However, at this time, after receiving the report from Zhang Feng, both Wang Bin, Professor Pao and general Qiu looked very nervous and stared at the radar screen.


    However, at this time, Zhao Feng''s altitude is still about 10000 meters, and the speed is also maintained at twice the speed of sound. Therefore, if it is operated properly, even if the fighter has no oil, it can glide over the base for landing, but when the aircraft has no oil at all, landing is not a small danger.


    Time passed minute by minute while Wang Bin and others were waiting like a year. While Wang Bin and others were waiting anxiously, a faint roar of aircraft came over the base. Hearing this sound, Wang Bin and others immediately realized that the fighter plane driven by Zhao Feng was coming back.


    So everyone immediately raised their heads and looked into the air. In the control in the distance, a white dot was flying towards their base. Of course, Wang Bin and they knew that the white dot was the seventh master driven by Zhao Feng.


    However, at this time, the aircraft was still roaring. It was obvious that his aircraft engine had not stopped and there was oil.


    But just as they were relieved, suddenly the rumbling sound from the distance disappeared.


    "Report to the tower that the fighter has run out of fuel. Now it is ten kilometers away from the base. The fighter has an altitude of 8000 meters and a speed of Mach 0.9..." at this time, Zhao Feng''s voice came again from the horn of the tower.


    "Keep heading..." hearing Zhao Feng''s report, the tower immediately commanded Zhao Feng to glide his fighter plane towards the base, immediately ordered personnel to clear all personnel on the runway and fighters waiting for take-off training, and also made various support and rescue equipment ready for rescue immediately.


    As the plane gets closer and closer to the base, finally, the plane adjusts its attitude and rushes towards the runway, and Wang Bin and others are worried about it. After all, when the plane loses power, as long as Zhang Feng''s operation deviates a little, the landing will fail, and the consequences of failure are naturally very serious, That''s machine destruction and human death.


    Fortunately, Zhao Feng is worthy of being an excellent pilot in China. Finally, Zhao Feng landed steadily on the runway, and Wang Bin and others were finally relieved. At the same time, everyone was very happy.


    When the plane stopped steadily on the runway, Wang Bin, Professor Cha and others immediately stepped out of the tower and came to the side of the Qiye fighter that had just passed the test flight, and the base staff who had been here for a long time to find the cause of the aircraft failure. Of course, Professor Cha and others checked the engine of the aircraft, The ground service and technical personnel of the base inspected the body and internal structure of the seven master.


    Fortunately, the cause of the problem was not difficult to find. Soon, the flight crew of the base found the problem not far from the tip of the left wing.


    So everyone immediately went forward to observe the cause of the accident. It turned out that a small piece of skin in the middle of the wing mailbox was broken not far from the wing tip of the seventh master, which led to the fuel leakage of the aircraft.


    Seeing this, in fact, Wang Bin and Professor Zhang are very clear about why this seventh master has such a problem.


    Because at the beginning of the seventh master''s design, its limit speed and height were only double 2 standards, that is, the limit speed was Mach 2 and the limit height was 20000 meters.


    But what about this test flight? During this ten, the seventh master flew to an altitude of 30000 meters, and even its speed reached Mach 3 and a little higher, which has far exceeded the limit of the seventh master''s design. Even the seventh master in front of Wang Bin has undergone a lot of transformation to make his character stronger in all aspects, but like today, It is also beyond the limit that the seventh master can bear.


    Find out the problem. Whether it''s Wang Bin or professor poke, their hanging hearts are finally relieved. After all, their engine performed very well during the off-site test flight.


    "Hello, officers! Zhao Feng successfully completed the flight test mission and successfully completed various flight test subjects. Please give instructions." just after Wang Bin and others found the problem, Zhao Feng climbed out of the cockpit and saluted general Qiu.


    General Qiu also saluted Zhao Feng and said, "well, Comrade Zhao Feng, thanks to your efforts, you have successfully saved the fighter for the test flight. I will report the matter to my superiors and ask for credit for you."


    "Thank you, sir, but as a pilot, I think any good pilot will do so," Zhang Feng said.


    General Qiu nodded with satisfaction.


    "By the way, major Zhao, I don''t know if you have any opinions about the engine of this aircraft during the flight? If so, please say it and we Tiangong technology will find a way to solve it." after general Qiu and Zhao Feng talked, Professor Zhang, as the developer of this engine, asked Zhao Feng. At the same time, Wang Bin also took out his notebook, Ready to solve the problem Zhao Feng said yes.


    "Professor Zhang, I feel very good about this engine during the flight test, and its stability is also very good..." then, Zhao Feng said the same thing he felt during the flight. Even after saying that, he didn''t forget to praise this engine, And hope to equip this engine with these main fighters in their base.


    He believes that as long as these main aircraft in their base are equipped with this engine, even if they encounter more advanced fighters than their fighters, they will definitely be able to compete with them.


    For what Zhao Feng said, I hope this engine can be installed on these main fighters in their base as soon as possible. Whether it is Wang Bin, Professor Pao and general Qiu, they just smiled and didn''t answer. After all, let''s not say first, Wang Bin''s engine is still in the verification stage of various performance, or it still doesn''t meet the standard of being really equipped on the main fighters, Only in terms of production capacity, it has limited the time of this engine, and it is impossible to replace all the engines of these main engines in the base on a large scale.


    Not to mention, this matter is not up to Wang Bin, Professor Zhang and general Qiu. It depends on the arrangement of the superior. Moreover, Wang Bin and their engine have not even obtained the production license, so they can''t give Zhao Feng a satisfactory answer at all.


    However, general Qiu said, "Mr. Wang, I am also very powerful for such an excellent engine. After all, as long as our main engine can be replaced with this engine, it can definitely add wings to the tiger and greatly improve the combat effectiveness. I will respond to the superior about the test flight results."


    "Thank you, general Qiu. At the same time, Tiangong technology will try its best to improve the performance of this engine and make it more excellent." Wang Bin said happily to general Qiu.
