Abstract
The present invention provides for cutting operations using linear thermite charges; the charges cut one dimensional or two dimensional geometric shapes; the invention is useful for structure entry or demolition.
Claims15
A linear thermite charge apparatus comprising:
- a. an elongated casing;
- b. an elongated volume within the casing, the elongated volume having a length;
- c. a thermite material disposed within the elongated volume, the thermite material having an elongated length;
- d. an initiator positioned along the elongated length of the thermite material, the initiator configured to instantaneously activate the elongated thermite material along the length of the thermite material;
- and
- e. one or more linear nozzles in communication with the volume and configured to exhaust the activated thermite material.
