May 2013 — Life Improvement of Plain Airframe Bearings by Preventing Contamination
Safe, Inc. has been awarded a Phase I SBIR contract to develop a physical shield to protect spherical bearings from abrasive particulates, such as sand and dirt. The shield will prevent much of the contamination damage that shortens bearing life on rotorcraft. The initial effort by Safe will be to design a shield that will minimize heat build-up, reduce maintenance costs in both labor time and materiel, reduce operation costs and time lost by increasing the lifespan and dependability of critical aircraft systems. The ultimate goal of this program is to develop a shield that will minimize the impact on assembly weight, on the flexural resistance, and on the overall bulk of the assembly.
