Compared with the fiery eyes of the leaders of the troops, the head of the headquarters was not so excited, but had a gloomy face, and whispered something to the head of the airborne troops and several other officers beside him.

Hou Yuejin could occasionally hear the head of the headquarters ask in a deep voice:

"Why didn't the headquarters notify the project?"; Why don't you Airborne Forces write down such an important matter in the report?"; Don't always use Tengfei Group as an excuse, their R&D progress is fast, and you must keep up with it in time......"

Hou Yuejin's back was in a cold sweat again, and he said that this will not cause trouble for the group, a WD-30S turbofan engine that tests the water, can it cause such a big problem?

This is what Hou Yuejin thought in his heart, if he said it, he would definitely make a lot of bigwigs, including the head of the headquarters, crazy, and test the waters, and that's it, why don't you Tengfei Group go to the sky?

However, Hou Yuejin really did not regard the WD-30S turbofan engine as a crucial core equipment, because compared with the aviation power turbofan program launched by Tengfei Group at the end of 1990, the WD-30S turbofan engine is really a product to test the waters.

Otherwise, how could it be the power of the Attack-2 UAV, which has long been used on an advanced light transport platform that has already begun to verify the static test of the aircraft.

After all, the technical basis of the WD-30S turbofan engine is the more mature D-30 series gas turbine power unit of Tengfei Aviation Power, and the most famous derivative of this model is the D-30ML turboprop engine that replaces the Honeywell engine and is replaced by the Yun-6.

Of course, in today's numbering reform, the D-30ML turboprop engine has to be preceded by a W to become the WD-30ML turboprop engine.

Another important derivative of the D-30 series gas turbine power unit is the D-30Z series turboshaft engine, which was originally used as a backup power for the light helicopter project, but in the end, the ministry and commission between the Tengfei Group in the turboprop engine and became one of the top manufacturers in China.

Due to the balance of the industrial structure, the turboshaft power is biased towards the turboshaft 8 production plant, so although the D-30Z series turboshaft engine is included in the list of research and development, it is the whole process.

Therefore, Tengfei Group used the D-30Z series turboshaft engine as the test verification power for the improved Z-6 helicopter led by Professor Zhao.

You must know that when the improved Z-6 helicopter first came out, it was not as domineering as it is now, and it brought a lot of shadows of the old Z-6.

And because the D-30Z series turboshaft engines only have a power of more than 500 kilowatts, three D-30Z series turboshaft engines were used on the first few prototypes.

This is mainly because the power of a single D-30Z series turboshaft engine is not one-third of the power of the turboshaft 5 originally used in the straight 6, and the turboshaft 5 developed in the mid-seventies has reached the value of 1600 kilowatts.

Of course, the defects are also obvious, that is, low life, poor maintenance, and the overall performance is not up to standard, and because of this, it was dismounted with the same similar problem of the straight 6.

After all, the engine is not achieved overnight, but it needs to slowly accumulate experience and improve the performance little by little, rather than patting the head on the last model, and you can come up with a usable engine in a few years.

Even the United States, the leader of the aviation development industry, also fell a lot in this field at the beginning, but people see a model of continuous improvement and improvement, and finally starting from J57, the achievement of generation after generation of immortal legends.

People only see the dominance of the Americans in the aviation development industry, but who understands the silent suffering and patience of American aeronautical engineers for nearly 20 years before the J57 matured?

In this regard, the domestic aviation development power is far behind, the technical problem is on the one hand, the most important thing is the concept of the problem, because everything in the country pays attention to a fast, fast, fast, fast equipment.

As the saying goes, time is money, efficiency is life.

This sentence may be correct in other industries, but in the aero engine industry, which requires high investment, long cycle, and slow return, it is really overkill, no way, there is really no shortcut in this line, only one step at a time, all the processes of developed countries in aviation development are completed, and it can be regarded as the first step to complete the long march.

However, the country does not believe in evil in this regard, and since the eighties, the model has been changed one after another, but none of them have been able to stick to the end.

It's all an assault, and it doesn't work, so I silently dismount, change the leader to sweep the achievements of the predecessor into the garbage heap, and re-erect the stove to continue.

It's no wonder that such repetition can produce results.

Ascendas has achieved results, but the ministry has divided Ascendas into small and medium-sized transport platforms and turboprop engine production plants according to the old-fashioned division of the aviation industry.

In other words, in the eyes of the aviation industry, Tengfei Group has been stamped and confirmed in the field of aviation development, and it is completely qualitative, that is, it specializes in the production of turboprop engines.

At most, you can come up with a spare item similar to the vortex-8 level, and I don't know if the maturity can stand the test.

As for the turbofan, the industry does not expect Tengfei Group to have any achievements, and it feels that Tengfei Group does not need to go in this regard, since it has been recognized by the industry, it is safe and stable to produce turboprops, and high-end goods such as turbofans are still handed over to other domestic aviation manufacturers.

It is better to say that this is the vigilance of the same type of production enterprises to take off the factory, to say that the higher departments can protect the industrial structure and key factories, and to say that it is the guidance of the national industrial policy.

Anyway, Tengfei Group's turbofan engine did not receive support from the whole industry.

In addition, Tengfei Group has been like a day for so many years, only around the D series to ignite the turbine power tinkering, constantly spinning, but also let the leaders who were originally optimistic about Tengfei Group lose patience, after all, the leaders are optimistic about the political performance, and they bury their heads in a series all day long, either repair or repair, there has not been a new model project for several years, it is all a bunch of tinkering sub-models, where do you let the leaders get political achievements?

So since 1988, not to mention the market, there is little news in the industry about the new aviation of Tengfei Group, coupled with the deliberate guidance of other aviation development plants, so that relevant partners, including the military, feel that Tengfei Group is a professional manufacturer of turboprop power and some auxiliary power units.

This is also the reason why many chiefs will be surprised when they see the WD-30S turbofan engine, and the head of the headquarters will call several officers aside to ask questions in a deep voice.

Tengfei Group can actually produce turbofan engines, and it is also a small turbofan engine urgently needed by the army, so why does the report always render Tengfei Group only a turboprop engine manufacturer?

Hou Yuejin was just nervous, not stupid, not to mention that he had worked under Zhuang Jianye and Lin Guanghua for so many years, and his mind had already been opened by the two of them, so after thinking about it so carefully, his heart suddenly chuckled, and Zhuang Jianye's hidden bright smile appeared in his mind.

I exclaimed in my heart: "Is this Zhuang Zong's calculation? Left push and push no one cares, so just stab the sky with a shot?"
