WebbA 2D dual pendulum thrust stand was developed to measure thrust vector of a Hall thruster without thermal effect. A thruster is mounted on a pendulum and gap sensors are mounted on the other. By measuring thrust from the displacement between two pendulums, a thermal drift effect is canceled out. Two crossover knife-edges enable the pendulums to …
