The motion mechanism of a parallel TBCC combined nozzle is one of the key technologies for the success of TBCC technol-ogy verification.Various configurations of TBCC engines and corresponding nozzle schemes are introduced.The conceptual schemes of motion mechanisms with different engine configurations are elaborated through the detailed analysis of the research efforts of TBCC combined nozzle motion mechanisms abroad.Technical characteristics of two configurations of parallel TBCC nozzle motion mechanism are described.Future research directions of motion mechanism configuration of high Mach TBCC combined nozzle are discussed,including the development of multidisciplinary collaborative design optimization methods in terms of static strength,structural lightweight,stiffness,and heat-resistant,etc.,fluid-thermal-structural coupling motion simulation analysis methods,heated loading test techniques,and application technologies of new high-temperature resistant and high-strength material.
