming to inspect?"
Yang Wei shook his head: "Yes, he is a leader, but it can't be considered an inspection."
As if he saw Cheng Junhong's puzzled expression, he immediately added:
"Academician Chang Haonan from the Aviation Power Group came with his team and said they wanted to discuss an important cooperation... I originally thought that since you were staying in Yanliang, I would just forget about it, but when I heard that you were coming back this morning, I temporarily added your name to the meeting list..."
For Cheng Junhong, the things that come later are not the key points. The key lies in the name mentioned at the very beginning.
"Academician Chang?"
His footsteps faltered:
"Could it be the one who worked on the waverider..."
The reason why Plan B of Wuzhen 8 can use an aerodynamic design with waverider elements at such a low cost is largely because it stands on the shoulders of the opponent.
"That's him! Don't ask anymore, the meeting will start soon." At this time, Yang Wei finally saw the document in his hand clearly, "Progress report of Plan B?"
Cheng Junhong nodded: "The situation is not too..."
Before he could even utter the word "optimistic", he was interrupted by the hurried Yang Wei:
"I don't have time to read it. You can take it with you and give it to me after the meeting."
He had no choice but to stuff the report into his briefcase and quickly followed the other party to the meeting room, but his mind was still on the report that was about to declare the project a failure.
In fact, Cheng Junhong was completely unprepared for the sudden meeting, and he couldn't think of anything to do at the last minute. He could only wait until the meeting started and then act accordingly.
It was not until an assistant behind him gently pushed him that he realized he was standing at the door of the conference room and almost bumped into Yang Wei who was about to enter.
There were already more than a dozen people sitting in the small room, sitting on both sides of the long table.
Cheng Junhong recognized that several of them were the technical backbone of Chengfei Group, and the team opposite was obviously from Aviation Power Group.
In a formal meeting, it would definitely be inappropriate to keep guests waiting for so long, but Chang Haonan and Yang Wei are already old acquaintances and don't care about these details.
Cheng Junhong hurriedly found an empty seat and sat down. When she looked up, her eyes met with Chang Haonan who was sitting opposite her.
Although he already knew the other person's approximate age, the real person was younger than he had imagined, so it was difficult to associate such a face with a leading figure in the field of aviation power and aerodynamics.
Just as Cheng Junhong was about to nod politely, she caught a glimpse of two lines of words on the big screen in front of the conference room.
"Ramjet engine including a magnetohydrodynamic generator before the combustion chamber and a magnetohydrodynamic enhancer after the combustion chamber".
This lengthy title took Cheng Junhong a while to react to.
He blinked, read it again, and suddenly felt his heart beating violently.
"Magnetic fluid generator... or is it used in ramjet engines?"
An indescribable premonition came over me.
He might not know much about magnetofluids, nor did he know what a magnetofluid enhancer was, but the word "generator" clearly caught his eye.
In an instant, Cheng Junhong knew why Yang Wei asked her to come over.
At this time, Chang Haonan stood up and began to speak: "Thank you all for taking the time. Today we are going to discuss an innovative power supply technology, which is expected to solve the power supply bottleneck problem caused by the structure of the ramjet engine..."
Cheng Junhong listened attentively, and the pen in his hand unconsciously clenched.
Chang Haonan then explained the basic principle: an ionization enhancement module is set up in front of the ramjet engine combustion chamber to convert the normally insulating gas into a high-temperature and high-pressure conductive plasma, and then a potential difference is generated through the Faraday channel. Finally, the magnetohydrodynamic enhancer is used to reuse the energy to a certain extent and recover the ionization seeds.
It sounds very simple, but everyone here knows that in order to turn this short sentence from theory into reality, every word contains unimaginable difficulties and obstacles.
"This... isn't this exactly what we need?" Cheng Junhong almost blurted out.
Although the performance of this magnetohydrodynamic generator is still unknown, the power gap in Plan B is only 2-3kW.
Therefore, almost immediately after Chang Haonan finished introducing all the contents, he couldn't wait to raise his hand and ask:
"Academician Chang, this technology seems to be more suitable for hypersonic aircraft with a speed of Mach 5 or above... Is it effective for ramjet engines with a speed of around Mach 4?"
The conference room suddenly became quiet.
Cheng Junhong realized that it might not be the turn for someone of her level to speak yet, and suddenly felt a little embarrassed.
But Chang Haonan just smiled and said, "It's a good question. Indeed, this technology was originally designed for hypersonic aircraft. In the JF14 wind tunnel test, the highest power generation efficiency appeared roughly in the Mach number range of 7-8."
Cheng Junhong's heart sank, but the other party quickly changed the subject:
"However, we found that at a speed of around Mach 4.5, with the right ionized seeds, it is still possible to generate considerable power... In fact, the reason why we chose the Wuzhen 8B solution that you, Engineer Cheng, are responsible for as the test platform is precisely because of its high technical maturity and the current power supply problem is exactly what our solution can handle."
Cheng Junhong felt dizzy, as if fate was playing a joke on him.
A few hours ago, he was writing a report on the project's failure; now, the solution came to him.
Chang Haonan continued to explain: "According to our calculations, if we remove the two turbine generators and their air inlets on Plan B and rely entirely on the magnetohydrodynamic power generation system, we can not only provide about 10 kilowatts of steady-state power generation, but also reduce aerodynamic drag and increase the maximum speed to more than Mach 4.5."
Cheng Junhong could hardly believe her ears.
"10kw?"
For him, this number is enough.
"That's right, two engines in total." Chang Haonan nodded, "and the system weight is 30% lighter than the original turbine generator set... As for the power supply problem before accelerating to Mach 4, high-energy batteries can be used temporarily."
During the rest of the meeting, Cheng Junhong concentrated on recording every technical detail.
The data and test results presented by Chang Haonan's team were convincing, and Yang Wei also added from time to time the significance of this cooperation to Chengfei Group, while quietly giving a very high evaluation to Cheng Junhong.
Until the end of the meeting, Cheng Junhong was still immersed in the excitement of the technical discussion.
He had already begun to re-plan the direction of improvement for Plan B in his mind, and even thought about how to adjust the composite reconnaissance module to make full use of the extra power.
"Old Cheng." Yang Wei called him after the crowd dispersed, "What report did you want to show me before?"
Only then did Cheng Junhong remember the report in his briefcase that declared the project failure.
But in the current circumstances, its content is clearly no longer appropriate.
"No, it's nothing serious, Mr. Yang." He quickly changed his tone, "I will immediately organize a team and prepare to connect with Academician Chang to implement the technical improvement plan as soon as possible!"
