NON-DESTRUCTIVE TESTING INTRODUCTION In aircraft maintenance programme it is authorized to inspect the robotic damage and assess the extent of the repair work. provided in schedule maintenance it is a difficult to finding the defects rapidly, as the maintenance of aircraft must be accomplished at bottom schedule date and same to be released in time for commercialized operation. During aircraft maintenance NONDESTRUCTWE TESTING (NDT) is the most economical way of acting limited review and this is the only way of discovering defects. In only when we bear say, NDT squeeze out detect cracks or any(prenominal) other irregularities in the airframe social structure and engine components which argon obviously not visible to the defenseless eye. Structures & different assemblies of aircraft are made from various materials, such as aluminium alloy, steel, si and composite materials. To dismantle the aircraft in pieces and indeed examine distributively component would take a immense time, so the NDT regularity and equipment selection must be steady and effective. In the infix trend of NDT application on aircraft 70-80% of NDT is performed on the airframe, structure, landing gears and the pass off carried out on engine & tie in components.
In order to maintain the aircraft defects free and ensure a senior high school degree of quality & reliability and as a give way of inspection programme, usually following NDT methods are apply; 1) eloquent penetrant 2) Magnetic particle, 3) Eddy current 4) Ultrasonic 5) skiagraphy (x-ray/gama ray) 6) opthalmic/! Optical 7) Sonic/Resonance 8) Infrared Thermography. disparate NDT METHODS 1. gas Penetrant : Liquid penetrant scrutiny is one of the oldest of modern non-destructive testing methods & widely used in aircraft maintenance. Liquid penetrant testing can be defined as a physical & chemical non-destructive action designed to detect & expose surface connected discontinuities in nonporous engineering materials.
