Take Off My Aviation Era

However, whether it is the well-regulated "headquarters building" project of the superior unit, or the ZBDL aerial platform that Zhuang Jianye intended, this immediate five-year big project has clearly boosted China's take-off and the local economy.

Needless to say, in order to support the ZBDL aerial platform, 4 thermal power stations with an installed capacity of 200 MW and 6 supporting power stations with an installed capacity of 50 MW have been planned locally.

In this way, the power demand problem of the key project of ZBDL aerial platform was used to solve the problem of power shortage since the founding of the Qinling Mountains in one fell swoop.

With the large-scale construction of power, the most important infrastructure, almost all areas are driven, such as mineral development. How can you build large-scale thermal power plants without energy? So coal in the southern foot of the Qinling Mountains Energy industries such as natural gas and natural gas immediately ushered in great development.

With the power station, it naturally needs to be transported out, right?

Therefore, the supporting transmission and transformation lines also need to be built on a large scale.

With power stations and energy, the two need to be connected, right?

Therefore, the pipeline transportation of natural gas, and the railway and road transportation of coal have been put on the agenda.

The construction of power stations requires construction machinery, and power generation requires key equipment such as industrial gas turbines, right?

As a result, China Ascendas' subordinate engineering machinery and industrial gas turbines have experienced explosive growth.

Especially in the field of industrial gas turbines, these high-power core equipment are not only needed for power stations. ZBDL high-altitude platforms also need these high-power core equipment, such as the gas supply system of the simulation experiment cabin at the core of the high-altitude platform. This is the key equipment for simulating the high-altitude environment. Composed of 24 high-power centrifugal compressors, it can provide an air flow rate of more than 1000 kilograms per second in a very short period of time with a maximum pressure of 8 standard atmospheres at the same time.

For this reason, China Ascendas has equipped 24 high-power centrifugal compressors with 12 6 MW D-33 gas turbines, so that the entire supply system can quickly, effectively and continuously provide the required test environment.

In addition to the air supply system, there is also a heating and cooling system in the high-altitude platform experiment cabin, so as to better simulate the thermal phenomenon when the high-speed airflow impacts the engine and the low-temperature environment above the very high altitude.

Therefore, rapid heating and cooling is essential.

Needless to say, heating is necessary to heat the airflow of 1000 kilograms per second to 500 degrees Celsius. An improved cupola is needed. The core devices are two 10-megawatt D-47 gas turbines developed by China.

The natural gas consumed for one day of operation is equivalent to the one day consumption of a medium-sized city of 500,000 households.

This is already amazing, but compared to refrigeration, heating can almost be on the top of the list of energy saving and emission reduction, because the air flow of 850 kilograms per second needs to be quickly reduced to minus 70 degrees Celsius, which is basically done by ordinary gas turbines. No, it needs a special large expansion turbine to do it.

And this technology is only available in the US General Company and Russia's Gas Power Design Bureau, and the sensitive equipment catalogs that have been forbidden to export by the two countries can not be bought at all.

If you can't buy it, you can build it yourself. So it took China three years to take off, finally conquering the key technology of large expansion turbines and realizing the complete localization of high-altitude fast refrigeration equipment.

But at the same time, this set of equipment is also a veritable electric tiger. It can consume 9 megawatts of electricity in one day of operation, and its cooling capacity is enough for a city with a million people to be air-conditioned all summer.

And this is still part of the core equipment of the entire aerial platform. If you want the entire aerial platform to operate completely and all kinds of electrical equipment are fully turned on, the daily consumption will reach an astonishing 32 MW, which is equivalent to a large area with a population of 5 million. The electricity consumption of the city in a day.

And this is why China Ascendas selected the ZBDL high-altitude station at the southern foot of the Qinling Mountains, which is close to the aerospace production and manufacturing base, rather than in places such as Xingzhou or Cotton, which are more closely related to aviation business.

Because the coal and natural gas resources in the southern foot of the Qinling Mountains are more abundant, and the power infrastructure itself is also very complete, there is not much power consumption industry in Shanghai, and the power transmission is not smooth, so all these can just become the electric tiger of the ZBDL high-altitude station. Place of blood supply.

If it is placed next to cities such as Xingzhou, it is estimated to be in big trouble. As long as the ZBDL high-altitude platform is tested and the firepower is fully opened, the large cities of Xingzhou must be cut off, otherwise it will not be enough for ZBDL high altitude. Taiwan consumes.

But even if the southern foot of the Qinling Mountains is uniquely located, new power plants need to be built to support emergency power supply. Otherwise, if the ZBDL high-altitude platform collides with the local power grid peak, parts of Gansu and Ningxia provinces in the northern foot of the Qinling Mountains Will also encounter the treatment of power cuts.

Therefore, in order to solve these gaps, several more power plants have to be built to balance industrial production and residents' lives.

But no matter how huge the consumption of ZBDL high-altitude platform is, the effect after completion is obvious. The most direct effect is that China Ascendas discovered that the runoff changes of the 2nd generation core machine and 2.5 generation core machine developed before will cause some models in the high-altitude environment. The engine appeared to be surging, so it was immediately modified, the structure of the two core machines was re-optimized, and the layout of some models was adjusted to solve this problem.

Then there are a series of test results around WD-variable cycle aero-engine.

If this were put in the past, even if China Ascendas made a WD-variable cycle aero engine, it would not dare to put it on the plane, let alone show it in front of many heads and leaders.

Because this type of engine is just like a two-faced hypocrite, it looks like a mid-low altitude, and it's another at ten thousand meters altitude.

After all, the high-altitude performance of this dual-flow engine that can achieve supersonic cruise is really difficult to control, especially the coordinated speed of the first-stage fan and the second-stage fan combined with the compressor behind, and the closing and opening of the duct baffle Timing can’t be solved with a few formulas ~www.readwn.com~ and a few theories.

It is a talk of experience that requires thousands of hours of continuous experimentation and accumulation to gradually explore.

If there is no ZBDL high-altitude platform, just relying on China's Ascendas' Yun-19NB large-scale aero engine experimental verification platform, it will have to do 10,000 more times, and it will not be clear about the operating mechanism of the WD-variable cycle aero-engine at supersonic speed.

No way, although the performance of the Yun-19NB large-scale aero engine has nothing to say, but the maximum speed is only 0.83 Mach, and it can't fly in the supersonic range even if the milk is used. How do you do the supersonic cruise test?

Therefore, the significance of ZBDL high-altitude platform to China's take-off is not only the achievement of a high-level aero engine, but more importantly, it has further established China's unshakable dominance in the domestic aviation industry and used it as a springboard. , Straighten your body, point your sword at the world, and attack the three giants with absolute aviation hegemony, including Rolls-Royce, Pratt & Whitney and GM, until they establish their own aviation hegemony.

Because of this, ZBDL high-altitude station and China take off, it is the foundation of the future global aviation hegemony!
