Tornado OLMOS Cost Benefit Study.

The Monitoring System OLMOS was introduced on the military Weapon System Tornado in order to increase flight safety, system readiness, and logistical utilization. The monitoring of engine performance and inherent life consumption of the airframe and the engine is the prerequisite for a performance and stress oriented on condition maintenance concept. The study gives a brief system overview and shows the cost benefit trade off on airframe fatigue, static overload, engine fatigue, and engine operation monitoring. A sensitivity analysis shows the various effects using a primitive counter versus a complex integrated system. Portability of the monitoring system from Tornado to other systems is being considered as well as the expansion potentials.
