|
| Polarimetric Synthetic Aperture Radar (SAR) data from RADARSAT-2 is analyzed for detection of soils susceptible to helicopter brownout. Helicopter brownout occurs when downwash disturbs the dust and sand beneath the aircraft during takeoff, landing, and low altitude operations. Brownout may lead to pilot spatial disorientation and loss of control, causing helicopter damage or destruction, as well as personnel injury or death. The likelihood of helicopter brownout is related to soil ... |

| A number of currently proposed helmet-mounted display (HMD) designs relocate image intensification (I2) tubes to the sides of the helmet. Such a design approach induces a visual condition referred to as hyperstereo vision (or hyperstereopsis). This condition manifests itself to the user as an exaggerated sense of depth perception, causing near- to mid-range objects to appear closer than they actually are. Hyperstereopsis is potentially a major concern for helicopter operations ... |

| Unmanned aerial vehicles are no longer used for just reconnaissance. Current requirements call for smaller autonomous vehicles that replace the human in high-risk activities. Many times these activities are performed in GPS-degraded environments. Without GPS providing today's most accurate navigation solution, autonomous navigation in tight areas is more difficult. Today, image-aided navigation is used and other methods are explored to more accurately navigate in such areas (e.g., indoors). This thesis ... |

To meet this objective, an experimental program using high-resolution particle image velocimetry was performed. High-resolution planar contours of the instantaneous and mean velocity field on a dynamically pitching NACA 0012 airfoil operating in the Texas A&M University large-scale wind tunnel are planned. ... |

| This report describes the results of the first spiral of a study conducted by the NAVAIRWARCENWPNDlV Fire Science and Technology Office, to review the suitability of the Lockheed Martin Littoral Combat Ship design to obtain permission to operate helicopters with fewer personnel than required by the NAVAIR 00-80R-14 NATOPS U.S. Navy Aircraft Firefighting and Rescue Manual. The study, conducted from April through June 2006, included a survey of LCS ship ... |

| This research presents the development of an on line linear time periodic rotor vibration controller. The Cramer-Rao bound is developed for a linear time periodic system in order to identify the quality of identified system parameters, which are used in system models for controller development. The methods developed in this work allow model parameters can be verified for accuracy and likewise adjusted to improve controller accuracy. |
