Detection of corrosion damage in aircraft wing skin structures is an ongoing NDT challenge. Ultrasonic methods are known and well-accepted techniques, which are relatively simple to carry out in terms of setup, probes and instrumentation and operator training. However, with conventional inspection from the top surface using a transducer at normal incidence (0o to the normal to the surface) producing a visual picture in the form of a C-scan, it is very tie consuming to point-by-point inspects large aircraft wing skin areas. In addition it is too ....etc

Corrosion of reinforcements has been one of the major challenges that the civil engineers have been facing. Corrosion leads to the formation of rust which results in the spalling of concrete which in turn leads to the exposure of rebars to the aggressive environment. This will accelerate the ill effects and ultimately leads to the break down of the structure. Corrosion mainly occurs in areas of aggressive environment such as coastal regions. It is very important that corrosion of reinforcement must be prevented in order to have a durable struct ....etc

1.AN INTRODUCTION TO AIRCRAFTS
1.1 Components of Aircraft:
Aircrafts come in many different shapes and sizes depending on the mission of the aircraft, but all modern airplanes have certain components in common. These are the fuselage, wing, tail assembly and control surfaces, landing gear, and power plant(s).
• The fuselage:
It is the body of the airplane that holds all the pieces of the aircraft together and many of the other large components are attached to it. The fuselage is generally streamlined as much as ....etc

Deterioration of reinforced concrete structures due to corrosion of steel is a cause of global concern. The losses due to corrosion every year run into millions of rupees and any solution to this universal problem of corrosion has a direct bearing economy of the country. It is estimated that about 30-40 percent of steel produced each year is used to replace corroded material.
In recent years, the construction industry has seen an increased demand to reinstate, rejuvenate, strengthen and upgrade existing concrete structures. This may be attrib ....etc
