Chapter 898: Digital Mockup!
In the monitoring room of the test workshop, the engine of the internal model of Hengshan 5A is being tested in different power states on the test bench, and the huge tail sprays a strong blue flame into the exhaust channel at this time.
An hour later, the engine completed a series of test tests, and the parameters displayed by the engine also reached the design index, at this time, the staff in the monitoring room suddenly burst into warm applause.
Zhang Haiping also shook hands with Konstantin, Wang Yonglin and others with a smile on his face, "Your work is very good!"
Although the engine will have to go through hundreds of hours of ground test tests, and then thousands of hours of high-altitude tests, the current test test is undoubtedly a very good start.
He knew that Yonghan Aviation Technology Company had carried out a test cycle of up to 10,000 hours in terms of materials before development, and many parts of the core aircraft had been tested a lot before this, which also ensured the reliability and stability of the engine, and also established a set of very rigorous and meticulous design, development and manufacturing standards, and he was very confident in the engine products of Yonghan Aviation Technology Company.
Later, in a conference room, Song Daozheng, He Hongfeng and others reported to Zhang Haiping and Yang Jie on the research and development progress of H10 at this time.
The aerodynamic layout of the H-10 strategic bomber has been determined, and the aerodynamic layout of the Tu-160 strategic bomber has been improved in stealth, although it is said that the design of the rear-swept wing is adopted, but the main wing area has become larger, the size of the swept wing has been reduced, and the wing-body fusion technology has also been adopted, compared with the previous Tu-160, there is no long nose, but has become an obvious diamond-shaped shape.
The edge of the magazine under the belly is designed to be zigzag, and the wedge-shaped adjustable air intake of the original Figure 160 has been replaced by a mussel air intake, with a large bag bulging out of front of the semicircular air intake, which extends all the way inside.
This kind of clam air inlet technology has technical reserves in Chengfei, and it has also been technically verified in the Thunder Dragon fighter, and now it is also mature in this regard, so Huake Aviation Technology Company has also carried out technical cooperation with Chengfei.
Because the rectangular intake requires a defat on the back of the aircraft, the weight of this set of defers can reach almost 200 kilograms, and it is also disadvantageous for stealth.
Because Huaxing Group has always had a close cooperative relationship with Chengfei, Chengfei transplanted its own clamshell air inlet technology.
In addition, the technical team led by Song Daozheng also improved the stealth design of the tail, and the size and shape of the horizontal tail and the vertical tail have become very different.
This design scheme is selected from dozens of design schemes, these design schemes are made to make a model in the wind tunnel and in the dark wave chamber to do the radar wave reflection area test, this technical scheme test data is the best, the company then finalized this technical scheme.
Because Song Daozheng had figured out the structure of the Tu-160 before this, and also made a wooden prototype, and Huaxing Group had already figured out the flight control and manufacturing of the rear-variable swept wing aircraft because of the imitation and improvement of the F-14 Tomcat fighter, and because of the design and manufacture of the Shadow UAV project, there was a lot of technical accumulation in stealth coatings and stealth layouts.
Therefore, after the plan was determined, Sinoking Aviation Technology Company also made a digital prototype last week, and is testing the shape, assembly and function of the product.
Huaxing Group began the construction of digital simulation system six years ago, and under the full promotion of Yang Jie, all its companies have introduced digital simulation system technology.
The traditional product development process is from product design to processing and manufacturing, trial and testing, and then pour the results analysis, while in the modern product development process with the introduction of digital prototype technology, the digital model and test are mentioned before the product processing and manufacturing.
Digital prototype technology is not only the application of some software, Huaxing Group in the introduction of this digital simulation system in the organizational structure, process tools and culture and other aspects are followed by a significant adjustment, this process is also a lot of people do not adapt and pain, after all, many engineers must learn to master these digital simulation software, and the R & D process has changed, need an adaptation process.
Under the strong promotion of Yang Jie, Huaxing Group spent several years to complete the construction of the digital simulation system and built a digital collaborative R&D platform, which is the resource layer, the support layer, the application layer and the display layer.
In terms of resource layer, it includes basic databases, knowledge bases, and tool resources, among which the basic databases include experimental data, digital models, design specifications, material libraries, and parts libraries of Huaxing Group for so many years.
The knowledge base includes design template library, simulation template library, optimization template library, algorithm encapsulation, experience specification library, etc.
The tool resources are various computer-aided design software and computer-aided engineering software developed by the digital simulation software department of Huaxing Group, as well as software imported from abroad.
With the resource layer, Huaxing Group has established a support layer, including the management system that coordinates various departments, and has established various design systems in the process of practical application.
At present, the subsidiaries of Huaxing Group have formed a digital design of the whole cycle of product research and development through digital simulation technology for virtual modeling, working condition simulation, component optimization and virtual manufacturing.
With the integration of relevant conceptual, mechanical and electrical design data, Huaxing Group has become more and more complete in digital simulation, which has greatly shortened the cycle of product design, development and manufacturing, reduced costs and greatly reduced the error rework rate, which has brought great benefits to the entire Huaxing Group.
Song Daozheng and He Hongfeng and other technical talents were quite unaccustomed to joining Huake Aviation Technology Company at first, they had to learn to master these digital simulation software and follow the new process, but after they adapted, they also deeply felt the great convenience brought by this digital simulation system - the digital prototype almost took more than three months to complete!
Now it is only necessary to complete the process of optimizing and validating the product virtually, and then move on to the manufacturing process of the physical prototype.
Because the development process of the digital prototype is strictly carried out in accordance with the actual aircraft, it can be used to simulate the experimental verification of various prototypes in the simulation environment, and continuously optimize to obtain the best solution.
If according to the previous development process, after the design plan comes out, it is necessary to establish a physical prototype to carry out various verifications, and constantly modify the design plan, which is time-consuming and laborious.
With this platform, the best design solution can be obtained through continuous verification of digital prototypes during the design phase.
Although it is said that the physical prototype still needs to be built in the manufacturing process, most of the fault defects have been solved at the beginning of the design of the assembly and other problems in the production and manufacturing, and only a few physical prototypes can complete the prototype finalization.
It can be said that this platform has played a huge role in accelerating the development progress of the H-10, a strategic bomber!
