Nuclear Rocket Propulsion latter may be further subdivided into liquid-, gas-, and plasma-core engines. Although fluid-core systems have been studied by a number of investigators during the past ten years, no major development activity has been initiated. Details of these systems are discussed in Chapter 9.
