AP/HTPE Star-Charged Solid Rocket Motor

Structurally Safe Under Fast Cook-Off

Under fast cook-off conditions, post-ignition combustion pressure causes limited casing damage with no detonation, and the motor case remains largely intact.

Advantages

ignition delay time is linearly related to heating rate

varying heating rates did not significantly affect ignition temperature

motor case remained largely intact, with severe deformation and fragmentation near ignition site and longitudinal cracks
