Radiation Hazards and Manned Space Flight.
T HE POTENTIAL medical hazards of man's venture into space will span a number of disciplines in regard to the pathology and deranged physiology to which the human body may be subject in travel beyond the earth's atmosphere. Not the least hazard is that having to do with the effects of radiation to be encountered in free space. This problem is one which is receiving considerable attention from a...
متن کاملRadiation Mapping in Post-Disaster Environments Using an Autonomous Helicopter
Recent events have highlighted the need for unmanned remote sensing in dangerous areas, particularly where structures have collapsed or explosions have occurred, to limit hazards to first responders and increase their efficiency in planning response operations. In the case of the Fukushima nuclear reactor explosion, an unmanned helicopter capable of obtaining overhead images, gathering radiatio...
متن کاملHelicopter Rotor Blade Monitoring using Autonomous Wireless Sensor Network
The advancement on Wireless Sensor Networks for vibration monitoring presents important possibilities for helicopter rotor health and usage monitoring. While main rotor blades account for the main source of lift for helicopters, rotor induced vibration establishes an important source for understanding the rotor performance and blade condition. A discussion on the dual character of blades as rot...
متن کاملUsing Triaxial Accelerometer Data for Vibration Monitoring of Helicopter Gearboxes
Typical vibration monitoring systems for helicopter gearboxes rely on single-axis accelerometer data. This paper investigates whether triaxial accelerometers can provide crucial flight regime information for helicopter gearbox monitoring systems. The frequency content of the three different directions is compared and analyzed using time-synchronously averaged vibration data. The triaxial data a...
متن کاملCondition Monitoring of Helicopter Drivetrain Components Using Bispectral Analysis
In this paper, bispectral analysis of vibration signals is used to assess health conditions of different rotatingcomponents in an AH-64D helicopter tail rotor drive train. First, cross-bispectral analysis is used to investigate drive-shaft faulted conditions -namely misalignment, imbalance, and a combination of misalignment and imbalance -with respect to a baseline case. The magnitude of the cr...
