Non Destructive Testing

NON-DESTRUCTIVE TESTING INTRODUCTION In aircraft maintenance programme it is grievous to inspect the robotic damage and assess the extent of the repair work. only in schedule maintenance it is a difficult to conclusion the defects rapidly, as the maintenance of aircraft must be accomplished at bottom schedule meter and same to be released in time for commercialized operation. During aircraft maintenance NONDESTRUCTWE TESTING (NDT) is the most economical way of playing limited review and this is the only way of discovering defects. In plainly we bear say, NDT squeeze out detect cracks or whatever other irregularities in the airframe social structure and engine components which be obviously not visible to the defenseless eye. Structures & different assemblies of aircraft are made from various materials, such as aluminium alloy, steel, titanium and composite materials. To dismantle the aircraft in pieces and indeed examine all(p renominal) component would take a immense time, so the NDT order and equipment selection must be steady and effective. In the set up trend of NDT application on aircraft 70-80% of NDT is performed on the airframe, structure, landing gears and the informality carried out on engine & tie in components. In order to maintain the aircraft defects free and ensure a spirited degree of quality & reliability and as a ramify of inspection programme, usually following NDT methods are apply; 1) bland penetrant 2) Magnetic particle, 3) Eddy current 4) Ultrasonic 5) skiagraphy (x-ray/gama ray) 6) optic/Optical 7) Sonic/Resonance 8) Infrared Thermography. disparate NDT METHODS 1. limpid Penetrant : Liquid penetrant scrutiny is one of the oldest of modern non-destructive testing methods & astray used in aircraft maintenance. Liquid penetrant testing can be defined as a physical & chemical non-destructive mental process designe d to detect & expose surface connected disc! ontinuities in nonporous engineering materials.
