The master's thesis presents a method for shock wave strengthening in a diaphragmless shock tube, which was developed for the dynamic calibration of pressure sensors. By considering the dynamic theory of shock waves based on Chester-Chisnell-Whitham relation, two designs for upgrading the shock tube to amplify shock waves were constructed. The process of designing the transformation curve under selected initial conditions is presented. The first design consists of a contraction and extension with a tube of narrower inner cross-section, while the second design consists of a contraction and a conical contraction to a minimal diameter. Both designs were manufactured and integrated into the existing system, and experimentally evaluated.
