Recently, college students made their own solid rocket
The successful video is on fire
At present, the video has played more than one million
There are more than 6000 bullet screens
It’s shown in the video
A rocket from independent design
To fluid simulation, manufacturing, testing, control
And the whole process of final launch and recovery
“A cloud piercing arrow, thousands of troops will meet”
The screen of netizens is on
In the video
A cool rocket with transparent body
Standing in a field waiting to be launched
“The countdown begins
