How does a Nuclear Thermal Propulsion system generate thrust for a spacecraft?
Answer
It uses a nuclear reactor to heat liquid hydrogen propellant to extreme temperatures for exhaust.
In a Nuclear Thermal Propulsion system, the nuclear reactor serves as the engine core. A propellant, typically liquid hydrogen, is passed through the reactor where it is heated to immense temperatures. This rapid heating causes the hydrogen to expand significantly and exit through a nozzle at high speeds, creating the necessary thrust for movement.
