The invention belongs to the field of aircraft skin damage detection, and provides an aircraft skin damage nondestructive testing device which comprises a transmitting subsystem, a receiving subsystem, a signal processing subsystem, a control subsystem, a servo subsystem and a vehicle carrying subsystem. The transmitting subsystem is used for generating and transmitting signals; the receiving subsystem is used for receiving the echo signal and obtaining a digital echo signal through processing such as amplification, down-conversion, acquisition and storage for subsequent imaging detection processing; the signal processing subsystem is used for performing imaging processing on the received digital echo signal to obtain an aircraft skin echo imaging picture; and the echo imaging picture is analyzed and interpreted through skin damage detection software, and the damaged part of the aircraft skin is obtained. According to the scheme, aircraft skin damage detection can be carried out more accurately and economically.
