Paper Abstract

Magnetic Bearings are being used to isolate sensors from the severe vibrational, thermal, and frictional environments encountered on airborne systems. Technology developed by Aura Systems in the design and fabrication of magnetic suspension systems shows great promise for the stabilization of airborne sensors. This paper will cover the performance results of the Magnetic Gimbal Fabrication and Test (MGFT) project, which consisted of fabrication and performance testing of a single axis magnetic bearing. The MGFT results show LINE OF SIGHT (LOS) accuracy from 3 to 8 μrad with an angular disturbance of 48 rad/sec achieving vibration rejection of up to 79 dB. Also included is the description of the Advanced Missile Technology (AMT) project, which consists of fabrication and test of a single axis magnetic arc bearing for a small diameter missile. The AMT shows the capability to miniaturize the magnets and to provide extremely low friction under thermal loading. After proving the performance of magnetic bearings with the MGFT program a vast reduction in the size and weight of the magnetic bearing and associated electronics has been achieved while maintaining performance as demonstrated in the AMT.
