Chapter 1672: Dormant (middle)

Although Xijing Group’s "Stealth Leopard" program was unsuccessful, the program has completed the first stage of program demonstration due to abundant funds and early planning, including the aerodynamic shape, body layout, main performance indicators and other parameters have been determined. After entering the substantive engineering development stage, it was also at this time that everyone discovered that these guys had long been unpredictable.
The "Stealth Leopard" program has determined the development direction of "one aircraft, two models" from the beginning, that is, a land-based model and a ship-based model are developed simultaneously, and the same working group is responsible for implementation. The same aerodynamic layout, the common rate of parts between the two will exceed 70%, but the shipboard model has made a lot of adaptive designs for the ship, for example, the wing area has been increased to obtain greater lift and lower The landing speed, such as the landing gear and fuselage structure has been strengthened, such as the addition of the tail hook, and all the mechanical components have been treated with salt spray resistance, etc. The superposition of these differences makes the ship-based model more than land-based The model is about one ton heavier, so the maneuverability and endurance have been reduced, but this is only relative, because they have already prepared a plan to deal with it-Lida Brick Fei.
The standard power system of this fighter is not the existing "Turbofan 12", but two "Turbofan 12B" with a maximum afterburner thrust of 10 tons!
Calculated in this way, the two engines of the "Stealth Leopard" can provide a maximum thrust of 20 tons, which is completely enough for such a fighter aircraft with an empty weight of less than 14 tons, and if the aerodynamic design is good, the aircraft can still In the case of low load, there is no need to use afterburner, and only military thrust can enter the supersonic flight with low Mach number!
After Xijing introduced the "Invisible Leopard" plan, all those who participated in the bid evaluation could only sigh: "You are hiding so deep..."
It turned out that as early as the "Turbofan 12" was just successfully developed and entered the first batch of equipment and practical stage, the Gas Turbine Institute has continuously promoted the model improvement and development on this line of engines. The internal code of the plan is "Turbofan 12B" "The goal is to increase the thrust of the engine to 10 tons and the thrust-to-weight ratio to 9.5!
Although this performance improvement is not comparable to that of the "EJ200" jointly developed by the four European countries, which reached a terrible thrust-to-weight ratio of 11, for China Xia, it is no less than another revolution in the field of aero engines!
However, both Liu Dayang and Cheng Ronghui, the lead designer of the new generation of aviation development responsible for this improved model, have shown great confidence in completing the engine on time, because this engine is fully developed by the Gas Turbine Institute. In other words, the research institute knows every detail of this type of engine, and of course it has a full understanding and expectations of its current state of deficiencies and future development potential, and the standard delivery performance based on engineering products must be retained. With a margin for this global standard, the team believes that they should soon complete the basic design work of the "turbofan 12B" and transfer it to the formal development of the model.
Of course, being able to have such confidence is also due to someone's unremitting money-burning investment in the field of various basic materials, the continuous progress of his subsidiaries in the field of precision machining, and the promotion of Under the circumstances, the iterative development of the semiconductor industry and the innovation of the chemical industry... For complex and sophisticated electromechanical products such as Hangfa, each advancement of it is actually a sign of the continuous improvement of national strength, and it is also the national basic industrial capabilities and scientific research. A sign of continuous improvement!
It is also at this time, when someone looking back on the past, they will discover the fact that China’s aviation industry can be as prosperous as it is today. It originated from 20 years ago when there was a young man wearing clothes of no more than ten yuan. People, came to the magic city, walked into the rudimentary dormitory of the chief aircraft commander who was about to be put to rest...
Although the "Stealth Leopard" failed to gain the favor of the Air Force, its shipboard model was unsurprisingly favored by the Navy. Since several other major Chinese aircraft manufacturers did not make preparations for this, it was natural. It is hard to talk about the profound technical accumulation. Therefore, it is almost certain that the aircraft will be recognized by the Navy, and the relationship between the XAC Group and the Navy is also unmatched by other domestic factories. This is a fact that everyone defaults. .
However, as the Navy’s first aircraft carrier successfully launched sea trials, the huge cake of fixed-wing fighters on the ship certainly cannot be swallowed by XAC. The first-generation fighters on board have been monopolized by XAC. The second-generation stealth fighters are expected to be included in the bag, how can it be? Without competition, how can technology advancement and price decline be promoted?
Therefore, someone must stand up to break the monopoly of XAC.
Does Shengjing Group think this is the case? As the big brother of the China Aviation Plant, it is naturally me.
And they also came prepared this time.
The second plan that Shengjing Group launched this time is the Chinese version of "Jacque 41" that they prepared in case the new fighter loses the election.
In fact, after many rounds of plan modification, Shengjing’s plan has been very different from its original Rakshasa version, or in other words, it has been completely modified to even the mother of "Jacques 41" Raksha Yakovlev’s design bureau can’t even recognize it—well, this is an old tradition in China’s aviation industry. Otherwise, the old man "Hang Liu" would not often lament why there are only 26 English alphabets. Letters are not enough...
The solution launched by Shengjing Group adopts a stealth-type fuselage structure. A magazine is arranged on both sides of the belly and the fuselage, so that this type of fighter can perform stealth air combat missions with "4 in The missile’s loading capacity is near 2", with an empty weight of 11 tons and a maximum speed of Mach 1.7. The maximum take-off weight varies greatly depending on the take-off mode, up to 25 tons, and the range varies greatly depending on the combat profile. Under ideal conditions, the maximum combat radius can reach 1,000 kilometers. It is planned to use a "turbofan 15" engine with a vector propulsion capability under development and a maximum thrust of 15.5 tons as power, and two lift engines with a thrust of 4.2 tons. For the aircraft to achieve vertical/short takeoff and landing capabilities.
There is no doubt that in terms of air combat capability alone, this type of fighter is obviously at a disadvantage when facing the "new fighters" launched by the Rongcheng Group and the Xijing Group, but its biggest advantage is that it can take off and land vertically!
In other words, this type of fighter, like the 12 "Sea Harriers" regarded as treasures by the Navy for a long time, can even take off and land and perform tasks on a simply modified freighter, and the contrast is the same. For a helicopter that does this, its combat power is much higher by several orders of magnitude!
And this capability is simply too important for the battlefield shielding mission that must be performed during landing operations. With this capability, the Navy can use amphibious assault ships that are much cheaper than aircraft carriers to carry these aircraft, and landing forces can also Calling air support in the simplest and fastest way, the ability to strike time-sensitive targets against the enemy has also jumped by several orders of magnitude!
Dear friends of the Navy, does it smell?
Xiang, it's so sweet, that is, that, Academician Gu and Academician Li, did you write a few more zeros for the suffix of the research and development budget cost you reported?
