Q

M758

SAFE

Study These Flashcards
A

-FIRING PIN CANNOT CONTACT DETONATOR ASSEMBLY

-SAFE FOR HANDLING, LOADING, FEEDING, OR CHAMBERING

20
Q

M758

SETBACK

Study These Flashcards
A

-PISTON AND BODY ASSEMBLIES ARE FORCED TO THE REAR BY THE ACCELERATION OF THE PROJECTILE

-SETBACK SPRING IS COMPRESSED

21
Q

M758

INITIAL ARMING

Study These Flashcards
A

-PISTON SPRING PUSHES PISTON, FIRING PIN, AND RESTRICTOR FORWARD, ALLOWING ROTOR AND DETONATOR ASSEMBLY TO ROTATE

-CENTRIFUGAL FORCE PUSHES THE SELF DESTRUCT BALLS TO OUTWARD, LOCKING THE BODY ASSEMBLY TO THE REAR

22
Q

M758

ARMING COMPLETE

Study These Flashcards
A

-CENTRIFUGAL FORCE ROTATES THE ROTOR ASSEMBLY TO ALIGN THE FIRING PIN WITH THE DETONATOR

23
Q

M758

3 TYPES OF DETONATION

Study These Flashcards
A

DIRECT IMPACT- IMPACT PUSHES FIRING PIN INTO DETONATOR

GRAZING IMPACT- DUE TO IMPACT, PROJECTILE LOSES FORWARD VELOCITY, FREEING THE BODY ASSEMBLY, ALLOWING SETBACK SPRING TO PUSH THE DETONATOR INTO THE FIRING PIN

SELF DESTRUCT- PROJECTILE DOES NOT IMPACT, PROJECTILE EVENTUALLY LOSES ENOUGH FORWARD VELOCITY, FREEING THE BODY ASSEMBLY, ALLOWING THE SETBACK SPRING TO PUSH THE DETONATOR INTO THE FIRING PIN. BETWEEN 3,000M AND 4,000M
