Web3 mrt. 2024 · The engine developed by NASA and the US Air Force is composed of three concentric channels of acceleration. The X3 ion thruster can operate with an electric power of up to 200 kilowatts, which is enough energy to power a small village on Earth. This allowed it to set push records for a Hall-effect thruster : 5.4 Newton in a test run in 2024. WebIn addition, it overcomes the erosion and lifetime problems that occur in both the Hall Effect thrusters and gridded ion thrusters as there is no contact between the plasma and any electrodes. However, although practical research on this technology has begun, the theory around the existence of a double layer has been much debated on. Web27 mei 2024 · A Hall Thruster, initially developed in Russia, is a device that employs electric and magnetic fields to ionize propellant gases such as Xenon to produce thrust.
