Abstract: A nozzle for a rocket having a separator is provided to improve thrust efficiency by gradually increasing a non-symmetric thrust since the separator is abraded according to the increment of a fly height. A nozzle(110) for a rocket having a separator includes a shrink unit(111), a nozzle throat(113), and a diffusion expansion unit(112). One end of the shrink unit is connected to a combustion chamber and a cross-section of the shrink unit decreases in a direction of extending from the combustion chamber. The nozzle throat is connected to the other end of the shrink unit. The separator is mounted on an inner surface of the diffusion expansion unit. The separator generates a symmetric separation movement to control the balance between the pressure of an output terminal of the diffusion expansion unit and an external atmosphere of the diffusion expansion unit according to an altitude. The separator is made of an ablative material abraded according to the increment of a fly height.
