Chapter 610 Panshan Engine
The first thing Liu Tao solved was the J-10 avionics system.
Based on the avionics system of the ‘Eagle’ advanced trainer, a certain upgrade was made. Such an avionics system is already very advanced and sufficient for the J-10.
The displays will be specially manufactured and produced. Unlike civilian ones, they are safe, stable and highly resistant to interference.
The inertial navigation system directly introduces the ‘Beidou Navigation System’, allowing it to provide navigation for the J-10 anywhere in the world. At the same time, it can provide comprehensive information such as the aircraft’s real-time position, pitch/roll, attitude, heading, acceleration and speed together with the attitude/direction reference system.
The electronic warfare system can provide threat warnings and implement electronic countermeasures against selected threats at the same time. The towed decoy is used to supplement traditional radar jamming methods to deal with modern radar-guided missiles. The decoy can simulate enemy radar signals and induce the guidance head to lock on itself instead of the aircraft.
The multifunctional pulse Doppler radar has a detection range of 190 kilometers and a tracking distance of 100 kilometers. It will play the role of "clairvoyance" for the J-10 fighter, and can detect enemy aircraft early. When the enemy aircraft enters the attack range of the J-10 fighter's air-to-air missiles, it can launch an attack. At the same time, it can look down to search for targets, and use the Doppler effect to avoid the target's signal being covered by ground noise. It can track small targets from out of sight to close distance and treetop height.
In terms of avionics systems, it can be said that the J-10 far exceeds the J-7 and J-8 series fighters, which are not at the same level at all.
After getting the avionics system, Liu Tao also took on the task of developing high-performance aircraft engines suitable for the J-10 fighter.
Song Wencong and others are doing their best to modify the aerodynamic layout structure of the J-10.
Liu Tao went to Panshan Machinery Factory, which has the most advanced processing center in the country.
Liu Tao first designed a larger turbofan engine based on his understanding of the WS-2M.
For an advanced aircraft engine, it takes five to ten years to develop the core engine, and several more years to develop the verification engine. Finally, it takes more than ten years to develop the engineering engine.
This is why the number of countries in the world that can develop high-performance aircraft engines can be counted on one hand.
Other countries may have the ability to develop advanced fighter jets, but they have to import aircraft engines.
The price of aircraft engines is definitely not cheap.
However, it is different for Liu Tao. With the golden finger, he can save a lot of time and money.
It took a month to produce a large aircraft engine.
Liu Tao put his hand on this large aircraft engine, and the virtual panel emerged.
[Item: Panshan Engine]
[Manufacturer: Liu Tao]
[Item Level: LV1 (0/10)]
[Upgrade Points: 2500]
[Item Status: Intact, Analyzable]
Seeing the 2500 upgrade points, Liu Tao was amazed. He developed such an aircraft engine and made it himself, and it actually had 2500 upgrade points.
The development level of aircraft engines is regarded as a concentrated reflection of a country's comprehensive national strength, industrial foundation and scientific and technological level. It is praised as the most advanced technology and the most advanced industrial success in modern industry, which is not without reason.
An aircraft engine is very complex, using many advanced materials and has very high processing requirements.
The most used materials here are aluminum alloy and titanium alloy!
Aluminum alloy has outstanding advantages such as high specific modulus and specific strength, good corrosion resistance, good processing performance and low cost, so it is considered to play a vital role in the aviation industry. The main application locations are engine compartment, cabin structure, load-bearing wall plate, beam, instrument installation frame, fuel tank, etc.
Titanium alloy has the advantages of high strength, good corrosion resistance, good fatigue resistance, small thermal conductivity and linear expansion coefficient, and its main application locations are compressor blades, casings, engine compartments and heat insulation boards of aircraft engines.
As for other new materials, there are as many as a dozen.
Then, Liu Tao began to test.
It is not cost-effective to directly smash the upgrade points at the beginning, or to accumulate experience points by starting up the machine first.
As long as the experience points are sufficient, Liu Tao will upgrade.
It took a full month, and the engine ran for 744 hours without interruption. Liu Tao upgraded the engine compartment, cabin structure and other parts.
Then, he began to smash the upgrade points.
Swish, swish, swish~~~
A series of faint lights flickered.
This aircraft engine seemed to have a series of streams of light on its fuselage.
When the faint light disappeared, the "Panshan Engine" in front of him had undergone some inexplicable changes.
The lines are smoother and more beautiful!
Liu Tao started the "Panshan Engine", and the engine burst into a shocking roar.
Through this sound, Liu Tao immediately knew that the power it generated was much stronger than before.
After running for about half an hour, Liu Tao turned off the engine.
At the same time, Liu Tao's virtual panel appeared:
[Item: Panshan Engine]
[Manufacturer: Liu Tao]
[Item Level: LV10 (not upgradeable)]
[Upgrade Points: 500]
[Item Status: Intact, can be analyzed]
Liu Tao looked at the note behind LV10 that said it could not be upgraded with a slight hesitation. He knew that the original aircraft engine, even if the materials used were very good, was still not enough to allow it to have the potential to be upgraded to level 11.
If you want to upgrade to a stronger one, you have to rebuild one according to the standard of this aircraft engine. However, by then it will be a brand new aircraft engine, and upgrading it will be a re-upgrade.
Liu Tao looked at the detailed data, thrust-to-weight ratio 7.86, maximum thrust with full afterburner/no afterburner 144.6/86.2kN, mass 1837kg, bypass ratio 0.68, air mass flow 124.7kg/s, total pressure ratio 33.3, turbine pre-temperature 1750~1800℃, maximum diameter 1.18m, length 4.8m.
The service life of the engine reaches 3500 hours.
It can be said that the performance of this aircraft engine is very good. Even at the edge of the J-10 flight envelope, the engine thrust is very strong, enough to give the J-10 powerful power.
"System, analysis!" Liu Tao muttered.
Suddenly, a series of drawings were automatically formed on the virtual panel, which were the design data of this "Panshan engine".
It contained the material formula, processing technology, etc. of each position.
After the analysis was completed, Liu Tao began to arrange people to conduct a series of professional tests on this "Panshan engine" and produce more "Panshan engines".
The engine test is very multifaceted, including testing the engine's life, testing the normal thrust and maximum thrust of the engine, the stability of the engine, etc.
After Liu Tao made the arrangements, he set off for the 611 Institute.
After solving the engine problem, the J-10 can also start to arrange the manufacture of the prototype.
The manufacturing of the J-10 prototype was not in Guifei, but in Chengfei.
Of course, it does not mean that everything about the J-10 is manufactured in Chengfei. For example, many avionics systems are produced in Panshan Group and then transported to Chengfei.
There is also the "Panshan engine", which is also produced by Panshan Group, and finally the whole unit is transported to Chengfei for installation.
Chengfei should be said to be the final assembly of the J-10 prototype.
