DEVICE TO BE DEPLOYED FOR THE EXTENSION OF THE EXHAUST NOZZLE OF A ROCKET ENGINE

摘要

The device consists of a frustoconical-shaped skirt formed by a stack of tube rings or coils welded to one another. The tube has a cross-section flattened in the direction of the stack and incorporates on the inside a pyrotechnic device. The pyrotechnic device generates sufficient pressure to increase the dimension of the tube in the direction of the stack. The effect of this pressure is to unfold the nozzle extension.
