PhD research: Experimental work, involved the design/fabrication and implementation of Langmuir probes to provide internal diagnostics of a 1kW electrothermal arcjet : Chief Technologist/Principal at . The complete arcjet system consists of the arcjet thruster, the fuel supply unit and the power supply electronics. This power supply transforms the 28 VDC from the satellite power bus into the W maximum current regulated arcjet power. This electronic module with an efficiency of 93% is designed by Dr. K. Meinzer from AMSAT DL, who is also. Carl Book, Mitchell Walker, “Effect of Anode Temperature on Hall Effect Thruster Performance,” Journal of Propulsion and Power, Vol Number 5, .

The group has been working on the technology since They first developed a two-channel thruster, the X2, before the more powerful X3 was created. The X3 thruster team said it broke records of generating maximum power output during recent testing at the Genn Research Center of NASA in Ohio. Chemical-reaction monopropellant rockets. For monopropellant rockets that depend on a chemical reaction, the power for the propulsive reaction and resultant thrust is provided by the chemical is, the energy needed to propel the spacecraft is contained within the chemical bonds of the chemical molecules involved in the reaction.. The most commonly used . The near field plume of a 1 kW class arcjet thruster was investigated using electrostatic probes of various geometries. The electron number densities and temperatures were determined in a simulated hydrazine plume at axial distances between 3 cm ( in.) and 15 cm ( in.) and radial distances extending to 10 cm ( in.) off centerline. A working ion thruster was built by Harold R. Kaufman in at the NASA Glenn Research Center facilities. It was similar to a gridded electrostatic ion thruster and used mercury for propellant. Suborbital tests were conducted during the s and in , the engine was sent into a suborbital flight aboard the Space Electric Rocket Test 1.

  Electric propulsion is a rather mature and reliable technology which is expected to soon become a standard propulsion for orbit and attitude maneuvers and control. Research, testing, and development span several space applications, with a special attention to micropropulsion.   Vol Issue 3, May Special Issue: Perspectives on Thermal Plasma Research for Industrial Applications; Dedicated to the memory of Professor Joachim Heberlein.

An arcjet rocket or arcjet thruster is a form of electrically powered spacecraft propulsion, in which an electrical discharge (arc) is created in a flow of propellant (typically hydrazine or ammonia).This imparts additional energy to the propellant, so that one can extract more work out of each kilogram of propellant, at the expense of increased power consumption and (usually).

To see how this is possible, consider the Arcjet thruster research and technology book distributions of tem­ perature and density at some cross section of the Size: KB. Another potentially viable electrothermal propulsion system is the arcjet thruster.

This propulsion system relies upon a centrally located cathode surrounded by an anode; a high voltage electric field is generated between the cathode and anode, while the propellant is injected between the two electrodes (Jordan, ).

In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters use a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the -effect thrusters (based on the.
