Yang Jie doesn't care about the attitude of the high-level people who want to use Huaxing Group as a whetstone to sharpen the domestic military industrial group company, those applause, flowers, and honors are superficial things for him, and what he really cares about in his heart is how to make something creative that amazes the world, which is the pride in his bones as a scientist.

He was more concerned about the development progress of the H-10 strategic red bomber than the launching ceremony of the prototype of the H-10 strategic red bomber.

The design of the H-10 digital prototype, which is based on the design of the Tu-160 strategic bomber, was completed a few months ago, and the prototype was officially put into production.

The main reason why the progress is so fast is that Song Daozheng has already figured out the fuselage mechanism of the Tu-160 before, and at the same time, Huake Aviation Technology Company has a deep foundation in the research and development of the aerodynamic layout technology and flight control system of the swept wing aircraft, and at the end of last year, it came up with the flight control system of the H-10.

This flight control system was taken to the flight control software test platform, and after half a year of testing, this flight control system also reached the design index.

After these key technological breakthroughs, the digital prototype of H-10 has also successfully completed all the processes, and all the designs have been fixed.

At the same time, most of the subsystem design drawings have begun to be handed over to domestic suppliers to start trial production.

Sinoking Aviation Technology's own factory undertook the trial production of the keel beam, the central wing box and the connecting mechanism between the swept wing and the central wing box of the H-10.

The size of the H-10 strategic bomber is about the same size as that of the H-7, with a longer wingspan and a rotatable swept wing size of more than 20 meters.

After a large number of calculations, simulations and tests, Sinoking Aviation Technology Co., Ltd. has made the size of the swept wing as small and light as possible.

Experts such as Song Daozheng and Zhang Hong racked their brains in order to reduce every kilogram of weight on the fuselage without affecting the flight performance of the aircraft.

The biggest defect of the previous variable-swept wing aircraft is that the rotation mechanism of the variable-swept wing is very complex, and the maintenance is complicated, the dead weight is very large, and because the wing box uses a large amount of titanium alloy, the processing cost is very expensive, and the other is that the variable-swept wing cannot carry more dàn yào.

But these deficiencies are no longer a big problem.

Because the H-10 is a strategic stealth bomber, the emphasis is on stealth capabilities, and the weapons are all buried in the stomach, and it is no longer a problem for the swept wing aircraft to carry weapons.

In addition, with the progress of processing equipment technology, the cost of titanium alloy and titanium matrix composite processing has also been greatly reduced.

Because Huaxing Group has ilmenite and rare earth ores, and has a complete set of industrial chains, the Machine Tool Research Institute has been conducting a lot of research on titanium related materials, and has also developed a variety of titanium matrix composite materials.

Unlike many domestic and foreign research institutions, many of these new materials are developed by material manufacturers to prepare materials of different specifications for sale, and many manufacturers have to explore their own processing methods after getting these materials, which requires the support of production equipment and tools, so the use of these materials has become very slow and the cost is very high.

After obtaining the ideal materials, the Machine Tool Research Institute immediately carried out various studies on the processing technology of these materials, so that these new materials can be prepared into the required components with special tools and equipment at a very fast speed.

Because Huaxing Group has matured in silicon carbide materials, the composite materials prepared are basically made of silicon carbide fibers, and the metal matrix composites prepared are very difficult to process.

Therefore, these subsidiaries of Huaxing Group will soon be able to use these materials in their own products.

Huake Aviation Technology Co., Ltd. naturally used lighter titanium matrix composite materials in the production of the central wing box and wing wing box of the H-10 strategic bomber, which greatly reduced the previous dead weight.

Because of the poor self-lubrication of titanium matrix composites, the Machine Tool Research Institute also prepares self-lubricating carbide-derived carbon coatings on the surface of silicon carbide and titanium-silicon carbon, so that these carbides are also self-lubricating under non-lubricated sliding conditions.

Yang Jie also deliberately went to the technical department of the rotating mechanism to understand the situation.

The wing structure of the fighter with the variable swept wing design is basically the same, and the two ends of the wing box are connected with the rotating shaft of the variable wing root, so that the wing can rotate with the rotating shaft as the center of the circle, and the wing rotation is controlled by the hydraulic action cylinder designed at the wing root.

The previous Damao hydraulic power unit used a mechanical hydraulic system, while Eagle Sauce's Grumman Group Company used an electro-hydraulic power assist system, adding a set of motors and electronic control units to the hydraulic pump, but there was still a booster oil tank, and there were still many hydraulic circuits in the fuselage.

The Huake Aviation Technology Co., Ltd. canceled the booster oil tank and directly used the electric pump to provide assistance, which canceled the hydraulic circuit to the greatest extent, and Huaxing Group was able to make the motor volume and weight very small, and the original hydraulic action cylinder was replaced by an electric hydraulic cylinder.

Previously, Grumman's Tomcat fighter left and right hydraulic action cylinder gearboxes had a hollow aluminum alloy coupling to ensure that the wings on both sides were synchronously retracted, but Huake Aviation Technology Company canceled it, and used the action positioning encoder on the swept wing shaft to synchronize the on-board computer control.

In order to ensure the reliability of the rear sweep wing, Huake Aviation Technology Company also backed up a set of electro-hydraulic action cylinders.

Now this set of electro-hydraulic action cylinders has been made, and the technical department is testing this set of action mechanisms.

Although the digital prototype has been simulated before, the actual product still needs to be tested and inspected in various dust, high and low temperatures, humidity, high salinity corrosion and other harsh environments.

Although the technical department has developed the electro-hydraulic action cylinder of the J-15 fighter before, the swept wing of the H-10 is larger and heavier, and the designed action mechanism must also strictly complete the testing process and standards.

In addition, Yang Jie also inspected the workshop of the central wing box and swept wing in the production workshop.

The main elements of the central wing box and the swept wing are made of titanium alloy, and these components are cast in a vacuum furnace and then forged with a 60,000-ton press, and the forged workpiece also needs to be sent to the CNC center for processing.

Only titanium alloy components forged by such a press-pressured can meet the performance requirements for which they were designed.

These machined titanium components also need to be welded into the frame of the wing box with a high-powered laser welding machine.

This time, a large number of titanium matrix composite materials are used in the main components of the four halves of the central wing box, such as wall panels, stringers, and angular parts, and these parts are also in the production process.

After the production of these parts is completed, they are also combined by titanium alloy rivets and fasteners to form a large component.

Because at the beginning of the design, components such as the central wing box were simulated and tested by digital assembly, and some parts have already begun to be assembled, and the speed is still very fast.
