  • Publication number: 20250101965
    Abstract: A pulsed-plasma thruster using an unbalanced theta-pinch includes a gas-puff generator, an ionization convergent-divergent nozzle, and an accelerating coil set. The gas-puff generator supplies a gas puff in a pulsed manner; and the accelerating coil set is arranged on a side of a throat of the ionization convergent-divergent nozzle. After the gas puff enters the ionization convergent-divergent nozzle, an electric arc is generated between the pair of electrodes of the ionization convergent-divergent nozzle so that the gas puff is ionized and forms a plasma plume, and the electrodes are utilized to drive the accelerating coil set to generate axially non-uniform magnetic fields, to accelerate the plasma plume. Based on this, the control of thrust force generation is simple and reliable, with high energy utilization efficiency.

  • Publication number: 20240337133
    Abstract: A multifunctional strengthened lock structure includes a case and a bolt control unit and a strengthened triangular latch unit arranged in the case. The bolt control unit includes an own-axis rotating plate, a first push plate, a second push plate, a butterfly plate and a first spring, a second spring, and a pressing member, and an arc arrestor. When a lock-cylinder rotating axle is rotated to close, the own-axis rotating plate is rotate to the closed position, and the second push plate is inoperable due to the butterfly plate being pushed to an idle position so as to serve as a blocking plate for the handle rotating axle, thereby achieving a dual-locking effect. A triangular latch includes a latching head, a rod pivotally connected to the latching head, a strengthening ring fit over the rod, and a strengthening screw fastened to the latching head and the rod.
