Abstract:
1. An apparatus for splitting and removing a shroud from an airborne vehicle, the apparatus comprising: a shroud that includes two components, longitudinally linkable one to another, and wherein upon being fastened one to the other, form said shroud with a lengthwise axis and an inner space, and having a base sector around a circumference of a bottom part of said shroud, and wherein said base sector is connectable to said airborne vehicle; and a fastening assembly for fastening said two components of said shroud one to the other, and wherein said fastening assembly is configured to be torn by stretching along a first axis of operation upon detonation of a pyrotechnic charge; and a piston assembly comprising a piston element operable by said pyrotechnic charge for providing a piston stroke along a second axis of operation and wherein said piston assembly is configured to disassemble upon completion of said piston stroke, and is configured for timed tearing of said fastening assembly and active removal of said two components of said shroud one from the other, in an essentially revolving motion and while tearing and moving farther apart said shroud from said airborne vehicle; and wherein said apparatus is characterized by— said fastening assembly configured, upon detonation of said pyrotechnic charge, to be torn on stretching and positioned at a distance and separated from said piston assembly; and by the first axis of said fastening assembly that is torn on stretching, and the second axis of said piston assembly that is disassembled upon termination of the piston stroke, wherein the first axis and the second axis are essentially parallel one to the other, while essentially in an orthogonal and radial direction of operation relative to said shroud's lengthwise axis.
