Abstract
A separation device assembly with efficiency that allows for multi-fault-tolerance. The separation device assembly comprising an inflation device that applies force to a shear plate assembly which in turn applies focused force to a frangible portion which has a groove or stress riser to facilitate fracturing. The assembly further comprising a means for limiting excess movement after fracture so that residual energy from the inflation device is applied to non-fractured portions of the assembly.
Claims22
A separation device assembly comprising:
- A separation device having at least two attachment portions, at least one frangible portion, and at least one movement stopping element;
- the attachment portions being arranged to fixedly connect to at least two separate structural components, with the attachment portions being joined to each other through at least one frangible portion,
- with at least one movement stopping element positioned as to confine the post-fracture movements of at least one frangible portion to between one tenth to sixty times the elongation limit of the fracture plane material;
- wherein at least one frangible portion contains a groove or stress riser to facilitate fracturing;
- wherein an expansion cavity is formed between at least one attachment portion and at least one frangible portion;
- further comprising, at least one inflation device located within the expansion cavity.
The separation device assembly of claim 11, wherein the inflation device is configured with a recurved groove along its axis.
A method of separating portions of a structure at all locations along a three dimensional separation assembly, the method comprising:
- an inflation device deposited inside an expansion cavity used to fracture frangible portions, and wherein at least one frangible portion contains a groove or stress riser to facilitate fracturing, and
- also providing a stopping means which confines post fracture movements of any frangible portions to between one tenth to sixty times the elongation limit of the fracture plane material.
