The invention relates to a parameter selection test method of a torsional spring for an airplane. The parameter selection test method comprises the steps of 1, measuring initial parameters of at leasttwo different types of test pieces with same material; 2, performing torsional test on the two different types of test pieces under same compression quantity, and selecting the test piece with maximum torsional rigidity; 3, selecting a first test piece to perform torsional test under different compression quantities, and performing compression test on the first test piece at different torsional angles; 4, selecting compression quantity when the rigidity of the first test piece is approximate to stability, rotating the first test piece at a preset torsional angle, and repeating torsional testfor 1,000 times; 5, performing ultimate torque measurement on the first test piece to obtain maximum stress of the first test piece; and 6, selecting the final torsional spring with good torsional rigidity repeatability and maximum press value for parameter selection test according to the repeated torsional test.
