Pressure vessel and spacecraft having the same

摘要

A pressure resistant container which is less liable to be damaged due to stress concentration at a connection portion between a first outer shell member and a second outer shell member even in a deep sea at a water depth of 1000 m or more, and a probe equipped therewith are provided. A cylindrical first outer shell member (2) and a hemispherical second outer shell member (3) connected to both ends (2a, 2b) of the first outer shell member (2) A material having a Young's modulus E 2 of the base material constituting the shell member (3) smaller than the Young's modulus E 1 of the base material constituting the first outer shell member (2) is selected to construct a pressure resistant container (1).
