China's first independently-developed 3.2-meter three-segment solid rocket motor for civil space completed its first ground test in Xi'an, Northwest China's Shaanxi Province on Wednesday, marking China's largest and the most powerful segment-type solid rocket engine tested to date.

Against the backdrop of China's rapid development in space technology, the new solid rocket booster can be applied to large and heavy rockets to meet varied development needs of space equipment, manned moon landing and deep space exploration, CCTV news reported on Wednesday.

Data revealed that the segmental solid rocket buster is a solid fuel rocket engine divided into several sections and each section has its own shell, adiabatic structure and propellant charge column.

This marked another major milestone in rocket development following the successful ground thermal testing of the 3-meter 2-segment large solid rocket booster developed by China Aerospace Science and Technology Corporation in August of 2016.
