This unexpected take-off made everyone shout wonderful! They were all so excited that they shed tears, this was an epoch-making first flight. Not only that, but it was the designers who flew the first jet plane in human history! How much does this stake? Everyone knows very well in their hearts that the M29 competitive jet is a jet that has never been to the sky, and everyone is sweating for Xiao Weiguo in their hearts.

But Xiao Weiguo, who flew into the blue sky, was not so nervous! Now he feels like the M29 Competitive Aircraft was born to fly! Under the strong thrust of the wind and thunder jet engine, the M29 racing aircraft is like a sharp arrow straight into the blue sky! In the entire factory area of Dragon Soul Aircraft Manufacturing Co., Ltd., the roar of the wind and thunder jet engine can be heard, because Xiao Weiguo adjusted the thrust of the engine to the maximum when taking off! Now the plane is climbing at a very fast speed, and the jet is indeed much faster than the propeller plane!

This can not only be seen from the ground, but Xiao Weiguo, who is piloting the aircraft, can also clearly feel that the speed and climb rate of the aircraft are constantly rising! As you can see from the dashboard, as soon as the M29 Competitive Jet leaves the ground, its speed rises rapidly, soon exceeding 400 km/h, then 500 km/h, and so on, reaching 800 km/h in a few minutes! The world record for flight speed was born!

Not only that, but the M29 Competitive Jet has an amazing rate of climb! It took only 3 minutes to climb to an altitude of 5,000 meters, and at this time it was almost invisible to people on the ground, and although the weather was nice and cloudless, it was just a small black dot!

After 5 minutes. The M29 competition jet climbed to an altitude of 10,000 meters under the control of Xiao Weiguo, which is another world record broken! The climb rate of the aircraft reached more than 30 meters per second, which is an amazing statistic! In fact, if you don't count the take-off time, the M29 competition jet has a climb rate of more than 40 meters per second. This is definitely breaking the world record, and the flight altitude of 10,000 meters is a flight altitude that propeller aircraft can only look up to and sigh!

Looking out from the cockpit, there is a clear blue sky overhead, which is really beautiful! Xiao Weiguo sighed, but he didn't stop, and continued to maneuver the plane to climb up, because the M29 competitive aircraft was designed to fly at an altitude of 15,000 meters! Xiao Weiguo carefully maneuvered the plane while staring at the altimeter where the pointer was flying like the blades of an electric fan. 11,000 meters, 12,000 meters, 13,000 meters...... This time, in less than two minutes, the height reached the designed 15,000 meters! The first test flight reached the designed indicators, which is absolutely amazing, and no one dares to do this in general! However, Xiao Weiguo has great confidence in this aircraft!

Moreover, he was also ready to fly as fast as this plane could be. After all, at high altitudes, the advantages of jet engines are even more obvious, and the flight resistance at high altitudes is very small, and it is easy to reach the fastest flight speed. It is even possible to reach the sound barrier! However, Xiao Weiguo did not dare to hit the invisible wall, which was very dangerous for the M29 competitive aircraft!

If not the design of a supersonic aircraft. When the flight speed of the aircraft reaches the speed of sound, it is very likely that the phenomenon of disintegration in the air will occur, resulting in the tragedy of the plane being destroyed and people killed. The main culprit preventing humans from exceeding the speed of sound is the atmosphere. Under certain conditions, air can form extremely strong "walls", and even extremely hard steel can shatter if it hits this wall. Similar to the vibration of an object in the air. When all objects move in one direction in the air, the air in the direction of the object will be compressed, and the faster the object moves, the more the air in front of it will be compressed, and eventually a very dense "compressed air layer" will be formed. This is the "wall of air".

Although the M29 competitive aircraft is basically designed according to the first-generation jet aircraft J-5 and J-5, and the J-5 aircraft is also capable of supersonic flight, it is obviously impossible to fly at supersonic speed in the first test flight, unless the test pilot is a madman!

The first generation jet MiG-15 is an example of this! Due to aerodynamic deficiencies, the MiG-15 suffers from wing detachment and other effects when passing through the sound barrier, which significantly affects its ability to use. Another disadvantage of the MiG-15 is that it is prone to tailspin in motion. And experiments have confirmed that even with a more powerful engine, the MiG-15 still cannot reach supersonic speed, due to the lack of sweep angles of the wing! Later, after refinement and the drop of several test aircraft, the MiG-15 was barely able to fly faster than the speed of sound, that is, it could reach a speed of Mach 1.14 only when flying in a dive.

However, the M29 competitive jet has a aerodynamic shape closer to the strong five, so it is still possible to achieve supersonic flight if the engine thrust is sufficient, but with the current thunderstorm jet engine, it is still slightly insufficient to achieve supersonic flight thrust.

Xiao Weiguo maneuvered the plane to change to level flight, and now the cruising altitude has reached 15,000 meters, and the cruising speed under the continuous maximum thrust has also reached 900 kilometers per hour! Xiao Weiguo remembers that during World War II, the German fighter "BF-109" was modified several times, increased engine power and weapons, and set a world record of 755 kilometers per hour in 1939, which has not been broken for a long time. But now this record will be rewritten, in this time and space in 1933, the M29 competitive jet reached a cruising speed of 900 kilometers per hour in its first flight, and Xiao Weiguo will break this speed!

The maximum speed of an aircraft with a piston engine and propeller was only 850 km/h, and that was in 1989. During World War II, the maximum speed of piston propeller aircraft did not exceed 800 kilometers per hour. In 1940, North American Airlines developed the P-51 "Mustang" fighter. It uses an advanced fuselage and airfoil, and the aerodynamic drag is greatly reduced. Its modified version of the P-51D had a maximum speed of 785 km/h. During World War II, German aircraft designer Dornier developed the Do-335 "Arrow" fighter, which also reached a top speed of 785 km/h.

Xiao Weiguo decisively increased the engine speed to 10,000 rpm, and at this speed, the thrust of the wind and thunder jet engine increased again, reaching the maximum state, that is, 2,060 kg! At this time, the fuselage of the plane also began to tremble violently, the pointer on the speed dashboard deflected again, and the most tense moment came! (To be continued.) )
