摘要: A noise suppression system for a jet engine, the having substrate formed of open cell material, layer microporous material covering at least portion one surface substrate, substantially non-porous an opposite and pressurized air source providing to substrate. The are configured define inner (14) inlet (12) engine. is communicated from through into so as provide less turbulent airflow (23) along (12), thus mitigating generation.
