Method of determining moulded gasbag of tail rotor blade through CT detection

The invention belongs to the field of helicopter assistant detection and particularly relates to a method of determining a moulded gasbag of a tail rotor blade through CT detection. At present, on the premise of not destroying the tail rotor blade, methods of X-ray inspection, vision inspection and knocking inspection and the like cannot be used for determining the thickness of a skin and a leading edge, so that a method of nondestructive testing on the premise of not destroying the tail rotor blade is required. According to the method, through layering detection of leading edge of the tail rotor blade with CT, a CT cross section anatomy scanning image in all directions is obtained, thereby providing a simple and fine unique tool which can show all detains of an object and is used for observing layer-grade parts. During production, the method of CT to perform identification and inspection on the leading edge form of the tail rotor blade is a lossless inspection method which is effective of controlling product quality and increasing product safety.
