Pyrotechnic Composition

Question 1

Definition of pyrotechnics composition?

Answer 1

A pyrotechnic composition is a chemical or micture of chemicals which when ignited, burns at a controlled rate, liberating energy and producing a reaction which can be converted into the desired effect.

Question 2

What are the 4 pyrotechnic effects?

Answer 2

Heat
Light
Sound
Smoke

Question 3

Name the pyrotechnic groups.

Answer 3

Illumination
Smoke
Signalling
Delay
Tracer
Incendiary
Priming
Simulators
Pyro mechanisms

Question 4

Explain delay compositions?

Answer 4

A device that provides a time delay for a burning train of inflammable composition between events.

Milliseconds to several minutes

Question 5

Incendiary compositions must have what?

Answer 5

Must have a high burn rate to produce the required effect. However, heat must not be liberated too quickly.

Two basic groups
spontaneously burning metals
Combustible fluids

Question 6

3 typical priming compositions

Answer 6

Potassium nitrate
Powdered silicon
Sulphuless mealed gun powder

Question 7

Simulators are used to?

Answer 7

Simulated battfield noise and effects during training.

Question 8

Definition decribing the makeup of pyrotechnic composition?

Not the definition of a pyrotechnic.

Answer 8

The basic pyrotechnic composition consists of intimate mixtures of solid fuels and oxidants together with various additives to ensure burning at a uniform and predictable rate.

Question 9

What is the role of a first fire composition.

Answer 9

Acts as a booster between the low energy output of the initiator and the main composition.

Question 10

Additives in pyrotechnics colours

Red

Yellow

Green

Blue

White

Answer 10

Red strontium nitrate

Yellow sodium nitrate

Green is barium nitrate and chlorate

Blue is copper carbonate chloride oxychloride

White is various nitrates

Cool fact dyes can also be incorporated sig illum
