Models of Closed-Loop Use/Repair Cycles with Application to the DD-963 Main Propulsion Engines

摘要

The report describes and compares two models which may be used as tools in making logistic support decisions for closed-loop systems, such as the use/repair cycle of the LM-2500 gas turbine engines. The models are then used to study the effect of changes in various system parameters. The models are a computer simulation developed by Cushing, Gautier, and Long and an analytical model developed by Koenigsberg. The steady-state behavior of both models is essentially the same, with the analytical model consistently more conservative than the simulation model. (Author)
