Abstract
A self contained jet perforator torch (10) for defining large holes (H) in workpiece (W) such as a large bomb, includes a plurality of ports (68) fluidically connecting a combustion chamber with a slot-like chamber (62). The ports and the slot-like chamber extend at an angle with respect to the longitudinal centerline of the torch whereby fluid exiting the torch contacts a workpiece at an angle (I) with a normal (N) extending from the workpiece.
Claims17
A self contained torch for forming large holes in a workpiece, comprising:
- a storage means for storing pyrotechnic material;
- a nozzle means for conducting fluid generated by combustion of the pyrotechnic material against a workpiece, the nozzle means including fluid path means for guiding the fluid in a cookie cutter pattern against a workpiece at an angle outwardly of the zone of contact between the fluid and the workpiece.
A nozzle for a self contained torch which is used on a workpiece, comprising
- a base block having a centerline;
- a plurality of first fluid paths extending through said base block at an angle with respect to said centerline and terminating within said base block;
- a second fluid path extending through said base block and being in fluid communication with said first fluid paths for receiving fluid therefrom and conducting that fluid out of said base block, said second fluid path extending at an angle with respect to said centerline and directing fluid exiting therefrom at an angle to a workpiece surface located adjacent to said base block.
A nozzle for a self-contained torch which is used in conjunction with a workpiece, comprising;
- a base block having a centerline and one surface adapted to be located adjacent to a workpiece;
- a fluid path means extending through said base block at an angle to the centerline and to said block one surface for conducting fluid against the workpiece at an angle outwardly and away from a zone of contact between that fluid and the workpiece.
A method of defining a large hole in a workpiece comprising steps of:
- causing cutting fluid to flow along a path having a hollow conical shape and forming a circular cutting zone upon intersecting a workpiece;
- and
- guiding the cutting fluid into contact with the workpiece to flow outwardly of the zone of contact.
