11. THE JOURNAL OF SPACE FLIGHT 649. "Rocket Power -- Its Place in Aeronautics." Aviation Week. January 9, 1950. A brief analysis is given of high-thrust rockets showing beneficial characteristics, design parameters and application details. HS 650. "Characteristics of Disk-Controlled Flame." AeroDigest July 1950. A report based on the findings of the thermodynamics section of the Westinghouse Research Laboratories, on the effect of velocity, size, pressure and fuel-air ration on the flame-holding ability of a bluff body. HS 651. "The Trajectory of a Powered Rocket in Space." J. B. Interplanetary Society by George F. Forbes. A mathematical analysis of a rocket in general conditions of tangential thrust is treated as a particle being acted upon by an unspecified force with its mass is varying at an unspecified rate. The special case of the logarithmic spiral is shown to simplify the mathematics of navigation. HS 652. "The Significance of Monatomic Gases in Planetary Space Operations." Part I. Wayne Proell. J. Space Flight, Sept. 1950. The author explores the consequences of the existence of high concentrations of atomic oxygen and nitrogen above the 100Km level, as regards space flight. Such gases are indicated to have important effects of ramjet-accelerated space ships, space stations and guided missiles at extreme ranges or in satellite orbits. Mathematical analysis shows that the atomic oxygen layer cannot greatly increase the fuel efficiency of ram jets. However at near satellite velocities, ramjets in this layer will operate without fuel due to recombination of dissociated oxygen in the pressure zone of the ramjet, giving a fuel less ramjet. A brief calculation indicates that the amount of thrust obtainable from this source is small, an exhaust velocity being obtained of 5 meters/second without fuel. The atomic oxygen layer is suggested as being a great reservoir of available solar energy, and some methods of harvesting this energy are discussed. WAP 653. ibid part II, October 1950. The operation of guided missiles, satellite stations, and spacecraft in the 100-300 Km altitude levels is discussed with relation to recombination of atomic gas on the surface of such vessels. It is shown that the energy liberated while significant, is small in comparison with solar heating. The application of kinetic theory of gases to the problems of gas adsorption at these levels is discussed. The fuelless ramjet appears operable in the velocity range of 1 to 8 Km/sec. at altitutdes of 100 to 145 Km giving an exhaust velocity of 2450 M/sec. Such a ramjet may be a practical means of using the stored solar energy at these altitudes. Applications to space flight and to other planets are suggested. NJB
