Qi Yiming didn't tell Wei Lu what he had invited him to go before he flew to the west, but he was completely shocked after he passed.

Xifei is now the busiest of all aircraft companies, and it is also the company with the largest number of red alert engineers who have taken Qi Yiming, not only to complete the digestion and absorption of flying leopards, but also to improve the production of multiple types of transport aircraft such as Y-8, Y-9, Y-12, and Y-20, and on the other hand, there are also special aircraft such as early warning aircraft, tankers, anti-submarine aircraft, and other special aircraft development and absorption.

Among the state-owned enterprises that have obtained all kinds of technical information given by Qi Yiming, the fastest progress is the research and development enterprises of heavy industrial equipment such as one heavy and two heavy, they have a certain technical reserve, and the difficulty of imitation is relatively low. Next in line is the 617 Factory, an enterprising army equipment enterprise, whose Rhino tanks have begun to be delivered to other countries, and on this basis, they have begun to work on the development of the light tank Grizzly and the MBT-2000 overhauled Rhino II tank.

And Xifei has always been inconspicuous, but this time Qi Yiming's eyes were about to fall off.

They actually changed the flying leopard themselves. Moreover, they are still carrying out this work with the support of the Air Force, and Qi Yiming has almost never heard of this news before.

A large number of Red Police engineers with full experience in the field of flying leopards, together with the engineering and technical personnel who originally flew west to make flying leopards, were not satisfied with painting flying leopards from the gourd from the very beginning, and the Air Force Equipment Department also issued technical requirements for modifying the flying leopards to distinguish them from the HNA version very early. The main combat advantage of the Flying Leopard is that it can carry a variety of anti-ship missiles and raid large enemy fleets at low altitudes, while its relatively conservative design is not so handy for the Air Force in a more complex terrain and weather environment.

It can be seen from Qi Yiming's service experience in the timeline that after the flying leopard entered the HNA period, he was a fierce general, and he had major accidents under the command of the Air Force three times and five times.

At first, the Air Force Armament Department hoped that the Flying Leopard could be made into a two-seat parallel fighter-bomber, and if possible, a variable sweep wing system would be added to improve the performance at low altitudes, and a better engine would be used to increase the bomb load and range. At first glance, this is an imitation of the Su-24, and with Qi Yiming's evaluation, it is against the times. He admitted that there were many problems with the design of the Flying Leopard, but precision strikes outside the defense zone were the only way out for the development of war-bomber aircraft in the future, and it was really inconceivable that some people would want to go back and engage in two-seat parallel and variable sweep wings.

However, this requirement was stopped after Qi Yiming provided the Air Force with the first batch of 16 H-6Ks, with a combat radius of 3,500 kilometers, 12 tons of ammunition, and six Long Sword-10 cruise missiles with a range of 2,000 kilometers, and the Long Sword-10 also has the ability to carry nuclear warheads, so the Air Force wisely thinks that there is no point in engaging in two-seat parallel and variable swept wing flying leopards.

The Air Force has a lot of funds in its hands, and after the personnel are reorganized and dismantled, they also feel that they are relatively redundant, and there is no point in keeping them in their hands, so the restless Air Force Equipment Department once again issued a second improvement plan for the Air Force version of the Flying Leopard to the West, and the goal is still to distinguish the HNA Flying Leopard, and the specific significance is doubtful. This time, the Air Force is a little more fashionable, and it is going to engage in a dual-mission heavy flying leopard.

Hainan Airlines will definitely begin to equip the heavy air superiority fighter F-14 in 86 years, Qi Yiming's air force version of the heavy air superiority fighter is still in the ethereal, J-10 is strong and all-encompassing the world, but after all, the body is a little smaller, and the F-14 is still a little weaker, and the Air Force, which does not want to lose momentum, does not have the strength to re-develop a new type of heavy air superiority, but with the help of the Flying Leopard platform magic change, it should not be a problem.

It turned out that the engineers of Xifei didn't know what the dual-mission fighter looked like, so they went to consult the Red Alert engineers who had recently joined the company. The Red Alert engineers dropped part of the information of the F-15E and Su-30 directly from the database, and put it in front of everyone and said that this is a dual-mission fighter.

Huang Dawei, general manager of Xifei, immediately clapped his hand and said: "Compared with these two aircraft, let's change to fly leopard!" ”

To change the dual-mission machine, it is almost necessary to chop the flying leopard and reorganize it, which is quite a lot of work, but the motivation of the people in Xifei is also very high, and the project is going relatively smoothly.

China's North Korean engineers reverse engineering and copycat skills are quite strong, there was no imitation object before, so the starting point is low, now a group of large and small engineers compared to the F-15E and Su-30 magic transformation flying leopard, although it sounds quite ridiculous, but people really did it. Many people think that enlarging the body and grafting aircraft parts is a mockery of engineering and engineering, but in fact, this kind of thing happens repeatedly. Far from it, let's just say that the F-20 Tiger Shark fighter is actually this grafting product, and the super seven that is no longer possible to appear in this plane is actually the plan of the J-7 to graft other aircraft.

