Chapter 593

Compared with the hot eyes of the army leaders, the head of the headquarters was not so excited. Instead, he overcame his face and exchanged something with the airborne Army leaders and other officers.

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

"why does the headquarters have no project approval notice?" "Why didn't you write down such an important matter as airborne soldiers in the report?" "Don't always use Tengfei group as an excuse. Their R & D progress is fast, and you should keep up with it in time..."

After listening to Hou Yuejin's cold sweat on his back again, he said that he would not cause trouble for the group. It's just a wd-30s turbofan engine with water testing properties. How can it cause such a big problem?

That's what Hou Yuejin thought in his mind. If he said it, it would absolutely drive all the big guys, including the head of the headquarters, crazy. It's just a test of water. Why don't you take off group go to heaven?

However, Hou Yuejin really didn't regard wd-30s turbofan engine as a crucial core equipment, because compared with the aviation power turbofan plan launched by Tengfei group in late 1990, wd-30s turbofan engine is really a test product.

Otherwise, how can it become the power of the attack-2 UAV? It has long been used on the advanced light transport platform that has begun to verify the static test of the UAV.

After all, the technical basis of wd-30s turbofan engine is the D-30 series gas turbine power plant which is more mature in Tengfei aviation power. The most famous derivative of this model is the d-30ml turboprop engine which replaces Honeywell engine and is installed on Yun 6.

Of course, in today's numbering reform, a W has to be added in front of the d-30ml turboprop engine to become a wd-30ml turboprop engine.

Another important derivative of the D-30 series gas turbine power plant is the d-30z series turboshaft engine, which was originally used as the backup power for the light helicopter project, but in the end, Tengfei group became one of the top two manufacturers in China.

Due to the balance of the industrial structure, the power of the turboshaft is biased towards the manufacturer of turboshaft 8. Therefore, although the d-30z series turboshaft engine is listed in the list of key research and development, it is accompanied throughout the whole process. It is impossible to say how much attention it is, but it is impossible to say how much attention it is.

Therefore, Tengfei group takes the d-30z series turboshaft engine as the test power of the improved zhi-6 helicopter led by Professor Zhao.

You know, when the improved zhi-6 helicopter first came out, it was not as aggressive as it is now. It brought a lot of shadow of the old zhi-6.

Moreover, since the power of d-30z series turboshaft engines is only over 500 kW, three d-30z series turboshaft engines were used in the first few prototypes.

This is mainly because the single power of d-30z series turboshaft engine is only one-third of that of the original turboshaft 5 used in zhi-6. You should know that the turboshaft 5 developed in the mid-1970s has reached the value of 1600 kW.

Of course, the defects are also obvious, that is, low life, poor maintenance, and the overall performance is not up to the standard. Because of this, we got off the horse together with zhi-6, which also has similar problems.

If this is the case of Tengfei group, it will try its best to perfect and improve the engine even if it gets off the horse. After all, the engine is not built overnight. Instead, it needs to gradually accumulate experience and improve the performance a little bit, rather than slapping the head on a model, which can be used in a few years.

Even the United States, the leader of the aviation development industry, had a big fall in this field at the beginning. However, people saw that a model was constantly improved and improved. Finally, starting from the j57, it became an immortal legend generation after generation.

People only see the dominant position of Americans in the aviation industry, but who can realize the nearly 20 years of silent suffering and patience of American aviation engineers before the maturity of j57?

In this respect, China is far from a powerful country in aviation development. The technical problem is on the one hand, and the most important problem is the concept, because everything in China is fast, fast on, fast on, fast equipment.

Time is money and efficiency is life.

This may be true in other industries, but in the industry of aeroengine, which needs high investment, long cycle and slow return, it's really overcorrected. There's no way. There's really no shortcut for this industry. It's only one step at a time to complete all the processes of the developed countries' aviation development, that's to say, the Long March can be completed. At most, it's able to take out a chance Axis-8 is the same level of spare parts, and we don't know whether the maturity can stand the test.

As for turbofans, the industry doesn't expect Tengfei group to make any achievements at all. It doesn't think it's necessary for Tengfei group to go in this direction. Now that it's recognized by the industry, it's OK to produce turbofans safely and steadily. High end products like turbofans should be handed over to other domestic manufacturers.

It is not only the vigilance of the same type of production enterprises to take off factories, but also the protection of the industrial structure and key factories by the superior departments, and the guidance of the national industrial policy.

Anyway, the turbofan engine of Tengfei group has not been supported by the industry.In addition, for so many years, Tengfei group has only been working around the D series to light up the turbine power to repair, which makes the original leaders who are optimistic about Tengfei group lose patience. After all, the leaders are optimistic about their political achievements, and they are always immersed in a series, either repairing or repairing. For several years, there has not been a new type of project, which is a pile of repaired sub models Where do you get your achievements?

So from 1988 on, let alone in the market, there was little news about the new aeroengine of Tengfei group in the industry. Coupled with the deliberate guidance of other aeroengine manufacturers, the relevant partners including the military felt that Tengfei group was a professional manufacturer of turboprop power and some auxiliary power equipment.

This is why many heads of the headquarters are surprised at the moment when they see the wd-30s turbofan engine, and they call several officers aside to ask questions.

Tengfei group is actually able to produce turbofan engines, and it is also a small turbofan engine urgently needed by the army. Why does the report always show that Tengfei group is only a turboprop engine manufacturer?

Hou Yuejin is just nervous, not a fool. What's more, he has worked under Zhuang Jianye and Lin Guanghua for so many years, and his mind has been opened by them for a long time. So when he thinks about it carefully, his heart suddenly nods. When he is neutral in his mind, Zhuang Jianye's brilliant smile appears.

He exclaimed: "is this the calculation of general manager Zhuang? Push left and push again, no one answers, just a pole to pierce the sky? "
