Kathryn's Report: Cessna T206H Turbo Stationair

2020-8-18The compressor thrust collar radial holes were clear there was no evidence of scratches scoring or galling of the end surfaces and no evidence of rubbing on the compressor backplate seal bore There was no scoring or worn face areas on the compressor inboard thrust bearing The compressor back plate was corroded from heat and water exposure

OE Parts vs the Aftermarket

Many of your customers believe that OEM parts are better than aftermarket parts We wanted to dispel some of the myths once and for all Without getting into the mud about which brands are better It is important to note that not all parts are created equal and this includes both aftermarket and OE replacement parts

2002 NASA SBIR STTR Abstract Archives

For linear systems the problem has been solved in recent literature however failures when they occur can cause excursions into nonlinear regimes The primary thrust of this research would be to extend the results in nonlinear control theory to accommodate actuator failures in aircraft POTENTIAL COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)

Thrust Bearing Failure Prevention Analysis

2020-8-19Crankshaft thrust bearings provide a fore/aft gap-control for axial movement (or endplay) of the crankshaft These thrust bearings are located at a specific main bearing location generally at the center main or rear main depending on engine design A thrust bearing is either integrated with a specific main bearing assembly or independent of the main []

Bearing failure and how to prevent it

The bearing is at the heart of all rotating equipment and the condition of the bearing often reflects how well a machine is running Sometimes however bearings fail In these cases what's the first thing you should do? Get a basic understanding to assess simple failure situations Bearing
