Half of the grand test bench workshop was still empty, and the floor was coated with epoxy resin, and the light almost shone on the figure.

The test bench is divided into two parts, one part is the engine test workshop, hundreds of square meters in size, the middle is the engine test bench, the test bench construction is very miscellaneous, a lot of sensors, monitors, cable lines need to be installed, and now the construction has been completed.

On the side of the test workshop, there is a thick transparent glass, which is the monitoring and operation room, where the aero engine is operated and tested, and the sound insulation design is adopted, and the thick glass can also play a good sound insulation effect, otherwise, the noise of the engine test will be unbearable for mortals.

A large number of instruments, display screens, operation screens, etc. will be installed in the monitoring and operation room to test, monitor and operate the test run of the engine.

This test bench workshop adopts a double-layer roof structure with noise reduction effect, which is very similar to Rolls-Royce's test bench, using a large number of concrete structures, and installing mufflers for intake and exhaust, and the investment in this test bench alone has reached more than 200 million.

In the name of producing small civil aircraft engines, Yonghan Aviation Power Technology Co., Ltd. also purchased the measurement and control equipment and software required for the test bench from the instrument and equipment companies purchased from the United Kingdom, Germany, France and Switzerland.

Liu Jianqing saw such an advanced test bench, and said to Yang Jie: "You haven't produced a single engine now, and you have directly set up a test workshop, I heard that you have also spent a lot of money in Yongzhou to build an experimental base, and you are building a high-altitude test bench, you kid is really willing to spend money." ”

Yonghan Aviation Power Technology Co., Ltd. has invested more than 500 million yuan to build an experimental base in the mountains of Yongzhou, and a test bench under construction is composed of two sets of experimental cabins, which are used for turbojet and turbofan engines to conduct high-altitude imitation experiments, and the thrust level covers all jet engines below 3000 kg.

This test bench can not only carry out high-altitude experiments at low temperature and low pressure, but also carry out special environmental experiments such as high temperature and long-lasting temperature.

The minimum temperature in the experimental cabin can reach minus 70 degrees Celsius and the maximum temperature can reach 200 degrees Celsius, which can imitate various airflow changes in the high altitude, test the extreme encounter ability of the engine, and collect the engine speed, temperature, pressure, fuel flow, vibration, thrust and other working data.

This is the design scheme of the experimental bench provided by 624, and the high-altitude platform designed by this institute itself comes from the same source as the high-altitude platform of Rolls-Royce, which was learned by Huaxia Guo in the process of cooperation with Rolls-Royce in the 80s.

"These platforms are too important for the research and development of aero engines, and now there are too few such experimental platforms in China, and I don't want to grab these experimental platforms from the military, so I have to build them myself." Yang Jie said with a smile.

"Compared with your Yonghan Aviation Power Technology Company, the military's investment in this area is still too small......"

Liu Jianqing couldn't help but sigh and said.

Yang Jie was silent.

After visiting the test workshop, Yang Jie also accompanied Liu Jianqing to the final assembly workshop.

The hardware facilities of the assembly workshop are all in place, the turbofan engine assembly bench has been installed, because the company's important goal is now 3000 kg below the turbofan engine, the engine volume is not large, the assembly bench is not small, the ten assembly benches are all completed, lined up, and the total pretending industry can be carried out at any time.

Before the final assembly of the engine, the assembly of each component needs to be carried out, and after the assembly of each component, the overall assembly of the engine is carried out on the assembly bench one by one, and the assembly work is also carried out in the assembly workshop, and the workshop is specially divided into a Hengshan turbofan engine parts assembly area.

The grand assembly workshop, the ground is spotless, this is a dust-free assembly workshop, constant temperature, constant humidity, the ground is smooth and can shine out of the figure, enter the workshop, to change shoes, put on snow-white cotton slippers.

Even if the parts assembly area, the final assembly area and the parts inspection area of the Hengshan turbofan engine are specially divided, the related experimental area only accounts for less than one-third of all the grand workshops, and now the rest of the place is pitch black.

