In Yang Tianfeng's view, the only advantage of these two Su-series aircraft is the air-cooled engine of the Wright r-1820 series.

Combined with the extremely light fuselage mass of wooden aircraft, first-class mechanical supercharger, advanced laminar flow wing shape, scientific and advanced fuselage design, two-blade propeller to three-blade, and 12.7mm heavy machine gun equipped with explosive bombs and burning bombs, it is a fighter that can compete with active Japanese fighters and have an advantage in many aspects.

"Although the few test flights under him did not reach the limit, I felt that the flight speed and dive speed had been greatly improved." Han Zhen described to Yang Tianfeng, "It seems that there is no improvement in horizontal maneuvering at medium and low altitudes. Is it because the weight has been increased too much in order to strengthen the wings and fuselage?"

Nonsense! I'm targeted design, using better glue, supplemented by some aluminum alloy of the original aircraft, strengthening the strength of the wings and fuselage, specifically to resist Zero fighter jets.

If you have a fast speed, you will be right when you dive quickly. If you fight, you will run away! Whoever fights against zero battles in the middle and low altitude is the brain that will be funny.

Yang Tianfeng thought so in his heart, but said, "Although wooden aircraft have some advantages in lightness, fast speed is a greater advantage. When the second-level two-speed supercharger is successfully manufactured, the high-speed performance of the aircraft will be improved."

"The speed and vertical maneuverability of the Yi 16 are quite good. Compared with the Japanese Type 96 and Type 97, it is only slightly worse at most." Zheng Shaoyu, the newly arrived one, said: "In my opinion, what we need to strengthen is the horizontal hovering ability."

Zheng Shaoyu is a veteran pilot with a lot of practical experience. He has shot down the Japanese Type 96 fighter jet and was also injured by the Japanese fighter jet. He made a judgment based on his own experience. Of course, because the aircraft is heavier and poor low-speed horizontal hovering ability, it is indeed the weakness of the Iran 16.

"Well, this is a level-based fight, and it will not be the mainstream of the world's fighter jet development in the future." Yang Tianfeng said in a silence: "Our tactics must also be based on speed. The tactics of running after fighting are not only very smart, but also suitable for the current situation of our country with a low level of aviation industry. We will strive for the greatest victory with the smallest loss!"

Liu Zhihan laughed at the side, and there was also a sneer. He was also a pilot with achievements. He thought Yang Tianfeng was an amateur and even said that his level of fighting was outdated.

Yang Tianfeng looked sharp and saw it. He couldn't help but roll his eyes and sneered: "Don't think that he had any achievements in attacking and shooting sunsets, so he didn't want to make progress. The Japanese have only a few types of aircraft, and they can't develop new fighter jets? Can my country's aircraft production capacity be compared with Japan? There are a lot of aircraft purchased from a lot of money, but now there are still many left, can they resist the number of Japanese aircraft advantages? If you don't fight smarter, isn't there any problem with your brain?"

Liu Zhihan opened his mouth, but could not say any reason to refute, and quickly corrected the expression on his face.

"The improved aircraft has improved manoeuvre, speed, vertical maneuver, and even horizontal maneuver, which is improved compared to the original one." Yang Tianfeng pointed to the fighter jet that rushed out of the mountainous area. "Since there has been improvement, why not improve? Use assault means to compete with Japanese aircraft, which not only achieves results but also reduces losses, but why not use them? I feel that I am an expert and a veteran in flight, so why don't I use old aircraft to fight against Japanese aircraft?"

"The military throne was joking." Han Zhen was trying to smooth things over, smiling and changing the topic, "Well, that Japanese are really developing new aircraft?"

Yang Tianfeng hesitated for a moment, feeling that the Zero fighter jet would fly to China in another three or four months. It would be no harm to say it in advance, so he slowly said: "According to information, the new fighter jet developed by the Japanese will soon be put into the Chinese battlefield. Because the range of the 96 and 97 is not enough, the main purpose of this new fighter jet is to carry out escort missions for bombing the rear."

Speaking of the 96th and 97th-style range, this is more professional. Zheng Shaoyu thought it was reliable, so he asked tentatively: "What is the name of this new fighter? What are the advantages of apart from the range?"

Yang Tianfeng grinned and said, "Called by Lingdaner." After everyone's laughter stopped, he pressed his hands down before saying solemnly: "In addition to the super-large range, this aircraft has a horsepower of nearly 1,000, and is extremely excellent in both climbing and maneuverability. From an intelligence analysis, Lingdaner is currently one of the best fighters in the world. Compared with it, Yi15 and Yi16 have no power to fight."

