ULTRAFAST-LASER DRIVEN PLASMA FOR SPACE PROPULSION NIAC Final Report Submitted to Dr. Robert A. Cassanova NIAC Director A Fourteenth Street NW Atlanta, GA By Dr. Terry Kammash Principal Investigator Department of Nuclear Engineering and Radiological Sciences University of Michigan Ann Arbor, MI Tel: () Fax: ( File Size: KB. Advanced propulsion breakthroughs are near. Spacecraft have been stuck at slow chemical rocket speeds for years and weak ion drive for decades. However, speeds over .
Beamed Energy Propulsion, detailed in our book "The Lightcraft Flight Handbook: LTI," is inherently a clean technology. It uses electricity, which can be produced in an eco-friendly manner. Interstellar travel is crewed or uncrewed travel between stars or planetary tellar travel would be much more difficult than interplanetary s the distances between the planets in the Solar System are less than 30 astronomical units (AU), the distances between stars are typically hundreds of thousands of AU, and usually expressed in light-years.
Both laser- and solar-powered orbit-transfer vehicles (OTV's) make a tug concept viable, which substantially reduces cumulative initial mass to LEO in comparison to chemical propulsion concepts. Lunar cargo missions utilizing laser electric propulsion from Earth-orbit to LLO show substantial mass saving to LEO over chemical propulsion more.

The assumptions shown in table I (ref. 1) result in laser electric propulsion trip times shorter than solar electric propulsion trip times.
These shorter trip times are a result of the higher power level achievable with a laser-illuminated PV array. SPACE-BASED LASER SYSTEMS (SBLS's) A ground-based laser system can provide high power and reduce File Size: 7MB.
Laser propulsion can also continue to be used once the rocket is in space, to raise the vehicle to a higher orbit, or to boost it to a transfer orbit.
Another propulsion system is laser-electric propulsion, the use of a laser to illuminate a solar array to power an electric thruster. A new method of providing power to space vehicles consists of using ground-based lasers to beam power to photovoltaic receivers in space.
This can be used as a power source for electrically propelled orbital transfer vehicles. NASA Subject Category: SPACECRAFT PROPULSION AND POWER: Report No: 93N NASA-TM E NAS AIAA. An exposition of Kantrowitz's laser propulsion ideas were published in  Laser propulsion systems may transfer momentum to a spacecraft in two different ways.
The first way uses photon radiation pressure to drive momentum transfer and is the principle behind solar sails and laser sails. The second method uses the laser to help expel mass from the spacecraft as in a conventional rocket. The first systematic analysis of electric propulsion systems was made by Ernst Stuhlinger in his book Ion Propulsion for Space Flight, publishedinand the physics of electric propulsion thrusters was first described comprehensively in a book by Robert Jahn in Transportul energiei electrice fără fir (ss energy transfer) este transmiterea de energie electrică de la o sursă de energie la consumatorii de energie electrică fără conductori interconectați artificial (fără fire).Acest mod de transport al energiei este foarte util deoarece firele interconectate sunt scumpe, periculoase sau imposibile (în anumite locuri nu pot fi.
An electrically-powered spacecraft propulsion system uses electrical, and possibly also magnetic fields, to change the velocity of a of these kinds of spacecraft propulsion systems work by electrically expelling propellant (reaction mass) at high speed.
Electric thrusters typically use much less propellant than chemical rockets because they have a higher exhaust speed (operate. C. Phipps, Comparative Performance of Laser and Electric Space Propulsion, Final report, CNES document AVP-NTZZCNRS (), available from CNES Google Scholar C.

While we're able to propel particles to close to the speed of light in the lab, we're struggling to even accelerate spacecraft to beyond 3 percent of that.

Electric Propulsion (EP) is a class of space propulsion which makes use of electrical power to accelerate a propellant by different possible electrical and/or magnetic means.
The use of electrical power enhances the propulsive performances of the EP thrusters compared with conventional chemical thrusters. Unlike chemical systems, electric propulsion requires very little mass to accelerate a. Laser propulsion is a form of Beam-powered propulsion where the energy source is a remote (usually ground-based) laser system.
This form of propulsion differs from a conventional chemical rocket where both energy and reaction mass come from the solid or liquid propellants carried on board the vehicle. The concept of laser propelled vehicles was first introduced by Arthur Kantrowitz in Get this from a library!
