The present work focuses on plume interactions in a convergent Hall thruster cluster for thrust vectoring. The analysis is done through a numerical model, using a custom hybrid- PIC code with Monte Carlo Collisions for ion-neutral interactions. The setup consists in two thrusters positioned at 10cm separation, each with a 10° convergence angle. In order to provide thrust vectoring, the ion current is changed by ±20% relatively to nominal.

A combined simulation is compared with stand-alone simulations of the two thrusters.

The comparison shows not only the deflection of high-angle charge-exchange ions, but also deviations of the main plume. A non-axisymmetric divergence model is developed, showing total divergence on the convergence plane to be smaller than single thruster divergence, contrary to what would be expected.

Light refreshments will be served before the lecture
