China is preparing to send troops to Syria and Iraq to participate in the war on terror, and to be honest, the Internet is almost half in favor and against. After all, Syria is too far away, and China has no overseas bases, so sending troops from afar is a huge burden on logistics and finances. At the beginning, the Iraq war dragged on the United States for so many years, and the large military spending made the United States, a superpower, almost overwhelmed, and ISIS, which used the Syrian civil war to completely turn the tables, is an incomparably huge pit.

ISIS not only occupied part of Syria, but also part of Iraq, and finally declared the establishment of a state, and like a serious company, it dared to publish an annual report to the international community. In the 2013 annual report, ISIS launched 10,000 operations in Iraq alone, including 1,000 assassinations, 4,000 bomb planting, prison robberies and massacres, etc., and what is even more incredible is that ISIS actually posted recruitment advertisements on its website, such as "There is a good salary here, you don't have to do much, and you can eat and live" and so on, and even the famous social media 'Facebook', there are dolls sold by ISIS.

ISIS has gradually grown and grown, not only has all kinds of light weapons, such as AK47, M4, M16, grenades and Soviet-made 12.7mm heavy machine guns, etc., but also has heavy equipment such as tanks and armored vehicles, and the most exaggerated thing is that ISIS has actually established an air force. Although ISIS only captured a few second-generation aircraft such as MiG-21 and MiG-23 from the Syrian government army, they are also fighter jets, and there are some with missiles.

All in all, ISIS is a pit, a huge pit, although ISIS has included Xinjiang in their future "territory" and has positive ties with the East Turkistan terrorist organization, but China has not responded positively to the United States' invitation to join the so-called "international coalition" to fight terrorists, only saying that in the aspect of counterterrorism, China will give firm political support, economic supply and even intelligence exchange, but China has never expressed its position on the issue of sending combat troops.

The leadership naturally has its own considerations, and sending combat troops to Syria to participate in war operations will cause a great burden on domestic logistics and economy, and although the purpose of military training can be achieved, after all, it is a war act led by the United States, and there are still some domestic concerns. Moreover, once the combat troops are sent to participate in the war, it means that the international image of China's old good man will be changed, and the pros and cons will not only be economic, but will have an unpredictable impact on the entire international and domestic environment.

The country promised to send troops to participate in the operation this time, but what kind of troops to send, what kind of tasks to perform, there is no clear attitude, and there is no such swiftness and decisiveness as the raid on southern Tibet, what to do in the future, more consultations are needed, this kind of intrigue between countries is not a matter of a few people, but a choice made by concentrating the wisdom of the country, so Xia Yu actually doesn't care much about these things, according to Xia Yu's words, that is, if you are not in your position, you don't seek politics, and it is good to know some things, Spend too much time guessing the things on the political zhì, it's better to spend some energy doing what you want to do, it's not as good as the current X20.

After the assembly of the first test machine of the X20, it is necessary to conduct ground tests of up to thousands of projects, because it is an independent development plan in the J-20B, so the X20 will not be like the J-20 at the beginning, more than a dozen prototypes and verification machines were built to do testing, and the resources provided by Chengfei to the X20 allow Xia Yu to only have a static testing machine, a prototype and a verification machine.

Among them, the static testing machine is only tested on the ground, and after the fatigue test is finally done, it is basically scrapped, and it is impossible to participate in the test flight of lift-off. The prototype is the first batch of aircraft built according to the design drawings, usually several planes are built in succession, and then according to the number of prototypes obtained after the flight, several of them are used to make modifications. However, due to the lack of resources, it is impossible to make more than one prototype of the X20, so Xia Yu will not use the prototype to fly until it is confirmed that a certain technology is successful, and the demonstrator is the aircraft that will perform the most surgeries.

Among the two prototypes for Xia Yu, the aircraft used as a verification aircraft, in addition to the appearance design is exactly the same as the X20 prototype, the internal structure is basically born from the J-20B, which is relatively conservative compared to the X20 prototype.

In addition to the overhauled WS15, the basic avionics, radar, flight control and other systems are the way of the J-20B, Xia Yu needs to test the same, and finally confirm that there is no problem, and then test the prototype, before that, the verification machine is where Xia Yu needs to focus his energy, just like now.

After the ground test is passed, the X20 technical verification machine can finally start its first flight, Xia Yu sat in the cockpit, and after cooperating with the ground technicians to do the test, he began to control the aircraft from the tarmac to the runway to taxi over, X20's new engine thrust-to-weight ratio is very high, the same power control, the feeling of taxiing is much lighter than J-20A, Xia Yu nodded, the values in the cockpit are normal, and then after starting the other engine, this is focused on taxiing towards the runway.

In the past ten years, because the J-10, J-20 and other national cutting-edge fighters have been designed, manufactured and tested from here, coupled with the application of satellite technology, the country has also consciously publicized the strength of military science and technology, so the level of secrecy is not as good as before. This also attracted a lot of military enthusiasts to run to the test flight site to watch, after a few people to see the hidden fighters with their own eyes, and even some enthusiasts as long as they are free, they will squat outside the wall of the test flight site, waiting for the plane that does not know when it will be tested once.

Among them, Huang Mingyuan is an avid fighter enthusiast, J-10 and J-20 are as many as he treasures, in Huang Mingyuan's eyes, J-20 since the WS15, except for the engine thrust is still inferior to the F22 Pratt & Whitney F119, other things are not afraid of F22 at all.

The advantage of being a latecomer makes the J-20 ahead of the F22 in the airborne system, slightly weaker than the F35, there is no doubt that for Huang Mingyuan, the J-20 is not afraid of any opponent if it is heads-up, and it is the most powerful fourth-generation fighter in Huang Mingyuan's heart. Since the news of the development of the J-20B came out, in order to get a sneak peek, Huang Mingyuan will run to the outside of Chengfei's test flight as long as he has time, looking forward to the J-20B upgraded from the J-20A, and wondering what has changed.

Huang Mingyuan, who had been waiting outside the wall of the test flight site, did not expect that when he thought that today would be the same as usual, he would not be able to wait for anything, a plane with black and gray livery that looked like J-20 was towed outside the tarmac by a tractor to prepare for ground inspection. Quickly picked up the telescope he had prepared and looked at the tarmac, and Huang Mingyuan was directly stunned on the spot. The shape of this aircraft is almost beyond Huang Mingyuan's imagination.

First of all, the most obvious is the cockpit, which is fundamentally different from the previous blister cockpit, Huang Mingyuan found that the entire cockpit has moved down significantly, and the gold-coated glass cover is actually streamlined and naturally extends to the back of the fuselage, that is to say, the pilot can't see the back of the plane at all, which is greatly beyond Huang Mingyuan's expectations, because if the pilot is not equipped with a helmet display system, the cockpit cannot be designed like this.

F35Because it is also a helmet display, the cockpit cover design has actually greatly reduced the pilot's rearview vision, but it still has not departed from the blister-like design, I didn't expect the design of the J-20B to be so advanced, which made Huang Mingyuan's heart can't help but be hot.

As a senior enthusiast, Huang Mingyuan naturally knows that this streamlined cockpit design compared with the blister cockpit, the advantages in aerodynamics are simply incomparable, although I don't know what the specific number will be improved, but Huang Mingyuan can't wait to see what other exciting designs this aircraft has.

PS: Although I understand the mood of the brothers urging the change, however, the sentence with the word 'but' is generally added, and everyone knows that it is swollen ^_^
