Numerical investigation of abradable coating wear through plastic constitutive law: application to aircraft engines
In the field of turbomachines, better engine performances are achieved by reducing possible parasitic leakage flows through the closure of the clearance distance between blade tips and surrounding casings. Together with new technologies involving higher casing conicity for improved compression rates, direct contact is now considered as part of aircraft engines normal life. In order to avoid pos...

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Evolutionary Maintenance for Aircraft Engines
Maintenance and, in particular, maintenance policy plays a major -*art in achieving systems operational effectiveness at minimkm cost. The traditional approach to maintenance planning involves selecting optimal policies from known maintenance strategies such as scheduled inspection, preventive maintenance, corrective maintenance, oncondition maintenance etc. Using a traditional approach one may...
