A method was developed for cutting a fabric structural member in an inflatable module, without damaging the internal structure of the module, using linear shaped charge. Lexan and magnets are used in a charge holder to precisely position the linear shaped charge over the desired cut area. Two types of charge holders have been designed, each with its own backing plate. One holder cuts fabric straps in the vertical configuration, and the other charge holder cuts fabric straps in the horizontal configuration.

This work was done by Matthew W. Maples, Maureen L. Dutton, Scott C. Hacker, and Richard J. Dean of Johnson Space Center; Nicholas Kidd and Chris Long of Jacobs Technology; and Robert C. Hicks of Barrios Technology. For further information, contact the JSC Innovation Partnerships Office at (281) 483-3809. MSC-24529-1
