Nano-particle field extraction thruster funded by the Air Force brian wang July 9, Funded by the Air Force, Brian Gilchrist and his colleagues are developing a new type of thruster that uses nanoparticles as propellant. Much of the engine is etched directly onto a wafer-thin piece of silicon via micro-electromechanical systems technologies, known as MEMS, that are more commonly used in the semiconductor industry. Since the nanoparticles are charged electrostatically rather than ionized as in ion or Hall thrusters, greater reliability and efficiency can be achieved.
Carbon nanotubes CNTs are cylindrical structures of carbon atoms with diameters in the nanometer length scale and lengths of micrometers to centimeters.
Due to the strong chemical bonds between the carbon atoms, CNTs have extraordinary mechanical strength that is many times stronger than steel or other industrial fibers. Since they are structurally equivalent to rolled up sheets of graphene, they also have outstanding electrical and thermal conductivity.
They use the vapor-liquid-solid catalytic chemical vapor deposition process which allows for control of CNT properties, including height, density, diameter, and alignment.

|Conventional Weapons - Atomic Rockets||Lifetime[ edit ] Ion thrusters' low thrust requires continuous operation for a long time to achieve the necessary change in velocity delta-v for a particular mission. Ion thrusters are designed to provide continuous operation for intervals of weeks to years.|
Commercial applications are wide ranging. CNTs are used in composites for structural materials, sports equipment, yachts, armor vests, aerospace components, automotive parts, flame retardent materials, spark protection, lightning protection etc.
CNTs are used in battery electrodes, sensors and diagnostics, microelectronics, solar photovoltaics, filtration, etc.Carbon nanotubes (CNTs) are cylindrical structures of carbon atoms with diameters in the nanometer length scale and lengths of micrometers to centimeters.

Nanoparticle Electric Propulsion for Space Exploration Thomas M. Liu1, Louis D. Musinski2, Termed the nanoparticle field extraction thruster (nanoFET), this highly integrated propulsion concept is a high efficiency, variable specific impulse engine type that can be using three different types of carbon nanotubes.
V to kV.
An ion thruster or ion drive is a form of electric propulsion used for spacecraft r-bridal.com creates thrust by accelerating positive ions with r-bridal.com term refers strictly to gridded electrostatic ion thrusters, and is often incorrectly loosely applied to all electric propulsion systems including electromagnetic plasma thrusters.
. Carbon Nanotubes for Nano-particle Field Extraction Thruster Using carbon nanotubes as propellant for nano-particle field extraction thrusters Stefan Seuleanu Introduction Carbon nanotubes have been a research focus for more than two decades due to.
Historically, the first approach has been increasing the exhaust velocity by inventing more and more powerful rocket engines.
Unfortunately for the anti-nuclear people, chemical propulsion exhaust velocity has pretty much hit the theoretical maximum. A fullerene is an allotrope of carbon in the form of a hollow sphere, ellipsoid, tube, and many other r-bridal.comcal fullerenes, also referred to as Buckminsterfullerenes or buckyballs, resemble the balls used in association r-bridal.comrical fullerenes are also called carbon nanotubes (buckytubes).
Fullerenes are similar in structure to graphite, which is composed of stacked graphene.
