摘要:
A system and method for determining thermal growth of motor or engine parts to thereupon control the clearance of motor or engine fan blades (226) is disclosed herein. In addition, a system and method for monitoring the health of a turbine engine (130), its components and sub-components is also described herein. The system(s) and method(s) described herein permit continuous monitoring during the life of the engine (130) for radial clearances and blade (226) and rotor vibration problems, which will assist in correcting and retaining performance for a longer on-wing time in operation. In addition, inconsistent engine-to-engine performance variations due to component tolerances, engine operation characteristics, and operation during extremes in ambient temperatures can be eliminated or significantly minimized when employing the system(s) and method(s) described herein.

A method of non-invasively measuring strain and temperature of an object, substantially simultaneously, using neutrons of selected energy levels is described. A pulsed neutron source is made to emit thermal and epithermal neutrons in a collimated beam directed at a target object. Temperature is monitored by observing the thermal Doppler broadening of resonances in the neutron transmission characteristic for the epithermal neutrons and strain is measured form observed made of changes to the thermal neutron diffraction pattern.

To observe an elastic material under a dynamically deformed state. [Solution ] A method for observing deformation of an elastic material 1 including rubber or elastomer, and an apparatus for capturing a projection image of the elastic material suitably used therefor. The observing method includes: a projection image obtaining step S1 of capturing a projection image of at least a part of the elastic material 1, from a direction perpendicular to an arbitrary axis of the elastic material 1, at a plurality of capture positions P around the axis; a three-dimensional image constructing step S2 of constructing a three-dimensional image 51 of the elastic material 1 from the projection images, and a step of observing the three-dimensional image 51. The projection image obtaining step S1 comprises: a deforming step S12 of deforming the elastic material 1 in predetermined cycles; a signal output step S13 of outputting an capture signal St at a predetermined specific time point during one cycle; and a capturing step S14 of capturing the projection image of the elastic material 1 based on the capture signal St. The deforming step S12, the signal output step S13 and the capturing step S14 are performed at each of the capture positions.
