Air cloud lightning is electrostatic charge through the wires lead to the ground, so that the positive and negative charge and discharge phenomenon does not occur.
Airplane flight and ground contacts do not produce, install a lightning rod not only would not achieve the role of lightning, thunder on the contrary will lead the upper body, it is not installed on the aircraft lightning rod. Aircraft do not lightning, but lightning.
The aircraft are equipped with electrostatic discharge device, commonly referred to as discharge brush discharge brush about three fingers thick, by the tens of root very fine needle with a total resistance of the body is relatively very small. According to the principle point discharge, the discharge will be able to brush airplane housing accumulated amount of charge put into the atmosphere, thereby protecting the safety of aircraft.
When lightning current generated by aircraft, or aircraft and also the air, clouds friction generated static electricity discharge current through the brush will instantly released to the outside of the fuselage. Thus, the role of the conductor will not effect the formation of high-energy release energy aggregation process. On modern aircraft wing or tail are equipped with discharge brush.
Usually per aircraft flying 10,000 hours is likely to be struck by lightning once, but most of all because the chassis is a conductor, so these strong currents will flow smoothly over the wing or fuselage skin, leaving a small burn corrosion holes or gaps in the aircraft flight does not matter.
Modern aircraft closure shell is made of metal, such metal closed housing having an electromagnetic shielding effect, no matter how high the aircraft outside the Lightning, the passengers within the aircraft will be electromagnetically shielded protection, although the high voltage , but can not form a current, so it will not shock, the passengers are safe. In addition, modern aircraft landing gear tires with special conductive rubber, which can effectively make the landing gear hit the ground instantly put the body to relieve residual charge to avoid electric shock when the plane passengers.
However, the ability to release the brush discharge is limited, if the plane was hit by lightning high energy, and the discharge of these shares can not brush off the energy released in an instant, it will produce resistance effect, it may damage the operation of electronic equipment of the aircraft, even the breakdown of the body, resulting in a vicious accident. Although the likelihood of the occurrence of such incidents is very small, but after all, it exists.
