Abstract :
In this study, reactive B/Ti multilayer igniters were investigated for the noncontact ignition of a micro solid rocket array thruster in vacuum. When current is supplied to the B/Ti multilayer igniter, the chemical reaction: 2B + Ti rarr TiB2 + 1320 cal/g occurs, and high temperature plasma is discharged to a distance of several millimeters or more. The B/Ti multilayer igniters with 3 sizes were fabricated, and tested in 6 configurations of solid propellant. Although one rocket with ignition charge was ignited successfully, the noncontact ignition of the solid propellant was not achieved.
