Figure 2: Breakdown of Different Types of Rocket Propulsion Description of the Nuclear Fission Process Figure 3: Typical Fission Process of a Fissile Uranium-235 Atom. To generate the heat and thrust for a thermal propulsion system like NTP, a source of energy is needed. A nuclear thermal rocket (NTR) is a type of thermal rocket where the heat from a nuclear reaction, often nuclear fission, replaces the chemical energy of the propellants in a chemical rocket. In an NTR, a working fluid, usually liquid hydrogen, is heated to a high temperature in a nuclear reactor and then … Zobraziť viac Nuclear-powered thermal rockets are more effective than chemical thermal rockets, primarily because they can use low-molecular-mass propellants such as hydrogen. As thermal … Zobraziť viac A nuclear thermal rocket can be categorized by the type of reactor, ranging from a relatively simple solid reactor up to the much more difficult to construct but theoretically more efficient gas core reactor.
