CONTAINER—An assembly that encloses and protects the canopy, suspension lines, and risers until the parachute is opened. Sometimes called the pack assembly. CONTAINER, HARDSHELL—A container that has a rigid plastic or fiber body with cloth end and side flaps, designed to withstand high wind-blast conditions; for example, the NES-8B parachute container and certain MBEU parachute containers. CONTRASTING COLOR—A color that stands out from its background. CONTROLLER DROGUE—A small para- chute that is used to extract the stabilizer drogue parachute. CONVOLUTION—Used in this manual as the protruding side or portion of a diaphragm. CORE OVERLAP—During suspension line manufacture, the insertion of an incoming core yarn that runs parallel to a running out yarn, which results in two core yarn ends protruding through the casing a distance of about 2 to 6 inches. These ends are normally cut off during final phase of parachute suspension line manufacture. CORDS, CLOSING—Made of type I nylon cord approximately 18 inches in length. They are used as an aid in the closing of the parachute container. CROSS BOX—A sewing pattern. CROWN—A cloth panel used to cover the peak of a vane-type pilot parachute. Also, the portion of the main canopy surface near the peak. CUSHION, SEAT—A square, cloth-covered pad designed to provide comfort and equipped with a slot to provide passage for the harness leg straps. CUTTER, PYROTECHNIC—A device that is operated by an explosive charge and is used to cut line or webbing, etc.; for example, a static line cutter. D-RING—A metal fitting shaped in the form of the letter D; for example, a D-ring on a harness connects to a chest-type parachute assembly by means of snap fittings. Also, a slang term for the ripcord handle. DART—A short, tapered seam. DELAYED RELEASE JUMP—A parachute jump in which the wearer purposely does not open the parachute immediately upon safely clearing the aircraft. DIAMETER—The greatest straight distance across a circle. Specifically, the greatest distance across a flat canopy, from skirt to skirt, measured when the canopy is lying flat. Used to designate the size of a flat canopy. DIAMETER, NOMINAL—The diameter of a circle that has the same surface area as a given parachute canopy. This measurement is used to allow comparison of all shapes (conical, spherical, etc.) of parachute canopies. DIAMETER, PROJECTED—The greatest distance between opposite points on the skirt hem when the canopy is inflated. The projected diameter is approximately two-thirds the diameter of a flat canopy. DIP—A line or group of lines passing through a group of lines. Also, a group of suspension lines not in proper continuity. See also TWIST. DISPOSITION—Instructions on what is to be done with or to an item. DOUBLE-W—A sewing pattern. DROP TEST—The release of a parachute assembly with a dummy load from an airplane, tower, or ejection seat for testing purposes. DRY LOCKER—A tower or compartment of suitable height that will satisfactorily air fully suspended parachutes. EJECTION SEAT—An emergency escape seat for propelling an occupant out and away from the aircraft by means of an explosive charge or rocket motor. EJECTOR BOARD—A small, rectangular board with rounded edges and a grommet in one end used on MBEU parachutes. It serves as a firm place for the pilot parachute to spring from during opening.
