The invention discloses a multiple-pipe-combined helical aerated capturing arm, belongs to the technical field of aerospace and solves the problem of an existing space target capturing mechanism. The multiple-pipe-combined helical aerated capturing arm is helical. The helical radius of the multiple-pipe-combined helical aerated capturing arm decreases progressively from the rear end to the front end. The multiple-pipe-combined helical aerated capturing arm comprises a helical outer sleeve and a plurality of helical inner aerated support core pipes, the inner aerated support core pipes support the outer sleeve, the helical radius of each of the outer sleeve and the inner aerated support core pipes decreases progressively from the rear end to the front end, and the radius of a cross section of each of the outer sleeve and the inner aerated support core pipes decreases progressively from the rear end to the front end. Adjacent inner aerated support core pipes are adhered to one another at joints, and the outer sleeve is adhered to connected inner aerated support core pipes at joints. A coil spring is arranged on the outer side of the helical shape of the outer sleeve, the length of the coil spring after being uncoiled is identical to that of the outer sleeve, and the outer surface of the coil spring is adhered to the outer sleeve so as to enable the outer sleeve to be coiled outwards along with the coil spring before aeration. The multiple-pipe-combined helical aerated capturing arm is used for capturing large space targets.
