Qi Yiming didn't tell him why he was invited to Xifei before he arrived, but he was completely shocked after he went there.

XAC is now the busiest among all aircraft companies, and it is also the company that has diverted the most red-alert engineers from Qi Yiming. Not only do they have to complete the digestion and absorption of Feibao, they also have to improve the operation of Yun-8 and Yun-8.

The production work of Y-9, Y-12, Y-20 and other types of transport aircraft, on the other hand, is also the development and absorption of special aircraft such as early warning aircraft, tankers, anti-submarine aircraft, etc. It is really busy.

Among the state-owned enterprises that have obtained the various technical information provided by Qi Yiming, the ones that have made the fastest progress are the R&D enterprises of heavy industrial equipment such as No. 1 and No. 2. They have certain technical reserves and the difficulty of imitation is relatively low. Moreover, there are

Red Alert Engineers have started to provide large-scale presses, smelting equipment, etc. to many companies. Next in line is the 617 Factory, an enterprising army equipment company. The Rhino tanks they produce have begun to be delivered to other countries for use. On this basis

They have already begun the development of the light tank Grizzly and the heavily modified MBT-2000 Rhino II tank.

Xi Fei has always been a quiet person, but this time Qi Yiming's eyes almost fell out of shock.

They actually modified Fei Bao themselves. Moreover, they carried out this work with the support of the Air Force. Qi Yiming had almost never heard of this news before.

A large number of Red Alert engineers with full technical experience, together with the engineering and technical personnel who were originally used by XAC to build the Flying Leopard, were not satisfied with following the same pattern in the Flying Leopard from the beginning. The Air Force Equipment Department also issued a warning on the Flying Leopard very early on.

The technical requirements of the Flying Leopard have been modified to be different from those of the HNA version. The Flying Leopard has had obvious HNA characteristics since its birth. Its main combat advantage lies in its ability to mount a variety of anti-ship missiles and skim the sea at low altitudes to raid large enemy fleets.

, and its relatively conservative design is not so advantageous for the Air Force in complex terrain and weather environments.

It can be seen from Fei Bao's service experience in Qi Yiming's timeline that after Fei Bao joined HNA, he was expected to be a tough soldier, and he had been involved in major accidents under the Air Force one after another.

At the beginning, the Air Force Equipment Department hoped that XAC could make the Flying Leopard into a two-seat parallel fighter-bomber, and if possible, add a variable sweep wing system to improve its low-altitude performance, and use better engines to improve performance.

Bomb load and range. At first glance, this seems to be imitating the Su-24, and in Qi Yiming’s evaluation, it goes against the times. He admitted that there are many problems with the design of the Flying Leopard, but precision strikes outside the defense zone are the future.

The only way out for the development of fighter-bombers is that some people actually want to go back and develop two-seat parallel and variable sweep wings. It is really unbelievable.

However, this request was stopped after Qi Yiming provided the Air Force with the first batch of 16 H-6Ks, which have a combat radius of 3,500 kilometers, a bomb load of 12 tons, and can carry 6 Changjian-10 cruise missiles with a range of 2,000 kilometers.

missiles, and the Changjian-10 is also capable of carrying nuclear warheads, so the Air Force wisely believes that it is meaningless to build a two-seat parallel flying leopard with variable sweep wings.

The Air Force had a lot of funds at hand, and after the reorganization and elimination of personnel, it felt that it was relatively surplus. There was no point in keeping it, so the restless Air Force Equipment Department once again flew west and issued a second improvement plan for the Air Force version of the Flying Leopard.

, the goal is still to distinguish the HNA Flying Leopard, but the specific significance is questionable. This time the Air Force is more fashionable and wants to engage in dual-mission heavy-duty Flying Leopards.

Hainan Airlines will definitely begin to equip the heavy air superiority fighter F-14 in 2086. Qi Yiming is still vague about the air force version of the heavy air superiority fighter. The J-10 is powerful and can conquer the world, but after all, it is a bit small.

Compared with the F-14, it is still a bit weaker. The Air Force, which does not want to lose its momentum, does not have the strength to develop a new heavy-duty air superiority aircraft, but with the help of the Feibao platform, it should not be a problem.

It turned out that XAC’s engineers didn’t know what the dual-mission fighter was like, so they went to consult the Red Alert engineers who had recently joined the company. The Red Alert engineers directly removed some information on the F-15E and Su-30 from the database.

Come out and put it in front of everyone and say, this is a dual-mission fighter.

Huang Dawei, general manager of XAC, felt as if he had found a treasure and immediately made the decision: "Compared with these two aircraft, let's change it to Flying Leopard!"

To modify the dual-mission aircraft, the Feibao was almost chopped into pieces and reassembled. The workload was quite heavy, but everyone at XAC was very motivated and the project went relatively smoothly.

Our country's North Korean engineers are very capable in reverse engineering and copycatting. In the past, there was no one to imitate, so the starting point was low. Now a group of engineers, big and small, are comparing the F-15E and Su-30 to modify the Flying Leopard. Although it sounds quite ridiculous, but people

It’s really been done. Many people think that enlarging the body and grafting aircraft parts is a mockery of engineering, but in fact this kind of thing happens frequently. Let’s not talk about it far, let’s talk about the F-20 Tiger Shark fighter

, is actually the product of this kind of grafting, and the Super Seven, which is no longer possible in this plane, is actually the plan of grafting the J-7 to other aircraft.

