Abstract
A passive caging system for use in gyro-stabilized sensor platforms and the like, employing a pneumatic dashpot in place of automatic caging gyro brakes, pin-locking devices, springs, fluid damped pistons, or air bladders. A pneumatic dashpot in combination with a normally closed solenoid valve provides effective damping of shock forces while the system is in the unpowered state. When power is applied to the system, the solenoid valve is open and unrestricted movement of the sensor platform is enabled.