"So amazing?" Liu Zhihan made a shocking voice, and also expressed his disbelief.

Yang Tianfeng looked at him, sighed, and said, "You will know how powerful it is. If you are willing to be humble, master the modified new fighter jets, use new tactics, play to your strengths and avoid your weaknesses, you will not be beaten to hide from all over the world, and you can only watch the Japanese planes rage and watch our country's military and civilians be bombed and fired. I think, as the air force, you enjoy high treatment but cannot repay the country and the people, that is probably the greatest shame, right?"

"General Yang, my subordinates understand." Zheng Shaoyu lowered his head solemnly.

Liu Zhihan let out a long breath, nodded vigorously, turned his gaze to the new plane flying in the air and making maneuverable movements.

The aviation industry in the border area started late, and only with Yang Tianfeng's knowledge, he made up several aircraft. The bottleneck of large-scale production is engines, and engines with different varieties, models, shapes and powers also restrict the large-scale production and manufacturing of aircraft.

Therefore, Yang Tianfeng fell in love with the largest number of Soviet fighter jets in the National Army Air Force. The unified engine is quite favorable for large-scale modification. It is not only to strengthen the strength to fight against the Japanese, but also to save the lives of innocent people in the rear.

At the same time, Yang Tianfeng's modification is profitable. One or two of them can be left to change the ten aircraft, and the government can apply for talent transfer and application funds for modification, which can further improve the level of aircraft manufacturing in the border areas.

Instead of waiting until the Zero is driven to China, shooting down hundreds of National Army aircraft and controlling the entire sky, it is better to modify those already lagging behind and then conduct targeted training on the weaknesses of the Zero. Even if the Zero cannot be defeated, the losses can be reduced. Then use the radar warning and dispatch at the right time, and can still fire Japanese aircraft without any warning.

After three improvements, the plane made more and more difficult movements in the air, and occasionally passed by high speed over the playground, attracting bursts of cheers and noise.

After the finalization, three more aircraft will be modified. Then these four fighter jets will be trained in adaptive flight and dual-plane marshalling by Zheng Shaoyu and others, and will not return to the rear after about two or three months. If the State Government trusts Yang Tianfeng and Zheng Shaoyu and others' evaluation report, the modification of the aircraft can be carried out continuously, and it is a task that can be completed every month. By July and August, more than 20 aircraft with near-zero performance will be enriched into the National Army's Air Force.

Close is not enough to withstand the Zero, but in addition to aircraft performance, air combat also has coordination and tactics. For example, the Flying Tigers are flying Mustang P-40b, which is not as maneuverable as the Zero, but relying on the advantage of fast dive speed, they adopt the tactic of high-speed dive and running after fighting to avoid entanglement with the Zero, and also achieves a very good record and has a small loss.

"It is reported that the Japanese Zero Daner fighter is loaded with 20mm cannons, and its firepower is very strong." Yang Tianfeng has become accustomed to using these words "it is reported" and "maybe". Only those who know him know what he said will most likely be true. "But the performance of the cannon is not good enough, and too much pursuit of the light weight of the plane leads to insufficient strength. The effective range of the cannon is short, the ballistic bends and scatters, and even the firing ability is poor, and there are only sixty rounds of ammunition. The point 50 heavy machine guns equipped on our planes must exceed their cannons in terms of range and ballistics, and the power of special ammunition is greater than that of Zero Daner."

This time, Liu Zhihan made a record honestly. Yang Tianfeng was very clear-headed, and he believed that this was true.

"If you are rear-ended by Zero Egg, you must take a rapid dive to escape. Remember to dive to maneuver to the left and never to the right." Yang Tianfeng continued to talk about the weakness of Zero Egg, "Remember not to use climbing methods to get rid of it, nor do you pursue Zero Egg that has sharply climbed. Zero Egg has excellent climbing rate and turning radius, but the dive speed is its disadvantage, and its movement performance will be severely reduced at high speed. Therefore, when fighting with Zero Egg, the speed is the most important. You must maintain a high speed and never engage in low-speed battles, that is purely a search for death."

After saying that, Yang Tianfeng pointed to Liu Zhihan and others and said, "I have sorted these things into materials. You don't need to record them. You can also study them carefully afterwards. Although the Chinese Air Force is weak, as long as you persist for another two years, it will inevitably make great changes as the situation changes. You have a long way to go!"

…………………

In early 1940, on the day the Wang puppet regime was announced, the US government took the lead in issuing a solemn statement that it would not recognize and announced that it would provide a loan of $20 million to the Kuomintang government.

