backblast
Rearward blast of gases to the rear ofrecoilless weapons, rocket launchersand rocket assisted takeoff units.

Cone shaped area in rear of a recoillessweapon, rocket launcher or rocket as-sisted takeoff unit which is dangerousto personnel.

bag, propellant
Fabric container that holds the propellingcharge for separate loading or semi-fixed ammunition. Usually made ofcartridge cloth, a special fabric that isconsumed without leaving a burningresidue.
bagloading
The loading of propellant into bags toform propelling charges for semifixedor separate loading ammunition.
ball Ammo nomen
1. Indicates a bullet for general use asdistinguished from bullets for specialuses such as armor-piercing, incen-diary, high explosive, etc. 2. Indicates asmall arms propellant which is oblatespheroidal in shape, generally doublebase propellant.
BALL, CELLULOSE-NITRATE
An item to simulate gunfire, for trainingpurposes.BALL, CELLULOSE-NITRATE: pOW-der filled.
ball ammunitionhlona~~r-piercing Small armS ammuni-
tion in which the projectile is solid. Itis intended for use against personnel,light material targets or for trainingpurposes
ballisticPertaining to ballistics
the motion of missiles.
ballistic coefficient
(which see) or
Thenumerical measure of the ability of a
missile to overcome air resistance. Itis dependent upon the mass, the diam.eter and the form factor (which see).
ballistic equivalenceSubstitution of a single perforated grain
with web of 1.23 to 1.28 times the webof a seven-perforated grain for pre-liminary interior ballistic calculationsis sometimes desirable. Since the as-
sumed grain gives about the same cal-culated results as the multiperforatedgrain, they are said to have ballisticequivalence.
ballistic limitThe minimum velocity at which a particu-
lar armor-piercing projectile is expect-ed to consistently completely penetratearmor plate of given thickness andphysical properties at a specified angle ●of obliquity. Because of the expense offiring tests and the impossibility of con-trolling striking velocity precisely, plusthe existence of a zone of mixed resultsin which a projectile may completelypenetrate or only partially penetrateunder apparently identical conditions,statistical approaches are necessary,based upon limited firings. Certain ap.preaches lead to approximation of theV,, Point, that is, the velocily at whichcomplete penetration and incompletepenetration are equally likely to occur.Other methods attempt to approximatethe VO Point, that is, the maximumvelocity at which no complete penetra-tion will occur. Other methods attemptto approximate the Vi,, Point, that is,the minimum velocity at which all pro-jectiles will completely penetrate.
ballistic missileSpecifically, any missile guided especially
in the ascending part of its trajectory,

but generally becoming a free fallingbody in the latter stages of its flightthrough the atmosphere. This missilecontains guiding devices, such as presetmechanisms, but it is distinguished from
a ~ided missile in that it becomes a freefalbng body, subject to ballistic reac-tions as it descends through the atmos-phere. Currently the term has a strongconnotation of a missile designed totravel outside, or in the outer reaches.of, the atmosphere before plunging to-ward its target. The German V-2, Po-laris, Pershing and Thor are consideredballistic missiles. cf: guided missile.
ballistic mortar
A heavy, short barrelled mortar, pendu-lum mounted, for determining the rela-tive power of explosives. A small sam-ple of a test explosive is placed in thedetonation chamber and a projectile islocated forward of the charge. Upon
●detonation the projectile is driven intoa sand bank and the mortar swingsthrough an arc. A marker records themaximum height to which the mortarrises on its arc. The weight of the testexplosive required to produce the samerise as 10 grams of TINT is determined,and the rating is the percentage result-ing from dividing 10 by the determinedweight and multiplying by 100. Thisfigure is called the TNT value.
ballistic pendulum
First reasonably accurate ballistic meas-uring instrument for determining pro-jectile velocity; described by BenjaminRobins before the Royal Society ofEngland in 1743. A bullet was fired intoa wood pendulum, and its velocity de.twmined by equating the expressionsfor tile momentum of the bullet beforestriking the pendulum and the momen-tum of the pendulum after receiving thebullet.
ballistic table
Compilation of ballistic data from which

ballistic waveAn audible disturbance caused by the
compression of air abead of a missilein flight.
ballistic weaponAny missile weapon, as a bomb, rocket,
projectile, or bullet,’ affected by ballis-tic conditions.
ballisticsBranch of applied mechanics which deals
with the motion and behavior charac-teristics of missiles, that is, projectiles,bombs, rockets, guided missiles, etc., andof accompanying phenomena. It can beconveniently divided into three branch-es: i?tte?io?’ ballistics, which deals withthe motion of the projectile in the boreof the weapon; extem”or ballistics,which deals with the motion of the pro-jectile while in flight; and twmind bal-hktzks, which is concerned with the &fectand action of the projectile when it im-pacts or bursts.
ballistic of penetration
That part of terminal ballistics whichtreats of the motion of a projectile as itforces its way into targets of solid orsemisolid substances such as earth,concrete, or steel.

Often capitalized. A smokeless propellantcontaining nitrocelhdose and nitrogly-cerin, used in some rocket, mortar, andsmall arms ammunition.

In a b~oad sense, an explosi!-e or oti?erlethal agent together with its containeror holder, which is planted ortbrovm byhand, dropped from an aircraft: or pro-jected by some other slow-speed device(as by lobbing it from a mortar), andused to destroy, dam.age, injure, O! kill.2. Anything similar to this object in
appearance, operation, or effect, as aleaflet bomb, smoke bomb, photoflashbomb, a bomb-like container or cham-ber, etc. 3. In specific senses: a. An aerialbomb; b. A nuclear bomb. Often called“an A-Bomb or an H-Bomb.” In sensel,‘bomb’ includes grenades, aerial bombs,infernal machines, mortar projectiles,etc., but does not include cannon pro-jectiles, torpedoes, aircraft rockets, ormines. Guided missiles, ballistic missiles,explosive robot planes and similar de-vices are, however, sometimes popularlyreferred to as ‘bombs’ or ‘flying bombs.’In sense 3-a, the word ‘bomb’ is oftenmodified by a designating attributive, asinarmor-piercing bomb, chemical bomb,conventional bomb, etc. The varioustypes of bombs are separately listed anddefined.

and also to its ammunition. The gunbore may be tapered throughout itslength or only in the muzzle section. Theprojectile which starts out aa a lightweight projectile of the larger calibermay be projected at hypervelocity in theform of a smaller caliber projectile ofnormal or heavy weight. The smallercaliber maintains a higher velocity thanwould the larger caliber (for equalweight pro j ectiles) because of loweredair resistance. For this reason the tap-ered bore is sometimes used for anti-tank weapons. Sometimes referred to as‘squeeze bore’ or ‘C,erlich gun,’ after itsoriginator.
