Identification of rotor bearing parameters using vibration response data in a turbocharger rotor

Turbochargers are most widely used in automotive, marine and locomotive applications with diesel engines. To increase the engine performance nowadays, in aerospace applications also turbochargers are used. Mostly the turbocharger rotors are commonly supported over the fluid film bearings. With the operation, lubricant properties continuously alter leading to different load bearing capacities. T...

Minimal haemodynamic system model including ventricular interaction and valve dynamics.

Characterising circulatory dysfunction and choosing a suitable treatment is often difficult and time consuming, and can result in a deterioration in patient condition, or unsuitable therapy choices. A stable minimal model of the human cardiovascular system (CVS) is developed with the ultimate specific aim of assisting medical staff for rapid, on site modelling to assist in diagnosis and treatme...

Adaptive Risk Refinement Methodology for Gas Turbine Engine Rotor Disks

Probabilistic fracture mechanics is a well-established method for predicting the probability-of-fracture (POF) of gas turbine engine rotor disks subject to low-cycle fatigue. An adaptive risk refinement methodology (ARRM) was developed to automate zone discretization and refinement that are typically associated with this approach. ARRM generates initial meshes using an adaptive nodal selection ...

Rocket Engine Failure Detection Using System Identification Techniques

HPFT HPFTP This paper presents the; theoretical foundation and HPOP application of two univariate failure detection HPOT algorithms to Space Shuttl,; Main Engine (SSME) test LPFP firing data. Both algorithms were applied to data LPOP collected during steady-sutte operation of the engine, m One algorithm, the time s_'.ries algorithm, is based on MCC time series techniques and involves the comput...
