ESPET – ElectroSpray Propulsion Toolkit

ESPET is a multi-scale engineering tool

Recently, the first electrospray thruster was launched and successfully operated in space—producing precision propulsion with very high electrical efficiency. This is accomplished by electrostatically extracting charged particles from low vapor pressure liquids, thereby generating an accelerated, electrically charged spray.

Our work supports efforts to adapt this highly promising form of space propulsion to small satellites such as CubeSats.  Electrospray thrusters are recognized as a highly promising technology for extending the capabilities and the mission of small satellites.  SSI is working to develop design software for NASA, called the Electrospray Propulsion Engineering Toolkit (ESPET), with the objective to accelerate the development of arrays of electrospray thrusters for increased thrust and thrust density.

ESPET is a multi-scale engineering tool that extends experimental and detailed high-level physics characterization of microfluidic components to full-scale ESP microfluidic network performance.

ABSTRACT

  • ElectoSpray Propulsion Emitter Array

    SSI, in collaboration with Busek Company, Inc., is developing the Electrospray Propulsion Engineering Toolkit (ESPET), for the design of microfluidic systems of electrospray emitter arrays and forecasting their performance. ESPET is a multi-scale model that extends experimental and detailed high-level physics characterization of microfluidic components to full-scale ESP microfluidic network performance.
