Radial actuator and release mechanism
Abstract
Abstract A HOLLOW TUBE OR RADIAL ACTUATOR CONTAINING AN EXPLOSIVE CHARGE, OR A MEANS OF PRESSURING THE INTERIOR OF THE TUBE FROM AN EXTERNAL SOURCE, IS DEFORMED BY FLATTENING, INDENTING, OR FLUTING, SO THAT THE VOLUME OF THE TUBE IS SUBSTANTIALLY REDUCED. WHEN THE TUBE IS PRESSURIZED BY FIRING THE EXPLOSIVE CHARGE, OR BY AN EXTERNAL PRESSURE SOURCE, THE TUBE INFLATES, AND ATTEMPTS TO RESUME A CYLINDRICAL SHAPE. IN RESUMING A CYLINDRICAL SHAPE, THE SPLIT TUBULAR RETAINER IS EXPANDED RELEASING A AND PERFORMS A USEFUL FUNCTION. IN THE APPLICATION SHOWN IN THIS DISCLOSURE, THE TUBE IS SITUATED WITHIN A SPLIT TUBULAR RETAINER OF A RELEASE MECHANISM WHICH IS INDENTED TO MATCH THE INITIAL FLUTES, OR DEFORMATION OF THE ACTATOR. WHEN THE ACTUATOR RESUMES ITS CYLINDRICAL SHAPE, THE TUBE TRANSFERS FORCE TO AN EXTERNAL MECHANISM, PIN, OR DEVICE, WHICH WAS HELD CAPTIVE IN THE RETAINER.
