Chapter 246 (1/2)

With the completion of the 5000 hour test run and the start of the final full-life test run, Wang Bin basically stays at the aviation laboratory every day and carries out the full-life test run with Professor Zhang and others. Of course, this can also be called destructive test run.

With the test run, the performance of ten engines was exceptionally good at 5500 hours, 6000 hours and 6500 hours, and there was no situation.

When the test run time reaches 7000 hours, the fuel consumption of one of the ten engines begins to increase. When it reaches 7200 hours, the fuel consumption of the ten engines on the test bench basically begins to become a little higher, but the sound of the engine is still good.

However, when the test run time reached 7600 hours, the fuel consumption of the engine on the No. 3 test bench became abnormally high. At this time, both professor poke and Wang Bin knew clearly that the service life of the engine had come to an end. At the same time, the situation of escaping from the engine was not so good.

Sure enough, when the test run time of the engine reached 7700 hours, the fuel consumption of all engines increased sharply. Even when the No. 3 engine was running, there was a slight vibration and a trace of abnormal noise.

Finally, when the test run lasted 7800 hours, Professor Zhang finally gave the order to stop the test run, because at this time, the fuel consumption of the misbehaving engines on the ten test stands had increased sharply, and the engine vibrated and made abnormal noise.

So to this extent, the test run is no longer necessary, because both Professor Zhang and Wang Bin know that the internal situation of the engine must be very bad at this time. If the test run is ongoing, unnecessary accidents are likely to occur.

When all the engines on the test bench stopped, the whole test shop suddenly became quiet, and everyone in the test shop suddenly became silent, because no matter Professor Zhang, Wang Bin, or others in the test shop, even those who don't know the operation time limit of the aeroengine, The significance behind 7800 hours of full life test run, especially for Huaxia.

You know, if such data were put a few years ago, even the best engine in China could not reach this data in all its life, that is, from the beginning of a new engine to three major overhauls and then to scrapping. Therefore, this test run data is definitely very powerful.

About ten minutes later, the young people in the test shop suddenly remembered the fierce cheers. At the same time, their hearts, including Wang Bin and Professor Cha, felt extremely proud because their engine had a long service life and created a miracle.

Of course, like these young people, Wang Bin was very excited, and praised Professor Zhang and everyone present on the spot. At the same time, he suddenly sent a large number of red envelopes in the aviation laboratory group to celebrate. Finally, he announced that the salary of everyone in the aviation laboratory would double from this month.

You know, this is an aviation experiment! As technicians in aerospace, their wages are several times higher than those of others in Tiangong technology, and now they have doubled on the original basis. How can this make them unhappy!

So when Wang Bin announced the news, all of a sudden, the people in the laboratory were more excited.

It was not until everyone's mood calmed down that Wang Bin and the technicians in the laboratory dismantled all the ten engines on the test bench and sent them to the assembly workshop to prepare for the disassembly of the ten engines one by one.