As early as July 1939, the United States adopted economic sanctions against Japan and abolished the "US-Japan Trade Treaty"; since September, the scope of the United States' "moral embargo" against Japan has gradually expanded, which was also a major blow to Japan. At that time, the import volume from the United States accounted for nearly half of its total overseas imports, and its bulk strategic materials were imported from the United States.

In Yunxiu Tower, Chongqing, Chairman Jiang had just held an internal meeting, and his tone changed drastically. The negotiations with Japan held in Hong Kong as Song Ziliang not only increased the price, but also strengthened the price.

In Chairman Chiang's view, conflict between the United States and Japan is inevitable, and the United States' actions are undoubtedly an economic declaration of war against Japan. The international environment of China's war of resistance is improving, and the situation of Chinese military and civilians fighting alone is also reversed.

Yang Tianfeng's predictions were fulfilled one by one, which made Chairman Jiang pay more attention to it and basically believed in the background behind him. The international situation prediction that Yang Tianfeng just sent naturally made him care more and analyze and study it more carefully with his think tank.

"The definition of aiding China to control Japan is very accurate." Chen Bulei nodded in appreciation, "Aiding China is to enhance China's ability to further resist Japan and help China become a place to constantly entangle Japan and consume Japanese power; the control of Japan is to create some difficulties for Japanese aggression forces in terms of arms material. But the upper limit of this policy is to avoid a head-on conflict with Japan, and to gain time for the United States to prepare for the two oceans to fight at the same time."

"In other words, the United States will not go to war with Japan in the short term." Chairman Jiang frowned.

Chen Bulei pondered for a moment and said, "The United States' aid to the United Kingdom is generous, which also verifies Yang Tianfeng's strategic policy of the US government's 'first Europe and then Asia'. In this case, Yang Tianfeng's concern is that the United States is appeased and compromised to Japan in order to avoid conflicts with Japan in the Far East as much as possible."

Chairman Jiang was speechless for a while, thinking for a while before speaking: "The United States has approved the loan, and from an attitude, there seems to be no need to worry too much. Of course, necessary work and preparations must be done. For example, use the loan to rush to buy a batch of urgently needed strategic materials and transport them back from the Yunnan-Burma International Transportation Line."

Chen Bulei nodded and suggested: "In addition to loans, donations from overseas Chinese in Southeast Asia can also be made more use of."

Speaking of the donations from overseas Chinese in Southeast Asia, Chairman Jiang couldn't help but smile bitterly and said, "I have sent a telegram to Wei Junru of War Zone and Yang Tianfeng of Shandong-Yuan Border Region, asking them to entertain Chen Jiageng and his party well, hoping to reverse Chen's bad impression of the country's government."

In the spring of 1940, Chen JG, a patriotic overseas Chinese leader living in Singapore, led a delegation back to the motherland to comfort the anti-Japanese military and civilians with the earnest instructions of the vast number of overseas Chinese in Nanyang. The first stop was of course Chongqing, the capital of wartime. Chairman Jiang attached great importance to it and ordered that the reception work be done at all costs and to satisfy the guests. However, his request achieved the opposite effect.

Mr. Chen Jg is a patriotic old overseas Chinese from the Tongmenghui. After the beginning of the War of Resistance Against Japan, as the chairman of the "Nanyang Overseas Chinese Association", he was responsible for the work of overseas Chinese in the entire Southeast Asian region to support the motherland's war of resistance. Under his organizational leadership, the majority of overseas Chinese donated money and materials to the country every month. Over the past three years, the majority of overseas Chinese have raised about 400 million "national coins" for the motherland through the Federation, with countless supplies.

After the lifeline of the Anti-Japanese War, the Yunnan-Burma Highway was completed, drivers and repairmen were in short supply. Chen JG climbed the high school and called out, and more than 3,000 young overseas Chinese bid farewell to their relatives, braved the enemy's artillery fire, and kept transporting military supplies day and night. It can be said that without Chen JG and the vast number of overseas Chinese, the victory of the Anti-Japanese War would definitely be postponed.

In accordance with the spirit of Chairman Jiang's instructions, the National Government established a welcome committee with a huge lineup, consisting of more than 20 important party, government and military departments, including the Central Propaganda Department, the Ministry of Finance, and the Overseas Chinese Affairs Commission.

In the case of extremely tight finance, sufficient reception funds were also paid, of which the banquet alone was 80,000 yuan. At that time, the money could buy 800 cows!

In this way, Chen JG had no time to do his job during his days in Chongqing and was forced to run around in various banquets every day. But no matter what delicacies were, Chen JG could not swallow it in one mouthful.
Chapter completed!