First, a group of engineers made the Feibao's mid-flat head larger, and the canopy was also changed to a two-trunk type to improve the visibility of the aircraft. The basic model even eliminated the rear seat, and when viewed from the side, a relatively large change occurred in the cockpit.

The changes make it appear fuller. In addition, the F-15E's adjustable external pressure four-wave air inlets are installed on both sides of the nose. The wings are still upper monowings, but due to the unstable layout,

The lower dihedral angle is cancelled. What is even more unscrupulous is that because the original Flying Leopard's wing has a fillet at the wing root, an aerodynamic twist on the outer wing, and a wing blade with leading edge serrations, the New Magic modified the Flying Leopard's wing.

It is basically grafted onto the Su-30 wing, but the large area of ​​the vertical tail has also been changed to two 90-degree double vertical tails. The area of ​​the horizontal tail has also been increased and changed to a full-motion type. Almost everything is for aerodynamics.

In Qi Yiming's view, the new aerodynamic shape is somewhat of a trap. It does not absorb the excellent wing-body fusion of the Soviet fighter jets, nor does it have the fixed-curvature leading-edge tapered twist of the F-15. It is relatively safe and practical.

designed.

The two Spey engines were abandoned and replaced directly with two WS-10D (a simplified version of the WS-10A, which reduced its own weight and thrust, with a thrust-to-weight ratio of 120 kN and a thrust-to-weight ratio of 7.6). In addition, the engine on the belly of the fuselage

The modification is relatively large. This is because the masters of the copycat project have integrated the F-15 pylon design. Two light-load hanging points are arranged under the inlet, mainly for hanging pods, on both sides of the inlet.

A pair of bulging conformal fuel tanks are also affixed, with a total of 6 light-load hardpoints installed on them, mainly for hanging various weapons under 250 kg. In the center of the air inlet is a heavy-load hardpoint for hanging auxiliary fuel tanks. Two

The bottom of the main wing near the conformal fuel tank is also a heavy-duty hardpoint. With the composite pylon, one auxiliary fuel tank and two air-to-air missiles can usually be hung. Because the Magic Flying Leopard has wingtip pylons, two short-range air-to-air missiles can also be hung there.

This kind of bomb-mounting layout is almost a complete copy of the F-15E. Compared with the HNA version's main parallel-mounted under-wing layout, the tandem mounting resistance is much smaller. However, relatively speaking, the HNA version of the aircraft is still suitable for mounting large anti-ship missiles. The Leopard is stronger. Basically, this new type of modified Flying Leopard is mainly used to mount small and medium-sized guided bombs under 500 kilograms during ground attacks, and is not designed to mount anti-ship missiles.

Changing the engine, changing the bomb layout, changing the aerodynamics, adding conformal fuel tanks and other improvements have directly enabled the new Flying Leopard to have a maximum range of 4,200 kilometers, a maximum load of 10.5 tons, and a maximum airspeed of Mach 2.2. Even greater The radar also provides the new Feibao with greater room for improvement of the avionics system. There was originally an idea to install the same AESA as the J-10, but considering the cost issue, the prototype used the domestically produced 1474 all-weather multi-purpose Doppler pulse For targets with RCS = 5 square meters, the radar has an upward-looking detection range of 180 kilometers and a downward-looking detection range of 110 kilometers. The parameters are not much worse than the F-15 using APG-63. It is said that XAC originally planned to use Shenfei to improve the F-14 This company obtained the more powerful AWG-9 radar from Hughes Company, but the funds were still insufficient, so they chose the 1474 radar. Fortunately, the electronic level of the base-produced new radar is relatively high and the degree of digitization is better. In terms of response, It is faster than the current radar of the APG-63 family.

Of course, because the changes were too large, the Modified Leopard was sent back to the wind tunnel like a new aircraft, and everything had to be redone. Fortunately, a group of Red Alert engineers had a relatively high level, and some of the equipment brought by the Red Alert base The technologies are also very mature. From avionics to flight control systems, engines to weapon systems, they are all ready-made. There is no need for designers to conduct any further exploration. Most of the flaws that appear are small flaws that are easier to improve. There are no It turns out that Feibao went through so many twists and turns from design to completion.

It can be seen that in the aviation industry, technical reserves and R&D experience are very valuable assets. With a group of technical personnel and a large amount of reserve information provided by the Red Alert Base, the country's aviation industry can quickly form a set of specifications and condense Come up with your own model.

Since a large number of designs came from copycats, coupled with the paperless, all-digital design environment, it only took more than seven months from the new design drawing to the prototype. Qi Yiming also had to work for Xi The efficiency of Feiyi designers is amazing.

When Qi Yiming came to Yan Liang's test airfield and saw this JH-7B modified fighter jet codenamed "Flying Cloud Leopard", he had a deeper understanding of the power of the Red Alert engineers.

Leopard B looks almost incompatible with Leopard A. Its appearance is already a standard third-generation aerodynamic shape, and the concept of conservatism has been forgotten. I don’t even know who is so heartless. This prototype was painted with leopard print, which made Qi Yiming's balls ache.

The test flight of the prototype went very smoothly. After the Leopard B took off, it simply performed some routine maneuvers in the air without retracting its landing gear. It seemed relatively smooth and there were no major problems. Qi Yi Ming also feels that this aircraft is basically a thing built by a group of people with mature technology. It doesn't count as brand new, and the progress will be faster.
