The Journal of Propulsion and Power is a bimonthly peer-reviewed scientific journal covering research on aerospace propulsion and power. The editor-in-chief is Joseph M. Powers (University of Notre Dame). It is published by the American Institute of Aeronautics and Astronautics and was established in 1985.
[6] As a knowledgeable and objective participant in supporting industry research and development, CPIAC assists sponsors in maximizing increasingly limited research and development funding by focusing on key propulsion system technology needs through workshops, symposia, technical assessments, and surveys.
The Advanced Propulsion Physics Laboratory is enabled by section 2.3.7 of the NASA Technology Roadmap TA 2: In Space Propulsion Technologies: [11] Breakthrough Propulsion: Breakthrough propulsion is an area of technology development that seeks to explore and develop a deeper understanding of the nature of space-time, gravitation, inertial frames, quantum vacuum, and other fundamental physical ...
Deep Space 1 had 178 pounds (81 kilograms) of xenon propellant, with a total impulse capability of 2.65 x10 6 Ns [5] and was capable of increasing the speed of DS1 by 7900 miles per hour (12,700 kilometers per hour, 3.58 km/s) over the course of the mission. [3] It used 2.3 kW of electrical power and was the primary propulsion for the probe. [4]
According to Edgar Choueiri magnetoplasmadynamic thrusters have input power 100–500 kilowatts, exhaust velocity 15–60 kilometers per second, thrust 2.5–25 newtons and efficiency 40–60 percent. However, additional research has shown that exhaust velocities can exceed 100 kilometers per second. [2] [3]
Power Management and Distribution (PMAD) covers the entire power system between the source or power generator and the load, which in this case is the transmitter. Studies were being conducted to determine sensible technologies this size and scope. All of the switches, conductors and converters were immense compared to current spacecraft.
There have been many versions of the JPL DE, from the 1960s through the present, [2] in support of both robotic and crewed [3] spacecraft missions. Available documentation is limited, but we know DE69 was announced in 1969 to be the third release of the JPL Ephemeris Tapes, and was a special purpose, short-duration ephemeris.
An arcjet rocket or arcjet thruster is a form of electrically powered spacecraft propulsion, in which an electrical discharge is created in a flow of propellant [1] [2] (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 ...
