As soon as the two of them finished talking about this, the ground bench was also ready, and the engineer came over to ask if the test could start, Wang Dazhi naturally nodded, and warmly invited Director Feng to press the button that symbolized the start - why else why did you invite Director Feng to run this trip today?

And Director Feng is naturally as good as a stream.

The starting procedure of a high-thrust aero engine is somewhat complicated, if it is an aircraft, it is necessary to start the APU first, and the APU will start the engine (in addition to starting the engine, the APU is also responsible for the aircraft when the aircraft is parked on the ground, and the air conditioning system when the engine is not started, The lighting system, the instrumentation system of the cab and the detection system of the whole aircraft provide the power that can work normally), and normally, the output power of an aircraft's APU system is around 100 kilowatts, so the starting procedure of the aircraft is probably a small starter motor to start the APU with a maximum power of hundreds of kilowatts, and then the APU starts the engine.

At this moment, the starting procedure is similar, but at this moment, the starter responsible for starting the engine has been started and running, with Director Feng pressing the start button, the starter began to run, and slowly started the military version of the RB211 engine to the slow state, after running slowly in the slow state for a period of time, the engine's fuel injection system began to supply oil, accompanied by a burst of smoke, the engine started smoothly......

The scene immediately burst into warm applause, although everyone knows that this engine will be able to start smoothly, after all, COMAC is too familiar with the RB211 engine, but when the engine is started smoothly, everyone is still very excited.

Director Feng was even more excited, he happily patted Wang Dazhi's arm and said loudly: "Okay! Comrade Wang Dazhi, your COMAC Group has made meritorious contributions to the country, and with this engine, I have more confidence in our country's large transport aircraft." ”

"Hey, hey, hey......"

Wang Dazhi, who was also excited, only scratched his head and smiled happily at this time.

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

It's just the first test run of this military version of the RB211 engine, according to normal test standards, as long as the engine can be ignited smoothly and the speed can reach 80% of the maximum speed, even if the entire test work is completed, as for the full speed operation, it is simply impossible.

But no one felt sorry, even Director Feng, he already knew today's test subjects before he came, so when he saw that the speed of the engine had reached 80% of the design speed, he couldn't stop smiling, and while repeatedly encouraging Wang Dazhi, he also repeatedly told Wang Dazhi to guard against arrogance and rashness, and strictly do a good job in the test of this engine...... Huaxia's future large transport aircraft will rely on this engine to live.

Comrade Wang Dazhi naturally nodded again and again, saying that we will definitely provide qualified aero engines for the country......

The day after sending Director Feng away, Wang Dazhi rushed to a certain aviation division of our army equipped with the Il-76 transport plane non-stop.

Although the core equipment of the aviation division is more than 10 Il-76 transport planes purchased from the former Soviet Union, the aviation division is very interested in the Z-9 helicopter produced by the COMAC Group, a certain armed helicopter that was previously shielded because of the number, and the American CH-54 "Tach" that has just been equipped not long ago. The heavy helicopters with heavy helicopters as the reference object are very well understood, so the leaders of the aviation division are very welcome to Wang Dazhi's arrival, and the division commander and political commissar are not good to leave the camp directly, and directly arrange for a deputy political commissar Qin who had been a little hypocritical with Wang Dazhi to go to the airport to pick up Wang Dazhi's plane.

Deputy Political Commissar Qin had worked in the general assembly before, and Wang Dazhi was already very familiar with him, after receiving Wang Dazhi, he smiled and joked with Wang Dazhi: "My Mr. Wang, I didn't say you, your company has its own airport, we also have an airport, I heard that your group has regulations, leaders can use business jets when traveling, right? How good are you to use business jets, starting from your company's airport, coming directly to our airport, how trouble-free?"

"Then let you inspect our plane for a month to see if there is any spy equipment on my plane?" Wang Dazhi hehe: "I'm not that stupid. ”

Not only sensitive, Wang Dazhi felt that this was too arrogant and rampant, and after working for most of his life, one thing Wang Dazhi knew most in his heart was that life can be proud at any time, but it should not be rampant.

It's like if I came to visit the leader of the aviation division this time, isn't it the same as taking the first class cabin of a civil flight, and it's not eye-catching.

Deputy Political Commissar Qin laughed.

After laughing, Deputy Political Commissar Qin asked Wang Dazhi: "Old Wang, you can always give me an account now, what are you coming to our division for this time?"

Wang Dazhi did not answer immediately, but asked Deputy Political Commissar Qin: "Old Qin, I heard that the engines of the Il-76 transport planes in your division, which were delivered relatively early, are about to be overhauled?"

As soon as he talked about this, Deputy Political Commissar Qin's face immediately lost a smile, and he frowned and said: "Yes, you also know that our country has only a few large jet transport planes, which are also needed here and there. ”

Speaking of this, Deputy Political Commissar Qin seemed to have just reacted, and asked Wang Dazhi in surprise: "What? Lao Wang, do you want to take on this job? I won't hide it from you, you also know that our air force has its own engine repair shop, and they are already eyeing this job." ”

"As for me going to rob them with them, it's not enough to lose people's money," Wang Dazhi waved his hand again and again, and said to Deputy Political Commissar Qin: "I came here this time, one is to see an old friend, and the other is to discuss with our unit about changing the issue of the Il-76." ”

"Change the hair of the Il-76?" Deputy Political Commissar Qin was stunned: "What kind of hair?"

"Of course, the aero engine produced by our COMAC Group," Wang Dazhi said confidently with a natural look: "A D-30KP-2 engine of our group is at the same thrust level as the D-30KP-2 engine carried on the Il-76 transport aircraft, but the engine with a larger thrust-to-weight ratio, lower fuel consumption and lighter weight has passed the national acceptance and obtained the type certificate and production license.
