Captive volume device as a safe life monitor |
摘要 |
A captive volume device containing a small amount of solid propellant and a safe life indicator such as a colorimeter material or a differential pressure sensor. As the propellant deteriorates, it expends a gas which changes the color of the colorimeter material or causes the differential pressure sensor to alter its position, indicating that the propellant material is useless.
