 | A quad redundant digital FBW Control System for a highly unstable fighter aircraft has been developed and flight tested by MBB in a single seater F-104 G which had been modified as a CCV demonstrator. The CCV program was funded by the German MOD. From Dec. 1977 to Nov. 1981 a total of 118 flights has been conducted. During these flights the quadruplex system was successfully tested for five different ... |

|
| In order to summarize extensive research in self-lubricating bearings, porosity of powder metallurgy materials is analyzed with equations, graphs, and microphotos of both compacted and sintered metals of various densities used in plain slide bearings. The effects of increasing sintering temperatures from 200 C to 1000 C upon porosity and wear resistance in bearing metal are analyzed as related to speed of operation and bearing load. Permeability of porous bushings ... |

|
| This report describes the third year's effort on a program that has as its objective the development of nitrogen gas lubricated journal and thrust bearings that have the best potential for stable operation at temperatures to 1900 F and speeds to 60,000 rpm with low flow rates. The program concentrated on attaining quantitative performance data on dynamic rotor bearing behavior. The report summarizes equipment, instrumentation, and experimental work. Quantitative performance ... |

|
| A study is made of the attenuation of the force transmitted by an unbalanced rotor. The attenuation is achieved by a flexible bearing support. An analysis is presented of the unbalance vibrations of a flexible, symmetrical, two-mass rotor supported in fluid film bearings which in turn are mounted in flexible supports. The fluid film in the bearings possesses both flexibility and damping. The analysis takes into account both static and ... |

J. A. Edwards; NORTH CAROLINA STATE UNIV RALEIGH
|
| This research program was conducted to determine the lubrication behavior of liquid metals. The objectives of the program were to study hydrodynamic bearing theory to determine the frictional characteristics, eccentricity, and load-carrying capacity of full journal bearings over a wide Sommerfeld number range and to compare experimental data with analytical data and attempt to explain any discrepancies. The hydrodynamic characteristics of a full journal bearing, four inches long with a ... |
