What is detonating cord made of?
Detonation Cord consists of a high-explosive (either PETN or RDX) core wrapped in a reinforced, waterproof, olive-drab plastic coating that transmits a detonating wave. It is used as a detonating agent, a priming agent or alone as an explosive charge.
What does detonating cord look like?
Detonating cord (detonating fuse) resembles safety fuse but contains a high explosive instead of black powder. The first successful one, patented in France in 1908, consisted of a lead tube, about the same diameter as safety fuse, filled with a core of TNT.
What are detonating cords used for?
Low-yield detonating cord can be used as a precision cutting charge to remove cables, pipes, wiring, fiber optics, and other utility bundles by placing one or more complete wraps around the target. Detonation cord is used in commercial boilers to break up clinkers (solidified coal ash slag) adhering to tube structures.
What is meant by detonating?
: to explode with sudden violence. transitive verb. 1 : to cause to detonate detonate a bomb — compare deflagrate. 2 : to set off in a burst of activity : spark programs that detonated controversies.
What is a detonating gas?
A gaseous mixture that explodes violently on ignition (as two volumes of hydrogen with one volume of oxygen, forming water).
Where is Semtex made?
Czech Republic
2.1. Semtex 1H is a plastic explosive produced by Explosia Company, Czech Republic.
What is a mechanical explosion?
Overview. A mechanical explosion is a rapid, uniform expansion of a gas that takes place without chemical reaction. The process is very rapid such that heat and mass transfer to or from the expanding gas can be considered negligible.
How do you know if your engine is detonating?
Moderate to severe detonation could be noticed as engine roughness, vibration or loss of power and eventually engine damage. A pilot should always be looking for unexpectedly high Cylinder Head Temperatures (CHTs) or Exhaust Gas Temperatures (EGTs) which may be a sign that detonation is occurring.
What are detonating waves?
Detonation waves are shock waves that are sustained by the energy of the chemical reaction that is initiated by the shock compression. Depending on various conditions, the compression waves may telescope into a shock front and the shock front may develop into a detonation wave.
What is the formula of detonating gas?
2H2O2(l)→2H2O(l)+O2(g)
