At this time, Wang Bin thought to himself that he must find a way to get the drawings and manufacturing process of the fighter in Donald''s hands, and Wang Bin also looked forward to realizing the manufacturing of the aircraft in his world.

    Moreover, Wang Bin is also looking forward to the performance of the aircraft in his world. After all, in Donald''s world, the aircraft can achieve this level, so in his world! You should know that the overall technology in his world is not comparable to Donald''s world.

    Not to mention anything else, as far as the aircraft engine is concerned, he can be sure that the thrust to weight ratio of Donald''s world engine, even the engine installed on this giant bomber, can never exceed 10, while in Wang Bin''s world, the thrust to weight ratio of jet aircraft engine has reached more than 10, if not 10, So I''m absolutely embarrassed to say that it is the world''s advanced level. Even some engines have a thrust weight ratio of more than 15.

    Therefore, if the aircraft needs 16 engines in Donald''s world, it doesn''t need so many engines in Wang Bin''s world. As long as ten or less engines can reach the combined thrust of all engines of their aircraft.

    Then Wang Bin focused on the performance of these glasses installed on the aircraft. Due to Donald''s attention to the aircraft, the cockpit and engine compartment of the aircraft used more than 8mm glass as protection, especially the engine compartment and fuel tank, with a thickness of 12mm.

    Therefore, the protection of these places is very strong. If they are at an altitude of more than 5000 meters, even large-diameter anti-aircraft guns can not cause damage to the aircraft. After all, large-diameter anti-aircraft guns do not rely on directly hitting the aircraft to shoot down the aircraft, but on fragments after the explosion of artillery shells to destroy the aircraft.

    Not to mention the aircraft, only the titanium alloy skin, titanium alloy skeleton and armor used by the aircraft itself have strong defense against the fragments produced by the projectile. If it is not a short-range explosion, under normal circumstances, the fragments produced by the projectile can not penetrate the titanium alloy skin and armor of the aircraft.

    Now, after the installation of special glass, its protection level is higher. Even if it explodes at a close range, the fragments generated cannot break the glass protection. Even if the aircraft reaches an altitude of more than seven kilometers, it can be directly hit by a 100 caliber anti-aircraft gun. Nor can it cause great damage to the plane.

    Like those aircraft before, this aircraft has participated in bombing missions against the enemy three times since it was manufactured half a month ago. During the mission, the performance of this bomber is quite eye-catching, and even has become a thorn in the flesh of the enemy country.

    In order to deal with the plane, when the bomber was on its third mission, their hostile countries also sent more than 100 fighters to intercept and shoot down the bomber, which posed a great threat to their country, but they failed.

    Not to mention, the maximum speed of this bomber has reached Mach 2.0, which is not what fighters of that era can do. Only the altitude at which this bomber flies during its mission can not be reached by these planes during World War II. Therefore, they not only failed to destroy the bomber, but even lost a large number of fighters under the attack of the bomber escort fighter.

    However, Wang Bin did not see the data of using this glass to install in ships in this U disk. Wang Bin is quite. Maybe this glass has not been installed on ships in their country.

    After all, the total amount of glass he bought from Wang Bin is only six tons. If a small amount is installed on land combat equipment and air combat equipment for testing, the quantity is barely enough.

    However, once installed on the ship, such a small amount of glass is not enough. After all, the tonnage of a warship is often thousands of tons. Even those smaller warships have reached hundreds of tons, so they are not installed on the ship for testing.

    Wang Bin is not sure that after Donald gets the 45 tons of glass this time, they will definitely continue to test the glass, including testing on various ships, even battleships.

    However, it can also be seen from here that Donald''s experience in the science and technology mall has greatly reduced the importance of large surface gunships such as battleships, and began to pay great attention to the development of the air force.

    From these data, we can clearly see that, after all, there were only so many types of wanziguo aircraft in the original World War II, and now the number of aircraft only appearing in this test data has reached more than 20.

    In addition, there are several jet fighters. You know, in the original historical process, jet fighters will not appear first in their country until the end of World War II, but now in the early stage of World War II, their country has developed jet fighters, which have been very mature and even started large-scale equipment.

    Of course, Wang Bin did not pay too much attention to the war in Donald''s world. After all, Donald has the ability to enter the technology mall, coupled with the change of Donald''s national allies.

    Therefore, the process of World War II in their world will certainly be changed. Although their country may not win, it has little chance of failure.

    Moreover, Wang Bin can be sure that Donald''s world and country have begun to develop nuclear weapons, and may even have developed them.

    According to Donald''s previous statement, he has been able to enter the technology Mall for more than ten years. For so many years, Wang Bin does not believe that they will not develop such weapons that can change the war process.

    Soon, Wang Bin finished reading the data, and Wang Bin fell into meditation.

    He was quite satisfied with their performance in Donald''s World War, but the glass was not without defects.

    Although the performance of this glass is excellent, the price of this glass is too high for many people, and so is Donald, so it is doomed that this glass cannot be equipped on a large scale.

    At the same time, Wang Bin is also thinking about the focus of future development in the science and technology mall. After all, he can''t sell everything in the mall in the future, so he should focus on his own situation and develop in a certain direction.

    If they are not sure about their development direction, it will not be good for their Tiangong technology, and it may even lead to problems in their Tiangong technology.
