A DESIGN FOR A ROTARY MACHINE TO ASSESS THE FRICTION SENSITIVENESS OF EXPLOSIVES AND PROPELLANTS
Abstract
A machine for assessing the friction sensitiveness of explosives and propellants has been designed to operate at velocities up to 30 ft/s (10 m/s), with a maximum dead load of 300 lb (150 kg). This has been accomplished by allowing the peripheral face of a metal disc to act on a flat metal plate, the load being applied pneumatically. The motion of the disc is effected by means of a flywheel striking a movable latch. The prototype machine has successfully completed its initial tests. Load and velocity can be varied simply, and the time taken to perform the tests is less than with the modified pendulum machine upon which the action is based. Further proving trials will be needed before the use of the machine can be recommended as a standard test procedure.
