The thruster investigated features an emitter array of 480 emit-ter tips per square centimeter and a 1 cubic centimeter propellant tank with an entirely Session : Electrospray Propulsion (c) The advances in micro-manufacturing technologies allow for e cient clustering of a large number of emitter tips on a small surface, potentially to the point of competing with plasma thrusters (ion or even Hall) in achievable current density. Affiliated Lab/Research Group: Space Propulsion Laboratory The project is situated in the context of electrospray thruster engineering. However, the ΔV output of the propulsion system is limited by the lifetime of individual electrospray thrusters. where γ is the surface tension of the liquid, G is the emitter-to-gate separation, ε o is the electrical permittivity of free-space, and ID and OD are the inner and outer diameter of the emitter, respectively (Fig.  Laboratory Demonstration of a Staging system for electrospray thrusters application tends to be a low-volatility ionic based in!
