Bird and hail stone impact resistance analysis on a jet engine composite air inlet

Original language description

The paper describes the approach for the design of a jet engine composite air inlet for a new generation of jet trainer aircraft from the perspective of airworthiness requirements regarding high-speed impact resistance. Validated numerical simulation was applied to flat test panels. The final design was optimised and verified by validated numerical simulation and verified by testing on a full-scale demonstrator. High-speed camera measurement and NDT (non-destructive testing) results were used for verification of the numerical models.The test results of flat test panels confirmed the high durability of the composite structure during inclined high-speed impact with a near-real jet inlet load boundary condition. Owing to the sensitivity of the composite material on technology production, the results are limited by the material used and the technology production. The application of flat test panels for verification and tuning of numerical models allow optimised final design of the air inlet and reduce the risk of structural non-compliance during verification tests. Numerical models were verified for simulation of the real composite structure based on high-speed camera results and NDT inspection after impact. The proposed numerical model was simplified for application in a real complex design and reduced calculation time.
