Lightning Direct Effects Test System on Aircraft, High Current Physical Damage Testing System,Component ABCD

• Four individual current generators are used respectively or together by one main control system, to achieve the ABCD waves following an order defined by the operator.
• One coupling unit is adopted for each generator to avoid the mutual influence between the generators.
• 15’ color touch panel is adopted for easy and automatic operation.
• Optical fibre communication between the control desk and the generators, 5 control systems (one main control system and 4 individual control systems).
• Charging voltage, charging current can be set in A,B,C,D wave; Amplitude can be set for B and C wave; Time duration can be set for C wave.
• Wave A generator adopts digital crowbar circuit, which ensures the stable running and accurate trigger.

The aircraft is easy to be attacked by the direct lightning when it flies in the convective environment, which will generate high temperature, high pressure and strong electromagnetic force. This will cause some bad affection to the aircraft, such as burn, explosion, structural aberration, etc.
