The invention discloses a rocket takeoff mode, and belongs to the field of aerospace equipment. The rocket takeoff mode refers to a fixed wing aircraft, a control terminal and a rocket; two electromagnetic chucks and a signal module are mounted on the fixed wing aircraft; the two electromagnetic chucks are mounted on a back of the fixed wing aircraft; the sizes and the arrangement distance of thetwo electromagnetic chucks are designed according to the size and the length of a rocket body; the electromagnetic chucks adopt electromagnetic principles; the magnetic force of the electromagnetic chucks is controlled through a power supply for butt joint with absorption surfaces on the rocket; two absorption surfaces and a signal machine are mounted on the rocket; the absorption surfaces are made of materials easy to attract by the electromagnetic chucks; the absorption surfaces are positioned on the surface of the rocket body; the design distance of the two absorption surfaces correspondsto that of the two electromagnetic chucks; and the control terminal wirelessly controls the fixed wing aircraft and the rocket through the signal module and the signal machine. The rocket takeoff modechanges a traditional rocket takeoff mode; and the fixed wing aircraft can be recycled to reduce the rocket launching cost.
