Fuze arming and firing forces

Question 1

1. What is Newton’s first law?

Answer 1

Body at rest will remain at rest, body in motion will remain in motion

Question 2

2. What is Newton’s second law?

Answer 2

Relationship between mass, acceleration, and force vectors

Question 3

3. What is Newton’s third law?

Answer 3

For every action, there is an equal and opposite reaction

Question 4

4. How is energy categorized?

Answer 4

TYPE, FORM, and COMPONENTS

Question 5

5. What are the two types of energy?

Answer 6

Chemical
Electrical
Thermal - heat
Radiant
Mechanical
Acoustic

Question 7

7. What are the two type of chemical energy?

Question 9

9. What are the fuze arming principles?

Answer 9

Electrical impulse
Gas pressure
Pressure
Arming Delay
Arming Device
Bore Safe
Bore Riding Pin

Question 10

10. What is an arming delay?

Answer 10

A mechanical, pyrotechnic or electrical device to delay the start of fuze arming

Question 11

11. What is an arming device?

Answer 11

Designed to perform the electrical and/or mechanical alignment necessary to permit the initiation of the explosive train

Question 12

12. What is bore safe and bore riding pin?

Answer 12

Bore Safe: Type of fuze that has an interrupter in the explosive train that keeps a projectile from exploding until it clears the muzzle of the weapon

Bore Riding Pin: Safety pin which is held in place in the fuze while the projectile or rocket is in the gun barrel or launching tube. It is ejected from the fuze by the effect of centrifugal force or the spring action beyond the muzzle

Question 13

Components that create energy

Answer 13

Generator
Wind driven generator
Battery
Piezoelectric or Lucky
Capacitors

Question 14

How do objects receive electrical energy?

Answer 14

Some action or force provides it i.e. impeller, batteries/cell, aircraft, piezoelectric crystal

Question 15

What is a safety pin?

Answer 15

Device designed to fit the mechanism of a fuze and remain with it throughout transportation. Presence of a safety device prevents arming or functioning of the fuze. The device is intended to be removed by the user, just prior to employment.
