Book excerpt: The vibration of turbomachinery blades is an important phenomenon to understand, observe and predict and is the reason for developing a tip timing measurement system. Vibration leads to High Cycle Fatigue (HCF), which limits blade durability and life. HCF can result in blade failure, having expensive consequences for the engine involved. The traditional method for monitoring blade vibration under test conditions is to use blade mounted strain gauges. However, strain gauges are costly and time consuming to install. They have a limited operating life as they are subjected to the harsh on-engine conditions. Only a limited number of blades can be monitored with strain gauges as the number that can be used is limited by the number of channels in the slip ring or telemetry. They can also interfere with the assembly aerodynamics. Consequently non-intrusive alternative techniques such as tip timing are sought. Capacitance probe based clearance measurement systems see widespread use in turbomachinery applications to establish rotor blade tip clearance. This thesis reports investigations into an alternative and additional use in aero-engine rotor blade tip timing measurement for these commercially available systems. Tip clearance is of great importance in the gas turbine industry; this is clear from the fact that gas turbine efficiency has an inverse relationship with tip clearance. Large tip clearance leads to large leakage flows, hence low efficiency, thus the common use of the capacitance probe clearance measurement technique in monitoring turbomachinery. Optical systems have been successfully used to measure rotor blade tip timing on test rigs with several optical probes mounted equally spaced around the turbomachine casing. However, there are practical problems associated with mounting such monitoring systems on in-service jet engines. Optical probes require high maintenance to keep the lenses clean, probably incorporating a purge air system to keep the lenses from fouli.

Available in PDF, EPUB and Kindle. Book excerpt: Two forms of cavitation have been recorded and attributed to the tip clearance flow. Cavitation resulting from this flow in the clearance area between the blade end and guide wall has been termed 'gap cavitation'. A second form of cavitation originates from the interaction of the tipleakage flow and main flow in the blade passage. This form of cavitation termed the 'tip vortex cavitation' occurs initially as a small 'feather' of cavitation attached to the leading edge tip of the blade, and as the local pressure is further reduced, the feather grows into a distinct cavity which extends from the leading edge of the blade and diagonally across the blade passage. Both forms of cavitation are considered in this report but primary effort was directed towards a study of 'gap cavitation'. (Author).
