Liang Sili (simplified Chinese: 梁思礼; traditional Chinese: 梁思禮; 24 August 1924 – 14 April 2016) was a Chinese rocket scientist and academician. He was elected an academician of the International Academy of Astronautics in 1987 and the Chinese Academy of Sciences in 1993. He became the vice-president of the International Astronautical Federation in 1994.

Liang was the youngest son of Chinese scholar and reformist Liang Qichao.[1] His elder brothers, Liang Sicheng and Liang Siyong, were also academicians.[2]


Liang graduated from Purdue University in 1945, majoring in Electrical Engineering. He earned his doctor's degree in automation control from the University of Cincinnati in 1949.[3] He returned to China in late 1949 when the Chinese Communist Party took control of mainland China. He was appointed jobs at the Institute of Telecommunications Technology (Ministry of Posts & Telecommunications) and later the Institute of Electronic Science (Communication Department of PLA). In 1956, Liang transferred to the Fifth Institute of Ministry of Defense. He became the deputy director of the Research Office of Missile Control Systems, working under Qian Xuesen.[4] Liang played an important role in the design of the Dongfeng 2A missile, the Dongfeng 5 missile, the Long March 2 rocket, and the Long March 3 rocket.[4]

Liang died on 14 April 2016, at the age of 91, in Beijing.[5]
