PROPULSION SYSTEM AND ROCKET HAVING THE SAME

摘要

The present invention provides a propulsion unit including a combustion pipe including a propellant inside; a nozzle jetting combustion gas generated in the ignition of the propellant by being installed on the rear end of the combustion pipe; and a nozzle separation unit which mounts the nozzle on the combustion pipe by being individually connected to the combustion pipe and the nozzle and separates the nozzle from the combustion pipe as at least a part is melted when reaching a pre-set temperature.
