All interfaces to electronic equipment on aircraft (avionics) are required to tolerate the indirect effects of lightning transients. Designing protection against high levels of lightning transients for DC power input lines presents a unique challenge in that gas discharge tubes (GDT) may function in an undesired manner when installed on power lines. An alternate solution to GDTs is to cascade multiple...
Electronic equipment on aircraft (avionics) are required to be immune to the indirect effects of lightning strikes to the airframe. The indirect effects of lightning strikes to airframes fabricated with carbon composite material are more severe in level and duration than those to metallic airframes. Thus, to use existing avionics deigned for aircraft with metallic airframes on aircraft with composite...
GDTs are a very effective component to suppress high powered pulsed transients such as lightning. When designing per the datasheet, one would expect a component to operate within the specified ratings. This is not always the case. Some GDTs typically violate the impulse spark-over voltage rating. The authors have noticed a belief in the industry that this is normal for a GDT. GDTs can be found that...
Aircraft manufacturers are increasingly choosing to use Carbon Composite material for the design of their airframes due to its obvious advantage of reducing the weight of the aircraft. However, a disadvantage of this decision is the large increase in the lightning indirect effect levels to which avionics equipment are exposed. The typical method of protecting avionic interfaces from these transients...
