Design Technique of the Test Static for Large Curvature Composite Radome

Abstract

The radome is an important component that maintains the aerodynamic shape of the aircraft, makes the electrical property stable, and ensures flight safety. Composite is used in most aircraft radome in the world to reduce the weight of the aircraft. For the sake of safety, a static strength test was usually conducted on the radome to verify whether its strength and stiffness meet the requirements. In this paper, the load was treated equivalently, and a lever loading system of nonparallel force was put forward considering the characteristics of the large curvature of the radome structure and that it was difficult to apply load. All test cases were completed successfully, and the test results indicate that the test system works stably and reliably, and the strength and stiffness of the radome meet the design requirements.
