Multifrequency Composite Analysis

DMA testing at actual frequencies from 0.1 to 30Hz can then allow us to extrapolate to 18,000rpm (300Hz) for a F1 engine or even to higher for ultrasonics. (We use a newer version of the apparatus which the Navy research depts used in the 1980s, so that the British submarines could not be detected by the Russian sonar detectors, by coating the top surfaces of the Subs with various polymer foams developed in the SW of the UK and at Holton Heath.
