Abstract
To provide an aircraft strength testing apparatus that, using a curved specimen, can produce a desired stress safely and quickly by reliably applying an internal pressure, and moreover allows any resulting damage to be reliably observed. A testing apparatusthat applies an internal pressure, equivalent to a differential pressure between the outside and the inside of a section to be tested of a fuselage of an aircraft, to a curved specimencorresponding to the section to be tested, includes: a pressure vesselbetween which and the specimena cavityis formed; and rodsthat restrain the specimenagainst the internal pressure. The pressure vesselfaces the outer side of the specimen. By reducing the pressure inside the cavity, an internal pressure is applied to the specimen
