Non Destructive Testing

NON-DESTRUCTIVE TESTING INTRODUCTION In aircraft maintenance programme it is primal to inspect the robotic damage and assess the extent of the repair work. only when in schedule maintenance it is a difficult to finding the defects rapidly, as the maintenance of aircraft must be accomplished in spite of appearance schedule condemnation and same to be released in time for commercialized operation. During aircraft maintenance NONDESTRUCTWE TESTING (NDT) is the most economical way of playacting limited review and this is the only way of discovering defects. In just now we bear say, NDT squeeze out detect cracks or whatsoever other irregularities in the airframe social structure and engine components which ar obviously not visible to the defenseless eye. Structures & different assemblies of aircraft argon made from various materials, such as aluminium alloy, steel, atomic number 22 and composite materials. To dismantle the aircraft i n pieces and indeed examine individually component would take a immense time, so the NDT system and equipment selection must be steady and effective. In the founder trend of NDT application on aircraft 70-80% of NDT is performed on the airframe, structure, landing gears and the lie carried out on engine & tie in components.

In order to maintain the aircraft defects free and ensure a lavishly degree of quality & reliability and as a composition 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. quiet Penetrant : Liquid penetrant scrutiny is one of the oldest of modern non-destructive testing methods & wide used in aircraft maintenance. Liquid penetrant testing can be defined as a physical & chemical non-destructive physical process designed to detect & expose surface connected discontinuities in nonporous engineering materials.
