| Abstract: |
| Objective To study on the influence of plateau alpine environment on helicopter avionics system test, response and helicopter environmental adaptability evaluation method. Methods By analyzing the influencing factors of the plateau alpine environment on the helicopter avionics system, the evaluation index system was established; and the fuzzy comprehensive evaluation method was used to obtain the adaptability evaluation value of the helicopter avionics system in the plateau alpine environment. Results The plateau alpine adaptability of the helicopter can be divided into two first-level indicators and 12 second-level indicators. The weight of the plateau adaptability evaluation index was 0.7983, and the weight index of the alpine adaptability was 0.2135. The fuzzy comprehensive evaluation value of a helicopter's alpine adaptability was 0.7692, and the comprehensive evaluation of adaptability was good. Conclusion The special natural environment, topography and climatic conditions in the plateau and alpine regions will have a great impact on the testing and use of aviation equipment. The importance of aviation equipment and even environmental adaptability testing of weapons and equipment is increasing day by day. The fuzzy comprehensive evaluation method can effectively evaluate the adaptability of plateau alpine environment of helicopter avionics system and improve the test efficiency. |
