The invention belongs to the technical field of helicopter material application and management, and particularly relates to a method for evaluating the sand corrosion resistance of a helicopter rotorblade protection material. The method specifically comprises the following steps of S1, manufacturing a rotor blade protection material test piece (100), S2, designing a test device (200), and installing the test piece (100), S3, determining a test parameter matrix, wherein the test parameters comprise a sand blowing angle, a sand blowing speed, a sand type and a test temperature, S4, performing atest according to the test parameter matrix determined in the step S3, and S5, evaluating test results. The method can be used for evaluating the sand corrosion resistance of the helicopter rotor blade protection material in the flight state, the effect which cannot be achieved by an existing traditional method at present is achieved, the evaluation result can provide important support for prediction of the actual service life of the blade protection material, and the domestic blank is filled up.
