694 Director Liu, who has never driven a helicopter, can guide the super pilot (for the South Gate Tiger
Liao Zhuojing's words made Liu Yijiu feel heartbroken for no reason.┝.』』.c［o
If there is no equipment, as long as people are there, they can be remanufactured. If there is no people, what is the use of these equipment? The reason why Liu Yijiu couldn't go down is not to show that he was not afraid of death. He knew that under any circumstances, Li Rui would try his best to keep his safety. Li Rui put on and landed on was also for him.
So, he didn't say anything.
But he hopes to take Huang Pingyang to dance together, if he can't control it.
Huang Pingyang is a super-class pilot who is piled up with gold. Nowadays, among the Republic helicopter pilots, there are very few super-class helicopter pilots, especially those who have been in the comprehensive test flight of the Z-8. He also flew such a long time in the Z-91. No one in China can compare with his experience.
He was the one who was the one who was the one who had only one prototype since the beginning. The test pilots of the next few aircraft were all selected from other troops and were not the most top helicopter pilots.
"Old Huang, don't lift the pitch, keep the helicopter flying smoothly, don't lift the pitch, keep the flight smoothly! If the output power of the motor is increased, the remaining motivation will stop due to overload..." Liu Yijiu had no choice but to arrange a few security personnel to prepare. Once the aircraft completely lost control, he had to hold Liao Zhuojing and Zhan Like and jump down.
Fortunately, when I returned to the middle passage of the cabin in front of the cabin, I saw Huang Pingyang, sweating profusely lifting the pitch, hoping to increase the output power of the remaining helicopter motor that did not stop working.
I was shocked immediately.
In such a scenario, continuing to increase the output power of the motivation will likely overload the motivation and then stop.
Once such a situation occurs, there will be no chance.
When Huang Pingyang heard this, his nervous mood suddenly became relaxed. He no longer cared about whether the motivation was sufficient, but tried hard to control the helicopter's posture of maintaining a stable flight. ┞k═┝═╞.《. In this way, the helicopter's descent was effectively controlled.
"Director Liu, control it!" Although the helicopter was still descending rapidly, it was not uncontrollable.
"Don't worry. I have confidence in my design and my operation, too. Try to keep the flight posture stable and find an open space to land. Before landing, we are still very dangerous." Although it is designed that even if a single motive stops, the helicopter can fly very far away and even fly back to the airport without overload weight, however, this is a plateau, and anything can happen.
At a height of 6,000 meters, the air flow is not too strong, but on the hills on the ground, the wind is very strong.
In the case of a motivation, the output power is insufficient. It is not easy to control the flying posture. It is even likely that the strong wind will be blown over directly! The end of the plane is destroyed and the people are killed.
The Republic also introduced the meter series helicopters and French helicopters. In the end, none of these helicopters were deployed on the Qinghai-Tibet Plateau because these helicopters were not very stable under harsh, complex and changeable meteorological conditions.
Not to mention anything else, even Mi-24 cannot reach the Qinghai-Tibet Plateau.
For a long time, only the United States exported the helicopters to China's civilian version of Black Hawks to the plateau. Even many border posts provided supplies, only enough reserves were reserved before heavy snow closed the mountain.
The helicopter did not descend as quickly as before, but slowly descended with a 30-degree trajectory flying forward. Even so, it made Liu Yijiu's nervous heart unable to relax, and Huang Pingyang was the same. From a motive to the present, in less than seven minutes, the helicopter fell directly from an altitude of more than 6,000 meters to an altitude of less than 2,000 meters!
On average, the helicopter fell ten meters per second!
Once the remaining motivation stops, the consequences are absolutely unimaginable.
Zhi-91, without a weapon system installed, the air weight is 72oo kilograms, which is 2.4 tons heavier than the Black Eagle of the United States. This is because a large number of titanium alloys are used to make the air so lighter. More than ten researchers, two drivers, and monitoring equipment weighing more than two hundred kilograms, combined with a weight of nearly ten tons.
Ten tons of objects move freely from a height of 6,000 meters...
"Continue to keep it up, don't think about increasing the pitch and increasing the output power of the motor, and find a place to make a forced landing. Pay attention to the hill ahead. If you can't fly over, take a detour!" Liu Yijiu has now become Huang Pingyang's navigator. These hills cannot be forced landing directly.
The other four helicopters were also accompanied by the flight.
"You don't have to worry that we can't stand it. We are not at the same level as if we need to use oxygen. Jump! We are not afraid..." He said he was not afraid. After jumping from such a high altitude, both Zhanliko and Liao Zhuojing were trembling.
