A novel variable-thrust nuclear thermal propulsion system comprises a hydrogen working medium main propellant supply system, an auxiliary propellant supply system, a propellant mixer, a reactor system, a regenerative cooling spray pipe, a corresponding control system and a corresponding pipeline valve. A thrust is controlled by changing the components of the propellant; a main propellant and an auxiliary propellant are mixed in the propellant mixer, then enter the pressure vessel, are heated by the reactor core, then enter the regeneration cooling spray pipe, expand and accelerate to be discharged out of the whole propelling system, and the thrust is generated. The thrust control mode is safer, and the adopted auxiliary propellants are various in variety, easy to prepare and high in cost performance. The novel variable-thrust nuclear thermal propulsion system is higher in economical efficiency and flexibility and suitable for serving as propulsion power of future deep space exploration spacecrafts.
