Patent abstract
The bearings of aircraft angle of attack (AOA) vanes are susceptible to lightning strike damage, which causes fluting on the inner and outer races of the bearings and causes the bearings to generate friction, noise, and vibrations. To prevent the bearings from experiencing damage due to lightning strikes, the bearings, the shaft, and/or the mounting plate are configured to create an electric isolator to prevent the electric current from the lightning strike from passing through the bearings, thereby preventing the bearings from incurring lightning strike damage.
