Available in PDF, EPUB and Kindle. Book excerpt: An in-depth study has been conducted to determine the feasibility of the colloid core nuclear reactor (CCNR) for rocket propulsion. Investigations of powder containment, reactor criticality, nuclear fuel vaporization, heat transfer, and wall erosion are discussed. Results are scaled and integrated to specify an optimized design reactor rocket engine. Rocket engine performance is evaluated with respect to velocity capability, type of fuel, and fuel loss rate. It is concluded that the CCNR rocket engine is technically feasible, that a thrust-to-weight ratio of 6:1 is obtainable at 20,000 lb thrust, and that the maximum specific impulse cannot exceed 1020 sec. Furthermore, results indicate that the CCNR shows significant performance advantages over chemical and other nuclear rocket engines for missions requiring payloads on the order of 10,000 lb, with large excess velocity capability. Recommendations are made as to the steps necessary to the further development of the colloid core nuclear reactor rocket. (Author).

Book excerpt: The next giant leap for mankind will be the human exploration of Mars. Almost certainly within the next thirty years, a human crew will brave the isolation, the radiation, and the lack of gravity to walk on and explore the Red planet. However, because the mission distances and duration will be hundreds of times greater than the lunar missions, a human crew will face much greater obstacles and a higher risk than those experienced during the Apollo program. A single solution to many of these obstacles is to dramatically decrease the mission duration by developing a high performance propulsion system. The gas core nuclear rocket (GCNR) has the potential to be such a system. The gas core concept relies on the use of fluid dynamic forces to create and maintain a vortex. The vortex is composed of a fissile material which will achieve criticality and produce high power levels. By radiatively coupling to the surrounding fluids, extremely high temperatures in the propellant and, thus, high specific impulses can be generated. The ship velocities enabled by such performance may allow a 9 month round trip, manned Mars mission to be considered. Alternatively, one might consider slightly longer missions in ships that are heavily shielded against the intense Galactic Cosmic Ray flux to further reduce the radiation dose to the crew. The current status of the research program at the Los Alamos National Laboratory into the gas core nuclear rocket feasibility will be discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the XXth International Astronautical Congress compiles selected papers presented at the 20th International Astronautical Congress held in Mar del Plata, Argentina in 1969. This book is divided into five main topics—spacecraft engineering, astrodynamics, astrionics, bioastronautics, and problems of education. In these topics, this compilation specifically discusses the equatorial vibrations of a long flexible boom on a spin-stabilized satellite of non-zero radius; heat transfer to linear bodies in two-dimensional hypersonic low density; and limits of accuracy of general perturbations for satellites moving under constant forces. The rapid optimization of multiple-burn rocket flights; data transmission for planetary studies; and comparison of theoretical and experimental attitude data for the DODGE spacecraft are also elaborated. This text also covers the Apollo life-support and protective systems; bioastronautical aspects of Apollo biomedical operations; and development and applications of hot water rockets. This publication is recommended for astrophysicists and scientists of other disciplines related to astronomy.
