ATTACK ANGLE SHAFT MOUNTING SYSTEM, ATTACK ANGLE SHAFT FOR AN AIRCRAFT, AND METHOD TO PREVENT LIGHTNING DAMAGE TO AN ATTACK ANGLE SHOULDER BEARING.

摘要

aircraft angle of attack (aa) paddle bearings are susceptible to lightning damage, which causes fluctuation in the inner and outer bearing grooves and causes the bearings to generate friction, noise and vibration. To prevent bearings from experiencing lightning damage, the bearings, rod, and / or mounting plate are configured to create an electrical insulator to prevent lightning current from flowing through the bearings, thereby preventing the bearings from incurring. in lightning damage.
