Preface
Pneumatic servo control originated from the gas servo system of missile and rocket
attitude control before and after World War II. In the past 60 years, in order to develop
space in Europe and America, cold air or hot gas has been used as working medium for
rocket attitude control and thrust vector control of aircraft. The attitude control of
China’s Long March series launch vehicles uses cylinder gas source to drive pneumatic turbine and hydraulic pump to generate hydraulic energy. The thrust vector
control of missiles and large launch vehicles uses integrated gas turbine pump
electro-hydraulic integrated energy device. Because high-temperature, high-pressure,
high-speed hot gas and ultra-high-pressure cold gas technology can be used in weapon
systems, at present, countries have implemented strict control and blockade on
aerospace high-speed pneumatic control theory and technology, and public reports are
extremely rare. In 1960, J. L. Shearer, an American, co-authored Fluid Power Control,
the first book on hydrodynamic control, based on pneumatic motor experiments. In
1963, the Japan Welding Association applied pneumatic system to automotive body
spot welding machine, pneumatic solenoid valve and pneumatic proportional valve
came out one after another. In 1965, Araki Kenji published Servo Mechanism, a
representative work on pneumatic servo mechanism, which used chamber and spring
compensation for pneumatic servo valves. In 1986, Chinese Qu Yiyi summed up the
essence of foreign literature and compiled Pneumatic Servo System. For many years,
high-temperature, high-pressure, high-speed, and high-precision pneumatic control
theory and technology have been listed as the key research topic in various countries,
but the public information and results are rare.
In view of the lack of basic theory of high-speed pneumatic control in aerodynamics, the author systematically and timely summarizes the advanced basic
theory and application technology of high-speed pneumatic control, especially the
basic theory and key technologies applied to major projects formed in the process of
research and development in aerospace, aviation, construction machinery, new
energy vehicles, automated production lines, and other equipment, based on many
years of practice in the development of major equipment and weapon systems
including the pneumatic series research topics undertaken by the author founded by
the National Defense Weapon System, the National High-tech Research and
