Non Destructive Testing

NON-DESTRUCTIVE TESTING INTRODUCTION In aircraft maintenance programme it is substantial to inspect the robotic damage and assess the extent of the repair work. scarce in schedule maintenance it is a difficult to conclusion the defects rapidly, as the maintenance of aircraft must be accomplished indoors schedule period 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 precisely we bear say, NDT squeeze out detect cracks or any(prenominal) other irregularities in the airframe social structure and engine components which be obviously not visible to the defenseless eye. Structures & different assemblies of aircraft ar made from various materials, such as aluminium alloy, steel, te and composite materials. To dismantle the aircraft in pieces and indeed examine apiece component would take a immense time, so the NDT manner and equipment selection must be steady and effective. In the feed trend of NDT application on aircraft 70-80% of NDT is performed on the airframe, structure, landing gears and the abide carried out on engine & tie in components.

In order to maintain the aircraft defects free and ensure a gritty degree of quality & reliability and as a give out of inspection programme, usually following NDT methods are apply; 1) transparent 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. crystalline 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 agency designed to detect & expose surface connected discontinuities in nonporous engineering materials.
