Chapter 576

When the "small forklift" helicopter flew to a steep hillside, its speed dropped down. Then it made some adjustments in the air to stabilize the helicopter itself and the steel structure components hoisted below, and began to descend. It slowly approached the construction workers and opened up a small platform just at the hillside.

The whole process can be described as one go, without half a drag.

Looking at this scene, the head of Lu Hang is just as attentive, serious and meticulous as seeing the wonderful film he has been looking forward to for a long time.

From time to time, I have to put down the telescope and rub my eyes for fear that I can't see clearly.

At this time, the hoisting steel cable on the "forklift" helicopter will steadily lower the steel structure under the winch rotation, and the workers in charge of the installation on the ground will start to adjust the orientation details of the structure when the steel structure is still a little far away from the tower base.

Soon, under the guidance of the ground personnel, the steel structure was firmly connected with the tower foundation, the welder took the welding gun to start at the place where welding was needed, the riveter fixed the huge rivets in the pre reserved fixing hole, and the erector began to twist the fastening bolts everywhere

In a word, the workers on the installation site performed their own duties. Soon the steel structure on the tower foundation was initially fixed, and then some workers climbed onto the steel frame and removed the hoisting cables.

Hovering in mid air all the time, the "small forklift" helicopter, which is used as lifting support for the workers below, immediately starts the winch, takes up the steel cable, and then quickly pulls it up. After making a detour in the mountains on the construction site, it speeds up and flies to a certain regiment of land aviation in Southwest China.

However, less than half an hour after the helicopter left, another "small forklift" helicopter, with brand-new steel structural parts, flew quickly.

The same is not afraid of the wind in the mountains; the same is a one-stop approach, descent, put components; the same installation is rapid, take-off circle, leave

In this cycle, almost every 20 to 30 minutes, another "small forklift" helicopter flew over, accurately completed the lifting and quickly left.

This time, not only the chief of land and air transport was dumbfounded, but also Bian Kai, a professional, was dumbfounded.

If one or two sorties are so stable, it means that there are indeed capable helicopter pilots in the take-off flight.

The problem is that in two or three hours, after flying nearly seven or eight sorties, each of them is as steady as the one carved in the same mold, so Bian Kai is shocked. Is it difficult for all the helicopter pilots to be trumps?

If that's the case, why don't troops with a domestic pilot roster know?

……

"If you're not wrong, the" forklift "helicopter should be equipped with a fly by wire control system, otherwise every plane can't be so accurate."

For Bian Kai's doubts, Yodel, who had been looking at all this in the village, made his judgment very clear. He immediately put down his telescope and gave a long breath: "the engine with good performance has also applied the telex control system."

Before his voice fell, Yodel frowned and said, "under normal circumstances, we should not be so conservative."

Yodel's wonder is not unreasonable. The overall structure of the "forklift" helicopter is very similar to the S-64 made in the United States and the aerial crane. It seems that it is closely following the world trend.

But in fact, the S-64 aerial crane was a product of the United States in the 1950s and 1960s. By the 1980s, it had been completely replaced by the more advanced "Chinook" helicopter. The retired S-64 aerial crane had been renovated and put into the world engineering construction market, which gave it the reputation of aerial crane.

In other words, the S-64 aerial crane is not an advanced technology, and it is not in line with the current trend of helicopter development.

If the technology used by the Chinese people is ordinary low-end goods, it's all right. However, from the actual effect, the power of the "small forklift" helicopter is not bad, and it has realized telex control. Under such good conditions, it's hard for Yodel to come up with anything that can't go up or down. It's incredible.

But this is that Yodel stood in the village and looked at it from a distance, without close-up exploration or even thinking about it. Otherwise, it would not be unthinkable, but he could not understand why the helicopter would look like this.

If it's advanced, some of its components are not. Silicon nitride bearings, gear, shaft and bearing integrated components are all used.

But if it's conservative, the design and structure from the 1960s and 1970s can be found everywhere.

In a word, the "forklift" helicopter is a freak that combines advanced technology and conservative design.

The reason for this is very simple, the "small forklift" helicopter is not a brand-new model in the true sense, but an improved model of the old zhi6.

Because of this, "forklift" helicopter inherits many design and structure of the zhi-6, but makes a subversive improvement on the weak turbine shaft engine, main reducer components and flight control system of the zhi-6.Therefore, the "small forklift" helicopter is not so much a new model as the whole state of the straight 6 helicopter.

Because of the serious defects of the engine, main reducer and flight control, the accident occurred frequently during the flight test, which eventually led to the dismount.

Therefore, in the past many years, Professor Zhao has devoted all his energy to these three directions. Unfortunately, he has not found a suitable opportunity to realize them.

Until he went to Tengfei group and saw silicon nitride bearing, electron beam welding machine and fly by wire flight control of Flight Control Research Institute, Professor Zhao knew that his opportunity had come.

Of course, Professor Zhao didn't want to build a helicopter with better performance. After all, the manufacturing capacity of Tengfei group is there. In addition to the materials and aeroengine, as long as Professor Zhao's reasons are concerned, the index can be set higher.

However, Professor Zhao didn't do it. The reason is very simple. Helicopter is a system engineering just like other aircraft. It doesn't depend on which aspect of your ability you can produce.

Because of this, the system integration ability and the overall planning ability of design are very important. Just because Tengfei group lacks special talents in this aspect, Professor Zhao did not improve the development index, but helped Tengfei group cultivate a number of helicopter professionals from beginning to end with familiar old models.

Therefore, Zhuang Jianye thinks that compared with the quality of a helicopter model, the initially formed talent team for helicopter development and production is the most valuable.

Yodel naturally didn't know about this. As for Bian Kai, who was just like a curious baby holding on to Zhuang Jianye, he also didn't get a word from Zhuang Jianye, because a telex control system alone had already made Bian Kai not know what to say, which led to the following problems all around this aspect.

Look at Bian Kai's strength. I wish I could jump over and have a good experience of how a helicopter with electric transmission control system feels.

As a result, when Bian Kai was pestering Zhuang Jianye to experience, the chief of Lu hang, who had been observing carefully for a long time and had not said a word, suddenly sighed in a sad voice: "if only this plane had come out two years earlier Just come out two years earlier... "
