Locating air leaks in manned spacecraft using structure-borne noise.
All manned spacecraft are vulnerable to leaks generated by micrometeorite or debris impacts. Methods for locating such leaks using leak-generated, structure-borne ultrasonic noise are discussed and demonstrated. Cross-correlations of ultrasonic noise waveforms from a leak into vacuum are used to find the location of the leak. Four methods for sensing and processing leak noise have been develope...
متن کاملvehicle interior structure borne noise calculation using finite element method
in this paper the interior noise level of a vehicle due to structural vibration, named structure borne noise, as a part of nvh analysis has been investigated. first structural analysis is performed and vibrational behavior of structure carried out due to power plant excitations. then interior acoustic cavity response for such excitation and resultant noise is determined. vibrational analysis is...
متن کاملWireless Sensor Node for Gas Pipeline Leak Detection and Location
Many different wireless sensor nodes for gas pipeline leak detection and location has been proposed but still there are challenges particularly on environmental issues and signal accuracy. This paper discusses theories and environmental constraints for wireless sensor nodes, a case study of Dar es Salaam Tanzania and finally presents a design and simulation results of the proposed wireless sens...
متن کاملLiquid Leak Detection Using Laser Triangulation
For liquid leak detection in machines and industry systems the non-contact laser triangulation can be applied successfully. The refraction of laser ray emitted by sensor head while entering the liquid is used. Experimental tests were carried out for machine oil. Obtained results confirm the possibility to detect oil layers with high accuracy in micrometers. In the paper the idea of a measuremen...
متن کاملTank Leak Detection Using Electrical Resistance Methods
Two field experiments were performed to evaluate the performance of electrical resistance tomography (ERT) as a leak detection method under metal underground storage tanks (UST). This paper provides a summary of the field experiments performed under a 15 m diameter steel tank mockup located at the Hanford Reservation, Washington. Two different leak events were created. About 3800 liters of sali...
