A buildup of static electricity is usually harmless, resulting in only small shocks. But in some cases it can be deadly. Discover the danger static electricity poses for helicopters and their crew.
- Static electricity is the buildup of electrical charge on objects.
- Static electricity is a hazard for rescue helicopters.
- When helicopter blades rotate they rub against dust particles in the air and become charged.
- A winchman uses a static line to neutralize the charge from the helicopter.
Shocking and hair-raising, static electricity is a curious phenomenon.
Static electricity is a buildup of electrical charge on objects, often due to friction.
Unlike dynamic electricity, which we use in our homes, static electricity builds on insulators - materials that do not readily conduct an electrical charge.
When the insulator is brought close ...
