Technical Description
The invention discloses a high‑temperature porous structural panel configured to reduce impingement noise generated by high‑speed jets striking solid launch or process surfaces. Noise attenuation is achieved by tailoring the pressure drop across the porous panel, governed by an empirical pressure‑loss relation linking fluid velocity, viscosity, density and panel resistances.
