 | This work was conducted as part of a USAF initiative to develop a comprehensive theory to predict pilot-induced oscillation (PIO) tendencies due to the combined effect of all influencing elements. A PIO is a very complicated phenomenon stemming from a dynamic interaction between the pilot and the aircraft. When tight control is required from the pilot, an undesired oscillation can result. However, the adaptive nature of the human pilot, makes ... |

| This report describes a series of experiments designed to study the air mass directly above the ocean in an effort to better understand the development of the atmospheric aerosols which comprise marine haze. To determine the nature of the boundary layer haze, one must first characterize the composition and size distribution of the particles that comprise the haze, identify the source(s) of those particles and specify the source strength and ... |

 | Results are reported for a measurement program designed to investigate the performance deterioration of gas turbine engines and the associated auxiliary equipment difficulties when operating in dust-laden environments. Three TF33 turbofan engines and one J57 turbojet engine have been tested with two different dust blends. The predominant damage mechanism in all of the engines was compressor blade erosion. The length of dust exposure time required to cause engine damage was ... |

E. G. Rynaski; CALSPAN ADVANCED TECHNOLOGY CENTER BUFFALO NY
|
| An investigation was made of the application of robust output observer theory to the design of flight control systems for advanced aircraft configurations. Observer theory constitutes a natural design tool because the resulting observers are in themselves unobservable and do not increase the order of the closed-loop response, thereby more closely satisfying flying qualities requirements. Examples are presented to show that the observer configuration is not unique in either the ... |

A modified numerical framework, constructed from the Lavoie model, is capable of simulating the effect of warm water patches on the formation of stratus/fog during inversion rising situations. However, the operational ... |

| Efforts to develop an implicit time-marching method for calculating the flow through a compressor blade row are reported. The flow is taken to be inviscid, and steady in blade-fixed coordinates. A conformal-mapping technique was used to generate a boundary-conforming grid, and a number of attempts were made to calculate the flow through a cascade of blades. Instabilities in the calculated results prevented the achievement of steady-state solutions. The instabilities are ... |
