Tethered combination body dragging and removing method based on on-off control of thruster

The invention discloses a tethered combination body dragging and removing method based on on-off control of a thruster, which comprises the steps that 1, an aircraft captures a target and forms a stable tethered combination body, the tethered combination body is adjusted to be of a horizontal configuration, the aircraft hovers relative to the target, and the tether is kept to be tensioned; 2, a thruster along the tether direction of the aircraft operates, and a tether winding and unwinding device releases the tether; 3, when the release speed of the tether is greater than a set speed, the thruster is turned off, the aircraft accelerates to get close to the target, and the tether winding and unwinding device withdraws the tether; 4, when the withdrawing speed of the tether is greater than aset speed, the thruster is turned on, the aircraft accelerates to get away from the target, and the tether winding and unwinding device releases the tether; 5, the step 3 and the step 4 are repeateduntil the tethered combina
