Abstract
In this paper, we consider the applicability of the high-voltage surface flashover on ferroelectric ceramics in pulsed plasma thrusters. We made a thruster prototype based of high-voltage submicrosecond discharge. The power of the thruster is ~50 W, operation frequency is a few hundreds Hz, discharge voltage is ~20 kV, and weight about 400 g. The material of the discharge unit is barium titanate contained ceramics. The obtained values of thrust lie in the range 2-28 μN⋅s. The obtained velocities of the ion component of the plasma flow are up to ~100 km/s.
