초록

058410796 In accordance with the present invention, in an air vehicle having a turbo engine including an inlet which receives intake airflow and is defined by an inner surface and a D-nose of the turbo engine, there is provided an inlet liner for improved acoustic, anti-ice and drag performance. The inlet liner is provided with a permeable acoustic layer formed to attenuate sound and defines the D-nose. The inlet liner is further provided with a pressurized fluid injecting device. The pressurized fluid injecting device is in fluid communication with the ...
