He graduated from Northwest University in 1962 and received his doctor’s degree from the University of Cambridge in 1984. He has successively worked as President of the Chinese Aeronautical Establishment, Chief Engineer of the Ministry of Aerospace Industry (now known as China National Space Administration, China Aerospace Science and Technology Corporation and China Aerospace Science and Industry Corporation), Deputy Director General of the Aviation Industry Corporation of China (AVIC) and Director General of AVIC Ⅱ (now known as AVIC).
Prof. Zhang is an expert in aeronautic system engineering and signal processing. In 1960s and 1970s, he studied mechanical vibration and aircraft fault diagnosis, successfully removing faults of 55 planes. In 1980s, his research on information system solved the problem of limit cycle oscillation, and he systematically developed the subject of exclusive OR circuit simplification. In 1990s, he led the project establishment and system development of several planes, missiles and radars, and brought up the idea of cost systems engineering.
He has received two state-level and nine ministry-level awards. His publications include nine monographs, an English-Chinese dictionary and over 100 papers.
