Point fuze

Deep cavity projectiles contain an aluminum fuze well liner (some rounds on hand may have a cardboard liner), that also serves as a support for the HE filler. This liner is not to be removed. Insertion of a supplementary charge into the fuze cavity adapts the projectile for mechanical-type point fuzes and boosters. When deep-cavity projectiles are assembled with any authorized fuze, the data are the same as for the normal-cavity projectiles so fuzed. Deep-cavity projectiles may be shipped with closing plug (with or without supplementary charge) or with supplementary charge and mechanical-type fuze (Ref 40b, pp 9-10)... 

Fuze, Standard Contour. A point fuze having a standard shape, size and shape agreed upon for use with a certain group of artillery projectiles. Such fuzes may be interchanged without affecting the flight of the projectile... 

Chemical Rockets Rockets equipped with chemical warheads. These heads consist of thin-walled casings loaded with casualty or harassing gas or smoke. They may be adopted for point fuzes or base fuzes and have a burster extending well along the axis of the head from the fuze seat(Ref 2,p 9)(See also Ref l,pp 9 332)... 

Recently, L. Fuzes reported the method of "distinguished points (DPs)" for comparing the SEC chromatograms of two or more polymer samples (1). The sequential U and t tests were suggested in order... 

Typical APC-T (Armor-Piercing, Capped Tracer) Projectile, shown in Fig 1-8, consists of hardened steel monobloc body and cap of forged alloy steel. The AP cap is heat-treated to have a hard exterior and a relatively soft core. The softer core protects the hardened point from breakage by distributing the stress during impact and thus helps the penetration thru armor. Then the BD fuze functions to detonate a HE chge located in the cavity at the rear of the body... 

Fuze, Air Nose. A point detonating (PD) rocket fuze which uses the air stream to arm itself... 

Fuze, Nose. A fuze located in the forward end of a bomb, and some missiles, but this term is not applied to fuzes located in the forward end of an artillery projectile (See Fuze, Point)... 

Fuze, Point Detonating (PDF). A fuze located in the forward end (point) of a projectile and designed to be actuated by impact. There are also Dummy and Inert Point Detonating Fuzes... 

It is provided with manual safety and/or setting devices simulating those of a standard or proposed standard PDF. It may or may not be a ballistic match with the fuze it is supposed to represent and/or contains a small expl chge for realism or spotting purposes (Excludes Fuze, Point Detonating, Dummy)... 

Fuze, Point Initiating (PIF). A fuze which has the target sensing element in the nose of a missile (Usually refers to PIBDF ) (See next item)... 

Fuze, Point Initiating Base Detonating (PIBDF). A fuze with initiating components located in the forward end of projectile, while detonating components are located in the base of projectile. It is designed to be Activated by impact... 

Fuze, Range. Range at which projectile will burst when the fuze is set at a given time value in order to produce burst at a predetermined point in space (Ref 38b, p 128)... 

Fuze, Spitback or Fuze, Flashback. A fuze located in the forward part of a shaped charge munition. When initiated by impact it produces a detonation which is directed toward the element located in the base of munition and this, in turn, detonates the main explosive charge. The combination of point impact fuze and base element is referred to as point initiating base detonating" (PIBD) fuzing system...
