Advanced Electric Propulsion System (AEPS) is a solar electric propulsion system for spacecraft that is being designed, developed and tested by NASA and Aerojet Rocketdyne for large-scale science missions and cargo transportation. [1] The first application of the AEPS is to propel the Power and Propulsion Element (PPE) of the Lunar Gateway, [1 ...
Selected advanced electric propulsion projects developed propulsion technology systems in the 50 to 300 kilowatts (67 to 402 hp) range to meet the needs of a variety of deep space mission concepts. The three NextSTEP advanced propulsion projects, $400,000 to $3.5 million per year per award, were limited to a three-year performance period ...
Spacecraft electric propulsion. Spacecraft electric propulsion (or just electric propulsion) is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generating thrust to modify the velocity of a spacecraft in orbit. [1] The propulsion system is controlled by power ...
Variable Specific Impulse Magnetoplasma Rocket. The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is an electrothermal thruster under development for possible use in spacecraft propulsion. It uses radio waves to ionize and heat an inert propellant, forming a plasma, then a magnetic field to confine and accelerate the expanding plasma ...
A pulse detonation engine (PDE) is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. [1][2] The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave and the next. Theoretically, a PDE can operate from subsonic up to a hypersonic flight speed of ...
The Helical engine is a proposed spacecraft propulsion drive that, like other reactionless drives, would violate the laws of physics. [1] [2] [3]The concept was proposed by David M. Burns, formerly a NASA engineer at the Marshall Space Flight Center in Alabama, in a non-peer-reviewed report published on a NASA server in 2019 describing it as "A new concept for in-space propulsion is proposed ...
The Demonstration Rocket for Agile Cislunar Operations (DRACO) is an under-development spacecraft by Lockheed Martin in partnership with BWX Technologies as part of a DARPA program to be demonstrated in space in 2027. [2][3] The experimental vehicle is planned to be reusable and will utilize next-generation nuclear thermal propulsion technology ...
Atmosphere-breathing electric propulsion, or air-breathing electric propulsion, shortly ABEP, [1] is a propulsion technology for spacecraft, which could allow thrust generation in low orbits without the need of on-board propellant, by using residual gases in the atmosphere as propellant. Atmosphere-breathing electric propulsion could make a new ...
