Laser Holographic Vacuum Stressing Nondestructive Testing of Solid Fuel Propellant Grain

Abstract

This article introduces the status and results of the use of a type of large-scale internal optical path vacuum stressing laser holographic nondestructive testing instrument in checking for viscosity flaws along layer surfaces of fuel packs in the motors of solid fuel rockets. Moreover, it discusses the advantages and disadvantages of carrying out this type of check using methods incorporating thermal stressing and vacuum(low pressure) stressing.
