Flourescence Coding of Plastics fo r Enhanced Identification and Sorting
Not Available The extreme conditions that a high performance fighter aircraft must operate in lead to harsh vibroacoustic environments that the various aircraft electronics and the precision optics of an airborne laser weapon must survive. Standard practice for reducing the effects of these environments is to beef up the support structure or use acoustic blankets, both of which impose severe weight penalties. CSA Engineering proposes to develop active acoustic suppression technologies, which have the potential for good performance without the severe weight penalties, for application to high performance fighter aircraft. The suitability of the numerous acoustic suppression techniques will be performed for fighter electronics/weapons bays. Structural-acoustic simulations of these bays integrated with models of the host aircraft will be used to evaluate performance levels of these acoustic suppression designs. The predicted attenuation levels, and the physical practicality and modularity of the designs will be selected for further evaluation in a hardware demonstration. In the demonstration, a mockup of the electronics bay will be constructed and tested for acoustically induced vibration. The measured acoustic and vibration reduction with the acoustic suppression applied will provide an indication of levels of improvement that are realistically achievable.
