Title:
TESTING DEVICE AND METHOD FOR TESTING STRENGTH OF AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2015/140863
Kind Code:
A1
Abstract:
Provided is a testing device for testing the strength of an aircraft using a curved specimen, the testing device being capable of safely and quickly generating desired stress by reliably applying inner pressure to the specimen, the testing device enabling the reliable observation of generated damage.
A testing device (1) for applying inner pressure, which corresponds to the difference in pressure between the outside and inside of a portion to be tested, to a curved specimen (10) corresponding to a portion to be tested of the fuselage of an aircraft is provided with: a pressure container (22) for forming a cavity (23) between the pressure container (22) and the specimen (10); and a rod (25) for restraining the specimen (10) against the inner pressure. The pressure container (22) faces the outer surface of the specimen (10). Inner pressure is applied to the specimen (10) by reducing pressure within the cavity (23).
