Development of the algorithm for the movement of the measuring module of the system of automated non-destructive testing of the nozzle of a lpre

The paper considers the development of the algorithm for the movement of the measuring module of the system of automated non-destructive testing of solder joints of the nozzle of a liquid propellant rocket engine (LPRE). The object of control, the flaws in soldered joints that arise during the manufacturing process, as well as the problems of production and testing of assembly units, are described. The main factors that reduce the probability of detecting defects are determined, and solutions are proposed. The necessity of using route construction algorithms in the developed traffic algorithm is substantiated. An algorithm for obtaining the path of the transducer movement for the measuring module of the system of automated non-destructive testing of solder joints is defined to detect such defects as "dry joint", "cold lap" and "partial dry joint".
