Creators

Description

Description is given of a method for determining whether a pneumatic tyre comprises separation areas between rubber and canvas or highly-porous zones. A gamma-ray-emitting radioactive gas is injected under pressure into the tyre, and at least one radiation detector is moved along the tyre surface. This can be applied to aeronautics

Abstract (French)

On decrit un procede pour determiner si un pneumatique presente ou non des zones de decollement entre gomme et toile ou des zones de porosites importantes. On injecte sous pression a l'interieur du pneu un gaz radioactif emetteur de rayons gamma et on deplace a la surface du pneu au moins un detecteur de rayonnement. Ceci est applicable en aeronautique
