A nuclear thermal rocket (NTR) is a type of thermal rocket where the heat from a nuclear reaction 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 expands through a rocket nozzle to create thrust .
A pulsed nuclear thermal rocket is a type of nuclear thermal rocket (NTR) concept developed at the Polytechnic University of Catalonia, Spain, and presented at the 2016 AIAA/SAE/ASEE Propulsion Conference for thrust and specific impulse (I sp) amplification in a conventional nuclear thermal rocket. [1] The pulsed nuclear thermal rocket is a ...
RD-0410 (РД-0410, GRAU index: 11B91) was a Soviet nuclear thermal rocket engine developed by the Chemical Automatics Design Bureau [1] in Voronezh from 1965 through the 1980s using liquid hydrogen propellant. [2] The engine was ground-tested at the Semipalatinsk Test Site, [3] and its use was incorporated in the Kurchatov Mars 1994 crewed ...
Nuclear thermal rockets can provide great performance advantages compared to chemical propulsion systems. Nuclear power sources could also be used to provide the spacecraft with electrical power for operations and scientific instrumentation. [12] Examples: NERVA (Nuclear Energy for Rocket Vehicle Applications), a US nuclear thermal rocket program
NASA will partner with the U.S. military's research and development agency, DARPA, to develop a nuclear thermal propulsion engine and launch it to space "as soon as 2027," NASA administrator Bill ...
A laser thermal rocket is both a type of beam-powered propulsion and a thermal rocket. The thermal energy source is a laser, which heats a working fluid in a heat exchanger. The working fluid is then expanded through a nozzle to produce thrust. Depending on the laser power, a laser thermal rocket can have a thrust-to-weight ratio similar to ...
In May 1946, the U.S. Air Force launched the Nuclear Energy for Propulsion of Aircraft (NEPA) project to explore the potential of nuclear energy for powering aircraft. [13] [14] This initiative led to a collaborative effort of the Air Force and the U.S. Atomic Energy Commission (AEC) known as the Aircraft Nuclear Propulsion (ANP) program, aimed at developing nuclear propulsion systems for ...
NASA will test a nuclear-powered rocket for space travel. The technology could speed up a manned trip to Mars from the current seven-month minimum to 45 days.
