The lightning tests for the radome in Z11 helicopter of China

Abstract

The lightning protection tests which are simulated by power modulator and high voltage technology are used the radome system in the Z11 helicopter of China, it is presented in the paper. The radome system is composed of the radome, the lightning diverters, the air data probe and a long 0.5m metal structure which simulated a part of the helicopter body. The test facilities and the test results are introduced. Based on the tests, the radome system performance preventing lightning destruction is improved by optimizing the diverters. Finally, the optimized radome system passed the ground simulated lightning tests successfully by the Chinese CCAR27 (equal to FAR27) and the standard of lightning protection of aircraft HB6129-87(equal to SAE ARP 5416).