The assembly workshop is put into application, and some parts of the Hengshan turbofan engine can also be assembled, and some technical staff are assembling the parts, such as turbine rotor assembly, combustion chamber assembly, compressor assembly, etc.

Accessories inspection area, the area is not small, a large inspection desk, neatly arranged, this is a professional inspection desk, each table has a thick layer of green rubber, can prevent parts from bumping and scratching.

Before the assembly of the aero engine, a large part of the inspection work has to be done, and the distributor sends the parts and accessories to the inspection area, and the inspector has to start his own work.

These inspectors first check some assembly size items of the parts again, measure the measured value, and after the measurement is completed, they will be selected.

Yang Jie, Wang Yonglin, Konstantin, and Liu Fuping accompanied Liu Jianqing and others to change into the special snow-white cotton slippers at the entrance of the final assembly workshop before they began to enter the workshop.

Walking to the parts inspection area, Liu Jianqing also watched with great interest as an inspector was measuring the journal of a turbine shaft, and there were several bearings next to it, which would be assembled on the turbine shaft, and the assembly part was the journal of the turbine shaft.

These bearings are produced by a German joint venture in China, an aero engine, tens of thousands of parts of various types, Yonghan Aviation Power Technology Co., Ltd. cannot produce all the parts by itself, on the contrary, many parts are purchased from home and abroad.

The global aviation industry's supply chain is well established, and there are not many restrictions on aero engine parts such as custom procurement.

Wang Yonglin also compiled a complete set of standard manuals in accordance with the production process standards of Rolls-Royce, and of course, Konstantin and others also participated in the formulation of the production process.

In the parts assembly area, Liu Jianqing saw that some parts had already begun to be assembled, and a middle-aged worker with a young worker was assembling the turbine rotor, and couldn't help but walk past.

Seeing Liu Jianqing and others coming over, the middle-aged worker also showed a surprised look on his face, and took the initiative to greet: "Hello chief!"

Then he also greeted Yang Jie and Wang Yonglin.

Liu Jianqing glanced at the middle-aged worker and said, "You are Miao Yi?"

"Chief, do you know me?" Miao Yi said in surprise.

"I still remember that you are a senior aero engine assembly technician at the Xi'an Engine Factory, and you have a lot of assembly work on your hands, but I didn't expect Yonghan Aviation Power Technology Company to poach you. ”

Miao Yi scratched his head and said in embarrassment: "Chief, the original factory was very difficult, and my wife's figure was not good, so it took a lot of money to see a doctor......

Liu Jianqing sighed and said: "I don't mean to blame you, it was really hard in the past, and it is very good that you can come to Yonghan Aviation Power Technology Company to work, and it has not caused bad talents." ”

He then looked at several apprentices beside Miao Yi, "These are the apprentices you brought?"

Miao Yi said: "Yes, they are all assemblers from several aviation companies. ”

Yonghan Aviation Power Technology Co., Ltd. has established a system of passing on the help at the beginning, and the new young employees will generally sign a mentor-apprentice contract with an old employee who has entered the factory for more than one year, forming a situation of bringing the old with the new.

Liu Jianqing asked with concern: "Do you have any problems during the assembly process?"

"The assembly was relatively smooth, and the size of the blades produced by our company was very accurate, and the assembly requirements were easily met when assembling. ”

"Well, you guys keep working. Liu Jianqing smiled and nodded.

Miao Yi asked several of his apprentices to weigh the blades before installing the turbine disc, and the weight of each blade should be weighed one by one using high-precision electronic scales, and recorded——

When waiting for assembly, it should be assembled according to the weight of the blades.

Zhang Kelong looked at these turbine disks curiously, and said to Wang Yonglin: "These turbine disks are really pretty, and they adopt a new design structure, right?"

Wang Yonglin smiled and nodded: "Yes, this is designed by Dr. Liu Fuping, pioneered in China, such a turbine disc structure design, not only lighter weight, but also greater strength." ”

"I have never seen such a turbine disc in my twenty years of work. Tang Zhengwang said.
