Laser Launch Systems The Lawrence Livermore National Laboratory's Special Studies Program (within The Advanced Technology Program (ATP) of O Division) has examined alternative spacecraft propulsion concepts to meet performance or mission objectives. Laser propulsion concepts have been described for several decades. The laser beam is used to heat a propellant with the energetic expansion driving the craft. A series of ATP devised tests were conducted in which a laser beam was directed at a pusher plate with machined paraboloid dimples. Light was focused by each dimple on a spot behind the plate. The focused beam heated air pockets and the expanding pockets imparted a thrust to the plate. This *concept* provides respectable thrust in the atmosphere. In *space* (vacuum) the dimpled plate is jettisoned to expose a block of solid propellant which is ablated by the laser beam to produce thrust.

Topics of interest include experiments and theories regarding the coupling of gravity and electromagnetism, the quantum vacuum, hyper fast travel, and super luminal quantum effects. Because the propulsion goals are presumably far from fruition, a special emphasis is to identify affordable, near-term, and credible research that could make measurable progress toward these propulsion goals.

Experimental Rocket Propulsion Society The Bay Area's Non-profit Liquid Fuel Rocket Engine Design and Test Team HOME Intro FAQ Mailing list ... Stats Search ERPS: The E.R.P.S. was founded in February of 1993 to gather together interested amateurs to learn about, design, build, and test liquid fuel rocket engines. The group early on decided to concentrate on developing and testing high density storable propellant combinations because they allowed the maximum amount of work to be done with the minimum amount of risk to life and limb. After research and consultations, high density Hydrogen Peroxide (H O ) was selected as the oxidizer of choice, with the intent to combine it with a high-density kerosene such as JP5 or regular Jet-A. Peroxide, when catalyzed, produces steam (2 H O) and pure oxygen (O ) at high temperatures. Peroxide makes a fair mono-propellant when used in concentrations above 95% and there was historical experience (the British 'Black Knight' program of the late 60's and early 70's) to show that respectable performances and capabilities could be developed even at lower concentration when combined with a high density liquid hydrocarbon. The British, however, limited themselves by the catalyst they chose to work with, silver screens. Because the melting point of silver is low (936.93 o C), using peroxide at concentrations above about 85% generates a heat of reaction high enough to melt the silver and thereby reduce and eventually eliminate the "catalyst" from the reaction. The physical properties of the reaction and the type of catalyst used, therefore, limited their performance.

Beginner's Guide to Propulsion Glenn Research Center Welcome to the Beginner's Guide to Propulsion What is propulsion? The word is derived from two Latin words: pro meaning before or forwards and pellere meaning to drive. Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction. A gas, or working fluid , is accelerated by the engine, and the reaction to this acceleration produces a force on the engine. A general derivation of the thrust equation shows that the amount of thrust generated depends on the mass flow through the engine and the exit velocity of the gas. Different propulsion systems generate thrust in slightly different ways. We will discuss four principal propulsion systems: the propeller,

SPDL Electric Propulsion Activities Overview Electric propulsion is most broadly defined as the acceleration of propellants by electrical heating, electric body forces, and/or magnetic body forces. This leads to a natural division of the three forms of electric propulsion. In Electro-Thermal thrusters, the propellant gas is electrically heated and expanded through a nozzle. Common examples include resistojets and arcjets. In Electro-Static thrusters, the propellant is ionized and the resulting ions are accelerated through an electric potential. Common examples include Hall effect and Kaufmann type thrusters. Electro-Magnetic thrusters utilize electric and magnetic body forces to accelerate ions. The most common type of electromagnetic thruster is the magnetoplasmadynamic thruster, or MPD. Research Statement Electric propulsion technology is steadily improving as our understanding of the physics governing thruster operation increases. Efforts that combine both experimental and theoretical studies of the plasmas within electric propulsion thrusters are necessary in order to build reliable models of performance that can be then used as design tools for improved next generation thrusters. Areas of Active Research Arcjet Thrusters Due to their relatively high specific impulse (500-1,200 sec.) and moderate thrust levels, electro-thermal arcjet thrusters are playing a growing role in satellite propulsion. Existing and planned applications include arcjet thrusters for station-keeping and on-orbit maneuvering. Low power hydrazine arcjets are now in use on the TelStar IV class of communication satellites and the first space test of a high power arcjet for use in orbit raising operations will be launched in 1997 under the Air Force

Aircraft Nuclear Propulsion - Introduction DIRECTORY HOME INTRODUCTION TECHNOLOGY POLITICS CONCLUSION BIBLIOGRAPHY ... EMAIL In addition to this paper, I found an article from the March, 1995 issue of Aviation History, Dream of Atomic Powered Fight, online. I've marked that up for your reading pleasure. Another interesting page is Anno Atomi: Growing Up with the Atom The Decay of the Atomic Powered Aircraft Program MegaZone Introduction Interest in atomic energy hit full force following World War II. The scientists who had raced to produce a bomb had also developed theories for a number of possible uses for the atom. Martin Mann lists a number of them in his book, Peacetime Uses of Atomic Energy. Ideas ranged from power generation, to nuclear excavation, to nuclear propulsion for vehicles on land, sea, and in the air. There were proposals for nuclear ships, nuclear locomotives, nuclear automobiles, and nuclear aircraft. It is this last proposal that is the topic for this paper, which will examine the technical and socio-political aspects of the United States Air Force's Aircraft Nuclear Propulsion (ANP) program and associated programs, including the reasons the ANP program was undertaken, and the reasons it was canceled after a decade of work.