First of all, a group of engineers adjusted the middle flat head of the flying leopard to a larger size, and the cockpit canopy was also replaced with a two-carcass type to improve the visibility of the aircraft. The basic model even cancels the rear seats, and the cockpit has undergone a relatively large change from the side view, making it appear fuller. In addition, the F-15E's adjustable external pressure four-wave system air intakes are installed on both sides of the nose, and the wing is still the upper monoplane, but the lower reverse angle is canceled because of the unstable layout. What's even more undisciplined is that because of the very conservative and backward design of the original Flying Leopard wing wing with corner filling, outer wing with aerodynamic torsion, wing knife and leading edge serration, etc., the wing of the new magic change Flying Leopard is basically grafted with the wing of the Su-30, but the large area of the vertical tail has also been changed to two 90-degree double vertical tails, and the flat tail area has also been increased, and it has been changed to a full-motion type, almost everything is for aerodynamics. In Qi Yiming's opinion, the new aerodynamic shape is somewhat a bit of a tiger rather than an anti-dog, and the excellent wing-body fusion of the Soviet fighter has not been absorbed, and there is no leading edge cone torsion of the fixed curvature of the F-15, which is a relatively safe and practical design.

Two Spey engines were abandoned and directly replaced with two WS-10D (a simplified version of the WS-10A, reducing the dead weight and thrust, the thrust-to-weight ratio was 120 kN, and the thrust-to-weight ratio was 7. 6）。 In addition, the modification in the belly position is relatively large, because the masters of the copycat project have integrated the Pylon design of the F-15. Two light-load hardpoints are arranged under the air intake, mainly for hanging pods, and a pair of bulging conformal fuel tanks are also pasted on both sides of the air intake, on which a total of 6 light-load hardpoints are installed, mainly for hanging various weapons below 250 kg. In the center of the intake tract is a heavy-duty hardpoint for hanging the auxiliary fuel tank. The two main wings near the conformal fuel tank are also heavy-duty hardpoints, and with the composite pylons, one auxiliary fuel tank and two air-to-air missiles can generally be hung. Because the Magic Leopard has wingtip pylons, two short-range air-to-air missiles can also be hung there.

This almost completely copied F-15E's bomb hanging layout, compared with the main parallel hanging under the wing layout of the HNA version, the tandem mounting resistance is much smaller. However, relatively speaking, the large anti-ship missile or the HNA version of the Flying Leopard is stronger, basically this type of new magic Flying Leopard is mainly used to carry small and medium-sized guided bombs of less than 500 kg when attacking the ground, rather than designed to mount anti-ship missiles.

Improvements such as changing the engine, changing the bomb layout, changing the aerodynamics, and adding a conformal fuel tank directly made the new Flying Leopard have a maximum range of 4,200 kilometers and a maximum payload of 10. 5 tons, the maximum airspeed also reached 2. Mach 2. Larger radar also provides greater room for avionics system improvement for the new flying leopard, originally had the idea of installing the same AESA as the J-10, but considering the cost, the prototype uses the domestic 1474 all-weather multi-purpose Doppler pulse radar, for RCS = 5 square meters of targets, the upward detection range is 180 kilometers, the downward view is 110 kilometers, and the parameters are not much worse than the F-15 using APG-63. It is said that Xifei originally planned to use Shen Fei's improvement of the F-14 to obtain Hughes's more powerful AWG-9 radar, but the funds were still not satisfied, so the 1474 radar was still chosen. Fortunately, because the new radar produced by the base has a higher electronic level and a better degree of digitization, it is faster than the current radar of the APG-63 lineage.

Of course, because of the big changes, the magic leopard was beaten back to the wind tunnel like a new plane, and everything had to be restarted. Fortunately, the level of a group of Red Police engineers is relatively high, and some of the skills brought by the Red Police Base are also very mature, from avionics to flight control systems, engines to weapon systems, are all ready-made things, and there is no need for designers to carry out any kind of exploration, most of the small flaws that appear are relatively easy to improve, and there are not so many twists and turns in the original flying leopard from design to completion.

It can be seen that in the aviation industry, technical reserves and research and development experience are very valuable assets, with a group of technical personnel and a large number of reserve materials provided by the Red Police Base, the country's aviation industry can quickly form a set of norms, but also condense a set of its own model.

Due to the fact that a large number of designs come from cottages, coupled with a paperless and all-digital design environment, it only took more than seven months from the new design drawings to the prototype, and Qi Yiming had to be amazed by the efficiency of the designers in Xifei.

When Qi Yiming came to Yan Liang's test airfield and saw this magic fighter codenamed "Flying Cloud Leopard" and model J-7B, he had a further understanding of the power of the Red Alert engineers in his heart.

Leopard B looks almost impossible to find any similarities with Leopard A, the appearance is already a standard third-generation aircraft aerodynamic shape, and the concept of conservative has been left behind, and I don't even know which one of the heartless people painted this prototype with a leopard print coating, and it hurts to see Qi Yiming.

The test flight of the prototype went smoothly, and after the Leopard B took off, the landing gear was not retracted and simply made some routine maneuvers in the air, which looked relatively smooth and did not have any major problems. Qi Yiming also felt that this plane was basically something that a group of people put together with mature skills, saying that it was not brand new, and the progress would be relatively fast.

It's just that Qi Yiming didn't expect that there was no difficulty in the technique, but there were new demon moths in other aspects.
