[China’s first 10-kilometer-class vertical take-off and landing flight test of a reusable carrier rocket was a complete success]

On June 23rd 2024, China’s first 10-kilometer-class vertical take-off and landing flight test of a reusable carrier rocket was a complete success. The rocket was developed by the Eighth Academy of China Aerospace Science and Technology Corporation.

 At about 1300 hours Beijing Time, at the Jiuquan Satellite Launch Center, Inner Mongolia, China, People’s Republic of China , a 3.8-meter-diameter reusable carrier rocket new technology verification arrow was erected on the launch pad. Three variable thrust liquid oxygen-methane engines were ignited, spewing blue tail flames. The rocket body rose to an altitude of about 12 kilometers. The central engine adjusted the thrust, and the rocket descended in a controlled manner. At 50 meters from the ground, the four landing legs unfolded, and then the rocket slowly descended, approaching zero altitude, and landed steadily on the recovery field, achieving a fixed-point vertical soft landing.


This test is currently the largest-scale vertical take-off and landing flight test of a reusable carrier rocket in China, and it is also the first application of the domestically developed deep variable thrust liquid oxygen-methane engine in a 10-kilometer-class return flight.
The entire test took about 6 minutes. The rocket went through five stages: accelerated ascent, decelerated ascent, accelerated descent, decelerated descent, and slow descent, achieving “take-off, accurate control, unfolding, and stable landing”.
