ABSTRACT:
There is disclosed an improved upper-stage rocket motor/engine assembly of the type which comprises in combination with the basic rocket engine/motor and rigid or fixed nozzle thereof one or more telescoping nestible-extendible truncated cone-shaped collars of rigid structural form, and a further deployable perimetrically attached skirt formed of sheet metal or the like which is pleat-folded inwardly from an initial truncated cone-shaped configuration into a generally planar configuration. The assembly when inoperative is stowed within the basic engine/motor and nozzle profile; but in association with engine/motor firing the extendible components thereof are progressively deployed in accord with an improved technique to provide the desired extended length and plume exiting diameter/area nozzle effect.
