Chapter 458 (1/2)

With the permission of the tower, Phoenix No. 1 took the lead in taxiing on the runway, and soon looked up and took off, followed by the take-off of No. 2.

After plane 2 took off, Guo Lin also slowly increased the fuel supply of the plane to the maximum, and the plane naturally began to accelerate rapidly under Guo Lin's operation. It was not until about 3000 meters that Guo Lin pulled up the plane and flew at the previously calculated angle, that is, the angle of ten degrees upward.

And when the engine is put on, he always drives at the maximum, and does not reduce the output power of the aircraft due to the take-off of the aircraft.

In less than a minute, the speed of the plane has more than doubled the speed of sound, and the speed is still improving.

Of course, this is not just his plane. Looking out from the glass of the plane, he can clearly see that not far from his left, there are two phoenix kt1 aerospace aircraft flying rapidly at the same angle.

Soon, the speed of the aircraft reached Mach 2.5. At this time, he can clearly see that there are red air currents on the two aircraft not far from him, especially on the head and bottom of the aircraft. With the increase of the aircraft speed, these red air currents finally become a red air mass centered on the aircraft, And the figure of the plane gradually disappeared in his figure.

Seeing this, Guo Lin was not worried, because he clearly knew that this was the normal situation after the aircraft and the atmosphere rubbed after the speed exceeded Mach 4.

Even when he looked out in the plane, he could clearly see that the red air flow flowed in front of the scale of the plane.

”Please note that we are about to reach an altitude of more than 45000 meters. At that time, due to the low oxygen content in the atmosphere, the aircraft engine will not work, so wait a minute. After the aircraft engine stops working, change the engine working mode manually?” Zhao Feng's voice came from the aircraft's communication system.

”Yes, Captain!” in fact, he has mastered the theoretical knowledge for a long time, but he has not carried out the actual operation yet.

Moreover, he really, this aircraft also has an automatic operation system, that is, as long as he inputs the orbital altitude data he wants to reach, such as perigee and apogee, the aircraft can fly automatically and reach the corresponding altitude.

However, as a novice, Tiangong technology requires that the automatic driving mode cannot be used without permission, that is, before being proficient in the manual driving mode.

Therefore, when the altitude of his plane reached nearly 50000 meters, the engine of his plane finally stopped working due to insufficient oxygen.

So he immediately manually turned on the rocket engine mode of the engine and restarted the engine.

However, just as his space plane had just broken through the atmosphere and reached an altitude of 100000 meters, that is, 100 kilometers, he suddenly heard a sound of touch and the feeling of aircraft vibration, which made him nervous at once.

Obviously, the sound and vibration just now all indicate that the plane has just been hit by something, and the impact force is not small.
