The invention discloses a design method of a piston assembly for an aviation brake airplane wheel, and belongs to the field of airplane wheel brake systems. The method comprises the steps of determining the piston total area according to brake torque requirements; the piston stroke is determined according to the reserved abrasion thickness of the brake disc and the axial deformation amount of the brake device; designing a gap adjusting mechanism; the gap adjusting mechanism comprises a return spring, a spring seat, an expansion pipe and a pull rod; determining the piston diameter and the number of pistons according to the total area of the pistons; the brake clearance is determined according to the designed clearance adjusting clearance and the brake deformation amount; performing sealing ring type selection according to the sealing performance of the piston; the material surface treatment mode is determined according to the natural environment and the mechanical environment. According to the method, the design input requirement of the piston assembly and the specific steps of the design process are limited, the piston assembly for the brake airplane wheel meeting the requirement of an airplane can be designed, and the method has high application value.
