Colloid Thruster to Teach Advance Electric Propulsion Techniques to Post-secondary Students
<p>Colloid thrusters, and electrospray thrusters as a whole, have been around since the 1960s. When they were first developed, the high efficiency and fine thrust control was overshadowed by the high power requirement for such a low thrust that the system provides. This caused the technology to be …

The design, fabrication and testing of micro-fabricated linear and planar colloid thruster arrays
… for this new technological niche. Electrospray thrusters are space propulsion electric engines that take advantage of an electro-hydrodynamic effect known as Taylor cone to produce thrust. When this effect takes place, charged particles are expelled from the apex of a conductive liquid meniscus …

Numerical simulation of a single emitter colloid thruster in pure droplet cone-jet mode
… holds promise for these type of missions are colloidal thrusters. These thrusters are electrostatic accelerators which do not rely on gas ionization (plasma), are intrinsically small, and operate at low power levels, while having small plume divergence angles to avoid spacecraft (S/C) …

Progress in colloid propulsion
… deal of work was put into the development of the Colloid Thruster as an electric propulsion system for spacecraft. In spite of the effort by the end of the 70s the programs were stopped in the USA and Europe before any design had gotten to fly in space. An exhaustive study of the literature has …

Studies on the ion-droplet mixed regime in colloid thrusters
Colloid thrusters working with mixtures of ions and droplets are gradually becoming an alternative technology for space micro-propulsion needs in missions requiring high position controllability, compactness and low power consumption. The mechanics of the colloid thruster emission process are …

Design Principles and Preliminary Testing of a Micropropulsion Electrospray Thruster Research Platform
… technologies used for this purpose, electrospray thrusters offer performance that make them an ideal choice. Electrosprays offer high accuracy impulse bits at low power and high efficiency, and have low volume requirements. Design choice reasoning and preliminary testing results are presented for …
