|Issue Date:||29-Jul-2005||Citation:||Zhang, K.L., Chou, S.K., Ang, S.S., Tang, X.S. (2005-07-29). A MEMS-based solid propellant microthruster with Au/Ti igniter.

ScholarBank@NUS Repository. https://doi.org/10.1016/j.sna.2005.04.021||Abstract:||A solid propellant microthruster with Au/Ti igniter is demonstrated as an improved micropropulsion system for microspacecraft. The new design provides the microthruster with a high degree of flexibility, maneuverability and integration. Single microthruster and microthruster arrays have been successfully fabricated using standard microfabrication technologies. The propellant combustion process in the micro-chamber of the microthruster has been visually observed. Initial tests employing gunpowder-based solid propellants, have produced 2.11 × 10-5 to 1.15 × 10 -4 N s of total impulse and 2.68-14.65 s of specific impulse at sea level, and 3.52 × 10-5 to 2.22 × 10-4 N s of total impulse and 4.48-28.29 s of specific impulse in vacuum. The performance of the solid propellant microthruster with Au/Ti igniter is also compared with that of a solid propellant microthruster having a wire igniter. © 2005 Elsevier B.V.
