Download or read book Friction and Wear Under Fretting Conditions of Materials for Use as Wire Friction Dampers of Compressor Blade Vibration written by Max A. Swikert and published by . This book was released on 1968 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Friction dampers are required to reduce the magnitude of vibrational stresses in high-aspect-ratio blading of compressors for advanced aircraft turbine engines. Fret ting Is a common problem with all types of friction dampers. Fretting experiments with simulated wire-lace blade damping were conducted with Inconel 600. Experiments were run with or without oxide coatings In contact with maraging steel. Although two methods were used to form the oxide, high friction and low wear occurred with both. Further wear experimentation with oxidized material rubbing against itself showed that friction and wear were decreased by operation at a higher temperature (500 deg F or 260 deg C).

Download or read book Development of Improved Abradable Compressor Gas Path Seal written by W. P. Jarvi and published by . This book was released on 1978 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of fiber metal systems were evaluated by rig testing in comparison with the base line material, FM-521 - a 19% dense, Haynes 188, 8 micron fiber metal - which is the standard production material used for the highest temperature compressor blade tip seals in the P and WA F-100 engine. A range of densities and strengths of alternative materials were evaluated including Haynes 188, FeCrAlY, NiCrAlY, and FeNiCrAlY employing fiber diameters in the range of 8 - 23 microns with fiber aspect ratios in the range of 45 - 80. Rig tests employed were high speed rub testing, cyclic static oxidation, cyclic dynamic oxidation, and hot particulate erosion. These data were supplemented with measurements of mechanical, thermal, and chemical properties. The best material tested was a 20.5% dense FeNiCrAlY fiber metal employing 17 micron fibers. This had at least equivalent abradability and improved oxidation and erosion resistance in comparison with the base line material.
