Hall thrusters trap electrons in a magnetic field and use them to ionize the onboard propellant. It uses 10 times less propellant than equivalent chemical rockets. These new engines should have a profound impact on the future of spaceflight, NASA officials said. SEP engines are much more efficient than traditional chemical rockets, requiring less fuel to travel a given distance.
Space Propulsion and Plasmas Space Propulsion Most spacecraft being launched today host both conventional i. At Penn State, we are conducting research in a number of areas relevant to space propulsion. In the area of chemical propulsion, our experimental research includes characterizing the unsteady combustion behavior of solid and liquid propellant rockets by means of advanced diagnostics.
These measurements provide important input into the prediction of rocket-chamber combustion stability.
In advanced space propulsion, we conduct experimental, computational, and analytical research into microwave-heated propulsion, whereby propellant gases are heated to plasma temperatures to obtain performance higher than chemical rockets.
Thrusters are characterized under vacuum conditions via direct and indirect thrust measurements and various optical diagnostics.
Advanced propulsion for micro- nano- and CubeSats is being pursued with various miniature thrusters being designed and tested. Molecular dynamics MD and quantum lattice gas QLG simulations are developed of phenomena of interest to space propulsion such as two-phase and plasma flows.
Plasmas Plasmas are of interest because of their relevance to many advanced space propulsion systems. Other types of plasmas being investigated are low-temperature nonequilibrium, surface-wave, combustion-enhancing, and RF-generated plasmas.
We also conduct research in spacecraft—plasma interactions and electrodynamic tethers for energy propulsion, harvesting, and momentum exchange. Experimental Facilities Experimental facilities include two 1-meter-diameter vacuum chambers with associated pumping and thrust-measurement equipment.
Microwave sources from 2.
Optical and plasma probe diagnostics are used for plasma characterization. Our experimental facilities also allow for full-scale testing of small spacecraft in a low Earth orbit LEO —type environment.
Quality assurance tests can be formed at full-scale on 3-U CubeSats and potentially larger to assess system or component performance in a realistic plasma environment.Nuclear pulse propulsion or external pulsed plasma propulsion, is a hypothetical method of spacecraft propulsion that uses nuclear explosions for thrust.
It was first developed as Project Orion by DARPA, after a suggestion by Stanislaw Ulam in .
The Nuclear Engine for Rocket Vehicle Application (NERVA) was deemed ready for integration into a spacecraft, before the Nixon administration shelved the idea of sending people to Mars and.
The agency plans to use the advanced ion engines on a variety of missions, including its project to pluck a boulder off a near-Earth asteroid and drag the piece into orbit around the moon.
There, astronauts will visit the rock. A reusable launch system (RLS, or reusable launch vehicle, high-altitude (80 km) maglev systems such as launch loops, and more exotic systems such as tether propulsion systems to catch the vehicle at high altitude, or even Space Elevators.
Based on the research from Project Copper Canyon. The Vortex-Cooled Chamber Wall Engine: A Tamed Tornado - Designers hope a new rocket engine technology, combined with new vehicle designs and operating models, will dramatically reduce the cost of getting bulk goods to space - SPACE TIMES/California Space Authority - March/April (pdf).
Jun 16, · The In-Space Propulsion Program work being performed at the Glenn Research Center develops primary propulsion technologies that can benefit near and mid-term science missions by reducing cost, mass and/or travel times.
