The maintenance of bearings and rod ends is critical for rotary and fixed wing aircraft. There is currently no indicator or feedback mechanism in place for the maintenance crew to determine the remaining life or state of the liner. NanoLab, Security Technology Systems, and New Hampshire Ball Bearing (NHBB, a division of Astro) will all play roles in the development of a wear sensor for the AS81820 (fixed wing) and AS81819 (rotary) line of bearings. Our goal is to implement our solution as a drop-in replacement for the current lining material, with no mechanical design changes to the bearing.


Apparatus for detecting and identifying a chemical species in an environment, the apparatus comprising: a plurality of carbon nanotubes arranged to form a network, the network comprising a plurality of inter-carbon nanotube junctions; a plurality of electrical contacts, each of the plurality of electrical contacts being connected to the network such that the anisotropic electrical characteristics of the network can be measured dynamically while the network is exposed to the environment; wherein the network possesses electrical anisotrophy such that the ratio of the number of inter-carbon nanotube junctions which must be traversed by current per length of the plurality of carbon nanotubes differs for different directions within the network along the path from one of the plurality of electrical contacts to another of the plurality of electrical contacts, and further wherein the electrical anisotrophy of the network changes when a chemical species is present in the environment.

ABSTRACT: NanoLab proposes to develop a non-contact data transfer device to replace slip-rings in rotating assemblies. The proposed device will offer up to 300 channels of secure data delivery across the rotating frame at speeds of 20khz or higher. Further this device will be able to handle multiple input types, including thermocouples, strain gauges, and other analog and digital sources. BENEFIT: Slip rings are widely used to carry data and power between stationary and rotating components. That said, they are a significant maintenance burden, and are limited in their ability to handle data. A novel solution is proposed that is non-contact (to reduce the maintenance burden) and capable of high data rate.

Disclosed is a media (such as a filter media) having one or more carbon nanotube (CNT)-containing layer. Each CNT-containing layer contains high temperature refractory fibers (e.g., staple quartz fibers and/or ceramic refractory fibers) that have melting temperatures greater than about 600 C. and in situ grown CNTs. Substantially all of the in situ grown CNTs have one end thereof associated with the fibers. This results in substantially all of the in situ grown CNTs extending away from substantially all of the fibers. Moreover, substantially all of the in situ grown CNTs are dispersed throughout the fibers. In one embodiment the media also includes one or more supporting layer. Each supporting layer contains high temperature refractory fibers that have melting temperatures greater than about 600 C., optionally bulk refractory fibers, optionally E-glass fibers, and optionally microglass fibers. The media can be tailored as a filter media to remove different size particles and have different dirt loading capacities depending upon the desire of the consumer.
