The main objective of this chapter will be to establish the foundations that allow us to obtain equations, that preliminarily give results for the hydrodynamic calculations and in-scale drawings of the HFP of the PHIT, and to determine a first approximation of the thickness of each component composing the physical parts. Once the critical sections have been established, we will need to specify the materials that will be used to manufacture the corresponding parts, within the allowable stress levels. Subsequently, the Manufacturing Project for the PHIT model can be developed by PT, taking into account the limitations of the laboratories where it will be tested. The resulting report will list the elements for carrying out the Executive and Manufacturing Project so that the PHIT can ultimately be built. Furthermore, a form will be identified, analyzed, and presented for the established geometries, that will allow us to calculate the main forces necessary to keep both the SCC and the QCC open and closed.
