Intro To Explosives Flashcards
What are the three types of explosions.?
Nuclear mechanical chemical.
Name four elements of the positive pressure phase.
Pushes away. more powerful. faster. shorter in duration.
Name four elements of the negative pressure phase.
Fills the void. not as strong. slower. longer in duration.
Alchemical explosive compositions must contain what.
Fuel and oxidizer.
Name and explosive mixture and how it’s blended.
Blackpowder. mechanically blended
Name explosive compound and how it’s bonded.
Nitroglycerin. molecularly bonded.
What do additives like oxidizers and fuels do when added into an explosive.
They are added to create a special effect.
What is the name of the phenomenon that causes shaped charges to work.
Monroe effect.
Characteristics of the mechanical explosion that do not apply to chemical explosion.
Mechanical explosions require a container.
List the primary effects caused by the detonation of a chemical explosion:
Fragmentation. incendiary/thermal. blast pressure.
Describe the blast pressure effects associated with the detonation of an explosive
Positive and negative pressure.
List the minimum components required in a chemical explosives.
Fuel and oxidizer.
Low explosives are said to deflagrate or _______ rather than detonate.
Burn.
Why is a blasting cap used with high explosives trains?
It starts the shock wave.
What is the difference between a high and low explosive train.
Low deflagrates, high detonates.
