A Self-Adaptive Resonant Device and its use for Noise Control in Turbo-Prop Aircraft
A Self-Adaptive device with two or more distinct resonances is described by means of analyses results and test results for a prototype. Application of the devices is made to a Vibro-Acoustic model of a turbo-prop aircraft showing the advantage of such a device compared to standard non-adaptive
Dynamic Vibration Absorbers for noise control. Non-linear transient dynamic analysis validate the basic concept, and the functionality is supported by experimental test results. Various design alternatives are discussed and illustrated by pictures.
