Mortar projectile propellant

Ribbon double-base propellant used in mortar projectiles with components (mass %) No. 3 nitrocellulose 58.5%, nitroglycerine 40%, cen-tralite 0.8% and others.

The red end must be assembled adjacent to the primer (Ref 42, p 86). Ignition cartridge is inserted into fin assembly ahead of the primer. The shaft, in turn, is screwed into the base of projectile, which is made either from pearlitic malleable iron or from steel. Propellant M9 [ See Vol 2, p C35, Table VI (Ref 44)] charge consists of several increments sealed in individual cellophane bags (usually four for 60-min mortars and up to nine for 81-mm weapons). The bags are placed either between or within the blades of fins. 

In Section 3 are described components used for initiating propellants in small arms ammunition and in artillery ammunition. Also included are some initiators for military demolitions and for pyrotechnic items. In order to understand more clearly the function of iniators in ammunition, cutaway views of complete rounds (which includes cartridges and projectiles) of "fixed" and "semifixed ammunition are given in Vol 1 of Encycl (Ref 43), p A385-L, under "AMMUNITION." Section 3 gives also description of initiation of propellant charges in mortars, together with cutaway views of 60-mm, 81-mm and 4.2-inch mortar rounds... 

Rocket Motors (Roketto Hasshaki) are devices designed to provide propulsive power (propel or launch) to a Bomb or Rocket Projectile of an inclined trough or barrel called Launchers One of such Rocket Motors is described and illustrated in the book of Tantum Hoffschmidt (Ref 7, p 172) under the title Rocket Launcher and Rocket Motor Model 10 . It is briefly described here under Rocket Launchers. They are also described in Ref 2, pp 120-1 Another Rocket Mortar (Type 4 Mk 1) is described here under ROCKET BOMBS as a device used to propel Baka Piloted Rocket Bomb (Ref 2, p 118)... 

Im another method a heavy mortar, firing at an elevation of 30 is used. The explosive is detonated by means of a slow fuse and propels a projectile weiring 15 kg. The distance to which this is thrown is measured. 

The Parsons/HoneyweU EDS design includes the removal of propellant from 105-mm projectiles and the propellant and ignition cartridge from 4.2-inch mortars in the PRR adjacent to the UPA (most of the 105-mm projectiles and 4.2-inch mortars do not contain propellant). In the design previonsly evaluated in the ACW I Committee report, this operation was to be performed remotely (NRC, 1999). The hazards to workers in the PRR are similar to those in the UPA, and the consequences of accidents are also largely the same. In the new design, munitions are handled by workers more often than in the previous design, which could increase the potential for accidents. 

Fireworks are articles that provide audible and visible pyrotechnic effects solely for entertainment purposes, although the term may be broadened to include civilian-use signals and flares. Projectile fireworks contain a charge of propellant, or they may be expelled from a mortar. For major displays. 

Moderately-sized and simply-built rockets, cardboard mortars, or integral parts of fireworks items that propel such fireworks or military signals into the air are always regarded as pyrotechnic components. Subminiature rocket projectiles and very small control rockets for steering missiles and spacecraft in flight may or may not be considered in this category.
