Returned to China in 1949. Professor and adviser, Science and Technology Council of China Aerospace Corporation and member of the International Academy of Astronauts.

Liang participated in the establishment of the Chinese astronautical industry. He developed a strapdown guidance system with Chinese features for an IRBM, and contributed to the successful testing of Chinese nuclear missile weapons. In the early 1970s, he was the first to develop inertial platform on-board computer guidance system and to use an on-board computer to test the entire missile in long-range S-S missiles. In 1980 he participated in the successful missile launch toward the Pacific Ocean. He initiated astronautical engineering reliability by pointing out that ''reliability comes from design, manufacturing and management". As a result, the reliability of the Long March II launch rocket was improved greatly. He led the development of the CAMAC system, which standardized the ground test systems for missiles and satellites. He was an advocate of CAD/CAM in the astronautic industry.

He was elected Member of the Chinese Academy of Sciences in 1993.
