In a chemical rocket, hot gases are created by chemical combustion; in a nuclear rocket heating of the propellant in a nuclear reactor creates hot gas.

In either case, the hot gases flow through the throat of the rocket nozzle where they expand and Nuclear propulsion [and] chemical propulsion.

At the center of NASA’s nuclear rocket program is Bill Emrich, the man who literally wrote the book on nuclear propulsion.

“You can do chemical propulsion to Mars, but it’s really hard. Get this from a library. Nuclear propulsion [and] chemical propulsion: hearings before the Subcommittee on Science and Astronautics, U.S.

House of Representatives, Eighty-eighth Congress, second session. March 18 [United States. Congress. House. Committee on Science and Astronautics. Subcommittee on NASA Oversight.]. InNASA began an R&D effort to develop nuclear power and propulsion systems for solar system exploration.

This activity, renamed Project Prometheus inwas initiated because of the inherent limitations in photovoltaic and chemical propulsion systems in reaching many solar system objectives. Nuclear Propulsion for Rockets.

and CL/HJ chemical propulsion systems for an orbit-to-orbit vehicle operating in the earth-moon space. The orbit-to-orbit vehicle is assumed to use propellants delivered by a reusable earth-to-orbit shuttle (EOS).

Chemical retropropulsion is used, if necessary, to decrease entry speed to this value.

Starting in the mids, the United States initiated a program to develop nuclear propulsion for spacecraft. The basic technology involved passing hydrogen through a very high temperature nuclear reactor, where it expanded and blasted out of the reactor at high velocity.

NASA is currently investigating nuclear thermal propulsion as an alternative to chemical propulsion for manned missions to the outer planets. There are a number of materials being considered for use as fuel elements. These materials include tricarbides and CERMETS such as W/UO2, Mo/UO2, W/UN and Mo/UN.

All of these materials require high temperature processing to achieve the required : Dennis S. Tucker. The Naval Nuclear Propulsion Program comprises the military and civilian personnel who design, build, operate, maintain, and manage the nuclear-powered ships and the many facilities that support the U.S.

W., and R. DeLauer. Nuclear Rocket Propulsion, McGraw-Hill. Abstract—The nuclear thermal rocket (NTR) represents the next “evolutionary step” in high performance rocket propulsion.

Unlike conventional chemical rockets that produce their energy through combustion, the NTR derives its energy from fission of Uranium atoms contained within fuel elements that comprise the engine’s reactor by: Nuclear propulsion has emerged from the doldrums and is now seen as a definite possibility for outer solar system robotic exploration; and as enabling technology for a human mars expedition.

A new chapter on nuclear thermal propulsion has been added to reflect this revival of interest. Nuclear thermal propulsion (NTP) systems have been studied in both the USA and the former Soviet Union since the s for use in space science and exploration missions.

NTP uses nuclear fission to heat hydrogen to very high temperatures in a short amount of time so that the hydrogen can provide thrust as it accelerates through an engine : Douglas Burns, Stephen Johnson.Principles of Nuclear Rocket Propulsion provides an understanding of the physical principles underlying the design and operation of nuclear fission-based rocket engines.

While there are numerous texts available describing rocket engine theory and nuclear reactor theory, this is the first book available describing the integration of the two subject areas.chemical systems. As missions aim for targets farther out into the solar system, nuclear propulsion may offer the only viable technological option for extending the reach of exploration missions beyond Mars.
