New aircraft, such as electric vertical take-off and landing vehicles, are being developed to support advanced air mobility. This talk will address gaps and risks in the aerospace supply chain and discuss how to identify and develop resiliency approaches.
By cementing a strip of an elastomer to the smooth metal rim of the pulley and neoprene covered idlers providing suitable tension to the chain around the pulley, a positive reversible drive is accomplished more quietly and with less vibration.
