Chapter 1071 (2/2)

At a distance of about 200 km near the ground, the spacecraft again adjusted its flight attitude with the help of the auxiliary variable direction engine, pointed the direction of the ion engine towards the earth again, and began to adjust the power of the engine, and began to slow down the spacecraft.

Because the spacecraft also uses the arc orbit to fly back, when the height of the spacecraft falls to about 100 kilometers from the ground, the flight speed of the spacecraft has successfully dropped to 3.5 kilometers per second after the deceleration operation of nearly 200 kilometers of arc flight range.

And entering the atmosphere at a speed of more than 10 times the speed of sound is basically stable for the spacecraft made of the company's most advanced high-performance materials!

However, this speed is still a little high for returning to the ground. After reaching this altitude, the work of ion engine is successfully completed. After the pilot turns off them, six high thrust fuel engines are started again.

Under their strong thrust, the spacecraft continued to maintain this speed and flew toward the direction of the ground base. Of course, during this flight, the power of the engine was constantly reduced. Especially after entering the stratosphere about 50 km from the ground, the two engines were shut down directly under the pilot's operation.

After re entering the dense atmosphere, the wings and perfect aerodynamic shape of the spacecraft played a role again. The speed of the spacecraft was adjusted to 300 meters per second at an altitude of 8 kilometers from the base.

At this stage, everyone is inevitably nervous, because the most critical step of the return flight is coming. Whether the test flight mission can be successfully completed depends on whether the spacecraft can successfully complete the runway landing.

Before the human has never landed a huge aircraft weighing more than 10000 tons, although it has successfully completed 100 landing times in the simulation flight, the four pilots can not help but feel a little nervous at this time.However, the strict training and good psychological quality made them concentrate on the final landing work. Under the guidance of the staff of the intelligent control system and flight control center, they began to adjust the flight speed and angle of the spacecraft.

After adjusting the spacecraft to its best condition, the final step is coming. After aiming at the runway, a total of 60 huge wheels on the six landing gears begin to contact the runway!

With the huge roar when the wheels and the runway contact, under the operation of the spacecraft intelligent control system, the four giant deceleration umbrellas thrown from the tail of the spacecraft provide greater deceleration for the spacecraft.

Let the giant successfully land on the No.2 metal runway. When there is still about 400 meters away from the end of the 4000 meter long runway, the spacecraft successfully enters the static state. At this step, it represents the successful landing of the spacecraft!

Even if Lei Tiantang had already known that the performance of the spaceship was enough to complete all the flight test work, he was in a good mood to see this big guy successfully complete the landing. This is the result of the efforts of the company's people. It's different from his own spaceship!
