Scientists at Novosibirsk State Technical University (NSTU) have created a computational model that shows how hail impacts affect composite parts of an aircraft. This was reported by TASSsaid the university’s press service.
The press service quotes the author of the project as saying: “We have developed a computational model that describes the behavior of a hailstone when it hits a composite panel: the hailstone breaks and we immediately calculate the deformation inside the panel.” NSTU graduate student Tuan Le Viet.
The researchers simulated a series of impacts with different particle sizes and velocities on multilayer composite panels. In the future, it is planned to simulate the impact on high-risk areas (the nose of the wing) or the entire surface of the wing. The university stated that no previous studies had been conducted on the effects of a series of hail impacts on composite panels or on assessing residual strength after impact.
The university also noted that this model can also be used in the activities of enterprises in the aviation industry (research institutes, design bureaus). NSTU added that this can be used in designing aircraft structures, testing and researching the strength of composite materials.
Before that, Russian scientists import changed composite for aircraft.
Previously reportedthat birds hit Russian planes more often.
