Parametric Study of an Air-Breathing Electric Propulsion for Near-Space Vehicles
Journal of Propulsion and Power, 2018An air-breathing electric propulsion system is regarded as a potential alternative propulsion system to the propeller system for near-space vehicles.

Electric space propulsion systems
Space Science Reviews, 1967Active development of electric thrustors began 10 years ago. Today, several kinds of thrustors have achieved efficiencies above 90 % and lifetimes of several thousand hours. The following article derives the basic theory of electric thrust production at constant exhaust velocity, and at variable exhaust velocity programmed for optimum vehicle ...

Electronics and Power, 1968
In the past 20 years, electrical methods of propelling space vehicles have developed from the speculative stage to practical reality. While it is inconceivable that electric thrustors could be used as rocket launchers, once in orbit electric propulsion is particularly suited to missions where a source of electric power is also required for some other ...

Space station propulsion options
21st Joint Propulsion Conference, 1985The selection of the propulsion system for the Space Station represents a complex issue. The present paper provides a summary of the Station design factors which dictate the propulsion requirements, taking into account approaches for meeting these requirements.

Since the dawn of the Space Age, hundreds of humans have entered this strange new realm in modern-day equivalents of the Yankee Clipper. Twenty-four (three of them twice) have orbited our Moon or landed upon it and viewed the Earth as a precious blue-green orb suspended in the inky blackness of the void.

Advanced space propulsion concepts
Acta Astronautica, 1987Abstract Demands are being made for higher performance, more durable, more flexible and lower cost propulsion systems to satisfy spacecraft launch and orbit transfer requirements. The Air Force Rocket Propulsion Laboratory is developing space propulsion having various attributes to meet the transport challenges imposed by modern spacecraft ...

IRE Transactions on Military Electronics, 1959
The possible role of a controlled thermonuclear reactor in space missions is discussed. Although such a reactor is many years from reality, some of its properties are understood well enough to indicate problems which will appear and which are peculiar to space flight. It appears that it will have to deliver electric power or thrust at a weight of about

Gravity Propulsion Space Travel
Journal of Physics & Optics Sciences, 2022For thousands of years science assumed that the natural force known as gravity was an attraction force. In a previous article it was shown that gravity is a repulsion force rather than an attraction one. This new outlook on gravity explained why the Relativity theory claiming relativistic length contraction and time dilation is undecidable.

Plasma Physics and Controlled Fusion, 2011
Plasma thrusters are challenging the monopoly of chemical thrusters in space propulsion. The specific energy that can be deposited into a plasma beam is orders of magnitude larger than the specific chemical energy of known fuels. Plasma thrusters constitute a vast family of devices ranging from already commercial thrusters to incipient laboratory ...
