Fuze Terminology

Question 1

FUZE

Answer 1

A device with explosive components designed to initiate a firing train or detonation in Ordnance.

 Buy an action such as hydro static pressure, electrical energy, chemical, impact, mechanical time, or a combination of these. a non electrical device designed to initiate an explosion in Ordnance by an action such as continuous or pulsating electromagnetic waves, acceleration or deceleration forces, or piezoelectric action.

Question 2

FUZE,ALL-WAY

Answer 2

And impact fuse designed to function regardless of the direction of impact commonly called in “all way acting fuze”

Question 3

FUZE, ANTI DISTURBANCE

Answer 3

fuse designed to become armed after impact, or after being in placed, so that any further movement or disturbance would result in detonation.

Question 4

FUZE, ADAPTER

Answer 4

An adapter that is used to connect a fuse to Ordnance

 allows for a smaller-diameter fuse to be used in a larger-diameter fuse well

Question 5

FUZE, BURST ADAPTER

Answer 5

An adapter that is inserted into chemical or bursting smoke munitions at the factory so that the fuse can be inserted later.

Question 6

ARMING PIN

Answer 6

A safety device which is inserted in a fuse to prevent the arming cycle from starting.

Question 7

PYROTECHNIC DELAY

Answer 7

A pyrotechnics device added to a fire system which transmits the ignition flame after the predetermined delay.

Question 8

SAFETY

Answer 8

A locking or cut-off device that prevent soreness from being fired accidentally

Question 9

SAFETY CLIP

Answer 9

A clip specifically designed to prevent pressure being applied to the upper portion of a pressure actuated ordinance.

Question 10

SAFETY PIN

Answer 10

A device designed to fit the mechanism of a fuse and to remain with it throughout transportation.
**presence of the safety device prevents arming or functioning of the fuse. The device is intended to be removed by the user just prior to employment

Question 11

FIRING PIN

Answer 11

Pain in a firing mechanism that strikes the primer.

 Explosive to initiate an explosive train

Question 12

VANE

Answer 12

a portion of a fuse that turns due to movement of the air or water through them to a line fuse components during the arming cycle

Question 13

UNARMED

Answer 13

The condition of a fuse (or other firing device) in which the necessary steps to put it in condition to function have not been taken

Question 14

GRAZE SENSITIVITY

Answer 14

The ability of a fuse to be initiated by grazing the surface at a glancing angle (80 to 90 degrees from the normal)

Question 15

FUZE SAFETY

Answer 15

two terms commonly used to describe built-in safeties designed to prevent premature functioning at the time of employment, and to provide safety and transportation for EOD.

 A. Bore safety
 B. Detonator safety

Question 16

FUSE SAFETY / BORE SAFETY

Answer 16

Applicable only two fuses used in projectiles with rockets.
refers to the provision of means to prevent functioning while in the bore of a gun or launch tube such fuses are said to be Bore safe.

Question 17

FUSE SAFETY / DETONATOR SAFETY

Answer 17

Relates to fuses for any application.

 refers to the provision of means to prevent functioning of the succeeding elements of the explosive train if the detonator functions while the fuse parts are in the safe position. Such a fuse is said to be detonator safe.

Question 18

ARMING DEVICE

Answer 18

device designed to perform the electrical and / or mechanical alignment necessary to permit the initiation of an explosive train
