Description

Technical Field

[0001] This application relates to the field of aircraft maintenance technology, and more specifically, to a training platform for repairing aircraft wing skin. Background Technology

[0002] The wing is a crucial component of an aircraft, its primary function being to provide lift and, together with the tail, ensure good stability. Skin-framed wings are a common wing construction. The skin is typically made of metal or composite materials and is usually riveted to the frame. Its direct function is to create a streamlined wing surface; to minimize drag, the skin should be as smooth as possible. When learning aircraft wing skin repair techniques, students often lack frequent contact with aircraft, and without adequate teaching and training equipment, it is difficult to achieve good operational results.
