NASALangley Research Center, HamptonA/irigina, has used the m+p international VibControl system for acoustic control at their progressive wave tube test facility for years. Tested spectra include uniform, two cases of pink noise, three cases of narrow-band random, a simulated launch payload bay environment for an expandable launch vehicle, and a simulated external acoustic load for the aft section of a reusable launch vehicle. |
