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. The shear plate assembly focuses force in the optimal leg locations for efficient shearing of the frangible portions. The separation device 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.
Claims19
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 an expansion cavity is formed between at least one attachment portion and at least one frangible portion;
- with at least one inflation device located within the expansion cavity;
- further comprising at least one shear plate assembly which transfers and focuses inflation device force to, or near the desired fracture plane of at least one frangible portion.
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 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;
- further comprising at least one shear plate assembly which transfers and focuses inflation device force to, or near the desired fracture plane of at least one frangible portion.