When they were tested by Z-7, they had never been on the helicopter.
This time, Liu Yijiu did not ask them to fly randomly, but observed with a telescope below. They saw deep contempt in the eyes of the young Director Liu.
Before, they had never been on these helicopters they designed themselves.
"No need to argue, you don't have to jump off the plane now! Don't you feel that the plane is flying very smoothly now?" At the altitude of the Qinghai-Tibet Plateau, no one noticed that the plane's descent had become very slow.
The original devices used to monitor data during flight are still in operation, but no one is paying attention to the data.
There is a very clear answer in their minds whether to save lives or equipment. Therefore, as long as you say before, letting you jump without a parachute, they will open the hatch door without hesitation, let alone the parachute.
"Sure enough! The descent is 4.5 meters per second, and the flat freight is 155 kilometers per hour..." Liao Zhuojing heard Li Rui's words and hurriedly rushed towards the monitor next to him.
Liu Yijiu didn't pay attention to the future, and now it's a bit of a motivation.
The total power of the two turboshaft-4 motors is 286k, and the power of a single machine is only 143o. Although the power is greater than that of the t-7oo-ge-7o produced by General Electric, the thrust-weight ratio is much smaller than the thrust-weight ratio of the 7o1 motor used by Blackhawk, and only O.832.
Moreover, the turboshaft-4 motivation is a brand new motivation, which was created by Director Liu's gold finger. Without a long and large-scale flight test, whether it is as reliable and durable as General Electric's motivation, it is not enough to rely on the motivation to study for a long time and large-scale experiment!
Therefore, Liu Yijiu was still worried that the remaining motive would be shut down.
The height here is not high, and once it falls, it will basically be completely ruined.
"Director Liu, thanks to you! Huh..." Huang Pingyang let out a long sigh after the plane successfully landed.
Until now, he had the heart to apply beads of sweat the size of beans on his forehead.
In this case, he was really scared.
Also, the plane did not fall and the equipment behind it was not dropped.
"Xiao Liu, when will you drive a helicopter?" When Liao Zhuojing stopped the plane, he was weak with his legs and almost collapsed on the chair. After hearing that it was Liu Yijiu's good command, he couldn't help but feel a little surprised.
Director Liu can always bring them such an incredible feeling of surprise.
Liu Yijiu smiled bitterly, "It's not that I can drive a helicopter, but that I know how to operate it in theory. As a chief designer of a helicopter, you have to remember all kinds of structures and operations. In that case, the power of a single motive is a bit bare and the power output is a bit insufficient, but the lift generated will not completely lose control. In a flat flight state, the command will form an angle with the ground to drop evenly..."
For the helicopter of the Zhi-91, Liu Yijiu, which took too much effort, every place and every system, he was familiar with it.
He has a brain that is not inferior to that of computers.
"It's true that's all!" Zhan Like was responsible for the production aspect and was not familiar with these, but he turned out to be the deputy chief designer of Zhi-7, and he was also unfamiliar with these technical issues.
"Okay, let's take a break and prepare to find the problem. In this case, if we can't handle it as soon as possible, we have to spend the night on this snow-capped mountain." Liu Yijiu didn't want to talk about this matter again. In this case, even the chief designer may not be able to know how to deal with it or how to deal with it.
I have never eaten pork, at least I have seen pigs run away.
The experience accumulated over the entire national military industry system for a hundred years is definitely not for nothing.
"Director Liu, let's fly the plane slowly to the temporary base. The car on the mountain here cannot come..." Huang Pingyang asked for his order.
"No, there are tools in the other helicopters..." Liu Yijiu shook his head and refused.
The problem here shouldn't be very big.
At the beginning, he looked at all the electronic instruments on the console. Although the indicator lights flashed constantly, they were all caused by insufficient output power of the motor.
He had already guessed the reason for the motivation to stop, but he didn't say it out.
On this cold plateau, Liu Yijiu and Liao Zhuojing and others personally inspected the entire helicopter. Liu Yijiu did not check it side by side, but directly opened the motive cabin on the top of the helicopter and finally inspected the compressor carefully.
"As expected, it was caused by the compressor failure!" Liu Yijiu looked at the compressor and said with a wry smile.
No one else thought that Liu Yijiu would have a problem so soon... (To be continued.)
ps: Sorry, Tiger, I should have added updates for the Big Big for a long time, and it has been delayed until now.
