|
 | Report represents the results of a study to determine the feasibility of using Laser Holographic Interferometry to detect flaws in Navy gas turbine engine turbine blades. The experimental work employed a continuous wave laser because of its ease of operation in laboratory work. The double-exposure holographic technique was able to detect all existing flaws regardless of the degree of surface erosion. High pressure, first stage turbine blades from a TF41 ... |

|
| The purpose of this study was to develop and upgrade aluminum containing coating systems for the protection of nickel and cobalt alloys used in gas turbine hot section components. A comprehensive investigation of modifying elements was undertaken and correlated with hot corrosion resistance and diffusional stability under blade and vane cycle conditions (1950 amd 2200F peak temperatures, respectively). The modifying elements and combinations evaluated were Co, Mn, Cr, Ta, Fe, ... |

|
| JP-5 fuels containing 0.040 and 0.0004 weight per cent sulfur were tested to evaluate their effect on the durability of turbine-blade materials. Specimens of 13 different superalloys and 20 different superalloy-coating systems were exposed in the Phillips Turbine Simulator. It was operated at 15 atmospheres pressure with gas temperature and velocity at the test specimens cycled from 1000-2000 F and 163-275 ft/sec by control of fuel flow to simulate conditions ... |

|
| The report describes the results of a program that has demonstrated the practical feasibility of radiation pyrometry for gas turbines. Several sensor heads capable of interfacing with the severe environments of advanced turbojets were tested at sensor head temperatures of 1000F. Two basically different configurations of high environmental temperature sensor heads were used to identify target areas on blades and collect radiation from each blade as it passes across the ... |

|
 | An experimental investigation is being conducted to evaluate the effect of very-low concentrations of sulfur in fuel on the durability of turbine-blade alloys when exposed under conditions simulating the environment in an aircraft-turbine engine operating in a marine environment. This has required development of a new turbine simulator, to increase productivity by simultaneous exposure of specimens and to improve precision by rotating specimens for uniform exposure in the high-velocity stream ... |

|
| Problem in current gas turbine construction is that of increasing the working temperature of the gas. As is known, this leads to increased efficiency, and a reduction in the size and weight of gas turbines. However, the design of high temperature gas turbines encounters serious difficulties in connection with the limited capabilities of the metal of elements in the flow-through portion to stand up under increased temperature potentials. The most ... |
