 | An article by Marcel Gruen, published in the no. 3, May 1965 issue of the Prague Ceskoslovensky Casopis pro Fysiku (pp 207-244), reviews the various physical propulsion systems for rockets which have been tested in various nations in addition to the conventional chemical rocket engines. The author states that great attention has been devoted to electric motors, the development of which has entered the stage of practical application; rocket engines ... |

| Icebreakers impose limitations on a propulsion system that have been solved historically by the use of a D.C. motor directly coupled to the shaft driving the propeller. With the advent of high power silicon rectifier devices, several members of the Westinghouse Electric Corporation published papers which suggest the use of these rectifiers in an alternating current (A.C.) to direct current (D.C.) electric propulsion system for icebreakers. It was suggested that ... |

|
| Some basic aspects of ion beam neutralization in the presence of magnetic fields are investigated. The problem leads to an integro-differential equation for the electrostatic potential. This equation is solved numerically for several values of the electron-ion mass ratio. Of more interest for practical applications is the limit as the mass ratio tends to zero. In this case, the governing equation becomes linear and the problem reduces to finding the ... |

|
| This report describes the results of tests of a 1/28 scale model of a Novel Electric Power Propulsion System (NEPPS) and prediction of pro totype performance. Analysis of the test re sults leads to the following conclusions: (1) comparison of model cavitation data indicates that the cavitation performance of the NEPPS propeller is better than that of the conventional propeller; (2) torque measurements over a wide range of operating conditions ... |

| COMMENTARIES ON OPTIMIZATION OF F CONSTANT THRUST ELECTRICAL PROPULSION SYSTEMS, |

Haywood Shelton; THOMPSON RAMO WOOLDRIDGE INC LOS ANGELES CALIF
|
| D. B. Langmuir has calculated the exhaust velocities that optimize the mass ratio, the time, and the velocity increment for various weight to power ratios of the power source. E. Stuhlinger has used a different optimization involving the initial acceleration. This note will attempt to clarify the relative merits of these two optimization schemes and two others that naturally evolve from the analysis. |
