Nuclear Thermal Propulsion
A propulsion technology that uses a nuclear reactor as a heat source to directly heat a propellant, usually liquid hydrogen. Its specific impulse can reach about 900 seconds, and it provides relatively high thrust, making it suitable for rapid orbital changes and shortened interplanetary flight times.
Timeline (last 90 days)
The common precondition for nuclear thermal propulsion and nuclear electric propulsion is the miniaturization and safe encapsulation of space nuclear reactors.
Nuclear thermal propulsion uses a reactor to heat propellant (usually liquid hydrogen) and expel it directly to generate thrust, with specific impulse reaching more than twice that of chemical rockets.
Nuclear thermal propulsion (NTP) can raise specific impulse to around 900 seconds.
NTP heats low-molecular-weight propellants such as liquid hydrogen by flowing them through the core of a nuclear fission reactor to above 2500 K before expelling them, achieving a specific impulse of approximately 900 seconds, roughly double that of conventional liquid oxygen/liquid hydrogen engines (approximately 450 seconds).
Nuclear Thermal Propulsion (NTP) uses a nuclear reactor to heat propellant to generate thrust, with a specific impulse approximately twice that of chemical rockets, reaching about 900 seconds, compared to approximately 450 seconds for conventional liquid oxygen/liquid hydrogen engines.
The specific impulse of nuclear thermal propulsion can reach approximately 900 seconds, roughly twice that of conventional liquid oxygen/liquid hydrogen engines (approximately 450 seconds).
